RAID in Hosting
Our state-of-the-art cloud Internet hosting platform where all hosting accounts are made employs fast SSD drives as an alternative to the traditional HDDs, and they work in RAID-Z. With this configuration, several hard disk drives operate together and at least one is a dedicated parity disk. In simple terms, when data is written on the remaining drives, it's copied on the parity one adding an extra bit. This is carried out for redundancy as even in case a drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, therefore nothing will be lost and there will be no service disorders. This is one more level of protection for your data along with the top-notch ZFS file system which uses checksums to guarantee that all the data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Servers
The SSD drives which are used for storing any site content uploaded to the semi-dedicated server accounts which we offer operate in RAID-Z. This is a specific configuration where one or more hard drives are employed for parity i.e. the system will include an additional bit to any data duplicated on this kind of a drive. If a disk fails and is replaced with another one, what information will be duplicated on the latter will be a mix calculated between the data on the other hard disks and that on the parity one. This is done to ensure that the information on the new drive will be correct. Throughout the process, the RAID will continue working normally and the malfunctioning drive will not affect the adequate operation of your sites at all. Working with SSDs in RAID-Z is an impressive addition to the ZFS file system which runs on our advanced cloud platform with regards to preserving the integrity of your files because ZFS uses special digital identifiers called checksums so as to avoid silent data corruption.
RAID in VPS Servers
In case you employ one of our VPS server packages, any content that you upload will be saved on SSD drives that operate in RAID. At least one drive is employed for parity to guarantee the integrity of the information. In simple terms, this is a special drive where data is copied with one bit added to it. In case a disk from the RAID fails, your sites will continue working and when a new disk takes the place of the faulty one, the bits of the information that will be cloned on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is prevented. We also employ conventional hard disks which operate in RAID for storing backups, so if you add this service to your VPS package, your content will be kept on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive breakdowns.
