RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to employ multiple hard drives as one single logical unit. To put it differently, all the drives are used as one and the information on all of them is the same. Such a configuration has 2 key advantages over using just a single drive to save data - the first one is redundancy, so if one drive breaks down, the info will be accessible through the remaining ones, and the second is better performance because the input/output, or reading/writing operations will be spread among several drives. There are different RAID types based on the number of drives are employed, whether reading and writing are both handled from all the drives simultaneously, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etc. Based on the particular setup, the error tolerance and the performance could differ.

RAID in Cloud Web Hosting

The advanced cloud Internet hosting platform where all cloud web hosting accounts are created uses quick NVMe drives as opposed to the classic HDDs, and they function in RAID-Z. With this setup, a number of hard disks function together and at least a single one is a dedicated parity disk. Simply put, when data is written on the remaining drives, it is copied on the parity one adding an extra bit. This is done for redundancy as even if a 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 saved on the other ones, therefore practically nothing will be lost and there won't be any service disorders. This is one more level of protection for your information along with the top-notch ZFS file system which uses checksums to ensure that all data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The info uploaded to any semi-dedicated hosting account is kept on NVMe drives that operate in RAID-Z. One of the drives in type of a setup is used for parity - any time data is cloned on it, an extra bit is added. If a disk turns out to be defective, it will be taken out of the RAID without disturbing the functioning of the Internet sites since the data will load from the rest of the drives, and when a brand new drive is included, the information that will be cloned on it will be a combination between the data on the parity disk and data kept on the other hard disks in the RAID. This is done in order to ensure that the info that is being copied is correct, so once the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is an extra warranty for the integrity of your information because the ZFS file system which runs on our cloud hosting platform analyzes a special checksum of all the copies of your files on the various drives so as to avoid any chance of silent data corruption.

RAID in VPS Hosting

All virtual private server accounts which our company provides are created on physical servers which employ NVMe drives operating in RAID. At least 1 drive is intended for parity - one extra bit is added to the info duplicated on it and if a main disk stops working, this bit makes it simpler to recalculate the bits of the files on the failed disk drive so that the correct data is restored on the new drive included in the RAID. At the same time, your websites will still be online since all the info will still load from at least 1 more drive. In case you add routine backups to your VPS package, a copy of the data will be stored on standard hard disks that also function in RAID as we want to make sure that any sort of content you upload will be protected all of the time. Working with multiple drives in RAID for all of the main and backup servers permits us to offer fast and reliable Internet hosting service.
