RAID in Cloud Web Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage work in RAID-Z. This sort of RAID is created to work with the ZFS file system which runs on the platform and it takes advantage of the so-called parity disk - a special drive where data located on the other drives is copied with an additional bit added to it. In the event that one of the disks fails, your sites will continue working from the other ones and as soon as we replace the malfunctioning one, the info which will be copied on it will be recovered from what is stored on the remaining drives along with the data from the parity disk. This is done so as to be able to recalculate the bits of each and every file correctly and to confirm the integrity of the info copied on the new drive. This is an additional level of security for the info which you upload to your cloud web hosting account together with the ZFS file system which analyzes a special digital fingerprint for every single file on all hard drives in real time.
RAID in Semi-dedicated Servers
The RAID type which we use for the cloud Internet hosting platform where your semi-dedicated server account will be created is known as RAID-Z. What's different about it is that at least one of the disks is used as a parity drive. Simply put, whenever any data is duplicated on this particular disk drive, one more bit is added to it and in case a defective disk is replaced, the information that will be duplicated on it is a mix of the data on the remaining drives in the RAID and that on the parity one. This is done to ensure that your info is intact. During this process, your Internet sites will be working normally as RAID-Z allows for a whole drive to fail without causing any service disturbances and it simply uses one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to ensure that no data can get silently corrupted on our servers, you won't have to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts which we provide are made on physical servers which use SSD drives functioning in RAID. At least 1 drive is intended for parity - one extra bit is included in the information cloned on it and if a main disk fails, this bit makes it easier to recalculate the bits of the files on the failed drive so that the right information is recovered on the new drive included in the RAID. At the same time, your websites will still be online since all the data will still load from at least 1 more hard disk. If you add routine backups to your VPS plan, a copy of your info will be kept on standard hard disks which also operate in RAID as we would like to make sure that any site content you upload will be risk-free at all times. Working with multiple hard disks in RAID for all the main and backup servers allows us to offer fast and reliable hosting service.
