RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that permits a system to take advantage of many 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 kind of a configuration has 2 major advantages over using just a single drive to save data - the first is redundancy, so in case one drive fails, the data will be accessible from the others, and the second is improved performance because the input/output, or reading/writing operations will be spread among different drives. There are different RAID types based on what number of drives are used, whether reading and writing are both done from all drives simultaneously, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Determined by the particular setup, the fault tolerance and the performance may differ.

RAID in Cloud Hosting

The NVMe drives that our cutting-edge cloud hosting platform uses for storage work in RAID-Z. This sort of RAID is intended to work with the ZFS file system that runs on the platform and it uses the so-called parity disk - a special drive where info located on the other drives is cloned with an additional bit added to it. In case one of the disks stops functioning, your sites will continue working from the other ones and after we replace the problematic one, the data which will be copied on it will be recovered from what is stored on the other drives together with the data from the parity disk. This is performed in order to be able to recalculate the elements of every file correctly and to confirm the integrity of the information duplicated on the new drive. This is an additional level of security for the information which you upload to your cloud hosting account together with the ZFS file system which analyzes a unique digital fingerprint for each and every file on all hard drives in real time.

RAID in Semi-dedicated Hosting

The information uploaded to any semi-dedicated hosting account is stored on NVMe drives which work in RAID-Z. One of the drives in type of a setup is used for parity - each time data is cloned on it, an additional bit is added. In case a disk happens to be faulty, it will be taken out of the RAID without interrupting the functioning of the sites as the data will load from the rest of the drives, and when a new drive is added, the data that will be duplicated on it will be a blend between the info on the parity disk and data saved on the other hard drives in the RAID. That is done in order to guarantee that the info which is being copied is correct, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is an additional guarantee for the integrity of your info as the ZFS file system which runs on our cloud Internet hosting platform compares a unique checksum of all the copies of your files on the separate drives to be able to avoid any possibility of silent data corruption.

RAID in VPS Hosting

All virtual private server accounts that our company provides are created on physical servers that employ NVMe drives working in RAID. At least one drive is intended for parity - one additional bit is included in the data copied on it and in case a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the accurate info is restored on the new drive included in the RAID. At the same time, your Internet sites will still be online as all the information will still load from at least 1 more disk drive. In the event that you add routine backups to your VPS plan, a copy of your info will be stored on standard hard disks which also function in RAID since we would like to make sure that any type of website content you add will be safe and sound all of the time. Employing multiple hard drives in RAID for all main and backup servers enables us to offer fast and reliable hosting service.
