RAID in Cloud Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform employs for storage operate 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 saved on the other drives is copied with an extra bit added to it. In case one of the disks stops working, your Internet sites will continue working from the other ones and as soon as we replace the problematic one, the data that will be copied on it will be recovered from what is stored on the rest of the drives along with the data 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 another level of security for the information that you upload to your cloud hosting account in addition to the ZFS file system which analyzes a unique digital fingerprint for each file on all of the disk drives in real time.
RAID in Semi-dedicated Hosting
The data 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 configuration is used for parity - every time data is copied on it, an extra bit is added. If a disk turns out to be faulty, it will be removed from the RAID without disturbing the work of the sites as the data will load from the remaining drives, and when a brand new drive is included, the data that will be cloned on it will be a mix between the information on the parity disk and data stored on the other hard drives in the RAID. That is done in order to guarantee that the info which is being duplicated is accurate, so as soon as the new drive is rebuilt, it could be integrated into the RAID as a production one. This is one more warranty for the integrity of your info since the ZFS file system that runs on our cloud Internet hosting platform analyzes a unique checksum of all copies of your files on the various drives in order to avoid any chance of silent data corruption.
RAID in VPS Web Hosting
In case you employ one of our virtual private server solutions, any content that you upload will be stored on SSD drives which operate in RAID. At least one drive is intended for parity to guarantee the integrity of the info. In simple terms, this is a special drive where information is copied with one bit added to it. In case a disk from the RAID stops functioning, your sites will continue working and when a new disk takes the place of the flawed one, the bits of the information that will be duplicated on it are calculated using the healthy and the parity drives. This way, any probability of corrupting data throughout the process is averted. We also employ regular hard disks which operate in RAID for storing backup copies, so if you include this service to your VPS package, your content will be kept on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive failures.
