RAID in 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 employs the so-called parity disk - a specific drive where info located on the other drives is copied with an extra bit added to it. If one of the disks stops functioning, your Internet sites shall continue working from the other ones and after we replace the problematic one, the info that will be copied on it will be recovered from what is stored on the rest of the drives as well as the information from the parity disk. This is done in order to be able to recalculate the elements of each and every file properly and to confirm the integrity of the data duplicated on the new drive. This is an additional level of security for the information you upload to your hosting account in addition to the ZFS file system which analyzes a unique digital fingerprint for each file on all the drives in real time.
RAID in Semi-dedicated Hosting
The info uploaded to any semi-dedicated hosting account is saved on SSD drives which function in RAID-Z. One of the drives in this kind of a setup is used for parity - whenever data is cloned on it, an extra bit is added. In case a disk turns out to be flawed, it will be taken out of the RAID without interrupting the operation of the sites as the data will load from the rest of the drives, and when a new drive is included, the data that will be duplicated on it will be a blend between the data on the parity disk and data saved on the other hard drives in the RAID. That is done to ensure that the information which is being copied is correct, so the moment the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is an extra guarantee for the integrity of your information because the ZFS file system which runs on our cloud Internet hosting platform compares a special checksum of all copies of your files on the various drives to be able to avoid any chance of silent data corruption.
