RAID, or Redundant Array of Independent Disks, is a technology of keeping data on several hard disk drives that function together as one single logical unit. The drives could be physical or logical i.e. in the aforementioned case a single drive is split into separate ones via virtualization software. In any case, the same info is saved on all drives and the basic advantage of using such a setup is that in the event that a drive stops working, the data shall still be available on the other ones. Using a RAID also boosts the performance since the input and output operations will be spread among a few drives. There are several types of RAID dependant upon how many hard disks are used, whether writing is performed on all of the drives in real time or just on one, and how the data is synchronized between the hard drives - whether it is written in blocks on one drive after another or it is mirrored from one on the others. These factors imply that the fault tolerance and the performance between the different RAID types can vary.

RAID in Cloud Hosting

The NVMe drives that our cutting-edge cloud hosting platform uses for storage operate 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 information located on the other drives is copied with an extra bit added to it. If one of the disks stops functioning, your sites will continue working from the other ones and as soon as we replace the malfunctioning one, the information that will be cloned on it will be recovered from what is stored on the other drives together with the information from the parity disk. This is done so as to be able to recalculate the elements of every file correctly and to validate 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 together with 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 NVMe drives that are used for storing any website content uploaded to the semi-dedicated hosting accounts that we provide function in RAID-Z. This is a special configuration where one or more drives are employed for parity i.e. the system will include an extra bit to any data duplicated on this type of a hard drive. If a disk fails and is substituted with a new one, what data will be copied on the latter will be a combination calculated between the data on the other disks and that on the parity one. This is done to ensure that the information on the new drive shall be correct. Throughout the procedure, the RAID will continue working adequately and the problematic drive won't impact the adequate operation of your Internet sites in any respect. Using NVMes in RAID-Z is an outstanding addition to the ZFS file system that runs on our cutting-edge cloud platform with regards to preserving the integrity of your files because ZFS uses special digital identifiers called checksums so as to avoid silent data corruption.

RAID in VPS Hosting

In case you take advantage of one of our virtual private server solutions, any content that you upload will be kept on NVMe drives that work in RAID. At least a single drive is used for parity to guarantee the integrity of your information. In simple terms, this is a special drive where info is copied with one bit added to it. In the event that a disk part of the RAID stops working, your Internet sites will continue working and when a new disk replaces the malfunctioning one, the bits of the info that will be cloned on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is averted. We also employ standard hard drives which function in RAID for storing backup copies, so if you add this service to your VPS package, your content will be kept on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive breakdowns.
