RAID in Cloud Website Hosting
The SSD drives that our cutting-edge cloud web hosting platform uses for storage function in RAID-Z. This sort of RAID is created to work with the ZFS file system which runs on the platform and it employs the so-called parity disk - a specific drive where information stored on the other drives is cloned with an additional bit added to it. If one of the disks fails, your Internet sites will continue working from the other ones and as soon as we replace the bad one, the data which will be cloned on it will be rebuilt from what is stored on the remaining drives as well as the information from the parity disk. This is performed in order to be able to recalculate the bits of every single file properly and to authenticate the integrity of the info cloned on the new drive. This is an additional level of security for the content you upload to your cloud website hosting account along with the ZFS file system that analyzes a special digital fingerprint for each file on all hard drives in real time.
RAID in Semi-dedicated Servers
In case you host your websites inside a semi-dedicated server account from our firm, all of the content you upload will be saved on SSD drives that work in RAID-Z. With this type of RAID, at least 1 of the drives is used for parity - when data is synchronized between the hard drives, an additional bit is added to it on the parity one. The idea behind this is to guarantee the integrity of the information which is duplicated to a brand new drive if one of the disks in the RAID fails as the content being copied on the new disk is recalculated from the data on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even if a disk drive stops functioning, the system could switch to another one promptly without service interruptions of any sort. RAID-Z adds one more level of protection for the content which you upload on our cloud web hosting platform together with the ZFS file system that uses unique checksums as a way to verify the integrity of each file.
