RAID in Shared Hosting
The revolutionary cloud hosting platform where all shared hosting accounts are made uses quick SSD drives as opposed to the classic HDDs, and they function in RAID-Z. With this setup, a number of hard disks work together and at least one of them is a dedicated parity disk. In simple terms, when data is written on the other drives, it's duplicated on the parity one adding an extra bit. This is done for redundancy as even if some drive fails or falls out of the RAID for some reason, the information can be rebuilt and verified using the parity disk and the data stored on the other ones, which means that not a single thing will be lost and there will be no service disturbances. This is an additional level of protection for your information along with the top-notch ZFS file system which uses checksums to guarantee that all data on our servers is undamaged and is not silently corrupted.
RAID in Semi-dedicated Hosting
The SSD drives that are used for keeping any content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a specific setup where one or more hard drives are used for parity i.e. the system will add an extra bit to any data cloned on this kind of a drive. If a disk fails and is substituted with another one, what data will be cloned on the latter shall be a mix calculated between the data on the other drives and that on the parity one. This is done to guarantee that the info on the new drive shall be accurate. Throughout the process, the RAID will continue working adequately and the malfunctioning drive won't have an impact on the proper operation of your Internet sites in any way. Using SSDs in RAID-Z is an outstanding addition to the ZFS file system that runs on our revolutionary cloud platform with respect to preserving the integrity of your files since ZFS uses unique digital identifiers named checksums so as to prevent silent data corruption.
