RAID, or Redundant Array of Independent Disks, is a technology of storing data on a number hard disks which work together as a single logical unit. The drives could be physical or logical i.e. in the latter case one drive is split into individual ones through virtualization software. In any case, exactly the same information is saved on all of the drives and the key benefit of using such a setup is that if a drive stops working, the data shall still be available on the remaining ones. Employing a RAID also improves the performance as the input and output operations will be spread among a number of drives. There are several kinds of RAID dependant upon how many hard drives are used, whether writing is performed on all the drives in real time or just on a single one, and how the information is synchronized between the drives - whether it's recorded in blocks on one drive after another or all of it is mirrored from one on the others. These factors mean that the fault tolerance and the performance between the various RAID types could differ.

RAID in Shared Hosting

The disk drives which we use for storage with our revolutionary cloud Internet hosting platform are not the classic HDDs, but quick NVMes. They work in RAID-Z - a special setup intended for the ZFS file system which we employ. Any content that you add to the shared hosting account will be stored on multiple drives and at least 1 shall be employed as a parity disk. This is a specific drive where an extra bit is included to any content copied on it. In case a disk in the RAID fails, it'll be replaced without service disturbances and the data will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the remaining disks. This is done to guarantee the integrity of the info and along with the real-time checksum verification that the ZFS file system executes on all drives, you'll never have to be concerned about the loss of any data no matter what.

RAID in Semi-dedicated Hosting

If you host your websites inside a semi-dedicated hosting account from our firm, all the content that you upload will be held on NVMe drives that work in RAID-Z. With this form of RAID, at least 1 of the drives is used for parity - when data is synced between the disks, an extra bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the data which is duplicated to a new drive in the event that one of the hard drives in the RAID stops working as the content being copied on the brand new disk is recalculated from the info on the standard disk drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a drive stops working, the system could switch to another one promptly without service disturbances of any sort. RAID-Z adds an additional level of protection for the content you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums in order to verify the integrity of each file.

RAID in VPS Web Hosting

The physical servers where we make virtual private server employ high-speed NVMe drives that will boost the speed of your Internet sites significantly. The disk drives function in RAID to make sure that you will not lose any data as a result of a power loss or a hardware breakdown. The production servers employ a variety of drives where the data is saved and one disk is used for parity i.e. one bit is added to all of the information copied on it, which makes it much easier to recover the website content without any loss if a main drive stops working. If you pick our backup service, your info will be saved on an independent machine which uses standard hard-disk drives and although there is no parity one in this case, they are also in a RAID to ensure that we will have a backup copy of your site content all of the time. With this kind of configuration your data will always be safe because it will be available on a lot of drives.
