RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that permits a system to take advantage of many hard drives as a single logical unit. In other words, all of the drives are used as one and the data on all of them is identical. This kind of a setup has 2 major advantages over using a single drive to keep data - the first is redundancy, so in the event that one drive stops working, the info will be accessible through the others, and the second one is better performance as the input/output, or reading/writing operations will be distributed among multiple drives. You can find different RAID types based on the number of drives are used, whether reading and writing are both performed from all the drives simultaneously, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and so on. According to the exact setup, the fault tolerance and the performance may vary.

RAID in Shared Web Hosting

Any content that you upload to your new shared web hosting account will be stored on quick NVMe drives that work in RAID-Z. This setup is built to employ the ZFS file system that runs on our cloud web hosting platform and it adds another level of security for your site content on top of the real-time checksum verification which ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on a couple of disks and at least 1 is a parity disk - whenever information is recorded on it, an extra bit is added, so in case any drive fails for whatever reason, the integrity of the information can be verified by recalculating its bits in accordance with what is kept on the production hard disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating efficiently until the malfunctioning drive is changed and the info is synchronized on it.

RAID in Semi-dedicated Hosting

The NVMe drives that are used for saving any website content uploaded to the semi-dedicated hosting accounts that we provide function in RAID-Z. This is a special setup where one or more hard drives are used for parity i.e. the system will include an additional bit to any data duplicated on such a drive. In the event that a disk fails and is replaced with another one, what information will be copied on the latter shall 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. During the procedure, the RAID will continue operating adequately and the faulty drive will not have an impact on the adequate operation of your websites in any way. Using NVMes in RAID-Z is a great addition to the ZFS file system that runs on our state-of-the-art cloud platform with regard to preserving the integrity of your files because ZFS uses special digital identifiers called checksums in order to prevent silent data corruption.

RAID in VPS

All virtual private server accounts that our company offers are generated on physical servers that use NVMe drives operating in RAID. At least 1 drive is employed for parity - one extra bit is included in the data copied on it and if a main disk stops working, this bit makes it simpler to recalculate the bits of the files on the failed disk drive so that the correct info is restored on the new drive included in the RAID. Meanwhile, your sites will stay online as all the info will still load from at least one other drive. In the event that you add routine backups to your VPS package, a copy of the info will be kept on standard hard drives which also function in RAID since we want to make sure that any content you upload will be risk-free at all times. Using multiple hard disks in RAID for all main and backup servers permits us to offer fast and reliable hosting service.
