RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function 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 kept on the other drives is duplicated with an extra bit added to it. In case one of the disks stops working, your websites shall continue working from the other ones and after we replace the faulty one, the info which will be duplicated on it will be recovered from what is stored on the rest of the drives as well as the information from the parity disk. This is done so as to be able to recalculate the bits of every file correctly and to authenticate the integrity of the data cloned on the new drive. This is another level of security for the info that you upload to your cloud hosting account together with the ZFS file system that analyzes a unique digital fingerprint for each file on all of the disk drives in real time.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is kept on SSD drives which work in RAID-Z. One of the drives in such a setup is used for parity - every time data is copied on it, an additional bit is added. In case a disk turns out to be defective, it will be removed from the RAID without interrupting the operation of the Internet sites as the data will load from the rest of the drives, and when a brand new drive is included, the information that will be cloned on it will be a combination between the data on the parity disk and data kept on the other hard drives in the RAID. This is done to guarantee that the data which is being copied is accurate, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is an extra guarantee for the integrity of your information since the ZFS file system which runs on our cloud web hosting platform compares a unique 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 intended for parity - one extra bit is included in the information copied on it and in case 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 information is restored on the new drive added to the RAID. Meanwhile, your Internet sites will stay online since all the info will still load from at least 1 more disk drive. If you add routine backups to your VPS plan, a copy of the info will be saved on standard hard drives that also work in RAID since we would like to make sure that any content you upload will be protected at all times. Working with multiple drives in RAID for all the main and backup servers permits us to offer fast and reliable web hosting service.
