RAID in Cloud Website Hosting
The state-of-the-art cloud Internet hosting platform where all cloud website hosting accounts are generated uses quick SSD drives rather than the standard HDDs, and they work in RAID-Z. With this setup, a number of hard drives operate together and at least one of them is a dedicated parity disk. Simply put, when data is written on the other drives, it is copied on the parity one adding an extra bit. This is done for redundancy as even in case a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified using the parity disk and the data recorded on the other ones, which means that nothing will be lost and there will not be any service disturbances. This is another level of protection for your information in addition to the revolutionary ZFS file system that uses checksums to ensure that all of the data on our servers is undamaged and is not silently corrupted.
RAID in Semi-dedicated Servers
The RAID type that we use for the cloud hosting platform where your semi-dedicated server account will be created is called 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 kind of data is copied on this particular hard drive, one more bit is included to it and if a faulty disk is replaced, the information which will be copied on it is a mix of the data on the other hard drives in the RAID and that on the parity one. This is done to make sure that your information is intact. During this process, your Internet sites will be up and running normally as RAID-Z allows for a whole drive to fail without any service disturbances 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 ensure that no data will get silently corrupted on our servers, you will never need to worry about the integrity of your files.
RAID in VPS Servers
All VPS server accounts which our company provides are created on physical servers that use SSD drives working in RAID. At least one drive is used for parity - one extra bit is included in the information cloned on it and in case a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the damaged drive so that the accurate data is restored on the new drive included in the RAID. Meanwhile, your websites will remain online because all the data will still load from at least 1 other drive. If you add routine backups to your VPS plan, a copy of your data will be stored on standard hard disks which also operate in RAID because we want to make certain that any website content you add will be risk-free at all times. Employing multiple drives in RAID for all the main and backup servers permits us to offer fast and reliable web hosting service.
