RAID in Web Hosting
The advanced cloud web hosting platform where all web hosting accounts are created employs super fast SSD drives as an alternative to the traditional HDDs, and they work in RAID-Z. With this setup, multiple hard disk drives work together and at least one is a dedicated parity disk. Put simply, when data is written on the other drives, it is 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 thanks to the parity disk and the data recorded on the other ones, thus not a single thing will be lost and there will be no service interruptions. This is one more level of security for your data in addition to the revolutionary ZFS file system that uses checksums to ensure that all data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Servers
The SSD drives which are used for holding any content uploaded to the semi-dedicated server accounts which we provide work in RAID-Z. This is a special configuration where one or more hard drives are used for parity i.e. the system will include an additional bit to any data cloned on this type of a drive. In case that a disk fails and is replaced with a new one, what data will be copied on the latter shall be a mix calculated between the data on the remaining drives and that on the parity one. This is done to guarantee that the info on the new drive will be correct. During the procedure, the RAID will continue operating normally and the malfunctioning drive won't have an effect on the adequate operation of your Internet sites by any means. Working with SSDs in RAID-Z is an excellent addition to the ZFS file system that runs on our state-of-the-art cloud platform with respect to preserving the integrity of your files as ZFS uses unique digital identifiers named checksums to prevent silent data corruption.
