RAID in Website Hosting
Any content which you upload to your new website hosting account will be placed on fast SSD drives that operate in RAID-Z. This configuration is built to employ the ZFS file system that runs on our cloud web hosting platform and it adds one more level of security for your site content on top of the real-time checksum authentication 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 recorded on it, an additional bit is added, so if any drive stops working for whatever reason, the stability of the data can be verified by recalculating its bits based on what is stored on the production disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue operating flawlessly until the problematic drive is replaced and the information is synced on it.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud hosting platform where your semi-dedicated server account will be created is named RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. In simple terms, whenever any data is cloned on this special disk drive, one more bit is added to it and in the event that a problematic disk is changed, the information that will be duplicated on it is a mix of the data on the remaining drives in the RAID and that on the parity one. This is done to make sure that the information is intact. During this process, your Internet sites will be up and running normally because RAID-Z makes it possible for an entire drive to fail without any service interruptions 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 ensure that no data will get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
