RAID in Shared Hosting
Our cutting-edge cloud web hosting platform where all shared hosting accounts are made employs super fast SSD drives instead of the traditional HDDs, and they operate in RAID-Z. With this setup, a number of hard disks function together and at least a single one is a dedicated parity disk. Basically, when data is written on the rest of the drives, it's cloned on the parity one adding an extra bit. This is done for redundancy as even if a drive fails or falls out of the RAID for whatever reason, the info can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, which means that not a single thing will be lost and there will not be any service interruptions. This is another level of protection for your data in addition to the cutting-edge ZFS file system which uses checksums to ensure that all of the data on our servers is undamaged and is not silently corrupted.
RAID in Semi-dedicated Hosting
The SSD drives that are used for storing any content uploaded to the semi-dedicated hosting accounts that we offer operate in RAID-Z. This is a specific configuration where one or more hard drives are used for parity i.e. the system will add an extra bit to any data duplicated on this kind of a drive. In case that a disk fails and is substituted with a new one, what data will be cloned on the latter shall be a mix calculated between the data on the other hard disks and that on the parity one. This is done to guarantee that the info on the new drive shall be accurate. During the procedure, the RAID will continue working adequately and the faulty drive won't have an impact on the proper operation of your sites in any respect. Using SSDs in RAID-Z is an excellent addition to the ZFS file system which runs on our revolutionary cloud platform with regard to preserving the integrity of your files because ZFS uses special digital identifiers called checksums to prevent silent data corruption.
RAID in VPS
The SSD drives which we use on the physical machines where we create virtual private servers operate in RAID to make sure that any content which you upload will be available and intact all of the time. At least 1 drive is used for parity - one bit of info is added to any data cloned on it. If a main drive breaks down, it is replaced and the info that will be cloned on it is calculated between the other drives and the parity one. It's done this way to make sure that the needed info is copied and that not a single file is corrupted as the new drive will be included in the RAID afterwards. We also use hard disk drives functioning in RAID on the backup servers, so in case you add this upgrade to your VPS package, you'll use an even more reliable Internet hosting service as your content will be available on multiple drives regardless of any type of unexpected hardware malfunction.
