RAID in Cloud Hosting
Any content which you upload to your new cloud hosting account will be held on quick SSD drives that operate in RAID-Z. This setup is built to work with the ZFS file system which runs on our cloud Internet hosting platform and it adds another level of security for your website content in addition to the real-time checksum verification which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on several disks and at least 1 is a parity disk - whenever information is written on it, an additional bit is added, so if any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits based on what is kept on the production hard drives and on the parity one. With RAID-Z, the operation of our system won't be interrupted and it'll continue functioning efficiently until the problematic drive is replaced and the information is synchronized on it.
RAID in Semi-dedicated Servers
In case you host your websites in a semi-dedicated server account from our firm, all of the content that you upload will be kept on SSD drives which operate in RAID-Z. With this kind of RAID, at least one of the drives is employed for parity - when data is synced between the hard drives, an additional bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the info that is duplicated to a brand new drive if one of the disks in the RAID fails because the website content being copied on the brand new disk is recalculated from the data on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even in case a hard drive stops functioning, the system can switch to another one instantly without service disruptions of any type. RAID-Z adds an extra level of safety for the content you upload on our cloud hosting platform together with the ZFS file system which uses unique checksums as a way to authenticate the integrity of every single file.
