RAID, or Redundant Array of Independent Disks, is a technology of saving data on a number hard disks which operate together as one single logical unit. The drives could be physical or logical i.e. in the second case one single drive is divided into different ones via virtualization software. Either way, identical information is saved on all drives and the main advantage of employing this kind of a setup is that in the event that a drive breaks down, the data will still be available on the other ones. Using a RAID also boosts the performance as the input and output operations will be spread among a few drives. There are several types of RAID dependant upon how many hard drives are used, whether writing is done on all drives in real time or just on a single one, and how the info is synchronized between the hard drives - whether it is written in blocks on one drive after another or it is mirrored from one on the others. These factors imply that the error tolerance and the performance between the various RAID types may differ.

RAID in Shared Website Hosting

Any content which you upload to your new shared website hosting account will be held on quick SSD drives which function in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud web hosting platform and it adds another level of security for your site content in addition to the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is stored on a couple of disks and at least one of them is a parity disk - whenever data is written on it, an extra bit is added, so if any drive fails for some reason, the stability of the information can be verified by recalculating its bits based on what is kept on the production hard disks and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it'll continue working efficiently until the faulty drive is changed and the info is synced on it.

RAID in Semi-dedicated Hosting

The SSD drives that are used for keeping any website content uploaded to the semi-dedicated hosting accounts which we provide function in RAID-Z. This is a specific setup where one or more disk drives are used for parity i.e. the system will include an extra bit to any data duplicated on this kind of a disk drive. If a disk fails and is replaced with a new one, what info will be cloned on the latter shall be a mix calculated between the data on the remaining hard disks and that on the parity one. This is done to ensure that the data on the new drive will be correct. Throughout the process, the RAID will continue operating adequately and the problematic drive won't affect the normal operation of your sites by any means. Working with SSDs in RAID-Z is a fantastic addition to the ZFS file system which runs on our top-notch cloud platform in terms of preserving the integrity of your files since ZFS uses specific digital identifiers called checksums in order to prevent silent data corruption.

RAID in VPS Hosting

All virtual private server accounts that our company offers are generated on physical servers which employ SSD drives operating in RAID. At least one drive is used for parity - one extra bit is included in the data cloned on it and in case a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the failed hard disk so that the correct data is recovered on the new drive included in the RAID. At the same time, your websites will stay online since all the info will still load from at least 1 other drive. In the event that you add regular backups to your VPS plan, a copy of your info will be stored on standard disk drives that also function in RAID because we would like to make certain that any type of website content you upload will be risk-free all the time. Working with multiple hard disks in RAID for all main and backup servers allows us to offer fast and reliable Internet hosting service.
