Redundant Array of Independent Disks, or RAID, is a way of storing content on multiple hard disk drives at the same time. A RAID might be software or hardware based on the hard drives which are used - physical or logical ones, but what is common between them is that they all function as one single unit where info is stored. The key advantage of using a RAID is redundancy as the info on all drives shall be identical at all times, so even if a drive fails for whatever reason, the information will still be available on the remaining drives. The overall performance will also improve since the reading and writing processes could be split between different drives, so a single one will never be overloaded. There're different sorts of RAIDs where the performance and fault tolerance could differ according to the exact setup - whether info is written on all the drives real-time or it is written on one drive and after that mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Hosting

The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function in RAID-Z. This kind of RAID is intended to work with the ZFS file system which runs on the platform and it uses the so-called parity disk - a specific drive where info saved on the other drives is copied with an additional bit added to it. In the event that one of the disks stops functioning, your Internet sites shall continue working from the other ones and after we replace the faulty one, the information which will be copied on it will be rebuilt from what is stored on the other drives along with the info from the parity disk. This is performed in order to be able to recalculate the elements of every single file adequately and to confirm the integrity of the info cloned on the new drive. This is another level of security for the information which you upload to your hosting account along with the ZFS file system which compares a unique digital fingerprint for each and every file on all the disk drives in real time.

RAID in Semi-dedicated Hosting

If you host your Internet sites within a semi-dedicated hosting account from our firm, all of the content that you upload will be saved on SSD drives which operate in RAID-Z. With this kind of RAID, at least one of the disks is employed for parity - when data is synced between the hard drives, an additional bit is included in it on the parity one. The purpose behind this is to ensure the integrity of the information that is cloned to a new drive in the event that one of the hard drives in the RAID stops working as the website content being copied on the new disk is recalculated from the information on the standard drives and on the parity one. An additional advantage of RAID-Z is the fact that even if a hard drive stops functioning, the system can easily switch to another one quickly without service interruptions of any sort. RAID-Z adds an additional level of protection for the content which you upload on our cloud hosting platform along with the ZFS file system that uses unique checksums as a way to validate the integrity of every single file.

RAID in VPS Hosting

All virtual private server accounts that our company provides are made on physical servers that employ SSD drives working in RAID. At least one drive is intended for parity - one additional bit is included in the data duplicated on it and if a main disk stops working, this bit makes it easier to recalculate the bits of the files on the damaged disk drive so that the accurate info is restored on the new drive included in the RAID. At the same time, your sites will stay online since all the data will still load from at least one other drive. In case you add routine backups to your VPS plan, a copy of your data will be saved on standard hard disks that also function in RAID as we want to make certain that any sort of website content you upload will be safe and sound all the time. Employing multiple drives in RAID for all main and backup servers allows us to offer fast and reliable hosting service.
