RAID in Shared Website Hosting
The SSD drives which our cutting-edge cloud hosting platform employs for storage operate in RAID-Z. This kind of RAID is created 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 located on the other drives is copied with an extra bit added to it. If one of the disks stops functioning, your Internet sites will continue working from the other ones and as soon as we replace the malfunctioning one, the info that will be copied on it will be rebuilt from what is stored on the rest of the drives as well as the info from the parity disk. This is done so as to be able to recalculate the elements of each and every file properly and to verify the integrity of the info duplicated on the new drive. This is another level of security for the content that you upload to your shared website hosting account together with the ZFS file system which compares a special digital fingerprint for every single file on all disk drives in real time.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud hosting platform where your semi-dedicated hosting account shall be created is referred to as RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. Put simply, whenever any data is copied on this special disk drive, one more bit is included to it and if a problematic disk is replaced, the information that will be cloned on it is a combination of the data on the remaining hard drives in the RAID and that on the parity one. This is done to make sure that your data is intact. Throughout this process, your Internet sites will be functioning normally because RAID-Z allows for a whole drive to fail without service disruptions and it simply uses one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to ensure that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS Web Hosting
If you take advantage of one of our virtual private server solutions, any content that you upload will be stored on SSD drives that work in RAID. At least one drive is employed for parity to guarantee the integrity of your data. In simple terms, this is a special drive where info is copied with one bit added to it. If a disk inside the RAID fails, your websites will continue working and when a new disk takes the place of the defective one, the bits of the info that will be duplicated on it are calculated using the healthy and the parity drives. By doing this, any chance of corrupting data during the process is averted. We also employ conventional hard disk drives that work in RAID for storing backup copies, so should you add this service to your VPS package, your website content will be stored on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive failures.
