RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that enables a system to take advantage of many hard drives as a single logical unit. Simply put, all drives are used as one and the data on all of them is the same. This kind of a configuration has 2 key advantages over using just a single drive to save data - the first is redundancy, so in the event that one drive breaks down, the data will be accessible from the remaining ones, and the second is better performance because the input/output, or reading/writing operations will be spread among different drives. There are different RAID types based on what amount of drives are employed, whether reading and writing are both executed from all drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Determined by the particular setup, the fault tolerance and the performance could differ.

RAID in Cloud Hosting

The revolutionary cloud Internet hosting platform where all cloud hosting accounts are created employs fast NVMe drives rather than the classic HDDs, and they function in RAID-Z. With this configuration, a number of hard disks function together and at least one is a dedicated parity disk. Simply put, when data is written on the remaining drives, it is cloned on the parity one adding an extra bit. This is done for redundancy as even if some drive fails or falls out of the RAID for some reason, the information can be rebuilt and verified thanks to the parity disk and the data saved on the other ones, so practically nothing will be lost and there will not be any service disturbances. This is one more level of protection for your data together with 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 Servers

The NVMe drives that are used for holding any website content uploaded to the semi-dedicated server accounts which we offer operate in RAID-Z. This is a special configuration where one or more drives are used for parity i.e. the system will add an extra bit to any data cloned on this type of a hard drive. If a disk fails and is substituted with a new one, what information will be duplicated on the latter shall be a combination calculated between the data on the remaining hard disks and that on the parity one. This is done to guarantee that the information on the new drive shall be correct. During the procedure, the RAID will continue working adequately and the faulty drive will not have an effect on the adequate operation of your websites in any way. Using NVMes in RAID-Z is an impressive addition to the ZFS file system which runs on our top-notch cloud platform with respect to preserving the integrity of your files as ZFS uses specific digital identifiers referred to as checksums in order to prevent silent data corruption.

RAID in VPS Servers

The physical servers where we make VPS server work with fast NVMe drives which will raise the speed of your sites noticeably. The hard disks work in RAID to make sure that you will not lose any information because of a power loss or a hardware breakdown. The production servers take advantage of many different drives where the information is kept and one disk is used for parity i.e. one bit is added to all of the information copied on it, which makes it easier to restore the website content without any loss if a main drive breaks down. If you take advantage of our backup service, your data will be kept on an independent machine which uses standard hard-disk drives and though there isn't a parity one in this case, they are also in a RAID to ensure that we will have a backup copy of your site content at all times. With this type of configuration your data will always be safe because it will be available on a lot of drives.
