RAID in Web Hosting
The SSD drives that our cutting-edge cloud web hosting platform employs for storage work in RAID-Z. This kind 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 saved on the other drives is duplicated with an additional bit added to it. If one of the disks stops functioning, your websites will continue working from the other ones and once we replace the malfunctioning one, the data that will be copied on it will be rebuilt from what is stored on the rest of the drives along with the data from the parity disk. This is done in order to be able to recalculate the elements of each and every file properly and to verify the integrity of the data duplicated on the new drive. This is an additional level of security for the info that you upload to your web hosting account together with the ZFS file system which compares a special digital fingerprint for every single file on all hard drives in real time.
RAID in Semi-dedicated Hosting
If you host your sites within a semi-dedicated hosting account from our company, any content you upload will be held on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the disks is employed for parity - when data is synced between the disks, an extra bit is included in it on the parity one. The idea behind this is to ensure the integrity of the data which is duplicated to a brand new drive in case one of the hard drives in the RAID stops functioning since the website content being copied on the brand new disk is recalculated from the data on the standard disk drives and on the parity one. An additional advantage of RAID-Z is that even in the event that a disk drive stops functioning, the system could switch to another one quickly without service disruptions of any sort. RAID-Z adds one more level of security for the content you upload on our cloud hosting platform in addition to the ZFS file system which uses unique checksums so as to verify the integrity of each and every file.
RAID in VPS
In case you employ one of our virtual private server packages, any content which you upload will be stored on SSD drives which work in RAID. At least 1 drive is intended for parity so as to ensure the integrity of your data. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk within the RAID stops functioning, your websites will continue working and when a new disk takes the place of the defective one, the bits of the info that will be duplicated on it are calculated by using the healthy and the parity drives. By doing this, any possibility of corrupting data during the process is prevented. We also employ ordinary hard disks that operate in RAID for storing backups, so if you add this service to your VPS plan, your site content will be stored on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive breakdowns.
