RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that permits a system to use a number of hard drives as a single logical unit. Simply put, all drives are used as one and the info on all of them is the same. This type of a setup has 2 key advantages over using a single drive to keep data - the first is redundancy, so in the event that one drive doesn't work, the info will be accessed from the remaining ones, and the second is better performance since the input/output, or reading/writing operations will be distributed among several drives. There're different RAID types in accordance with what number of drives are employed, if reading and writing are both done from all drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and so on. Based on the exact setup, the fault tolerance and the performance could differ.

RAID in Cloud Website Hosting

All content which you upload to your new cloud website hosting account will be saved on quick NVMe drives which function in RAID-Z. This setup is built to employ the ZFS file system that runs on our cloud Internet hosting platform and it adds one more level of security for your site content in addition to the real-time checksum authentication that ZFS uses to ensure the integrity of the data. With RAID-Z, the data is saved on a number of disks and at least one of them is a parity disk - whenever info is recorded on it, an additional bit is added, so in the event that any drive fails for whatever reason, the stability of the data can be verified by recalculating its bits based on what is stored on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue working flawlessly until the malfunctioning drive is replaced and the data is synced on it.

RAID in Semi-dedicated Servers

If you host your sites within a semi-dedicated server account from our firm, all the content that you upload will be held on NVMe drives that work in RAID-Z. With this type of RAID, at least one of the drives is used for parity - when data is synchronized between the disks, an extra 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 if one of the disks in the RAID fails as the site content being copied on the brand new disk is recalculated from the information on the standard drives and on the parity one. Another advantage of RAID-Z is the fact that even if a hard drive fails, the system could switch to a different one quickly without service disturbances of any type. RAID-Z adds an extra level of protection for the content which you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums so as to validate the integrity of every single file.

RAID in VPS Servers

The physical servers where we create VPS server work with high-speed NVMe drives which will increase the speed of your websites noticeably. The drives work in RAID to make sure that you will not lose any info as a result of a power loss or a hardware breakdown. The production servers take advantage of multiple drives where the information is stored and one disk is used for parity i.e. one bit is added to all of the info copied on it, that makes it easier to restore the content without any loss if a main drive stops working. If you use our backup service, your data will be saved on an individual machine that 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 ensure that we will have a backup copy of your website content all of the time. With this type of setup your data will always be safe since it will be available on a lot of drives.
