Redundant Array of Independent Disks, or RAID, is a way of saving content on several hard disks at the same time. A RAID could be software or hardware depending on the hard drives that are used - physical or logical ones, however what is common between them is the fact that they all work as a single unit where info is kept. The main advantage of employing a RAID is redundancy as the info on all drives is identical at all times, so even if one of the drives fails for some reason, the data will still be available on the rest of the drives. The overall performance is also better since the reading and writing processes will be split between multiple drives, so a single one will not be overloaded. There're different sorts of RAIDs where the efficiency and fault tolerance can vary based on the exact setup - whether your data is written on all of the drives in real time or it's written on a single drive and after that mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Hosting

All the content which you upload to your new hosting account will be saved on quick NVMe drives that function in RAID-Z. This setup is built to use the ZFS file system which runs on our cloud Internet hosting platform and it adds another level of protection for your site content in addition to the real-time checksum verification that ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is stored on a couple of disks and at least 1 is a parity disk - whenever info is written on it, an additional bit is added, so in case any drive fails for some reason, the stability of the information can be verified by recalculating its bits in accordance with what is saved 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 functioning effectively until the faulty drive is replaced and the information is synchronized on it.

RAID in Semi-dedicated Hosting

The NVMe drives that are used for holding any content uploaded to the semi-dedicated hosting accounts that we offer operate in RAID-Z. This is a special setup where one or more disk drives are used for parity i.e. the system will add an extra bit to any data duplicated on such a hard drive. In case that a disk fails and is replaced with another one, what info will be duplicated on the latter will be a combination calculated between the data on the remaining disks and that on the parity one. This is done to ensure that the info on the new drive shall be correct. During the procedure, the RAID will continue functioning adequately and the malfunctioning drive will not impact the adequate operation of your Internet sites by any means. Working with NVMes in RAID-Z is a superb addition to the ZFS file system that runs on our cutting-edge cloud platform with regard to preserving the integrity of your files as ZFS uses specific digital identifiers referred to as checksums in order to avoid silent data corruption.

RAID in VPS Web Hosting

The physical servers where we make virtual private server work with quick NVMe drives that will raise the speed of your websites considerably. The hard disks work in RAID to ensure that you won't lose any info as a result of a power loss or a hardware failure. The production servers take advantage of a variety of drives where the information is stored and one disk is used for parity i.e. one bit is added to all information copied on it, which makes it much easier to restore the site content without any loss if a main drive stops working. If you choose our backup service, your information will be kept on a separate machine which uses standard hard-disk drives and despite the fact that there is no parity one in this case, they are also in a RAID to make sure that we will have a backup of your content all of the time. With this type of configuration your info will always be safe as it will be available on multiple disk drives.
