RAID in Cloud Web Hosting
The SSD drives which our cutting-edge cloud hosting platform employs for storage operate in RAID-Z. This type of RAID is created to work with the ZFS file system which runs on the platform and it works by using the so-called parity disk - a specific drive where info located on the other drives is copied with an additional bit added to it. If one of the disks fails, your websites shall continue working from the other ones and as soon as we replace the faulty one, the information which will be cloned on it will be rebuilt from what is stored on the rest of the drives as well as the information from the parity disk. This is done in order to be able to recalculate the bits of each and every file correctly and to verify the integrity of the information cloned on the new drive. This is an additional level of security for the information that you upload to your cloud web hosting account together with the ZFS file system which compares a special digital fingerprint for each file on all of the drives in real time.
RAID in Semi-dedicated Hosting
In case you host your Internet sites inside a semi-dedicated hosting account from our company, 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 used for parity - when data is synced between the disks, an extra bit is included in it on the parity one. The purpose behind this is to guarantee the integrity of the information which is cloned to a brand new drive in the event that one of the hard drives in the RAID fails because the content being copied on the brand new disk is recalculated from the data on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even in case a drive fails, the system could switch to another one promptly without service disturbances of any kind. RAID-Z adds an extra level of safety for the content that you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums to verify the integrity of each and every file.
