RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform uses for storage function in RAID-Z. This sort of RAID is created 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 located on the other drives is copied with an extra bit added to it. In case one of the disks stops functioning, your websites will continue working from the other ones and as soon as we replace the problematic one, the data that will be cloned on it will be rebuilt from what is stored on the remaining drives together with the info from the parity disk. This is done so as to be able to recalculate the bits of each and every file properly and to authenticate the integrity of the info copied on the new drive. This is another level of security for the information which you upload to your cloud hosting account in addition to the ZFS file system which analyzes a unique digital fingerprint for every single file on all the hard drives in real time.
RAID in Semi-dedicated Hosting
The information uploaded to any semi-dedicated hosting account is saved on SSD drives which operate in RAID-Z. One of the drives in type of a configuration is used for parity - every time data is cloned on it, an additional bit is added. In case a disk happens to be defective, it will be removed from the RAID without disturbing the functioning of the websites as the data will load from the remaining drives, and when a new drive is included, the information which will be duplicated on it will be a blend between the data on the parity disk and data stored on the other hard disks in the RAID. This is done to ensure that the information which is being duplicated is correct, so as soon as the new drive is rebuilt, it can be integrated into the RAID as a production one. This is an additional guarantee for the integrity of your information since the ZFS file system which runs on our cloud web hosting platform analyzes a special checksum of all copies of the files on the different drives to avoid any chance of silent data corruption.
RAID in VPS
If you employ one of our virtual private server solutions, any content that you upload will be stored on SSD drives which function in RAID. At least one drive is intended for parity so as to guarantee the integrity of your info. In simple terms, this is a special drive where data is copied with one bit added to it. In case a disk from the RAID fails, your Internet sites will continue working and when a new disk replaces the malfunctioning one, the bits of the information that will be copied on it are calculated using the healthy and the parity drives. By doing this, any potential for corrupting data throughout the process is avoided. We also use regular hard disk drives which function in RAID for storing backups, so should you include this service to your VPS plan, your site content will be stored on multiple drives and you will never have to worry about its integrity even in the event of multiple drive failures.
