RAID in Cloud Web Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform employs for storage operate in RAID-Z. This kind of RAID is developed to work with the ZFS file system which runs on the platform and it takes advantage of the so-called parity disk - a specific drive where data located on the other drives is copied with an extra bit added to it. If one of the disks fails, your Internet sites shall continue working from the other ones and once we replace the malfunctioning one, the data that will be cloned on it will be recovered from what is stored on the rest of the drives together with the info from the parity disk. This is done so as to be able to recalculate the elements of every single file properly and to verify the integrity of the info copied on the new drive. This is another level of security for the content which you upload to your cloud web hosting account along with the ZFS file system that compares a special digital fingerprint for each file on all the 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 will be created is known as RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. Simply put, whenever any kind of data is copied on this special drive, one more bit is included to it and in case a defective disk is replaced, the data that will be cloned on it is a combination of the data on the other hard disks in the RAID and that on the parity one. This is done to guarantee that your data is intact. During this process, your websites will be functioning normally as RAID-Z enables a whole drive to fail without causing any service disruptions and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to ensure that no data shall get silently corrupted on our servers, you will not have to worry about the integrity of your files.
