RAID in Web Hosting
The NVMe drives which our cutting-edge cloud hosting platform uses for storage work in RAID-Z. This kind of RAID is designed to work with the ZFS file system that runs on the platform and it takes advantage of the so-called parity disk - a special drive where info kept on the other drives is cloned with an extra bit added to it. In the event that one of the disks stops functioning, your Internet sites shall continue working from the other ones and once we replace the bad one, the info which will be duplicated on it will be rebuilt from what is stored on the other drives as well as the info from the parity disk. This is performed in order to be able to recalculate the bits of every file correctly and to validate the integrity of the data duplicated on the new drive. This is an additional level of security for the info which you upload to your web hosting account together with the ZFS file system which compares a unique digital fingerprint for each file on all the disk drives in real time.
RAID in Semi-dedicated Servers
In case you host your Internet sites within a semi-dedicated server account from our firm, all the content that you upload will be stored on NVMe drives which operate in RAID-Z. With this form of RAID, at least one of the drives is employed 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 that is copied to a new drive in the event that one of the disks in the RAID stops functioning as the website content being copied on the brand new disk is recalculated from the information on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even if a hard drive stops working, the system can easily switch to a different one immediately without service interruptions of any type. RAID-Z adds an extra level of protection for the content you upload on our cloud Internet hosting platform in addition to the ZFS file system which uses unique checksums as a way to authenticate the integrity of every single file.
RAID in VPS Servers
The physical servers where we generate VPS server work with extremely fast NVMe drives that will boost the speed of your websites significantly. The disk drives operate in RAID to guarantee that you will not lose any info due to a power loss or a hardware failure. The production servers work with a variety of drives where the info is stored and one disk is used for parity i.e. one bit is added to all the info copied on it, that makes it easier to restore the content without any loss in case a main drive stops working. In case you use our backup service, your data will be kept on an independent machine that 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 the time. With this kind of configuration your information will always be safe since it will be available on multiple drives.
