RAID in Cloud Hosting
The hard disks which we employ for storage with our outstanding cloud Internet hosting platform are not the classic HDDs, but fast solid-state drives (SSD). They work in RAID-Z - a special setup developed for the ZFS file system which we employ. Any content that you add to your cloud hosting account will be kept on multiple drives and at least one will be used as a parity disk. This is a specific drive where an additional bit is added to any content copied on it. If a disk in the RAID fails, it will be replaced without any service interruptions and the information will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the other disks. This is done so as to ensure the integrity of the info and together with the real-time checksum authentication that the ZFS file system executes on all drives, you'll never have to be concerned about the loss of any information no matter what.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud 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 employed as a parity drive. Put simply, whenever any kind of data is copied on this special disk drive, one more bit is added to it and if a malfunctioning disk is changed, the info that will be copied on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. This is done to guarantee that the information is intact. During this process, your sites will be functioning normally as RAID-Z enables a whole drive to fail without any service disturbances 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 shall get silently corrupted on our servers, you will not have to worry about the integrity of your files.
