RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function in RAID-Z. This type of RAID is designed to work with the ZFS file system that runs on the platform and it uses the so-called parity disk - a specific drive where data located on the other drives is duplicated with an extra bit added to it. In case one of the disks stops working, your sites shall continue working from the other ones and after we replace the bad one, the info which will be duplicated on it will be recovered from what is stored on the remaining drives along with the information from the parity disk. This is done in order to be able to recalculate the elements of every single file adequately and to confirm the integrity of the info copied on the new drive. This is one more level of security for the information which you upload to your cloud hosting account together with the ZFS file system which analyzes a unique digital fingerprint for every single file on all hard drives in real time.
RAID in Semi-dedicated Servers
In case you host your sites in a semi-dedicated server account from our firm, all the content that you upload will be stored on SSD drives that work in RAID-Z. With this type of RAID, at least 1 of the hard drives is employed for parity - when data is synced between the drives, an extra bit is added to it on the parity one. The idea behind this is to guarantee the integrity of the info that is duplicated to a brand new drive if one of the drives in the RAID stops functioning since the site 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 the fact that even if a disk drive stops functioning, the system could switch to another one instantly without service disruptions of any sort. RAID-Z adds one more level of protection for the content that you upload on our cloud hosting platform along with the ZFS file system which uses unique checksums so as to authenticate the integrity of each file.
