RAID, or Redundant Array of Independent Disks, is a technology of keeping data on several hard disk drives which operate together as one single logical unit. The drives could be physical or logical i.e. in the second case a single drive is split into individual ones via virtualization software. In any case, the very same info is stored on all of the drives and the key benefit of employing this type of a setup is that in case a drive stops working, the data shall still be available on the other ones. Using a RAID also boosts the performance as the input and output operations will be spread among a few drives. There are several kinds of RAID based on how many hard drives are used, whether writing is done on all drives in real time or just on one, and how the information is synchronized between the drives - whether it is recorded in blocks on one drive after another or all of it is mirrored from one on the others. All of these factors show that the fault tolerance and the performance between the different RAID types 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 operate in RAID-Z. This setup is built to work with the ZFS file system which runs on our cloud hosting platform and it adds one more level of security for your site content in addition to the real-time checksum validation which ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least 1 is a parity disk - whenever info is written on it, an additional bit is added, so in the event that any drive fails for some reason, the stability of the info can be verified by recalculating its bits in accordance with what is saved on the production drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue operating effectively until the faulty drive is changed and the information is synchronized on it.

RAID in Semi-dedicated Servers

The RAID type which we employ for the cloud hosting platform where your semi-dedicated server account shall be created is referred to as RAID-Z. What is different about it is that at least one 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 included to it and in the event that a problematic disk is replaced, the information that will be copied on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. This is done to guarantee that your info is intact. Throughout this process, your websites will be working normally as RAID-Z enables an entire drive to fail without any service disruptions and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to guarantee that no data will get silently corrupted on our servers, you'll never have to worry about the integrity of your files.

RAID in VPS Servers

All VPS server accounts that our company provides are made on physical servers which take advantage of NVMe drives functioning in RAID. At least one drive is intended for parity - one additional bit is included in the information copied on it and in case a main disk fails, this bit makes it much easier to recalculate the bits of the files on the failed drive so that the right info is restored on the new drive included in the RAID. In the mean time, your Internet sites will stay online because all the data will still load from at least 1 more hard drive. In case you add routine backups to your VPS package, a copy of your information will be kept on standard disk drives which also work in RAID because we want to make sure that any content you upload will be risk-free all of the time. Working with multiple drives in RAID for all main and backup servers permits us to offer fast and reliable hosting service.
