RAID
What's RAID? How exactly does RAID work? Become aware of the benefits of employing a RAID-equipped server.
Redundant Array of Independent Disks, or RAID, is a method of storing content on a number of hard drives at the same time. A RAID might be software or hardware based on the HDDs that are used - physical or logical ones, but what’s common between them is that they all work as just a single unit where your information is kept. The top advantage of using a RAID is redundancy because the data on all the drives is exactly the same all the time, so even if one of the drives fails for some reason, the information will still be available on the remaining drives. The overall performance is enhanced as well as the reading and writing processes will be split between multiple drives, so a single one will not be overloaded. There're different kinds of RAIDs where the effectiveness and fault tolerance may vary depending on the exact setup - whether information is written on all of the drives real-time or it's written on a single drive and then mirrored on another, the number of drives are used for the RAID, and so on.

RAID in Shared Web Hosting
The cutting-edge cloud hosting platform where all
shared web hosting accounts are made uses quick NVMe drives instead of the standard HDDs, and they function in RAID-Z. With this setup, several hard disk drives function together and at least 1 is a dedicated parity disk. Put simply, when data is written on the other drives, it is copied on the parity one adding an extra bit. This is performed for redundancy as even in case some drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, therefore absolutely nothing will be lost and there won't be any service interruptions. This is an additional level of security for your data along with the revolutionary ZFS file system which uses checksums to ensure that all the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Servers
The NVMe drives that are used for saving any website content uploaded to the
semi-dedicated server accounts that we offer operate in RAID-Z. This is a specific configuration where one or more hard drives are used for parity i.e. the system will add an additional bit to any data copied on such a disk drive. If a disk fails and is replaced with a new one, what information will be duplicated on the latter shall be a mix calculated between the data on the other hard disks and that on the parity one. This is done to make sure that the data on the new drive will be accurate. During the procedure, the RAID will continue operating adequately and the malfunctioning drive will not have an effect on the adequate operation of your websites by any means. Using NVMes in RAID-Z is an impressive addition to the ZFS file system that runs on our advanced cloud platform with respect to preserving the integrity of your files since ZFS uses specific digital identifiers referred to as checksums in order to avoid silent data corruption.

RAID in VPS Servers
All
VPS server accounts that we offer are generated on physical servers which use NVMe drives operating in RAID. At least one drive is intended for parity - one additional bit is added to the information cloned on it and if a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the correct information is recovered on the new drive added to the RAID. Meanwhile, your Internet sites will remain online as all the data will still load from at least one more hard disk. In the event that you add regular backups to your VPS plan, a copy of the information will be saved on standard hard disks which also function in RAID since we want to make certain that any kind of site content you add will be safe and sound at all times. Using multiple hard drives in RAID for all of the main and backup servers permits us to offer fast and reliable Internet hosting service.
