RAID in Cloud Web Hosting
All content that you upload to your new cloud web hosting account will be placed on fast SSD drives which operate in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud Internet hosting platform and it adds an additional level of protection for your site content in addition to the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is saved on a number of disks and at least one is a parity disk - whenever information is recorded on it, an extra bit is added, so in case any drive stops working for some reason, the stability of the data can be verified by recalculating its bits based on what is kept on the production disks and on the parity one. With RAID-Z, the operation of our system won't be interrupted and it'll continue functioning smoothly until the malfunctioning drive is changed and the data is synchronized on it.
RAID in Semi-dedicated Hosting
The SSD drives which are used for keeping any content uploaded to the semi-dedicated hosting accounts that we offer work in RAID-Z. This is a special setup where one or more hard drives are used for parity i.e. the system will add an extra bit to any data duplicated on this kind of a hard drive. In case that a disk fails and is replaced with another one, what information will be duplicated on the latter shall be a mix calculated between the data on the other hard disks and that on the parity one. This is done to ensure that the information on the new drive will be accurate. During the procedure, the RAID will continue functioning normally and the problematic drive won't affect the normal operation of your sites at all. Using SSDs in RAID-Z is an excellent addition to the ZFS file system that runs on our top-notch cloud platform with regard to preserving the integrity of your files because ZFS uses specific digital identifiers named checksums so as to avoid silent data corruption.
RAID in VPS Hosting
If you use one of our virtual private server plans, any content which you upload will be saved on SSD drives which work in RAID. At least 1 drive is intended for parity so as to guarantee the integrity of the data. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk in the RAID stops working, your Internet sites will continue working and when a new disk substitutes the faulty one, the bits of the data that will be copied on it are calculated using the healthy and the parity drives. That way, any potential for corrupting data throughout the process is averted. We also employ regular hard drives that work in RAID for storing backups, so if you add this service to your VPS package, your content will be stored on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive breakdowns.
