RAID in Website Hosting
The SSD drives which our cutting-edge cloud hosting platform employs for storage work in RAID-Z. This sort of RAID is intended to work with the ZFS file system which runs on the platform and it employs the so-called parity disk - a specific drive where information kept on the other drives is copied with an additional bit added to it. In the event that one of the disks fails, your Internet sites will continue working from the other ones and after we replace the faulty one, the information which will be cloned on it will be recovered from what is stored on the other drives together with the data from the parity disk. This is performed in order to be able to recalculate the elements of each file properly and to verify the integrity of the data duplicated on the new drive. This is one more level of security for the info you upload to your website hosting account along with the ZFS file system which analyzes a special digital fingerprint for each and every file on all of the disk drives in real time.
RAID in Semi-dedicated Servers
The SSD drives that are used for saving any website content uploaded to the semi-dedicated server accounts which we offer operate in RAID-Z. This is a specific setup where one or more drives are used for parity i.e. the system will include an additional bit to any data cloned on such a disk drive. If a disk fails and is replaced with another one, what data will be copied on the latter will be a mix calculated between the data on the other disks and that on the parity one. This is done to make sure that the information on the new drive shall be accurate. Throughout the process, the RAID will continue working adequately and the problematic drive will not have an effect on the normal operation of your Internet sites in any respect. Using SSDs in RAID-Z is a superb addition to the ZFS file system that runs on our top-notch cloud platform with regard to preserving the integrity of your files as ZFS uses special digital identifiers known as checksums so as to prevent silent data corruption.
RAID in VPS Servers
In case you use one of our VPS server packages, any content which you upload will be stored on SSD drives which work in RAID. At least a single drive is employed for parity to guarantee the integrity of your info. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk part of the RAID stops functioning, your websites will continue working and when a new disk takes the place of the flawed one, the bits of the data that will be cloned on it are calculated using the healthy and the parity drives. That way, any possibility of corrupting data throughout the process is averted. We also employ regular hard disk drives that operate in RAID for storing backup copies, so in case you include this service to your VPS package, your website content will be kept on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive breakdowns.
