RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that makes it possible for a system to take advantage of a number of hard drives as a single logical unit. In other words, all drives are used as one and the information on all of them is the same. This type of a configuration has two major advantages over using just a single drive to save data - the first is redundancy, so if one drive stops working, the data will be accessible from the remaining ones, and the second is better performance because the input/output, or reading/writing operations will be distributed among several drives. You can find different RAID types in accordance with the number of drives are used, whether reading and writing are both done from all the drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Depending on the particular setup, the error tolerance and the performance may differ.

RAID in Cloud Website Hosting

Our revolutionary cloud web hosting platform where all cloud website hosting accounts are made employs super fast NVMe drives rather than the traditional HDDs, and they operate in RAID-Z. With this configuration, numerous hard disks work together and at least one is a dedicated parity disk. Put simply, when data is written on the remaining drives, it's copied on the parity one adding an extra bit. This is carried out for redundancy as even in case some drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, which means that not a thing will be lost and there will be no service disorders. This is another level of security for your data together with the cutting-edge ZFS file system that uses checksums to make sure that all the data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Hosting

The data uploaded to any semi-dedicated hosting account is kept on NVMe drives which work in RAID-Z. One of the drives in this kind of a configuration is used for parity - each time data is cloned on it, an extra bit is added. If a disk happens to be problematic, it will be removed from the RAID without disturbing the work of the sites since the data will load from the rest of the drives, and when a brand new drive is included, the data that will be copied on it will be a blend between the information on the parity disk and data stored on the other hard drives in the RAID. That is done so as to ensure that the data that is being cloned is correct, so once the new drive is rebuilt, it can be included in the RAID as a production one. This is one more warranty for the integrity of your information as the ZFS file system that runs on our cloud Internet hosting platform analyzes a special checksum of all of the copies of your files on the various drives so as to avoid any probability of silent data corruption.

RAID in VPS Web Hosting

All virtual private server accounts which our company offers are created on physical servers that take advantage of NVMe drives functioning in RAID. At least 1 drive is used for parity - one extra bit is added to the data cloned on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the failed disk drive so that the correct data is recovered on the new drive included in the RAID. At the same time, your websites will still be online because all the info will still load from at least 1 more hard disk. If you add routine backups to your VPS plan, a copy of your info will be saved on standard hard disks which also work in RAID since we want to make certain that any site content you upload will be protected all the time. Employing multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
