RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function in RAID-Z. This kind of RAID is designed to work with the ZFS file system which runs on the platform and it uses the so-called parity disk - a special drive where data stored on the other drives is copied with an extra bit added to it. In case one of the disks stops functioning, your Internet sites will continue working from the other ones and once we replace the malfunctioning one, the information which will be cloned on it will be rebuilt from what is stored on the other drives along with the information from the parity disk. This is done so as to be able to recalculate the elements of every file properly and to authenticate the integrity of the data cloned on the new drive. This is one more level of security for the information which you upload to your cloud hosting account together with the ZFS file system that analyzes a special digital fingerprint for every single file on all the hard drives in real time.
RAID in Semi-dedicated Servers
The SSD drives that are used for holding any site content uploaded to the semi-dedicated server accounts which we provide function in RAID-Z. This is a special setup where one or more drives are used for parity i.e. the system will add an extra bit to any data copied on this type of a drive. If a disk fails and is replaced with a new one, what information will be copied on the latter shall be a combination calculated between the data on the remaining drives and that on the parity one. This is done to make sure that the data on the new drive will be correct. During the procedure, the RAID will continue working normally and the faulty drive will not impact the adequate operation of your sites at all. Using SSDs in RAID-Z is an amazing addition to the ZFS file system that runs on our cutting-edge cloud platform in terms of preserving the integrity of your files since ZFS uses specific digital identifiers known as checksums in order to avoid silent data corruption.
