Redundant Array of Independent Disks, or RAID, is a method of keeping content on several hard disk drives simultaneously. A RAID can be software or hardware depending on the hard drives that are used - physical or logical ones, still 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 since the information on all drives is identical all of the time, so even in the event that a drive fails for some reason, the data will still be available on the other drives. The overall performance is also better since the reading and writing processes will be split between different drives, so a single one will not be overloaded. There are different types of RAIDs where the performance and fault tolerance may differ according to the particular setup - whether info is written on all the drives real-time or it is written on a single drive and afterwards mirrored on another, what amount of drives are used for the RAID, etc.

RAID in Shared Hosting

The revolutionary cloud Internet hosting platform where all shared hosting accounts are generated employs quick NVMe drives as an alternative to the classic HDDs, and they operate in RAID-Z. With this setup, a number of hard drives operate together and at least one of them is a dedicated parity disk. Basically, when data is written on the remaining drives, it's duplicated on the parity one adding an extra bit. This is done for redundancy as even in case some drive fails or falls out of the RAID for whatever reason, the info can be rebuilt and verified thanks to the parity disk and the data saved on the other ones, therefore practically nothing will be lost and there will be no service disorders. This is another level of security for your info together with the cutting-edge ZFS file system which uses checksums to guarantee that all data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Hosting

In case you host your Internet sites within a semi-dedicated hosting account from our firm, any content which you upload will be kept on NVMe drives which operate in RAID-Z. With this form of RAID, at least 1 of the hard disks is used 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 guarantee the integrity of the info which is duplicated to a brand new drive if one of the hard drives in the RAID stops working because the content being copied on the brand new disk is recalculated from the info on the standard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a drive stops functioning, the system can easily switch to another one right away without service disturbances of any sort. RAID-Z adds one more level of protection for the content you upload on our cloud web hosting platform along with the ZFS file system which uses unique checksums in order to validate the integrity of every single file.

RAID in VPS Web Hosting

All virtual private server accounts that we offer are made on physical servers which use NVMe drives operating in RAID. At least one drive is employed for parity - one extra bit is included in the data copied on it and if a main disk breaks down, this bit makes it much simpler to recalculate the bits of the files on the damaged hard disk so that the correct info is recovered 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 regular backups to your VPS plan, a copy of your information will be kept on standard disk drives that also operate in RAID since we would like to make sure that any sort of website content you add will be risk-free all of the time. Working with multiple drives in RAID for all the main and backup servers permits us to offer fast and reliable Internet hosting service.
