RAID in Web Hosting
All of the content that you upload to your new web hosting account will be placed on quick SSD drives which work in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud web hosting platform and it adds an additional level of security for your site content in addition to the real-time checksum verification that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on several disks and at least one is a parity disk - whenever info is written on it, an extra bit is added, so if any drive fails for whatever reason, the integrity of the data can be verified by recalculating its bits in accordance with what is saved on the production hard disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating flawlessly until the problematic drive is changed and the info is synced on it.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud hosting platform where your semi-dedicated hosting account shall be created is known as RAID-Z. What's different about it is that at least one of the disks is employed as a parity drive. Simply put, whenever any kind of data is cloned on this special drive, one more bit is included to it and if a malfunctioning disk is changed, the information that will be copied on it is a mix of the data on the remaining hard disks in the RAID and that on the parity one. This is done to ensure that your data is intact. Throughout this process, your websites will be functioning normally because RAID-Z makes it possible for a whole drive to fail without service disturbances and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to warrant that no data will get silently corrupted on our servers, you will never have to worry about the integrity of your files.
