RAID in Website Hosting
The SSD drives which our cutting-edge cloud hosting platform uses for storage function in RAID-Z. This type of RAID is designed to work with the ZFS file system which runs on the platform and it works by using the so-called parity disk - a specific drive where data kept on the other drives is copied with an additional bit added to it. In case one of the disks stops working, your sites will continue working from the other ones and after we replace the malfunctioning one, the data which will be copied on it will be recovered from what is stored on the rest of the drives as well as the info from the parity disk. This is done in order to be able to recalculate the bits of each and every file adequately and to authenticate the integrity of the information duplicated on the new drive. This is one more level of security for the information which you upload to your website hosting account in addition to the ZFS file system which compares a unique digital fingerprint for every single file on all of the drives in real time.
RAID in Semi-dedicated Hosting
If you host your sites within a semi-dedicated hosting account from our company, all of the content that you upload will be held on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the hard disks is used for parity - when data is synchronized between the drives, an extra bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the info that is duplicated to a new drive in the event that one of the disks in the RAID stops working because the site content being copied on the brand new disk is recalculated from the data on the standard drives and on the parity one. Another advantage of RAID-Z is that even if a hard drive stops working, the system could switch to a different one immediately without service interruptions of any kind. RAID-Z adds an extra level of safety for the content that you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums in order to verify the integrity of each file.
RAID in VPS Web Hosting
The SSD drives that we use on the physical machines where we create virtual private servers function in RAID to make sure that any content which you upload will be available and intact all the time. At least one drive is employed for parity - one bit of info is added to any data copied on it. If a main drive breaks down, it is replaced and the info that will be copied on it is calculated between the remaining drives and the parity one. That’s done to make sure that the right info is copied and that not a single file is corrupted since the new drive will be used in the RAID afterwards. Also, we use hard disks working in RAID on the backup servers, so if you add this upgrade to your VPS package, you'll use an even more reliable Internet hosting service as your content will be available on multiple drives regardless of any type of unexpected hardware malfunction.
