RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud web hosting platform uses for storage operate in RAID-Z. This type of RAID is created to work with the ZFS file system which runs on the platform and it works by using the so-called parity disk - a special drive where information stored on the other drives is duplicated with an extra bit added to it. If one of the disks fails, your sites shall continue working from the other ones and after we replace the problematic one, the information that will be duplicated on it will be recovered from what is stored on the rest of the drives together with the info from the parity disk. This is done in order to be able to recalculate the bits of every file correctly and to confirm the integrity of the data duplicated on the new drive. This is another level of security for the information that you upload to your cloud hosting account along with the ZFS file system which analyzes a unique digital fingerprint for each and every file on all disk drives in real time.
RAID in Semi-dedicated Hosting
The information uploaded to any semi-dedicated hosting account is stored on SSD drives that work in RAID-Z. One of the drives in type of a configuration is used for parity - whenever data is cloned on it, an additional bit is added. If a disk turns out to be defective, it will be removed from the RAID without disturbing the functioning of the Internet sites since the data will load from the rest of the drives, and when a new drive is included, the info that will be duplicated on it will be a blend between the information on the parity disk and data kept on the other hard drives in the RAID. This is done so as to ensure that the info that is being copied is accurate, so as soon as the new drive is rebuilt, it can be included in the RAID as a production one. This is one more warranty for the integrity of your info as the ZFS file system which runs on our cloud hosting platform analyzes a unique checksum of all of the copies of your files on the different drives so as to avoid any possibility of silent data corruption.
RAID in VPS Web Hosting
All virtual private server accounts which our company provides are created on physical servers which take advantage of SSD drives functioning in RAID. At least one drive is intended for parity - one extra bit is added to the data cloned on it and if a main disk fails, this bit makes it much simpler to recalculate the bits of the files on the failed disk drive so that the correct info is restored on the new drive added to the RAID. At the same time, your sites will remain online since all the data will still load from at least one more hard drive. If you add regular backups to your VPS plan, a copy of your info will be stored on standard hard drives that also work in RAID because we would like to make certain that any website content you add will be protected all the time. Working with multiple hard drives in RAID for all of the main and backup servers permits us to offer fast and reliable Internet hosting service.
