RAID, or Redundant Array of Independent Disks, is a technology of keeping data on several hard disk drives that work together as one logical unit. The drives could be physical or logical i.e. in the aforementioned case a single drive is split into individual ones using virtualization software. Either way, exactly the same data is kept on all of the drives and the main benefit of using this kind of a setup is that in the event that a drive stops working, the data will remain available on the other ones. Having a RAID also improves the performance since the input and output operations will be spread among a number of drives. There are several kinds of RAID depending on how many drives are used, whether writing is done on all the drives in real time or just on one, and how the info is synced between the hard drives - whether it is written in blocks on one drive after another or it is mirrored from one on the others. These factors show that the error tolerance as well as the performance between the various RAID types can differ.

RAID in Cloud Website Hosting

The hard disks which we employ for storage with our state-of-the-art cloud hosting platform are not the classic HDDs, but high-speed NVMes. They operate in RAID-Z - a special setup intended for the ZFS file system which we use. All the content that you upload to the cloud website hosting account will be stored on multiple disk drives and at least 1 shall be used as a parity disk. This is a specific drive where an additional bit is included to any content copied on it. In case a disk in the RAID stops working, it'll be changed without any service disturbances and the information will be recovered on the new drive by recalculating its bits using the data on the parity disk along with that on the remaining disks. This is done so as to ensure the integrity of the info and along with the real-time checksum authentication which the ZFS file system performs on all drives, you won't ever need to be concerned about the loss of any information no matter what.

RAID in Semi-dedicated Hosting

The NVMe drives that are used for storing any website content uploaded to the semi-dedicated hosting accounts which we offer work in RAID-Z. This is a specific configuration where one or more disk drives are used for parity i.e. the system will add an additional bit to any data duplicated on such a drive. If a disk fails and is substituted with a new one, what info will be copied on the latter shall 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 data on the new drive will be correct. Throughout the process, the RAID will continue operating adequately and the malfunctioning drive won't affect the normal operation of your Internet sites in any respect. Working with NVMes in RAID-Z is an excellent addition to the ZFS file system that runs on our top-notch cloud platform in terms of preserving the integrity of your files because ZFS uses specific digital identifiers referred to as checksums to prevent silent data corruption.

RAID in VPS Web Hosting

If you employ one of our virtual private server solutions, any content which you upload will be kept on NVMe drives that work in RAID. At least a single drive is used for parity to guarantee the integrity of your info. In simple terms, this is a special drive where information is copied with one bit added to it. If a disk inside the RAID stops working, your sites will continue working and when a new disk takes the place of the faulty one, the bits of the data that will be duplicated on it are calculated using the healthy and the parity drives. By doing this, any possibility of corrupting data throughout the process is avoided. We also use regular hard disks that work in RAID for storing backup copies, so in case you include this service to your VPS plan, your content will be saved on multiple drives and you will never need to worry about its integrity even in the event of multiple drive breakdowns.
