Redundant Array of Independent Disks, or RAID, is a method of storing content on a number of hard drives at the same time. A RAID could be software or hardware depending on the HDDs that are used - physical or logical ones, yet what’s common between them is the fact that they all operate as a single unit where information is saved. The key advantage of using a RAID is redundancy as the info on all the drives will be exactly the same all the time, so even in case some drive fails for whatever reason, the info will still be available on the rest of the drives. The overall performance is also enhanced as the reading and writing processes will be split between different drives, so a single one won't be overloaded. There're different types of RAIDs where the efficiency and fault tolerance can vary according to the particular setup - whether your data is written on all the drives in real time or it is written on a single drive and after that mirrored on another, what amount of drives are used for the RAID, and so on.

RAID in Cloud Hosting

The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function in RAID-Z. This type of RAID is designed to work with the ZFS file system that runs on the platform and it works by using the so-called parity disk - a specific drive where info located on the other drives is cloned with an extra bit added to it. In the event that one of the disks stops functioning, your Internet sites will continue working from the other ones and once we replace the faulty one, the information that will be duplicated on it will be rebuilt from what is stored on the other drives along with the data from the parity disk. This is done so as to be able to recalculate the elements of each file properly and to validate the integrity of the information duplicated on the new drive. This is one more level of security for the information that you upload to your cloud hosting account in addition to the ZFS file system that compares a special digital fingerprint for each and every file on all hard drives in real time.

RAID in Semi-dedicated Hosting

In case you host your websites inside a semi-dedicated hosting account from our company, any content which you upload will be saved on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the disks is used for parity - when data is synchronized between the drives, an additional bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the information which is cloned to a brand new drive in case one of the disks in the RAID fails as the site content being copied on the new disk is recalculated from the data on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even if a disk drive fails, the system can easily switch to another one promptly without service interruptions of any sort. RAID-Z adds one more level of security for the content that you upload on our cloud Internet hosting platform along with the ZFS file system which uses unique checksums in order to validate the integrity of each and every file.

RAID in VPS Hosting

In case you employ one of our virtual private server solutions, any content you upload will be stored on SSD drives which operate in RAID. At least 1 drive is employed for parity to ensure the integrity of your information. In simple terms, this is a special drive where information is copied with one bit added to it. In the event that a disk within the RAID fails, your sites will continue working and when a new disk substitutes the flawed one, the bits of the info that will be cloned on it are calculated by using the healthy and the parity drives. This way, any potential for corrupting data during the process is averted. We also employ standard hard disk drives that work in RAID for storing backups, so if you include this service to your VPS plan, your site content will be saved on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive breakdowns.
