RAID in Cloud Web Hosting
The SSD drives that our cutting-edge cloud Internet hosting platform employs for storage work in RAID-Z. This type of RAID is intended to work with the ZFS file system that runs on the platform and it uses the so-called parity disk - a specific drive where information saved on the other drives is copied 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 malfunctioning one, the information that will be duplicated on it will be rebuilt from what is stored on the remaining drives together with the info from the parity disk. This is performed so as to be able to recalculate the elements of each and every file adequately and to authenticate the integrity of the info copied on the new drive. This is another level of security for the content which you upload to your cloud web hosting account in addition to the ZFS file system that analyzes a unique digital fingerprint for each file on all disk drives in real time.
RAID in Semi-dedicated Hosting
The SSD drives that are used for keeping any content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a special setup where one or more disk drives are employed for parity i.e. the system will add an additional bit to any data duplicated on this type of a disk drive. If a disk fails and is substituted with another one, what information will be copied on the latter will be a mix calculated between the data on the other drives and that on the parity one. This is done to guarantee that the information on the new drive shall be accurate. Throughout the process, the RAID will continue functioning normally and the faulty drive won't impact the proper operation of your websites in any way. Using SSDs in RAID-Z is a fantastic addition to the ZFS file system that runs on our revolutionary cloud platform with respect to preserving the integrity of your files because ZFS uses specific digital identifiers called checksums so as to avoid silent data corruption.
RAID in VPS Web Hosting
The SSD drives that we use on the physical machines where we create virtual private servers work in RAID to make sure that any content which you upload will be available and intact at all times. At least a single drive is employed for parity - one bit of data is added to any data copied on it. In the event that a main drive fails, it is changed and the info which will be cloned on it is calculated between the remaining drives and the parity one. This is done to make sure that the required data is copied and that no file is corrupted because the new drive will be included in the RAID afterwards. We also use hard disk drives functioning in RAID on the backup servers, so in case you add this upgrade to your VPS package, you will use an even more reliable hosting service as your content will be available on multiple drives regardless of any sudden hardware malfunction.
