RAID in Web Hosting
Any content which you upload to your new web hosting account will be held on quick SSD drives that function in RAID-Z. This configuration is built to employ the ZFS file system that runs on our cloud Internet hosting platform and it adds another level of protection for your content on top of the real-time checksum validation which ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is stored on several disks and at least one of them is a parity disk - whenever info is written on it, an additional bit is added, so in the event that any drive stops functioning for whatever reason, the stability of the info can be verified by recalculating its bits based on what is saved on the production drives and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue functioning effectively until the problematic drive is replaced and the information is synced on it.
RAID in Semi-dedicated Servers
The SSD drives that are used for saving any content uploaded to the semi-dedicated server accounts that we provide function in RAID-Z. This is a special configuration where one or more hard drives are employed for parity i.e. the system will add an additional bit to any data duplicated on such a disk drive. If a disk fails and is substituted with a new one, what info will be copied on the latter shall be a combination calculated between the data on the other hard disks and that on the parity one. This is done to guarantee that the information on the new drive shall be accurate. During the process, the RAID will continue working normally and the faulty drive will not impact the normal operation of your sites in any way. Using SSDs in RAID-Z is a fantastic addition to the ZFS file system that runs on our advanced cloud platform with respect to preserving the integrity of your files as ZFS uses unique digital identifiers named checksums in order to avoid silent data corruption.
RAID in VPS Servers
The SSD drives which we use on the machines where we set up VPS servers function in RAID to make sure that any content which you upload will be available and intact at all times. At least one drive is employed for parity - one bit of information is added to any data cloned on it. If a main drive breaks down, it is replaced and the data which will be duplicated on it is calculated between the other drives and the parity one. It's done this way to make sure that the required info is copied and that no file is corrupted as the new drive will be included in the RAID afterwards. Also, we use hard drives functioning in RAID on the backup servers, so in case you add this upgrade to your VPS package, you will use an even more reliable Internet hosting service as your content will be available on multiple drives regardless of any kind of unforeseen hardware malfunction.
