RAID in Shared Web Hosting
The SSD drives which our cutting-edge cloud Internet hosting platform employs for storage work in RAID-Z. This sort of RAID is created to work with the ZFS file system which runs on the platform and it takes advantage of the so-called parity disk - a special drive where information stored on the other drives is cloned with an additional bit added to it. If one of the disks fails, your sites shall continue working from the other ones and once we replace the bad one, the information that will be copied on it will be recovered from what is stored on the other drives as well as the info from the parity disk. This is done so as to be able to recalculate the elements of every file adequately and to validate the integrity of the information duplicated on the new drive. This is another level of security for the information that you upload to your shared web hosting account along with the ZFS file system that compares a special digital fingerprint for each and every file on all hard drives in real time.
RAID in Semi-dedicated Hosting
In case you host your sites inside a semi-dedicated hosting account from our firm, all the content that you upload will be stored on SSD drives that work in RAID-Z. With this kind of RAID, at least 1 of the hard disks is employed for parity - when data is synced between the hard drives, an extra bit is included in it on the parity one. The reasoning behind this is to guarantee the integrity of the data which is copied to a new drive if one of the disks in the RAID stops working as the website content being copied on the brand new disk is recalculated from the info on the standard disk drives and on the parity one. Another advantage of RAID-Z is the fact that even in case a disk drive fails, the system can switch to a different one instantly without service disruptions of any sort. RAID-Z adds an extra level of security for the content that you upload on our cloud Internet hosting platform along with the ZFS file system that uses unique checksums as a way to validate the integrity of each file.
RAID in VPS Web Hosting
The SSD drives that we use on the physical machines where we generate virtual private servers operate in RAID to ensure that any content which you upload will be available and intact all the time. At least one drive is used for parity - one bit of information is added to any data copied on it. If a main drive breaks down, it is changed and the info which will be copied on it is calculated between the remaining drives and the parity one. It's done this way to make sure that the correct info is copied and that not a single file is corrupted because the new drive will be a part of the RAID afterwards. In addition, we use hard drives functioning in RAID on the backup servers, so in case you add this upgrade to your VPS plan, you'll use an even more reliable web hosting service as your content will be available on multiple drives irrespective of any type of unforeseen hardware malfunction.
