RAID, which is an acronym of Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to use many hard drives as a single logical unit. To put it differently, all the drives are used as one and the info on all of them is identical. Such a configuration has two key advantages over using just a single drive to keep data - the first is redundancy, so in case one drive fails, the information will be accessible from the others, and the second is improved performance as the input/output, or reading/writing operations will be distributed among multiple drives. There're different RAID types based on the number of drives are used, whether reading and writing are both executed from all drives concurrently, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. According to the exact setup, the error tolerance and the performance may differ.

RAID in Hosting

All content that you upload to your new hosting account will be held on quick SSD drives which function in RAID-Z. This configuration is built to employ the ZFS file system that runs on our cloud web hosting platform and it adds an additional level of protection for your content on top of the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is saved on a couple of disks and at least 1 is a parity disk - whenever info is recorded on it, an additional bit is added, so in case any drive stops functioning for some reason, the stability of the data can be verified by recalculating its bits based on what is kept on the production hard drives and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it'll continue functioning smoothly until the malfunctioning drive is replaced and the info is synced on it.

RAID in Semi-dedicated Hosting

The SSD drives that are used for holding any website content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a specific configuration where one or more disk drives are employed for parity i.e. the system will include an extra bit to any data copied on this kind of a drive. In the event that a disk fails and is replaced with another one, what information will be duplicated on the latter will be a combination calculated between the data on the other drives and that on the parity one. This is done to make sure that the information on the new drive will be accurate. During the procedure, the RAID will continue operating adequately and the faulty drive will not have an impact on the adequate operation of your sites in any respect. Working with SSDs in RAID-Z is an impressive addition to the ZFS file system which runs on our top-notch cloud platform with respect to preserving the integrity of your files because ZFS uses special digital identifiers identified as checksums in order to prevent silent data corruption.

RAID in VPS Web Hosting

All virtual private server accounts which we offer are created on physical servers which use SSD drives functioning in RAID. At least 1 drive is used for parity - one extra bit is added to the information cloned on it and if a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the right information is recovered on the new drive added to the RAID. Meanwhile, your Internet sites will remain online since all the info will still load from at least 1 other disk drive. If you add routine backups to your VPS package, a copy of the data will be stored on standard hard drives that also operate in RAID since we would like to make sure that any type of website content you add will be safe and sound all the time. Using multiple hard drives in RAID for all of the main and backup servers enables us to offer fast and reliable Internet hosting service.
