RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which enables a system to take advantage of several hard drives as one single logical unit. Simply put, all the drives are used as one and the information on all of them is the same. This kind of a setup has two huge advantages over using a single drive to store data - the first is redundancy, so in case one drive stops working, the data will be accessible through the remaining ones, and the second one is improved performance since the input/output, or reading/writing operations will be spread among several drives. There are different RAID types based on what number of drives are employed, if reading and writing are both done from all the drives concurrently, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, etc. Based on the particular setup, the error tolerance and the performance may vary.

RAID in Cloud Website Hosting

All of the content which you upload to your new cloud website hosting account will be placed on quick SSD drives which work in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud hosting platform and it adds an additional level of protection for your site content on top of the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is stored on a couple of disks and at least 1 is a parity disk - whenever information is written on it, an additional bit is added, so if any drive stops working for whatever reason, the stability of the info can be verified by recalculating its bits based on what is kept on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating effectively until the malfunctioning drive is replaced and the data is synced on it.

RAID in Semi-dedicated Servers

If you host your sites within a semi-dedicated server account from our company, all of the content that you upload will be saved on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the drives is used for parity - when data is synced between the drives, an additional bit is added to it on the parity one. The purpose behind this is to guarantee the integrity of the information that is copied to a brand new drive in case one of the drives in the RAID breaks down since the site content being copied on the brand new disk is recalculated from the info on the standard disk drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a hard drive stops functioning, the system can easily switch to a different one promptly without service disruptions of any type. RAID-Z adds an additional level of security for the content that you upload on our cloud web hosting platform together with the ZFS file system that uses unique checksums as a way to verify the integrity of each file.

RAID in VPS Servers

In case you take advantage of one of our VPS server packages, any content that you upload will be stored on SSD drives that function in RAID. At least a single drive is employed for parity to ensure the integrity of your info. In simple terms, this is a special drive where information is copied with one bit added to it. In case a disk part of the RAID breaks down, your websites will continue working and when a new disk takes the place of the malfunctioning one, the bits of the data that will be copied on it are calculated using the healthy and the parity drives. This way, any potential for corrupting data throughout the process is prevented. We also use regular hard disks that work in RAID for storing backup copies, so in case you include this service to your VPS plan, your content will be kept on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive breakdowns.
