For many clients just starting out with a website or a new business, a Shared Hosting solution or Virtual Private Server (VPS) is often enough to get off the ground. But, for many there comes a point when these solutions just aren’t enough.

The most obvious sign that it’s time for an upgrade is when your website has started regularly requiring more bandwidth or power than your current plan provides. Sure, this is kind of a no-brainer, but it’s a good idea to upgrade before you start running into trouble. If your site starts topping out the charts, it could temporarily go offline and that’s not good for business. Often we will see clients’ websites explode all of a sudden because they ran a special promotion or got some good press, and we will always work with them to make the transition to a dedicated server as seamless as possible. But, if you start seeing things getting busy, you can avoid a stressful situation with a preventative upgrade.

Another time an upgrade is a good idea is when a web application transitions out of beta or the development stage. While you’re working the bugs out of your application, a VPS can work fine. With just a few developers and beta testers in the system, a dedicated server would probably be overkill anyway. Once you release your application to the public, however, you’ll want to make sure you plan for the inevitable boom in traffic. Nobody wants their newly released project going down right out of the gate!

Regardless of the content of your website, if you’re worried about stability, dedicated servers are always the safest bet. Below you will find a summary of all the benefits a dedicated server provides (and how TurnKey Internet maximizes those benefits for our customers):

• Speed and Performance: Server and network response times in a shared hosting environment depend highly on the activity of others 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 hosting environment, 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 database system: it’s all there when you need it. If a neighbor causes a problem by over using resources, it will not impact your website or your business.
• 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 (disk, CPU, RAM, etc.) and can configure customized security policies server-wide such as firewall protection, user-level permissions and even restrict the types of applications that run on the server. With other forms of hosting, such as shared hosting, the neighbors you share space with could jeopardize the security of your web and database systems.
• Customization and Flexibility: 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, Perl/CGI or custom database configurations to suit your application needs, providing substantial performance gains over any other form of hosting. You maintain full root ‘administrator’ access to the server and can install, remove, or modify any applications you wish. If you need even more power behind your hosted application, TurnKey can customize your server with additional RAM, disk and bandwidth to suit your needs or provide you with advanced enterprise level solutions such as clustering, virtualization, load balancing and mirroring of your dedicated server.
• Easy-To-Use-Software: TurnKey Internet offers easy-to-use, pre-installed and pre-configured hosting applications for your web, database and mail system needs. If you know how to use a web browser, you are ready to use a TurnKey Dedicated Server with your choice of control panel, such as cPanel or Plesk. You can even select your choice of Operating System, such as Linux or Windows.
• Multiple Domains: Dedicated servers provide a cost-effective and management-friendly solution to multiple domain hosting. Rather than dealing with the burden of numerous accounts on shared hosting servers, you can host a virtually unlimited number of domains on a single dedicated server. With our server management software, it’s easy to create, manage and delete accounts whenever you want, and all from one interface.
• Worry-Free Operation: TurnKey Internet provides Fully Managed Solutions to ensure you don’t have to worry about your server and can keep your focus on running your business. From offsite backups to managed Firewall and Security monitoring, TurnKey takes care of everything for you.

As you can see, dedicated servers are the best solution for those that are serious about their website or business 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, reselling hosting to others, have sensitive data contained in your site or simply want more speed, power and control, it’s time to upgrade to a dedicated server.

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.
