RAID
Discover the benefits of having your websites and applications hosted on a RAID-enabled server.
RAID, which is an acronym of Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that permits a system to take advantage of a number of hard drives as one single logical unit. To put it differently, all the drives are used as one and the data on all of them is the same. This type of a setup has two huge advantages over using just a single drive to store data - the first is redundancy, so in the event that one drive fails, the info will be accessed through the remaining ones, and the second is better performance as the input/output, or reading/writing operations will be distributed among several drives. There are different RAID types depending on the number of drives are employed, if reading and writing are both handled from all of the drives simultaneously, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Based on the particular setup, the fault tolerance and the performance could differ.
RAID in Hosting
The advanced cloud web hosting platform where all hosting accounts are created employs fast NVMe drives instead of the traditional HDDs, and they work in RAID-Z. With this setup, a number of hard disks work together and at least 1 is a dedicated parity disk. In simple terms, when data is written on the other drives, it's copied on the parity one adding an extra bit. This is performed for redundancy as even in case some drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, thus absolutely nothing will be lost and there will be no service disturbances. This is another level of protection for your information in addition to the revolutionary ZFS file system that uses checksums to guarantee that all the data on our servers is intact and is not silently corrupted.
