RAID in Cloud Website Hosting
The cutting-edge cloud web hosting platform where all cloud website hosting accounts are made uses fast SSD drives as an alternative to the traditional HDDs, and they work in RAID-Z. With this setup, a number of hard disk drives function together and at least a single one is a dedicated parity disk. Basically, when data is written on the other drives, it is cloned on the parity one adding an extra bit. This is carried out for redundancy as even if a 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 recorded on the other ones, thus practically nothing will be lost and there will be no service interruptions. This is one more level of security for your information along with the revolutionary ZFS file system which uses checksums to make sure 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 site content uploaded to the semi-dedicated hosting accounts which we provide operate in RAID-Z. This is a specific configuration where one or more disk drives are employed for parity i.e. the system will include an extra bit to any data copied on this kind of a disk drive. In the event that a disk fails and is replaced with another one, what info will be copied on the latter will be a combination calculated between the data on the remaining hard disks and that on the parity one. This is done to ensure that the data on the new drive shall be accurate. During the process, the RAID will continue functioning adequately and the malfunctioning drive won't impact the proper operation of your sites at all. Working with SSDs in RAID-Z is a superb addition to the ZFS file system that runs on our cutting-edge cloud platform in terms of preserving the integrity of your files because ZFS uses specific digital identifiers identified as checksums so as to avoid silent data corruption.
