RAID
See the pros of having your web sites and apps hosted on a RAID-enabled hosting server.
RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to use many hard drives as one single logical unit. Put simply, all of the drives are used as one and the information on all of them is identical. This kind of a setup has 2 key advantages over using a single drive to save data - the first is redundancy, so in the event that one drive fails, the info will be accessible from the remaining ones, and the second one is improved performance as the input/output, or reading/writing operations will be distributed among a number of drives. You can find different RAID types in accordance with what amount of drives are employed, whether reading and writing are both executed from all of the drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Determined by the exact setup, the error tolerance and the performance may differ.

RAID in Shared Hosting
All the content that you upload to your new
shared hosting account will be stored on fast NVMe drives that operate in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of security for your content in addition to the real-time checksum verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a couple of disks and at least one is a parity disk - whenever info is recorded on it, an additional bit is added, so in case any drive stops functioning for whatever reason, the stability of the information can be verified by recalculating its bits in accordance with what is kept on the production disks and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue operating smoothly until the faulty drive is changed and the info is synced on it.

RAID in Semi-dedicated Servers
In case you host your websites within a
semi-dedicated server account from our firm, all the content that you upload will be kept on NVMe drives which operate in RAID-Z. With this form of RAID, at least one of the disks is employed for parity - when data is synchronized between the hard drives, an extra bit is included in it on the parity one. The reasoning behind this is to guarantee the integrity of the data that is duplicated to a brand new drive in the event that one of the drives in the RAID breaks down as the content being copied on the brand new disk is recalculated from the data on the standard disk drives and on the parity one. An additional advantage of RAID-Z is that even in the event that a drive fails, the system can easily switch to another one immediately without service disturbances of any sort. RAID-Z adds an extra level of protection for the content which you upload on our cloud hosting platform together with the ZFS file system which uses unique checksums to verify the integrity of each file.
