RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that allows a system to employ multiple hard drives as a single logical unit. Simply put, all of the drives are used as one and the information on all of them is the same. This type of a configuration has two huge advantages over using a single drive to save data - the first is redundancy, so in the event that one drive fails, the info will be accessed from the others, and the second one is improved performance as the input/output, or reading/writing operations will be distributed among multiple drives. There're different RAID types based on what number of drives are used, if reading and writing are both executed from all of the drives simultaneously, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etc. Depending on the exact setup, the error tolerance and the performance vary.

RAID in Cloud Hosting

All of the content which you upload to your new cloud hosting account will be held on quick SSD drives that function in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of security for your website content on top of the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the data is saved on several disks and at least 1 is a parity disk - whenever info is written on it, an extra bit is added, so in case any drive fails for whatever reason, the integrity of the data can be verified by recalculating its bits in accordance with what is stored on the production hard disks 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 problematic drive is replaced and the info is synchronized on it.

RAID in Semi-dedicated Hosting

The RAID type which we employ for the cloud hosting platform where your semi-dedicated hosting account will be created is known as RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. Simply put, whenever any kind of data is duplicated on this particular drive, one more bit is added to it and if a problematic disk is replaced, the information which will be cloned on it is a mix of the data on the remaining drives in the RAID and that on the parity one. We do this to make sure that your info is intact. During this process, your websites will be up and running normally as RAID-Z allows for a whole drive to fail without causing any service disruptions and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to warrant that no data shall get silently corrupted on our servers, you'll never need to worry about the integrity of your files.

RAID in VPS Hosting

In case you employ one of our virtual private server packages, any content you upload will be stored on SSD drives which function in RAID. At least one drive is used for parity so as to guarantee the integrity of your information. In simple terms, this is a special drive where data is copied with one bit added to it. In case a disk in the RAID breaks down, your sites will continue working and when a new disk substitutes the flawed one, the bits of the data that will be duplicated on it are calculated by using the healthy and the parity drives. This way, any possibility of corrupting data throughout the process is averted. We also use conventional hard disks which work in RAID for storing backups, so should you include this service to your VPS package, your site content will be kept on multiple drives and you will never need to worry about its integrity even in the event of multiple drive breakdowns.
