RAID in Cloud Website Hosting
All content which you upload to your new cloud website hosting account will be saved on quick SSD drives which operate in RAID-Z. This setup is built to work with the ZFS file system which runs on our cloud hosting platform and it adds one more level of security for your site content in addition to the real-time checksum validation which ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least 1 is a parity disk - whenever info is written on it, an additional bit is added, so in the event that any drive fails for some reason, the stability of the info can be verified by recalculating its bits in accordance with what is saved on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating effectively until the faulty drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Servers
The RAID type which we employ for the cloud hosting platform where your semi-dedicated server account shall be created is referred to as RAID-Z. What is 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 duplicated on this particular drive, one more bit is included to it and in the event that a problematic disk is replaced, the information that will be copied on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. This is done to guarantee that your info is intact. Throughout this process, your websites will be working normally as RAID-Z enables an entire drive to fail without any service disruptions and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to guarantee that no data will get silently corrupted on our servers, you'll never have to worry about the integrity of your files.
