RAID in Hosting
The SSD drives which our cutting-edge cloud web hosting platform employs for storage work in RAID-Z. This kind 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 data saved on the other drives is cloned with an extra bit added to it. If one of the disks fails, your websites shall continue working from the other ones and once we replace the problematic one, the info which will be duplicated on it will be rebuilt from what is stored on the other drives as well as the data from the parity disk. This is performed so as to be able to recalculate the elements of every single file adequately and to validate the integrity of the information cloned on the new drive. This is one more level of security for the content that you upload to your hosting account along with the ZFS file system which compares a unique digital fingerprint for every single file on all hard drives in real time.
RAID in Semi-dedicated Hosting
The RAID type that we employ for the cloud web hosting platform where your semi-dedicated hosting account shall be created is known as RAID-Z. What is different about it is that at least 1 of the disks is employed as a parity drive. In simple terms, whenever any data is cloned on this particular hard drive, one more bit is added to it and if a malfunctioning disk is replaced, the data which will be duplicated on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. It's done this way to make sure that your info is intact. During this process, your Internet sites will be up and running normally because RAID-Z enables a whole drive to fail without service interruptions and it simply works by using one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to warrant that no data will get silently corrupted on our servers, you will never have to worry about the integrity of your files.
