RAID in Cloud Web Hosting
The advanced cloud web hosting platform where all cloud web hosting accounts are made employs super fast SSD drives as an alternative to the traditional HDDs, and they function in RAID-Z. With this setup, multiple hard disk drives work together and at least 1 is a dedicated parity disk. In simple terms, when data is written on the other drives, it is duplicated on the parity one adding an extra bit. This is carried out for redundancy as even if a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, so nothing will be lost and there will not be any service disturbances. This is one more level of protection for your information in addition to the state-of-the-art ZFS file system that uses checksums to guarantee that all data on our servers is undamaged and is not silently corrupted.
RAID in Semi-dedicated Servers
The RAID type which we employ for the cloud web hosting platform where your semi-dedicated server account will be created is referred to as RAID-Z. What is different about it is that at least one of the disks is employed as a parity drive. Put simply, whenever any kind of data is copied on this special hard drive, one more bit is included to it and in case a malfunctioning disk is replaced, the information which will be duplicated on it is a mix of the data on the remaining drives in the RAID and that on the parity one. We do this to ensure that the information is intact. Throughout this process, your websites will be up and running normally because RAID-Z allows for a whole drive to fail without service interruptions 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 that uses checksums to warrant that no data will get silently corrupted on our servers, you won't ever have to worry about the integrity of your files.
