RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform employs for storage operate in RAID-Z. This type of RAID is developed to work with the ZFS file system that 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 duplicated with an additional bit added to it. In case one of the disks fails, your websites will continue working from the other ones and after we replace the problematic one, the data which will be copied on it will be rebuilt from what is stored on the other drives as well as the info from the parity disk. This is performed in order to be able to recalculate the elements of each file properly and to authenticate the integrity of the information cloned on the new drive. This is one more level of security for the info that you upload to your cloud hosting account in addition to the ZFS file system which analyzes a unique digital fingerprint for each file on all the disk drives in real time.
RAID in Semi-dedicated Servers
The information uploaded to any semi-dedicated server account is stored on SSD drives that function in RAID-Z. One of the drives in type of a configuration is used for parity - each time data is copied on it, an additional bit is added. If a disk turns out to be problematic, it will be removed from the RAID without disturbing the operation of the sites as the data will load from the remaining drives, and when a new drive is included, the data which will be cloned on it will be a blend between the information on the parity disk and data stored on the other hard disks in the RAID. This is done to ensure that the info which is being copied is correct, so once the new drive is rebuilt, it can be included in the RAID as a production one. This is an extra warranty for the integrity of your data since the ZFS file system that runs on our cloud web hosting platform analyzes a special checksum of all of the copies of the files on the separate drives to avoid any chance of silent data corruption.
RAID in VPS Servers
All VPS server accounts which we offer are made on physical servers which employ SSD drives working in RAID. At least one drive is employed for parity - one additional bit is added to the information cloned on it and if a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the correct info is restored on the new drive added to the RAID. At the same time, your Internet sites will still be online since all the data will still load from at least 1 other drive. If you add routine backups to your VPS package, a copy of your information will be saved on standard disk drives which also work in RAID as we would like to make sure that any type of website content you add will be protected all the time. Working with multiple drives in RAID for all of the main and backup servers permits us to offer fast and reliable Internet hosting service.
