RAID in Cloud Web Hosting
Our advanced cloud web hosting platform where all cloud web hosting accounts are generated employs quick SSD drives instead of the traditional HDDs, and they operate in RAID-Z. With this setup, multiple hard drives operate together and at least one of them is a dedicated parity disk. Basically, when data is written on the other drives, it's copied on the parity one adding an extra bit. This is done for redundancy as even in case some drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, thus practically nothing will be lost and there will be no service interruptions. This is another level of protection for your data 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 Hosting
In case you host your websites in a semi-dedicated hosting account from our firm, all the content which you upload will be kept on SSD drives which work in RAID-Z. With this kind of RAID, at least one of the hard disks is employed for parity - when data is synchronized between the hard drives, an additional bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the data which is cloned to a new drive if one of the drives in the RAID stops working since the site content being copied on the brand new disk is recalculated from the information on the standard hard drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a drive fails, the system could switch to another one promptly without service disturbances of any kind. RAID-Z adds one more level of safety for the content that you upload on our cloud web hosting platform in addition to the ZFS file system which uses unique checksums in order to verify the integrity of every single file.
