RAID, or Redundant Array of Independent Disks, is a technology of storing data on multiple hard drives which function together as one logical unit. The drives could be physical or logical i.e. in the latter case one single drive is divided into separate ones using virtualization software. Either way, identical information is kept on all of the drives and the main benefit of using this kind of a setup is that in case a drive stops working, the data will remain available on the remaining ones. Using a RAID also improves the performance as the input and output operations will be spread among a few drives. There are several kinds of RAID dependant upon how many drives are used, whether writing is performed on all the drives in real time or just on a single one, and how the information is synchronized between the hard drives - whether it is written in blocks on one drive after another or all of it is mirrored from one on the others. All of these factors mean that the error tolerance as well as the performance between the various RAID types may vary.

RAID in Hosting

All the content that you upload to your new hosting account will be stored on fast SSD drives that operate in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds another level of protection for your content on top of the real-time checksum verification that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on several disks and at least one is a parity disk - whenever information is written on it, an extra bit is added, so in the event that any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits based on what is saved on the production hard drives and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue operating efficiently until the malfunctioning drive is replaced and the info is synced on it.

RAID in Semi-dedicated Hosting

If you host your Internet sites inside a semi-dedicated hosting account from our firm, all of the content that you upload will be stored on SSD drives which work in RAID-Z. With this kind of RAID, at least 1 of the drives is used for parity - when data is synchronized between the hard drives, an extra bit is added to it on the parity one. The idea behind this is to guarantee the integrity of the information that is cloned to a brand new drive if one of the drives in the RAID stops working since the website content being copied on the brand new disk is recalculated from the data on the standard hard drives and on the parity one. Another advantage of RAID-Z is that even in case a hard drive fails, the system can switch to a different one quickly without service disruptions of any kind. RAID-Z adds an additional level of security for the content that you upload on our cloud web hosting platform along with the ZFS file system that uses unique checksums to verify the integrity of each file.

RAID in VPS Web Hosting

In case you take advantage of one of our virtual private server solutions, any content which you upload will be stored on SSD drives that operate in RAID. At least a single drive is employed for parity to guarantee the integrity of your info. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk part of the RAID breaks down, your sites will continue working and when a new disk substitutes the faulty one, the bits of the data that will be duplicated on it are calculated by using the healthy and the parity drives. This way, any chance of corrupting data during the process is averted. We also use standard hard disks which work in RAID for storing backups, so in case you add this service to your VPS package, your site content will be stored on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
