RAID in Cloud Hosting
The SSD drives which our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This type of RAID is intended to work with the ZFS file system that runs on the platform and it uses the so-called parity disk - a special drive where information kept on the other drives is cloned with an extra bit added to it. In case one of the disks stops working, your websites will continue working from the other ones and after we replace the problematic one, the info which will be copied on it will be recovered from what is stored on the remaining drives as well as the information from the parity disk. This is performed so as to be able to recalculate the elements of each file correctly and to verify the integrity of the information duplicated on the new drive. This is another level of security for the content you upload to your cloud hosting account together with the ZFS file system that compares a special digital fingerprint for every single file on all of the drives in real time.
