RAID in Shared Hosting
The SSD drives which our cutting-edge cloud Internet hosting platform employs for storage function in RAID-Z. This sort 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 info stored on the other drives is cloned with an extra bit added to it. In the event that one of the disks stops functioning, your Internet sites will continue working from the other ones and as soon as we replace the bad one, the information that will be duplicated on it will be rebuilt from what is stored on the other drives together with the data from the parity disk. This is done so as to be able to recalculate the elements of every file adequately and to verify the integrity of the info cloned on the new drive. This is an additional level of security for the information that you upload to your shared hosting account along with the ZFS file system that compares a special digital fingerprint for each and every file on all of the hard drives in real time.
RAID in Semi-dedicated Hosting
The data uploaded to any semi-dedicated hosting account is kept on SSD drives that work in RAID-Z. One of the drives in type of a setup is used for parity - any time data is copied on it, an additional bit is added. In case a disk happens to be flawed, it will be taken out of the RAID without disturbing the work of the websites since the data will load from the other drives, and when a brand new drive is added, the info that will be copied on it will be a mix between the info on the parity disk and data kept on the other hard disks in the RAID. That is done so as to ensure that the info that is being cloned is correct, so as soon as the new drive is rebuilt, it can be integrated into the RAID as a production one. This is one more guarantee for the integrity of your information since the ZFS file system that runs on our cloud Internet hosting platform analyzes a unique checksum of all of the copies of your files on the various drives to be able to avoid any possibility of silent data corruption.
RAID in VPS Web Hosting
The SSD drives that we use on the machines where we set up virtual private servers function in RAID to ensure that any content 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 copied on it. In case a main drive stops working, it is changed and the data which will be duplicated on it is calculated between the rest of the drives and the parity one. This is done to ensure that the required info is copied and that no file is corrupted as the new drive will be incorporated into the RAID afterwards. Also, we use hard disk drives functioning in RAID on the backup servers, so if you add this upgrade to your VPS plan, you will use an even more reliable Internet hosting service because your content will be available on multiple drives regardless of any type of unpredicted hardware malfunction.
