Redundant Array of Independent Disks, or RAID, is a way of keeping content on a number of hard disks simultaneously. A RAID might be software or hardware depending on the HDDs which are used - physical or logical ones, however what’s common between them is the fact that they all operate as one single unit where information is stored. The biggest advantage of using a RAID is redundancy since the information on all drives is exactly the same all the time, so even if some drive fails for whatever reason, the info will still be available on the other drives. The general performance will also improve since the reading and writing processes will be split between different drives, so a single one can't be overloaded. There're different sorts of RAIDs where the performance and fault tolerance may differ based on the specific setup - whether info is written on all of the drives in real time or it is written on one drive and afterwards mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Shared Hosting

All content which you upload to your new shared hosting account will be stored on fast NVMe drives which work in RAID-Z. This configuration is built to employ the ZFS file system which runs on our cloud Internet hosting platform and it adds an additional level of security for your site content on top of the real-time checksum verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the information is saved on several disks and at least one of them is a parity disk - whenever information is recorded on it, an additional bit is added, so if any drive fails for some reason, the integrity of the information can be verified by recalculating its bits in accordance with what is stored on the production disks and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it will continue working flawlessly until the malfunctioning drive is replaced and the info is synchronized on it.

RAID in Semi-dedicated Hosting

The NVMe drives which are used for storing any content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a specific configuration where one or more disk drives are employed for parity i.e. the system will add an extra bit to any data copied on such a drive. In the event that a disk fails and is replaced with a new one, what data will be copied on the latter will be a mix calculated between the data on the remaining hard disks and that on the parity one. This is done to ensure that the info on the new drive will be accurate. During the process, the RAID will continue functioning adequately and the problematic drive will not impact the proper operation of your Internet sites by any means. Working with NVMes in RAID-Z is an amazing addition to the ZFS file system which runs on our cutting-edge cloud platform with respect to preserving the integrity of your files because ZFS uses specific digital identifiers known as checksums so as to avoid silent data corruption.

RAID in VPS Hosting

If you employ one of our virtual private server packages, any content that you upload will be saved on NVMe drives which 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 data is copied with one bit added to it. If a disk from the RAID fails, your websites will continue working and when a new disk substitutes the defective one, the bits of the info that will be copied on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is prevented. We also employ standard hard disk drives which work in RAID for storing backups, so if you include this service to your VPS package, your content will be stored on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
