RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that makes it possible for a system to use a number of hard drives as one single logical unit. Put simply, all drives are used as one and the data on all of them is the same. This kind of a setup has 2 key advantages over using just a single drive to keep data - the first one is redundancy, so if one drive fails, the data will be accessed from the remaining ones, and the second is better performance since the input/output, or reading/writing operations will be spread among multiple drives. There are different RAID types depending on how many drives are used, if reading and writing are both handled from all of the drives concurrently, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Determined by the exact setup, the error tolerance and the performance may differ.

RAID in Cloud Website Hosting

All of the content that you upload to your new cloud website hosting account will be stored on quick SSD drives which operate in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud hosting platform and it adds one more level of protection for your website content in addition to the real-time checksum authentication that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is saved on several disks and at least one is a parity disk - whenever info is recorded on it, an additional bit is added, so if any drive stops functioning for some reason, the integrity of the info can be verified by recalculating its bits based on what is saved on the production hard drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue working efficiently until the problematic drive is replaced and the info is synced on it.

RAID in Semi-dedicated Hosting

In case you host your websites within a semi-dedicated hosting account from our firm, all of the content that you upload will be kept on SSD drives which operate in RAID-Z. With this form of RAID, at least one of the hard drives is employed for parity - when data is synced between the hard drives, an additional bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the data that is cloned to a new drive if one of the hard drives in the RAID stops functioning as the site content being copied on the new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is that even if a drive fails, the system could switch to a different one instantly without service interruptions of any sort. RAID-Z adds one more level of security for the content that you upload on our cloud hosting platform together with the ZFS file system that uses unique checksums so as to authenticate the integrity of each and every file.

RAID in VPS

All virtual private server accounts that we provide are generated on physical servers which employ SSD drives functioning in RAID. At least 1 drive is used for parity - one extra bit is included in the info copied on it and if a main disk breaks down, this bit makes it much easier to recalculate the bits of the files on the damaged hard disk so that the right info is restored on the new drive added to the RAID. Meanwhile, your websites will remain online because all the data will still load from at least one more hard drive. In case you add routine backups to your VPS plan, a copy of the info will be saved on standard disk drives which also function in RAID because we would like to make certain that any sort of content you add will be protected all of the time. Employing multiple hard disks in RAID for all main and backup servers allows us to offer fast and reliable hosting service.
