RAID: The Upgrade Your Server Deserves   no comments

RAID: The UPGRADE Your Server Deserves

A Redundant Array of Inexpensive Disks (RAID) is a system that utilizes multiple hard drives simultaneously to act as a single storage volume. Using a controller that manages the operation of the hard drives, you can configure a RAID array to do the following:

  • Stripe data across multiple drives, reading and writing data across all drives simultaneously for double the performance — or more — when reading or writing large blocks of data
  • Mirror data across multiple drives so that each drive in the array contains an exact copy of the same data
  • Create Parity blocks on each drive in the array, making it possible to recover the lost information if a drive fails — and to keep the array running while rebuilding the failed drive

RAID has several implementations — or “levels” — that utilize striping, mirroring, parity or a combination of the three. We’ll explain those more fully later in the article, but for now there’s one thing you need to know: If you have a home or business server, you need RAID. RAID is the one solution that can make your server faster, do a better job of protecting your data and continue operating while you rebuild data after disk failure.

Although an exhaustive list of all RAID levels is outside the scope of this article, this brief list should help to explain the features and benefits of RAID in greater detail:

 

RAID 0

A RAID 0 array requires at least two hard drives. In RAID 0, the controller splits all data equally across all hard drives. Each drive works simultaneously during read and write operations, increasing the speed of the volume to far greater than that of a single hard drive.

Strengths and Weaknesses: A RAID 0 array excels in increasing a server’s storage performance. However, all data in a RAID 0 array is lost if one drive fails. You can add additional drives to a RAID 0 array to increase its performance further, but adding more drives further increases the risk of failure.

 

RAID 1

In a RAID 1 array, every hard drive contains the same data and the controller writes to all drives simultaneously. A RAID 1 array provides excellent data redundancy because all of the data survives unless every drive in the array fails.

Strengths and Weaknesses: In addition to data redundancy, RAID 1 can slightly increase a server’s read performance. When the controller requests data, the drive that can access the data most quickly will retrieve it. However, RAID 1 provides no increase in storage capacity past that of the smallest hard drive in the array because each drive contains the same data. In addition, the slowest hard drive determines the write speed of the entire array.

 

RAID 5

A RAID 5 array stripes the data across multiple drives like RAID 0. However, every hard drive also carries parity data for each block written. Using the parity data, the controller can rebuild the entire array if one drive fails — and the array can continue working during the rebuild process.

Strengths and Weaknesses: The greatest strength of RAID 5 is that it offers increased reliability without sacrificing a great deal of storage capacity. Unlike RAID 1, the total capacity of a RAID 5 array increases each time you add a hard drive. However, parity data does take up some space. A RAID 5 array with four 1 TB hard drives will have a total capacity of about 3 TB.

RAID 5 offers better read performance than a single drive because the striping allows multiple drives to read simultaneously. However, the write performance of RAID 5 is relatively poor because of the extra time required to write parity data.

 

RAID 6

RAID 6 is similar to RAID 5 in design, but it devotes an amount of storage equal to that of two hard drives — rather than one — to parity so it can tolerate the failure of two drives without losing data.

Strengths and Weaknesses: A RAID 5 array can tolerate the loss of any one drive. However, hard drive manufacturers state that about once every 12.5 TB, a hard drive will encounter an unrecoverable read error. If you have a RAID 5 array with four 4 TB drives and one drive fails, the remaining capacity of the array is about 12 TB. If one of the remaining three drives experiences a read error when rebuilding the array, the rebuild operation will fail. If you use more hard drives — or larger hard drives — the chance of failure is greater. So, RAID 6 is far more reliable than RAID 5 for very large RAID arrays. However, because RAID 6 doubles the amount of parity data, write operations are slower.

 

RAID 10

RAID 10, or RAID 1+0, is essentially the combination of RAID 1 and RAID 0. It combines disk striping and disk mirroring to provide redundancy and performance. Due to it’s incredible performance benefits, RAID 10 is one of the most ideal solutions, especially for intense applications and databases.

Strengths and Weaknesses: The greatest strength of RAID 10 is that it offers maximum performance while also maintaining redundancy. The only disadvantages of RAID 10 are that it requires a minimum of four disks and only 50% of the disk space is usable due to mirroring.

 

RAID has become a vital necessity for any business looking for safety and performance when it comes to their website and/or critical company data. If your business is currently running on a server without RAID, you risk not only data loss, but also the added performance that can separate you from your competitors. Now is the time to upgrade your business to a RAID solution.

At TurnKey Internet, RAID upgrades are available on all of our Dedicated Servers. Best of all, our latest Best Value Dedicated Server already includes RAID 10, making your upgrade even easier! Start enjoying the added performance and safety of RAID today.

Shared Hosting vs Dedicated Server   no comments

Posted at May 9, 2017 @ 10:09am Web hosting

Shared Hosting vs Dedicated Server

When you are just getting started, a shared web hosting plan is typically enough to help you meet your goals. It gives you a platform to collect leads, showcase your company and sell your products and services. The problem with shared hosting, though, is that it comes with limited performance and limited room for growth. Although it’s enough while your business is still small, you might want to think about upgrading as your business starts to grow. Many people have a hard time deciding when to make the switch, and if you can relate to this problem, then the following information will get you started in the right direction. You will learn about the benefits of using a dedicated server, but you will also get a clear picture of when to take action.

 

With most shared hosting plans, your performance can be impacted by the way that other people on the server use their resources. If someone else’s website is getting a lot of traffic or being attacked, then your website might slow down or even go offline for a while. If you depend on your site to generate sales, then this downtime is unacceptable. When your customers want to make a purchase, they are not always going to wait for your content to come online again. So any performance issues that you experience can hurt your profitability. A dedicated server will help you avoid that problem by providing you with exclusive resources. A dedicated server also enables your business to customize and configure the performance resources and software based on your company’s unique needs. Things like CPUs, memory, and storage space, can all be customized and upgraded on a dedicated server. With shared hosting, you are limited to the software already installed on the server, and sometimes it may lack a requirement or feature your business needs. But with a dedicated server, you have full flexibility over which software your server runs, even down to the Operating System (Windows, Linux, etc).

 

Another downside of shared hosting is the lack of Administrative or root access to the server. This limitation affects what software you can install as well as the settings and options that you can configure on the server. This can greatly impact the potential of what you are able to do with your website. However with a dedicated server, you do have full root or admin access, giving you the ability to better monitor and troubleshoot your website, with full access to your virtual server’s logs. With a dedicated server, you have exclusive access and can dictate who shares that access. This allows you to better secure the contents on your server and alleviates the concerns of sharing a server with malicious or careless users. Also because you have full control over the server, you can better enhance and customize its security based on your unique needs.

 

If you have decided that you need to upgrade, then consider it a good thing. Needing more resources means that your business is growing and that you are attracting plenty of new customers. Having a dedicated server will help you accommodate even more web traffic, and you will not need to worry about losing sales or customers due to downtime. The speed and performance of a dedicated server will also help you maintain a professional image, which will enhance and preserve your reputation. Some business owners procrastinate when they need to upgrade their website, but doing so hurts them more than they likely suspect. Ensuring that your web hosting solution is capable of meeting your needs is a vital factor when it comes to getting the most from your business, and you can get started right away.

What is a Dedicated Server?   no comments

Posted at May 2, 2017 @ 11:00am Web hosting

What is a Dedicated Server?

A dedicated server (also known as a bare metal server) offers the ultimate combination of performance, value and security for your web hosting needs. A dedicated server provides you with exclusive access to all the physical hardware in the server (CPU, Ram, Disk, Network Port, and the physical chassis of the server). Nothing on the server is shared with any other clients in any fashion.

For most clients with a new website or business, a Shared Hosting solution is enough to get off the ground. But, for many there comes a point when shared hosting just isn’t enough. The most obvious sign that it’s time for an upgrade is when your website has started regularly requiring more bandwidth or resources than your current plan provides. If your business increases in popularity, thus suddenly sending more visitors to your website, it could temporarily go offline. However, upgrading your shared hosting to a dedicated server can prevent this.

Regardless of the content of your website, if you’re worried about stability, a dedicated server is always the safest bet. Below you will find a summary of all the benefits a dedicated server provides.

 

Performance

Server and network response times in a shared hosting environment depend highly on the activity of other users and websites with whom you share space and resources. With a dedicated server you have significantly faster response and page load times because all the systems resources (such as CPU, disk, RAM and network bandwidth) are controlled and utilized solely by the applications on your server.

 

Reliability

With a dedicated server, you have unlimited access to the operating system, server resources and software applications. This gives you a reliable way to manage the needs of your website and users: it’s all there when you need it.

 

Security

Dedicated servers provide better security than any other form of hosting since you are the only one with the root “administrative” access to your resources and can configure customized security policies, such as firewall protection, user-level permissions and even restrict the types of applications that run on the server. With shared hosting, the users you share space with could jeopardize the security of your website and data.

 

Customization

Dedicated servers offer unlimited customization and flexibility to meet your hosting application needs. You have access to fine tune and optimize all aspects of the server such as custom versions of Apache, PHP, MySQL, or custom database configurations to suit your application needs, providing substantial performance gains over any other form of hosting. You can install, remove, or modify any applications you wish.

 

Dedicated servers are the best solution for those that are serious about their web site and want the assurance that hardware, software and resources are dedicated exclusively to them. If you are considering hosting numerous domains, a high traffic site, an e-commerce site, have sensitive data contained in your site or simply want more speed, power and control, it’s time to upgrade to a dedicated server.

Effective Security Measures For Your Server   no comments

Posted at Apr 4, 2017 @ 10:49am Web hosting

If you run a server, especially for your business or organization, security should be a top priority. Whether the server exists to host files for a website or is networking computers for an office, it needs to be protected from malicious software, exploits and hackers. Failing to secure a server can lead to lost or corrupted data, damage to devices connected to the network and unauthorized individuals getting access to sensitive data. Below are various security measures that you can employ on your server that are extremely effective.

 

Review & Modify Default Settings

Programs running on your server, such as control panels (cPanel, Plesk), CMS (WordPress, Joomla, etc.) and even the operating system, contain various default settings  that need to be reviewed and if necessary modified. They include everything from preset usernames and passwords for admin access to default connection ports. Anything that is left as set up by the software manufacturer may be used as a way to gain easier access to a system. Even leaving the URL for admin access to a server or programs on the server can make it easier for hackers to get in. There are hacking tools that specifically scan websites and servers for default URLs and folders, so changing default login locations is important. On this same basis, it’s a good idea to make sure that directories are protected so that people cannot see their contents.

 

Active Monitoring

A critical requirement to properly managing a server is knowing what is happening with it at all times. Even the best security software cannot prevent all intrusions, and hackers are constantly figuring out new ways to exploit and circumvent security systems. Therefore, it’s important that activity on a server is always being monitored. Things that normally indicate a problem include incredibly high data transfer or processing power use as well as multiple failed login attempts. Brute force hacking involves trying to login to a system over and over again with different login and password combinations. In addition to draining system resources, it can also eventually allow a hacker to find a combination that lets them into your system. Real-time monitoring can help detect these issues and alert the appropriate people, and it can also shut down brute force login attempts.

 

Passwords & Permissions

Another important server security measure is to ensure that all passwords, especially the root and/or Admin passwords, are complex and that people are only given access to areas that they need to do their job. Aside from malice, giving an intern administrative access to databases could lead to major problems through simple error. It’s also recommended to change your passwords on a regular basis, even if they are robust.

There are a number of ways to tackle the issue of making sure passwords are complex enough, including using computer generated passwords or using passphrases. Computer generated passwords normally require certain characters, length and require a combination of upper and lower case letters; passphrases are combinations of words, and they tend to be easier to remember and more secure than passwords. There should also be a set time that passwords expire, which will require users on the network to change them on a regular basis.

Along with ensuring that people are only given access to parts of a server that they need to have, it’s important that permissions are updated when people leave a job or move to a different part of the company. This can be done with proper database management and doing occasional audits to ensure that access levels are appropriate.

 

Updates

One way that hackers get into many servers is by going through weak points that developers did not notice when creating an application or an operating system. This is why both computers and mobile devices need regular updates. Along with offering new options, updates close off back doors and holes in the security of software. Therefore, it’s important that all software hosted on your server is kept up to date. For web hosting servers, that means content management systems (CMS) and the plug-ins the CMS uses must be kept current. Many operating systems and software applications can be set up to update automatically, but if you’re not comfortable with that, it’s important that you have some way of being notified when important changes are available.

 

For those of you who feel there’s just not enough time in your day to employ these server security measures, or if you just prefer someone else does it for you, at TurnKey Internet we got your back. We offer Fully Managed solutions that include Server Hardening. We’ll take care of securing and protecting your server so you can focus on running your business.

Why Website Speed Matters   no comments

Posted at Feb 7, 2017 @ 11:32am Web hosting

Why Website Speed Matters

If you’re in a store and ready to check out but you can’t find someone to help you, chances are you’ll stick around. You may even wait quite a while since you’ve gone through all the trouble of going to a store and selecting which items you want. However, if you’re waiting a long time for a website to respond, you can be on another site making the same selections within seconds.

For this reason, it’s essential that your website runs quickly and loads within mere seconds. People have a large selection of websites that they can get information from or do business with, and you need to be sure that your site is providing what people want very quickly. Additionally, it’s not just sites that sell items that need speedy load times. Sites that generate revenue from ads also need to load quickly to prevent the loss of income.

 

It Can Lower Your Conversion Rate

Studies show that people are steadily becoming less patient when it comes to waiting for web pages to load; 47 percent of people expect a website to load in two seconds or less. For mobile sites, you are given about three seconds before more than half of visitors say they will leave. Even if you’re getting people to stick around, a slow load time can drop your conversion rate.

A study done by Amazon showed that just a 0.1 second slower load time resulted in a one percent decrease in sales. While Amazon is enormous and your website may not be able to generate that much traffic or sales, it shows that even tiny slowdowns can still have a tangible effect on your business.

 

Search Engine Ranking

If you run a business website, you’re probably at least familiar with the concept of search engine optimization, which involves signaling to search engines that people who are searching for particular terms or phrases would benefit from visiting your site. Google, and other search engines, include user experience as a metric when determining where your website will end up in search engine results.

User experience includes a number of things, including the quality of content on a site, if it’s easy to navigate and how quickly the website loads. Google doesn’t generally release specific information about how metrics are weighted, but a slow website can dramatically reduce your user experience score. With SEO being so competitive, the last thing you want is a slow website dragging your ranking down.

 

User Experience

One of the reasons that user experience is a part of many search engine ranking metrics is because people tend to not return to websites that worked poorly for them. Research done by Statista indicates that a quarter of shoppers will abandon an online shopping cart if the website is too difficult to use.

Having a slow website can also make visitors do more than just wait. It can also keep certain parts of your site from working because scripts still need to load. Someone may fill out a form or attempt to add an item to a shopping cart and get an error or find that nothing is happening.

Additionally, when a website is slow, it may not load properly or things on the page may start adjusting themselves, changing the locations of images and text as people are trying to read or use the site. These types of frustrations can easily send someone away from your site with a commitment to never return.

 

The Need For Speed On Mobile

Mobile users can be even more impatient than people on PCs. With the number of individuals using mobile devices to both surf the web and make purchases, it’s essential that you’re not driving away customers and visitors with a slow site. In addition to needing to create mobile and desktop versions of your site, you need to be sure that mobile versions load quickly and aren’t just designed to fit on a smaller screen.

People on mobile devices often have data caps, and although powerful, smart phones have far less processing power than computers. Images need to be shrunk in terms of both pixels and file sizes, and scripts need to be kept down to the minimum required for the site to function. Along with rating user experience for desktop websites, Google also measures user experience for mobile sites. Furthermore, in the last year, they’ve started ranking mobile friendly sites higher when people do searches on a mobile device.

 

Loss of Ad Revenue

Depending on the ad network that your website is hosting advertising from, you may only get credit for ad views if the ad loads properly, if the visitor to the page has the ad show up on their screen or both. If your website is very slow, ads may not be loading properly, depriving you of revenue. Google found that 25 percent of mobile sites with load times under five seconds had higher ad revenue.

 

Resolving Your Speed Problems

Whether you have a slow site or would just like your site to run faster than it already is, one of the first things you should look at is cutting down on scripts and reducing the size of image and media files. Scripts can slow down even a bare bones site because they use a server’s bandwidth, processing power from the server and processing power from the computer they are being loaded on. Unless your site – and the page that someone is on – needs a script or function to run, consider ditching it.

Media files can also dramatically increase the amount of time that it takes for a site to load. Instead of eliminating image files, see if you can’t compress them or use another file type that results in a smaller image. A small loss in image quality can cut an image’s file size in half.

Another consideration is the server or hosting provider you’re using. You may need more bandwidth or processing power, and if you’re using shared hosting, it may be time to upgrade to a VPS or Dedicated Server solution.

Top 5 Benefits of a Dedicated Server   2 comments

Posted at Jan 31, 2017 @ 10:19am dedicated servers,Web hosting

Benefits of Dedicated Servers

Whether you’re an online business or an individual looking for more power, flexibility, and control over your web hosting solution, the answer for you may be a dedicated server. With a dedicated server, your business has exclusive use of that server’s resources. You also have the flexibility of customizing the server to meet your individual performance and security requirements. To fully understand why a dedicated server is the better solution for you or your business, let’s take a look at the top five benefits they provide.

 

1. Exclusive Resources

When using a dedicated server, every bit of power, storage, and bandwidth is exclusive to you and no one else. Not only will this give your business more room to work with and expand, it will also prevent issues with your site caused by other websites. For example, if you’re site is hosted on a shared server where there is another website that is being attacked or hogging up resources, this can affect the performance of your company’s site.

 

2. Dedicated IP Address

Each dedicated server comes with its own dedicated IP address. With shared hosting, your site may be sharing an IP address with multiple websites. If your website happens to share an IP with a site that spams or contains malware, this can cause multiple problems. Your website can end up getting blocked, your email rejected as spam, even your search results can be affected. Another thing to consider is whether or not you’ll be running an e-commerce or selling things on your site. If so, you will need to have an SSL for your site, which in turn requires a unique dedicated IP.

 

3. Customization

A dedicated server allows your business to customize the hardware and software based on your company’s unique needs. Things like CPU, Memory, Hard Drive, even the speed of the server’s network port, can all be customized and upgraded on dedicated servers. With shared hosting, you are limited to the software already installed on the server, and sometimes it may lack a requirement or feature your business needs. But with a dedicated server, you have full flexibility over which software the server runs, even down to the Operating System.

 

4. Better Access

Another downside of shared hosting is the lack of Administrative or root access to the server. This limitation affects what software you can install as well as the settings and options that you can configure on the server. This can greatly impact the potential of what you are able to do with your website. Another advantage of administrative/root access is the ability to better monitor and troubleshoot your website, with full access to the server’s logs.

 

5. Better Security

With a dedicated server, you have exclusive access and can dictate who shares that access. This allows you to better secure the contents on your server and alleviates the concerns of sharing a server with malicious or careless users. Also because you have full control over the server, you can better enhance and customize its security based on your unique needs.

 

Now if you’re worried that you’re not tech savvy enough to run your own dedicated server, consider the option of going with a Managed Dedicated Server solution, which will provide many additional benefits on top of what’s listed above. Also if cost is a concern, check out our latest Best Value Dedicated Servers. There are countless other advantages to using a dedicated server, however the 5 above are some of the most notable. So before you decide to host your website on a shared server, consider the added flexibility, reliability, and performance that only a dedicated server can provide.

8 Tips to Get Your Website Ready for the Holidays   1 comment

Posted at Nov 1, 2016 @ 10:10am Holidays,Web hosting

holiday-ready

As the holiday season draws near, it’s time to start thinking about updating your website to capitalize on the increased traffic that often accompanies this time of year. Satisfied customers and a successful holiday season will make any business owner smile, and your website can play a big role in making that happen. Taking extra time to prepare now is a good way to avoid technical problems and other issues during the holidays.

 

Optimize for Mobile Devices

Thanks to the growth of smartphones and other mobile digital devices, online shoppers don’t have to be chained to their computer desks to check off purchases from their holiday shopping lists. Developing a simple and functional theme specifically for your mobile users can increase your potential customer base. The easiest way to do this is to make use of responsive designs. With a responsive design, your website will modify itself automatically to create the optimal layout for the customer’s mobile device; these designs can accommodate both smartphones and tablets. Due to the smaller screen size typical of mobile devices you probably won’t be able to maintain the exact same design from your desktop version, but you can still use the same branding and color scheme.

 

Improve Your Website’s Loading Time

You may want a website with all the latest bells and whistles, but consider your website’s performance before you load it up with high-resolution graphics and elaborate scripts. Sluggish loading times on your website frustrate your customers and may encourage them to shop elsewhere. Before the holidays start, have your technical support team run tests on your website to see how fast each page loads for the average user. Changes to your design, such as reducing large images and eliminating complex coding scripts, can help your website perform better. You can also opt for a better hosting package for your website to see even more improvement in loading speeds.

 

Secure Customer Data

Shopping online is always risky; some websites don’t safeguard customers’ data properly, putting these individuals at risk for identity theft and other issues. Investing in robust security software is a good way to protect your customers’ important data. Your technical support staff should keep apprised of the latest developments in online security to help your customers stay safe. To help alleviate your customers’ concerns, you can include information on your website about the security protocols that you use and offer tips on how your customers can shop online safely.

 

Offer Friendly Customer Support

Browser problems, incorrect stock levels and missing orders are just some of the common customer issues your staff will need to work through. Having enough staff on hand is an essential ingredient to helping your website survive the holidays. If possible, offer a live chat support option to those who are currently browsing your website. Keep an eye on your social media profiles in case a customer tries to reach you through those networks. Some customers may prefer to use email to get in touch with you; using a ticket system to handle incoming customer emails is a good way to keep track of issues. Help your staff to cultivate a customer-centric attitude, and try to anticipate common problems so that you can develop solutions ahead of time.

 

Boost Your Search Engine Presence

Improving your search engine rankings before the holidays begin can help fuel your success during the holiday rush. There are many ways to help boost your search engine rankings, starting with updating older pages on your website; offering fresh information to your visitors is a good way to impress search engines and show that your website is active. Adding special features, such as a blog, can also help. If your blog content is particularly noteworthy, you can expect more traffic to head your way. Your blog content should offer something useful to readers, such as tips for using your products.

 

Prepare a Festive Look

A festive design for your website encourages your customers to start thinking about the holidays. You don’t need to spend excessive money on a festive look; changing some pictures and making some cosmetic changes, such as altering the font color, can help dress up your website. Your holiday look should also include banners displaying any specials you plan to run, including discount codes.

 

Brush Up Your Social Media Presence

Social media networks offer an excellent way to connect with individual customers, generate buzz about your products and direct traffic to your website. Don’t let your social media networks sit unused with only a link to your website; update them frequently and interact with your customers. Make sure your profile on each platform matches so that you have cohesive branding. As the holidays draw near, using social media to announce your specials will help you get more interest from potential customers.

 

Beef Up Your Website’s Server

If your website is unable to handle massive amounts of traffic at once, a crowd of shoppers on big sales days could lead to sluggish performance or an outright crash. Major server problems are not something to be taken lightly; investing in the right server infrastructure for your expected traffic is a good way to avoid these issues. Shared hosting can work for you if your business is small. If your customer base is larger, you might need a dedicated server to keep your website afloat during the holidays. Dedicated hosting costs more than shared hosting, but your site won’t be at the mercy of problems caused by other sites on the server.

 

Examining every aspect of your website before the holidays arrive can help you prepare a strategy to improve customer satisfaction and your own business success. A good website requires many things, including fast loading times, quality customer service and security. Working on these elements early can ensure that your website is ready long before your customers even start to think about tackling their holiday shopping lists with your business.

RAID: Why Your Server, Website and Business Needs It   no comments

Posted at Aug 29, 2016 @ 9:50am hardware

raid-servers

As hard drives have grown in capacity, backing entire systems up to non-volatile media such as tape has grown increasingly impractical. The amount of tape required to maintain a seven-day rotating backup of a modest server with only a few hard drives, for example, is financially unfeasible for most businesses.

So, what do most businesses do? They compromise. They back up all of their data to a single set of tapes — and if you encounter a failure with your one set of tapes during the data recovery process, you’ve got a catastrophe on your hands. It’s better than not backing data up at all, but only marginally. Which brings us to RAID.

 

RAID: A Better Solution

A Redundant Array of Inexpensive Disks (RAID) is a system that utilizes multiple hard drives simultaneously to act as a single storage volume. Using a controller that manages the operation of the hard drives, you can configure a RAID array to do the following:

  • Stripe data across multiple drives, reading and writing data across all drives simultaneously for double the performance — or more — when reading or writing large blocks of data
  • Mirror data across multiple drives so that each drive in the array contains an exact copy of the same data
  • Create Parity blocks on each drive in the array, making it possible to recover the lost information if a drive fails — and to keep the array running while rebuilding the failed drive

RAID has several implementations — or “levels” — that utilize striping, mirroring, parity or a combination of the three. We’ll explain those more fully later in the article, but for now there’s one thing you need to know: If you have a home or business server, you need RAID. RAID is the one solution that can make your server faster, do a better job of protecting your data and continue operating while you rebuild data after disk failure.

 

RAID Levels

Although an exhaustive list of all RAID levels is outside the scope of this article, this brief list should help to explain the features and benefits of RAID in greater detail.

 

RAID 0 (Striping)

A RAID 0 array requires at least two hard drives. In RAID 0, the controller splits all data equally across all hard drives. Each drive works simultaneously during read and write operations, increasing the speed of the volume to far greater than that of a single hard drive.

Strengths and Weaknesses: A RAID 0 array excels in increasing a server’s storage performance. However, all data in a RAID 0 array is lost if one drive fails. You can add additional drives to a RAID 0 array to increase its performance further, but adding more drives further increases the risk of failure.

 

RAID 1 (Mirroring)

In a RAID 1 array, every hard drive contains the same data and the controller writes to all drives simultaneously. A RAID 1 array provides excellent data redundancy because all of the data survives unless every drive in the array fails.

Strengths and Weaknesses: In addition to data redundancy, RAID 1 can slightly increase a server’s read performance. When the controller requests data, the drive that can access the data most quickly will retrieve it. However, RAID 1 provides no increase in storage capacity past that of the smallest hard drive in the array because each drive contains the same data. In addition, the slowest hard drive determines the write speed of the entire array.

 

RAID 5 (Parity)

A RAID 5 array stripes the data across multiple drives like RAID 0. However, every hard drive also carries parity data for each block written. Using the parity data, the controller can rebuild the entire array if one drive fails — and the array can continue working during the rebuild process.

Strengths and Weaknesses: The greatest strength of RAID 5 is that it offers increased reliability without sacrificing a great deal of storage capacity. Unlike RAID 1, the total capacity of a RAID 5 array increases each time you add a hard drive. However, parity data does take up some space. A RAID 5 array with four 1 TB hard drives will have a total capacity of about 3 TB.

RAID 5 offers better read performance than a single drive because the striping allows multiple drives to read simultaneously. However, the write performance of RAID 5 is relatively poor because of the extra time required to write parity data.

 

RAID 6 (Additional Parity)

RAID 6 is similar to RAID 5 in design, but it devotes an amount of storage equal to that of two hard drives — rather than one — to parity so it can tolerate the failure of two drives without losing data.

Strengths and Weaknesses: A RAID 5 array can tolerate the loss of any one drive. However, hard drive manufacturers state that about once every 12.5 TB, a hard drive will encounter an unrecoverable read error. If you have a RAID 5 array with four 4 TB drives and one drive fails, the remaining capacity of the array is about 12 TB. If one of the remaining three drives experiences a read error when rebuilding the array, the rebuild operation will fail. If you use more hard drives — or larger hard drives — the chance of failure is greater. So, RAID 6 is far more reliable than RAID 5 for very large RAID arrays. However, because RAID 6 doubles the amount of parity data, write operations are slower.

 

RAID 10 (Mirroring + Striping)

RAID 10, or RAID 1+0, is essentially the combination of RAID 1 and RAID 0. It combines disk striping and disk mirroring to provide redundancy and performance. Due to it’s incredible performance benefits, RAID 10 is one of the most ideal solutions, especially for intense applications and databases.

Strengths and Weaknesses: The greatest strength of RAID 10 is that it offers maximum performance while also maintaining redundancy. The only disadvantages of RAID 10 are that it requires a minimum of four disks and only 50% of the disk space is usable due to mirroring.

RAID has become a vital necessity for any business looking for safety and performance when it comes to their website and/or critical company data. If your business is currently running on a server without RAID, you risk not only data loss, but also the added performance that can separate you from your competitors. Now is the time to upgrade your business to a RAID solution. At TurnKey Internet, RAID upgrades are available on all of our Dedicated Servers. Best of all, our latest Best Value Dedicated Server already includes RAID 10, making your upgrade even easier! Start enjoying the added performance and safety of RAID today.

Dedicated Server: 4 Reasons Why Your Business Needs One   no comments

Posted at Aug 16, 2016 @ 11:47am dedicated servers

dedicatedserverblog

Both large and small businesses are faced with a wide variety of choices and options when it comes to finding a server and hosting solution for their website, company email and data. One option is shared hosting, in which a single server’s resources are shared by a number of different websites and users.

However, if you’re a business looking for more power, control, and flexibility, the solution for you may be a dedicated server. With a dedicated server, your business has exclusive use of that server’s resources. You also have the flexibility of customizing the server’s CPU, RAM, and disk space based on the needs of your business.

Let’s take a look at 4 specific advantages of choosing a dedicated server:

 

No Shared Resources

When using a dedicated server, every bit of power, storage, and bandwidth is exclusive to you and no one else. Not only will this give your business more room to work with and expand, it will also prevent issues with your site caused by other websites. For example, if you’re site is hosted on a shared server where there is another website that is being attacked or hogging up resources, this can affect the performance of your company’s site.

 

Flexibility & Customization

A dedicated server allows your business to customize the hardware and software based on your company’s unique needs. Things like CPU, Memory, Hard Drive, even the speed of the server’s network port, can all be customized and upgraded on dedicated servers. With shared hosting, you are limited to the software already installed on the server, and sometimes it may lack a requirement or feature your business needs. But with a dedicated server, you have full flexibility over which software the server runs, even down to the Operating System.

 

Administrative / Root Access

Another downside of shared hosting is the lack of Administrative or root access to the server. This limitation affects what software you can install as well as the settings and options that you can configure on the server. This can greatly impact the potential of what you are able to do with your website. Another advantage of administrative/root access is the ability to better monitor and troubleshoot your website, with full access to the server’s logs.

 

Dedicated IP Address

Each dedicated server comes with its own dedicated IP address. With shared hosting, your site may be sharing an IP address with multiple websites. If your website happens to share an IP with a site that spams or contains malware, this can cause multiple problems. Your website can end up getting blocked, your email rejected as spam, even your search results can be affected. Another thing to consider is whether or not you’ll be running an e-commerce or selling things on your site. If so, you will need to have an SSL for your site, which in turn requires a unique dedicated IP.

 

Now if you’re worried that you’re not tech savvy enough to run your own dedicated server, consider the option of going with a Managed Dedicated Server solution, which will provide many additional benefits on top of what’s listed above. Also if cost is a concern, check out our latest ‘Best Value’ Dedicated Servers. There are countless other advantages to using a dedicated server, however the 4 above are some of the most notable. So before you decide to host your website on a shared server, consider the added flexibility, reliability, and performance that only a dedicated server can provide.
