RAID in Shared Web Hosting
The SSD drives which our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This kind of RAID is developed 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 data kept on the other drives is duplicated with an additional bit added to it. In the event that one of the disks stops working, your sites will continue working from the other ones and once we replace the problematic one, the info that will be cloned on it will be recovered from what is stored on the other drives as well as the data from the parity disk. This is performed in order to be able to recalculate the bits of each and every file properly and to authenticate the integrity of the information cloned on the new drive. This is one more level of security for the information that you upload to your shared web hosting account along with the ZFS file system that compares a unique digital fingerprint for each file on all drives in real time.
RAID in Semi-dedicated Servers
If you host your Internet sites in a semi-dedicated server account from our firm, all the content you upload will be held on SSD drives which work in RAID-Z. With this type of RAID, at least 1 of the hard drives is employed for parity - when data is synced between the drives, an extra bit is included in it on the parity one. The reasoning behind this is to guarantee the integrity of the info which is duplicated to a brand new drive in case one of the hard drives in the RAID stops functioning because the site content being copied on the brand new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a disk drive fails, the system can switch to another one quickly without service disruptions of any type. RAID-Z adds one more level of protection for the content which you upload on our cloud Internet hosting platform in addition to the ZFS file system that uses unique checksums so as to validate the integrity of each and every file.
