RAID, or Redundant Array of Independent Disks, is a technology of keeping data on a number hard disks which work together as one logical unit. The drives could be physical or logical i.e. in the aforementioned case one drive is divided into different ones through virtualization software. Either way, the very same data is kept on all the drives and the basic advantage of using such a setup is that if a drive fails, the data will remain available on the other ones. Employing a RAID also boosts the overall performance since the input and output operations will be spread among several drives. There are several kinds of RAID depending on how many hard disks are used, whether writing is done on all the drives in real time or just on one, and how the information is synced between the drives - whether it is recorded in blocks on one drive after another or it is mirrored from one on the others. These factors show that the error tolerance as well as the performance between the various RAID types could differ.

RAID in Cloud Hosting

All the content which you upload to your new cloud hosting account will be stored on quick SSD drives which operate in RAID-Z. This configuration is built to use the ZFS file system which runs on our cloud hosting platform and it adds one more level of security for your content in addition to the real-time checksum verification which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on a number of disks and at least one is a parity disk - whenever information is recorded on it, an additional bit is added, so in case any drive fails for some reason, the integrity of the info can be verified by recalculating its bits based on what is saved on the production disks and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it'll continue working efficiently until the problematic drive is replaced and the data is synchronized on it.

RAID in Semi-dedicated Hosting

In case you host your websites in a semi-dedicated hosting account from our firm, all the content you upload will be stored on SSD drives which work in RAID-Z. With this type of RAID, at least one of the disks is employed for parity - when data is synchronized between the hard drives, an additional bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the info that is cloned to a brand new drive in the event that one of the hard drives in the RAID breaks down because the website content being copied on the brand new disk is recalculated from the info on the standard drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a disk drive stops working, the system can switch to a different one quickly without service disruptions of any kind. RAID-Z adds an extra level of safety for the content which you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums in order to validate the integrity of each and every file.

RAID in VPS Web Hosting

All virtual private server accounts that we provide are generated on physical servers that take advantage of SSD drives operating in RAID. At least one drive is used for parity - one extra bit is added to the info cloned on it and in case a main disk fails, this bit makes it much easier to recalculate the bits of the files on the damaged hard disk so that the correct data is restored on the new drive added to the RAID. At the same time, your websites will still be online since all the info will still load from at least 1 more hard drive. In the event that you add regular backups to your VPS plan, a copy of your info will be saved on standard hard drives which also function in RAID since we want to make sure that any site content you add will be protected all of the time. Using multiple hard drives in RAID for all the main and backup servers enables us to offer fast and reliable Internet hosting service.
