RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud web hosting platform uses for storage function in RAID-Z. This kind of RAID is developed to work with the ZFS file system that runs on the platform and it employs the so-called parity disk - a special drive where data located on the other drives is duplicated with an extra bit added to it. In the event that one of the disks fails, your sites will continue working from the other ones and as soon as we replace the malfunctioning one, the data that will be copied on it will be recovered from what is stored on the other drives together with the data from the parity disk. This is done in order to be able to recalculate the bits of every single file properly and to confirm the integrity of the info copied on the new drive. This is an additional level of security for the information which you upload to your cloud hosting account together with the ZFS file system that compares a special digital fingerprint for every single file on all of the disk drives in real time.
RAID in Semi-dedicated Hosting
In case you host your Internet sites within a semi-dedicated hosting account from our company, all of the content which you upload will be saved on SSD drives which work in RAID-Z. With this kind of RAID, at least 1 of the hard drives is employed for parity - when data is synchronized between the hard drives, 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 the event that one of the drives in the RAID stops functioning as the site content being copied on the brand new disk is recalculated from the info on the standard drives and on the parity one. An additional advantage of RAID-Z is that even in case a disk drive fails, the system can easily switch to a different one instantly without service interruptions of any sort. RAID-Z adds an extra level of protection for the content that you upload on our cloud hosting platform together with the ZFS file system which uses unique checksums to validate the integrity of every single file.
RAID in VPS
The SSD drives that we use on the physical machines where we set up virtual private servers operate in RAID to make sure that any content that you upload will be available and intact all the time. At least a single drive is employed for parity - one bit of data is added to any data cloned on it. In case a main drive stops working, it is changed and the info which will be duplicated on it is calculated between the rest of the drives and the parity one. It's done this way to ensure that the right info is copied and that no file is corrupted since the new drive will be incorporated into the RAID afterwards. We also use hard disks functioning in RAID on the backup servers, so if you add this upgrade to your VPS plan, you'll use an even more reliable Internet hosting service because your content will be available on multiple drives regardless of any sort of sudden hardware malfunction.
