RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to take advantage of several hard drives as one single logical unit. Simply put, all of the drives are used as one and the data on all of them is the same. Such a setup has two huge advantages over using just a single drive to store data - the first one is redundancy, so if one drive breaks down, the info will be accessed from the remaining ones, and the second one is improved performance since the input/output, or reading/writing operations will be spread among different drives. You can find different RAID types based on the number of drives are used, whether reading and writing are both done from all drives simultaneously, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Based on the exact setup, the fault tolerance and the performance may vary.

RAID in Hosting

All the content that you upload to your new hosting account will be saved on fast NVMe drives that work in RAID-Z. This configuration is built to employ the ZFS file system which runs on our cloud Internet hosting platform and it adds an additional level of security for your website 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 1 is a parity disk - whenever data is recorded on it, an additional bit is added, so in the event that any drive stops working for whatever reason, the integrity of the info can be verified by recalculating its bits in accordance with what is kept on the production disks and on the parity one. With RAID-Z, the operation of our system won't be interrupted and it will continue operating smoothly until the faulty drive is changed and the information is synced on it.

RAID in Semi-dedicated Hosting

The RAID type which we employ for the cloud web hosting platform where your semi-dedicated hosting account shall be created is known as RAID-Z. What is different about it is that at least 1 of the disks is employed as a parity drive. In simple terms, whenever any kind of data is cloned on this specific hard drive, one more bit is included to it and in case a problematic disk is replaced, the information which will be cloned on it is a combination of the data on the remaining hard drives in the RAID and that on the parity one. We do this to make sure that your information is intact. During this process, your websites will be working normally because RAID-Z makes it possible for an entire drive to fail without causing any service interruptions and it simply works by using one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to guarantee 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 Web Hosting

All virtual private server accounts that we offer are made on physical servers which use NVMe drives working in RAID. At least one drive is intended for parity - one additional bit is added to the information duplicated on it and in case a main disk stops working, this bit makes it much easier to recalculate the bits of the files on the failed drive so that the accurate data is restored on the new drive included in the RAID. In the mean time, your Internet sites will stay online as all the info will still load from at least 1 other disk drive. If you add regular backups to your VPS package, a copy of your info will be kept on standard disk drives which also work in RAID since we would like to make sure that any type of content you add will be safe and sound at all times. Employing multiple hard drives in RAID for all the main and backup servers enables us to offer fast and reliable Internet hosting service.
