RAID, or Redundant Array of Independent Disks, is a technology of keeping data on multiple hard drives that work together as a single logical unit. The drives could be physical or logical i.e. in the aforementioned case a single drive is split into independent ones via virtualization software. In either case, the same data is stored on all the drives and the key benefit of using this kind of a setup is that in the event that a drive breaks down, the data will remain available on the remaining ones. Employing a RAID also enhances the overall performance since the input and output operations will be spread among a number of drives. There are several types of RAID dependant upon how many hard disks are used, whether writing is carried out on all the drives in real time or just on a single one, and how the data is synchronized between the drives - whether it's written in blocks on one drive after another or it is mirrored from one on the others. These factors show that the error tolerance and the performance between the different RAID types can differ.

RAID in Cloud Website Hosting

Our state-of-the-art cloud web hosting platform where all cloud website hosting accounts are created uses super fast SSD drives rather than the traditional HDDs, and they operate in RAID-Z. With this setup, multiple hard disks operate together and at least one of them is a dedicated parity disk. Put simply, when data is written on the rest of the drives, it is cloned on the parity one adding an extra bit. This is done for redundancy as even if a drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified thanks to the parity disk and the data saved on the other ones, which means that not a single thing will be lost and there will not be any service interruptions. This is an additional level of protection for your information along with the advanced ZFS file system which uses checksums to make sure that all data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Hosting

If you host your websites in a semi-dedicated hosting account from our company, all the content which you upload will be held on SSD drives which operate in RAID-Z. With this kind of RAID, at least one of the hard drives is used for parity - when data is synced between the drives, an additional bit is added to it on the parity one. The idea behind this is to ensure the integrity of the information that is copied to a brand new drive if one of the drives in the RAID fails since the content being copied on the new disk is recalculated from the data on the standard hard drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a disk drive stops functioning, the system can switch to a different one promptly without service disturbances of any sort. RAID-Z adds an additional level of safety for the content that you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums so as to verify the integrity of each file.

RAID in VPS Hosting

All virtual private server accounts which we offer are generated on physical servers which take advantage of SSD drives functioning in RAID. At least one drive is employed for parity - one additional bit is included in the info cloned on it and if a main disk stops working, this bit makes it much simpler to recalculate the bits of the files on the damaged disk drive so that the right information is restored on the new drive added to the RAID. Meanwhile, your sites will remain online because all the info will still load from at least one other hard drive. In the event that you add regular backups to your VPS package, a copy of the info will be saved on standard hard disks which also operate in RAID as we would like to make sure that any type of site content you upload will be protected at all times. Working with multiple hard drives in RAID for all main and backup servers allows us to offer fast and reliable Internet hosting service.
