RAID in Web Hosting
The SSD drives that our cutting-edge cloud web hosting platform uses for storage function in RAID-Z. This sort of RAID is developed to work with the ZFS file system that runs on the platform and it works by using the so-called parity disk - a special drive where info kept on the other drives is duplicated with an additional bit added to it. In the event that one of the disks stops functioning, your Internet sites shall continue working from the other ones and after we replace the faulty one, the info that will be copied on it will be recovered from what is stored on the remaining drives along with the information from the parity disk. This is performed in order to be able to recalculate the bits of each and every file adequately and to authenticate the integrity of the data cloned on the new drive. This is an additional level of security for the content that you upload to your web hosting account in addition to the ZFS file system that compares a unique digital fingerprint for each file on all drives in real time.
RAID in Semi-dedicated Servers
The RAID type that we use for the cloud web hosting platform where your semi-dedicated server account will be created is known as RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. In simple terms, whenever any data is cloned on this particular drive, one more bit is added to it and in the event that a faulty disk is changed, the data that will be copied on it is a combination of the data on the other hard drives in the RAID and that on the parity one. We do this to make sure that the info is intact. During this process, your Internet sites will be functioning normally because RAID-Z allows for a whole drive to fail without any service disturbances and it simply uses one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to warrant that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts which our company offers are created on physical servers that employ SSD drives functioning in RAID. At least one drive is used for parity - one extra bit is included in the info duplicated on it and if a main disk stops working, this bit makes it simpler to recalculate the bits of the files on the damaged drive so that the correct data is restored on the new drive added to the RAID. At the same time, your Internet sites will stay online since all the information will still load from at least 1 more hard drive. If you add routine backups to your VPS plan, a copy of your information will be stored on standard hard disks that also work in RAID since we want to make sure that any kind of website content you upload will be risk-free all the time. Using multiple hard disks in RAID for all the main and backup servers allows us to offer fast and reliable hosting service.
