RAID in Cloud Web Hosting
All of the content which you upload to your new cloud web hosting account will be held on fast SSD drives that work in RAID-Z. This setup is built to employ the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of protection for your content on top of the real-time checksum authentication which ZFS uses to ensure the integrity of the data. With RAID-Z, the info is saved on a couple of disks and at least one of them is a parity disk - whenever info is written on it, an additional bit is added, so if any drive stops working for some reason, the integrity of the information can be verified by recalculating its bits in accordance with what is saved on the production disks and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue operating smoothly until the faulty drive is changed and the data is synced on it.
RAID in Semi-dedicated Hosting
The RAID type which we employ for the cloud web hosting platform where your semi-dedicated hosting account will be created is named RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. In simple terms, whenever any data is duplicated on this particular hard drive, one more bit is included to it and if a faulty disk is changed, the data which will be duplicated on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. We do this to make sure that your data is intact. Throughout this process, your sites will be up and running normally because RAID-Z makes it possible for a whole drive to fail without service disturbances and it simply uses one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to warrant that no data will get silently corrupted on our servers, you won't ever have to worry about the integrity of your files.
