Redundant Array of Independent Disks, or RAID, is a method of storing content on several hard disks at the same time. A RAID can be software or hardware based on the drives which are used - physical or logical ones, yet what is common between them is that they all work as one single unit where your information is saved. The main advantage of employing a RAID is redundancy as the information on all of the drives will be identical all of the time, so even if some drive fails for some reason, the info will still be present on the remaining drives. The overall performance is enhanced as well since the reading and writing processes could be split between various drives, so a single one won't be overloaded. There're different kinds of RAIDs where the performance and fault tolerance could differ according to the particular setup - whether information is written on all drives real-time or it is written on a single drive and afterwards mirrored on another, what number of drives are used for the RAID, etc.

RAID in Shared Web Hosting

The cutting-edge cloud Internet hosting platform where all shared web hosting accounts are generated uses quick SSD drives instead of the standard HDDs, and they operate in RAID-Z. With this setup, numerous hard disks operate together and at least a single one is a dedicated parity disk. Put simply, when data is written on the other drives, it's duplicated on the parity one adding an extra bit. This is performed for redundancy as even in case a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, therefore practically nothing will be lost and there won't be any service disorders. This is another level of protection for your info in addition to the cutting-edge ZFS file system which uses checksums to ensure that all of the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The info uploaded to any semi-dedicated hosting account is saved on SSD drives which work in RAID-Z. One of the drives in type of a setup is used for parity - any time data is copied on it, an additional bit is added. In case a disk happens to be flawed, it will be taken out of the RAID without interrupting the functioning of the Internet sites since the data will load from the rest of the drives, and when a new drive is included, the information that will be duplicated on it will be a blend between the information on the parity disk and data saved on the other hard disks in the RAID. That is done to guarantee that the info which is being duplicated is accurate, so once the new drive is rebuilt, it could be integrated into the RAID as a production one. This is one more warranty for the integrity of your info because the ZFS file system that runs on our cloud hosting platform analyzes a special checksum of all of the copies of your files on the different drives in order to avoid any probability of silent data corruption.

RAID in VPS Web Hosting

All virtual private server accounts which we provide are made on physical servers that use SSD drives working in RAID. At least 1 drive is used for parity - one additional bit is added to the information duplicated on it and in case a main disk fails, this bit makes it much simpler to recalculate the bits of the files on the failed drive so that the correct information is recovered on the new drive included in the RAID. Meanwhile, your Internet sites will remain online as all the info will still load from at least one more disk drive. In the event that you add regular backups to your VPS package, a copy of your data will be stored on standard hard disks that also operate in RAID as we would like to make certain that any kind of site content you add will be protected all of the time. Employing multiple drives in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
