RAID in Shared Hosting
The hard disks which we employ for storage with our outstanding cloud web hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup created for the ZFS file system which we use. Any content that you add to the shared hosting account will be stored on multiple disk drives and at least one will be employed as a parity disk. This is a special drive where an additional bit is added to any content copied on it. In the event that a disk in the RAID stops functioning, it will be changed without any service disturbances and the data will be recovered on the new drive by recalculating its bits using the data on the parity disk along with that on the other disks. This is done so as to guarantee the integrity of the info and together with the real-time checksum authentication which the ZFS file system executes on all drives, you will never have to worry about the loss of any info no matter what.
RAID in Semi-dedicated Hosting
In case you host your Internet sites in a semi-dedicated hosting account from our company, all of the content which you upload will be stored on SSD drives which operate in RAID-Z. With this kind of RAID, at least one of the hard disks is employed for parity - when data is synchronized between the hard drives, an additional bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the info that is duplicated to a new drive in case one of the hard drives in the RAID stops working because the site content being copied on the new disk is recalculated from the data on the standard disk drives and on the parity one. An additional advantage of RAID-Z is the fact that even in the event that a drive stops functioning, the system can switch to another one promptly without service disturbances of any type. RAID-Z adds one more level of security for the content that you upload on our cloud web hosting platform in addition to the ZFS file system that uses unique checksums in order to authenticate the integrity of every single file.
RAID in VPS
If you employ one of our virtual private server solutions, any content that you upload will be stored on SSD drives that function in RAID. At least a single drive is intended for parity to guarantee the integrity of your info. 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 takes the place of the flawed one, the bits of the info that will be duplicated on it are calculated using the healthy and the parity drives. That way, any probability of corrupting data during the process is prevented. We also use ordinary hard disks which function in RAID for storing backup copies, so in case you include this service to your VPS plan, your content will be kept on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
