RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This type of RAID is designed to work with the ZFS file system which runs on the platform and it employs the so-called parity disk - a special drive where info kept on the other drives is cloned with an extra bit added to it. If one of the disks stops functioning, your websites will continue working from the other ones and after we replace the bad one, the data which will be duplicated on it will be recovered from what is stored on the rest of the drives as well as the data from the parity disk. This is performed in order to be able to recalculate the elements of every file adequately and to confirm the integrity of the data cloned on the new drive. This is one more level of security for the information you upload to your cloud hosting account in addition to the ZFS file system that compares a unique digital fingerprint for each file on all disk drives in real time.
RAID in Semi-dedicated Servers
The RAID type which we employ for the cloud hosting platform where your semi-dedicated server account shall be created is referred to as RAID-Z. What's different about it is that at least one of the disks is used as a parity drive. In simple terms, whenever any kind of data is cloned on this special hard drive, one more bit is added to it and in the event that a malfunctioning disk is changed, the info that will be duplicated on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. This is done to make sure that the info is intact. During this process, your Internet sites will be functioning normally since RAID-Z allows for an entire drive to fail without causing any service interruptions and it simply works by using one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to guarantee that no data will get silently corrupted on our servers, you won't need to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts that we provide are created on physical servers which use SSD drives functioning in RAID. At least 1 drive is used for parity - one additional bit is included in the info cloned on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the failed disk drive so that the right information is restored on the new drive added to the RAID. Meanwhile, your Internet sites will remain online because all the information will still load from at least one more hard drive. In case you add routine backups to your VPS package, a copy of the information will be kept on standard disk drives which also work in RAID since we want to make certain that any kind of site content you upload will be risk-free all the time. Employing multiple drives in RAID for all the main and backup servers allows us to offer fast and reliable Internet hosting service.
