RAID in Hosting
The SSD drives that our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This kind of RAID is created to work with the ZFS file system that runs on the platform and it uses the so-called parity disk - a specific drive where info stored on the other drives is duplicated with an additional bit added to it. In the event that one of the disks fails, your Internet sites will continue working from the other ones and once we replace the faulty one, the info which will be cloned on it will be rebuilt from what is stored on the rest of the drives together with the information from the parity disk. This is done in order to be able to recalculate the bits of every file properly and to validate the integrity of the data duplicated on the new drive. This is one more level of security for the content which you upload to your hosting account together with the ZFS file system which analyzes a unique digital fingerprint for each and every file on all of the disk drives in real time.
RAID in Semi-dedicated Servers
The SSD drives which are used for saving any website content uploaded to the semi-dedicated server accounts which we offer work in RAID-Z. This is a specific configuration where one or more disk drives are used for parity i.e. the system will include an extra bit to any data copied on this kind of a disk drive. In the event that a disk fails and is replaced with another one, what data will be copied on the latter will be a combination calculated between the data on the remaining hard disks and that on the parity one. This is done to ensure that the data on the new drive will be correct. Throughout the procedure, the RAID will continue functioning adequately and the faulty drive will not have an effect on the proper operation of your websites in any way. Working with SSDs in RAID-Z is an amazing addition to the ZFS file system that runs on our revolutionary cloud platform with regard to preserving the integrity of your files since ZFS uses special digital identifiers named checksums to avoid silent data corruption.
RAID in VPS Servers
The SSD drives which we use on the machines where we create VPS servers work in RAID to make sure that any content that you upload will be available and intact all the time. At least one drive is employed for parity - one bit of information is added to any data copied on it. In the event that a main drive stops working, it is changed and the data that will be copied on it is calculated between the remaining drives and the parity one. That’s done to ensure that the needed data is copied and that not a single file is corrupted as the new drive will be incorporated into the RAID afterwards. We also use hard disk drives operating in RAID on the backup servers, so if you add this upgrade to your VPS plan, you shall use an even more reliable Internet hosting service because your content will be available on multiple drives regardless of any kind of unpredicted hardware malfunction.
