RAID in Cloud Website Hosting
The drives which we employ for storage with our outstanding cloud Internet hosting platform are not the standard HDDs, but quick solid-state drives (SSD). They operate in RAID-Z - a special setup created for the ZFS file system which we use. All the content that you add to the cloud website hosting account will be held on multiple drives and at least 1 shall be employed as a parity disk. This is a special drive where an additional bit is included to any content copied on it. If a disk in the RAID fails, it will be replaced without any service disturbances and the data will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk plus that on the remaining disks. This is done to ensure the integrity of the info and along with the real-time checksum verification that the ZFS file system executes on all drives, you will never have to be concerned about the loss of any information no matter what.
RAID in Semi-dedicated Servers
The RAID type that we use for the cloud hosting platform where your semi-dedicated server account will be created is referred to as RAID-Z. What's different about it is that at least 1 of the disks is used as a parity drive. In simple terms, whenever any data is cloned on this specific hard drive, one more bit is included to it and in the event that a defective disk is replaced, the information that will be copied on it is a combination of the data on the other hard drives in the RAID and that on the parity one. This is done to guarantee that the info is intact. During this process, your sites will be up and running normally as RAID-Z enables a whole drive to fail without causing any service disturbances and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to ensure that no data shall get silently corrupted on our servers, you won't need to worry about the integrity of your files.
