RAID in Shared Hosting
The SSD drives which our cutting-edge cloud hosting platform employs for storage work in RAID-Z. This type of RAID is developed to work with the ZFS file system that runs on the platform and it employs the so-called parity disk - a specific drive where info saved 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 as soon as we replace the faulty one, the data that will be cloned on it will be rebuilt from what is stored on the rest of the drives along with the data from the parity disk. This is done so as to be able to recalculate the bits of every single file correctly and to authenticate the integrity of the information duplicated on the new drive. This is another level of security for the information that you upload to your shared hosting account together with the ZFS file system that compares a special digital fingerprint for each file on all disk drives in real time.
RAID in Semi-dedicated Servers
If you host your websites inside a semi-dedicated server account from our firm, all of the content which you upload will be held on SSD drives that work in RAID-Z. With this kind of RAID, at least one of the hard disks is employed for parity - when data is synced between the drives, an additional bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the data which is copied to a brand new drive in the event that one of the hard drives in the RAID stops working as the website content being copied on the brand new disk is recalculated from the information on the standard disk drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a disk drive stops working, the system could switch to another one quickly without service interruptions of any kind. RAID-Z adds an extra level of security for the content which you upload on our cloud web hosting platform in addition to the ZFS file system that uses unique checksums so as to verify the integrity of each file.
RAID in VPS Servers
If you use one of our VPS server packages, any content that you upload will be kept on SSD drives that function in RAID. At least one drive is employed for parity so as to guarantee the integrity of the information. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk inside the RAID fails, your websites will continue working and when a new disk substitutes the malfunctioning one, the bits of the data that will be cloned on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is prevented. We also use ordinary hard drives that work in RAID for storing backup copies, so if you include this service to your VPS package, your site content will be saved on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive breakdowns.
