Redundant Array of Independent Disks, or RAID, is a way of storing content on several hard disk drives at the same time. A RAID might be software or hardware based on the hard drives that are used - physical or logical ones, however what’s common between them is the fact that they all perform as just one single unit where data is stored. The top advantage of using a RAID is redundancy since the data on all of the drives shall be exactly the same at all times, so even if a drive fails for whatever reason, the info will still be available on the other drives. The general performance is enhanced as well because the reading and writing processes could be split between multiple drives, so a single one won't be overloaded. There're different types of RAIDs where the capabilities and fault tolerance may vary depending on the specific setup - whether information is written on all drives real-time or it is written on one drive and afterwards mirrored on another, what amount of drives are used for the RAID, and many others.

RAID in Cloud Website Hosting

All of the content that you upload to your new cloud website hosting account will be placed on fast NVMe drives which function in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud web hosting platform and it adds an additional level of security for your site content on top of the real-time checksum verification that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least one 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 saved on the production hard drives and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue working efficiently until the problematic drive is replaced and the info is synchronized on it.

RAID in Semi-dedicated Servers

In case you host your sites within a semi-dedicated server account from our company, any content which you upload will be kept on NVMe drives that work in RAID-Z. With this kind of RAID, at least one of the hard drives is used for parity - when data is synchronized between the disks, an additional bit is included in it on the parity one. The purpose behind this is to guarantee the integrity of the info which is copied to a new drive in the event that one of the disks in the RAID fails because the website content being copied on the brand new disk is recalculated from the data on the standard hard drives and on the parity one. An additional advantage of RAID-Z is that even in case a drive fails, the system can easily switch to another one quickly without service interruptions of any sort. RAID-Z adds an additional level of security for the content you upload on our cloud Internet hosting platform together with the ZFS file system which uses unique checksums in order to validate the integrity of every single file.

RAID in VPS Servers

All VPS server accounts that we provide are created on physical servers which take advantage of NVMe drives operating in RAID. At least one drive is used for parity - one extra bit is included in the information cloned on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged disk drive so that the correct data is restored on the new drive included in the RAID. At the same time, your websites will still be online because all the data will still load from at least 1 more 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 that also work in RAID because we want to make sure that any type of website content you add will be risk-free all the time. Working with multiple drives in RAID for all of the main and backup servers permits us to offer fast and reliable web hosting service.
