RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to use a number of hard drives as one single logical unit. Simply put, all of the drives are used as one and the information on all of them is identical. This type of a setup has 2 key advantages over using just a single drive to store data - the first is redundancy, so in the event that one drive doesn't work, the info will be accessed from the others, and the second one is improved performance since the input/output, or reading/writing operations will be spread among a number of drives. You can find different RAID types based on how many drives are employed, if reading and writing are both done from all of the drives at the same time, 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 Hosting

The revolutionary cloud Internet hosting platform where all cloud hosting accounts are generated employs fast SSD drives as an alternative to the classic HDDs, and they work in RAID-Z. With this setup, several hard disk drives operate together and at least one of them is a dedicated parity disk. In simple terms, when data is written on the other drives, it is duplicated on the parity one adding an extra bit. This is done for redundancy as even in case a drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, thus absolutely nothing will be lost and there will not be any service disorders. This is an additional level of protection for your data along with the cutting-edge ZFS file system that uses checksums to ensure that all of the data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Servers

If you host your sites within a semi-dedicated server account from our firm, all of the content which you upload will be kept on SSD drives which work in RAID-Z. With this kind of RAID, at least 1 of the hard disks is used for parity - when data is synchronized between the disks, an additional bit is added to it on the parity one. The idea behind this is to guarantee the integrity of the information which is duplicated to a brand new drive in the event that one of the drives in the RAID fails as the website content being copied on the new disk is recalculated from the data on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even in case a disk drive stops working, the system could switch to another one instantly without service interruptions of any type. RAID-Z adds an additional level of safety for the content that you upload on our cloud Internet hosting platform together with the ZFS file system that uses unique checksums in order to verify the integrity of every single file.

RAID in VPS Servers

All VPS server accounts which we offer are made on physical servers that take advantage of SSD drives working in RAID. At least 1 drive is used for parity - one additional bit is added to the information cloned on it and in case a main disk stops working, this bit makes it easier to recalculate the bits of the files on the damaged hard disk so that the accurate information is restored on the new drive added to the RAID. Meanwhile, your websites will remain online since all the data will still load from at least one other hard drive. In the event that you add routine backups to your VPS package, a copy of the information will be stored on standard hard drives which also function in RAID as we want to make certain that any kind of website content you upload will be protected all the time. Working with multiple hard drives in RAID for all of the main and backup servers allows us to offer fast and reliable hosting service.
