RAID in Shared Hosting
The SSD drives which our cutting-edge cloud hosting platform employs for storage function in RAID-Z. This sort of RAID is developed to work with the ZFS file system which runs on the platform and it uses the so-called parity disk - a specific drive where info kept on the other drives is duplicated with an additional bit added to it. In case one of the disks fails, your Internet sites will continue working from the other ones and once we replace the faulty one, the info which will be duplicated on it will be recovered from what is stored on the rest of the drives together with the data from the parity disk. This is done so as to be able to recalculate the bits of every file properly and to confirm the integrity of the info duplicated on the new drive. This is another level of security for the content you upload to your shared hosting account in addition to the ZFS file system that compares a unique digital fingerprint for every single file on all the hard drives in real time.
RAID in VPS Servers
If you use one of our VPS server solutions, any content which you upload will be saved on SSD drives which function in RAID. At least 1 drive is used for parity so as to ensure the integrity of the data. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk in the RAID stops functioning, your sites will continue working and when a new disk substitutes the defective one, the bits of the data that will be duplicated on it are calculated using the healthy and the parity drives. That way, any chance of corrupting data throughout the process is prevented. We also use conventional hard disk drives that work in RAID for storing backup copies, so should you include this service to your VPS plan, your content will be saved on multiple drives and you will never have to worry about its integrity even in the event of multiple drive breakdowns.
