RAID, or Redundant Array of Independent Disks, is a technology of saving data on a number hard disks which operate together as one logical unit. The drives could be physical or logical i.e. in the aforementioned case one single drive is divided into independent ones through virtualization software. In either case, identical data is saved on all drives and the main advantage of using this kind of a setup is that in case a drive stops working, the data shall still be available on the remaining ones. Having a RAID also boosts the overall performance because the input and output operations will be spread among a few drives. There are several kinds of RAID dependant upon how many drives are used, whether writing is done on all of the drives in real time or just on a single one, and how the data is synchronized between the hard drives - whether it's recorded in blocks on one drive after another or it is mirrored from one on the others. These factors show that the error tolerance and the performance between the various RAID types can vary.

RAID in Website Hosting

The SSD drives which our cutting-edge cloud hosting platform uses for storage work in RAID-Z. This sort of RAID is designed to work with the ZFS file system that runs on the platform and it employs the so-called parity disk - a special drive where info stored on the other drives is copied with an additional bit added to it. In the event that one of the disks fails, your Internet sites will continue working from the other ones and as soon as we replace the bad one, the data which will be cloned on it will be rebuilt from what is stored on the rest of the drives together with the info from the parity disk. This is done in order to be able to recalculate the elements of every single file adequately and to verify the integrity of the info copied on the new drive. This is an additional level of security for the content you upload to your website hosting account together with the ZFS file system that analyzes a special digital fingerprint for every single file on all hard drives in real time.

RAID in Semi-dedicated Servers

If you host your sites within a semi-dedicated server account from our company, any content which you upload will be held on SSD drives that work in RAID-Z. With this kind of RAID, at least 1 of the disks is used for parity - when data is synced between the disks, an extra bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the info that is copied to a new drive if one of the drives in the RAID breaks down since the content being copied on the new disk is recalculated from the info on the standard drives and on the parity one. Another advantage of RAID-Z is that even if a drive stops working, the system can easily switch to another one right away without service interruptions of any type. RAID-Z adds an additional level of protection for the content you upload on our cloud web hosting platform together with the ZFS file system that uses unique checksums as a way to authenticate the integrity of each and every file.

RAID in VPS Servers

All VPS server accounts which we provide are made on physical servers that employ SSD drives working in RAID. At least one drive is intended for parity - one additional bit is added to the information cloned on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged drive so that the right info is restored on the new drive added to the RAID. In the mean time, your Internet sites will still be online since all the data will still load from at least one more drive. In the event that you add routine backups to your VPS package, a copy of the information will be stored on standard hard disks which also work in RAID as we would like to make certain that any website content you add will be protected all the time. Employing multiple hard drives in RAID for all main and backup servers enables us to offer fast and reliable web hosting service.
