Redundant Array of Independent Disks, or RAID, is a method of saving content on a number of hard drives at the same time. A RAID can be software or hardware depending on the hard drives that are used - physical or logical ones, yet what is common between them is that they all function as just a single unit where your information is kept. The biggest advantage of using a RAID is redundancy since the information on all the drives shall be exactly the same at all times, so even in the event that some drive fails for whatever reason, the information will still be present on the remaining drives. The overall performance will also improve as the reading and writing processes will be split between various drives, so a single one will never be overloaded. There are different sorts of RAIDs where the capabilities and fault tolerance could differ depending on the particular setup - whether information is written on all drives in real time or it's written on one drive and then mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Shared Hosting

The NVMe drives that our cutting-edge cloud web 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 employs the so-called parity disk - a specific drive where data stored on the other drives is duplicated with an extra bit added to it. If one of the disks stops functioning, your websites will continue working from the other ones and as soon as we replace the problematic one, the data that will be duplicated on it will be rebuilt from what is stored on the rest of the drives together with the data 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 info copied on the new drive. This is one more level of security for the info you upload to your shared hosting account together with the ZFS file system that compares a special digital fingerprint for every single file on all the disk drives in real time.

RAID in Semi-dedicated Servers

If you host your websites inside a semi-dedicated server account from our company, all of the content that you upload will be held on NVMe drives which work in RAID-Z. With this kind of RAID, at least one of the hard disks is used for parity - when data is synchronized between the drives, an extra bit is added to it on the parity one. The reasoning behind this is to ensure the integrity of the data which is cloned to a brand new drive if one of the hard drives in the RAID stops working because the website content being copied on the new disk is recalculated from the data on the standard drives and on the parity one. Another advantage of RAID-Z is that even in case a disk drive stops functioning, the system could switch to another one promptly without service disturbances of any sort. RAID-Z adds an extra level of security for the content that you upload on our cloud Internet hosting platform in addition to the ZFS file system that uses unique checksums as a way to validate the integrity of each file.

RAID in VPS Servers

All VPS server accounts that we provide are generated on physical servers which use NVMe drives operating in RAID. At least one drive is employed for parity - one extra bit is added to the data duplicated on it and in case a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the failed drive so that the correct data is restored on the new drive included in the RAID. Meanwhile, your Internet sites will still be online because all the information will still load from at least one more disk drive. In case you add routine backups to your VPS plan, a copy of your data will be stored on standard hard disks that also work in RAID because we want to make certain that any sort of site content you upload will be safe and sound all of the time. Employing multiple hard disks in RAID for all main and backup servers permits us to offer fast and reliable web hosting service.
