RAID in Cloud Hosting
The SSD drives which our cutting-edge cloud web hosting platform uses for storage work in RAID-Z. This type of RAID is designed to work with the ZFS file system that runs on the platform and it works by using the so-called parity disk - a specific drive where data located on the other drives is cloned with an additional bit added to it. If one of the disks stops functioning, your websites shall continue working from the other ones and once we replace the bad one, the information which will be cloned on it will be rebuilt from what is stored on the rest of the drives along with the info from the parity disk. This is done in order to be able to recalculate the bits of each file adequately and to authenticate the integrity of the data cloned on the new drive. This is another level of security for the info that you upload to your cloud hosting account in addition to the ZFS file system which analyzes a special digital fingerprint for each file on all the hard drives in real time.
RAID in Semi-dedicated Hosting
If you host your websites in a semi-dedicated hosting account from our company, all the content that you upload will be stored on SSD drives which work in RAID-Z. With this form of RAID, at least one of the drives is used for parity - when data is synced between the drives, an extra 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 in the event that one of the drives in the RAID fails since the content being copied on the new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in the event that a disk drive stops functioning, the system can easily switch to a different one instantly without service disruptions of any sort. RAID-Z adds one more level of safety for the content you upload on our cloud Internet hosting platform together with the ZFS file system that uses unique checksums to validate the integrity of every single file.
RAID in VPS
If you employ one of our virtual private server plans, any content which you upload will be stored on SSD drives that function in RAID. At least one drive is used for parity to ensure the integrity of your data. In simple terms, this is a special drive where information is copied with one bit added to it. In case a disk from the RAID stops working, your Internet sites will continue working and when a new disk substitutes the defective one, the bits of the data that will be duplicated on it are calculated using the healthy and the parity drives. That way, any chance of corrupting data during the process is prevented. We also use standard hard disks which work in RAID for storing backups, so if you include this service to your VPS package, your site content will be kept on multiple drives and you will never need to worry about its integrity even in the event of multiple drive failures.
