Redundant Array of Independent Disks, or RAID, is a way of storing content on a number of hard disk drives at the same time. A RAID could be software or hardware depending on the hard drives which are used - physical or logical ones, but what’s common between them is the fact that they all perform as one single unit where information is saved. The top advantage of employing a RAID is redundancy because the information on all the drives shall be the same at all times, so even in the event that one of the drives fails for some reason, the information will still be available on the remaining drives. The general performance is also enhanced because the reading and writing processes will be split between different drives, so a single one won't be overloaded. There are different types of RAIDs where the capabilities and fault tolerance may differ according to the exact setup - whether info is written on all the drives real-time or it is written on one drive and then mirrored on another, what amount of drives are used for the RAID, etcetera.

RAID in Cloud Hosting

All content that you upload to your new cloud hosting account will be saved on quick SSD drives that function in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud hosting platform and it adds one more level of protection for your content on top of the real-time checksum verification that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on several disks and at least one is a parity disk - whenever data is recorded on it, an extra bit is added, so in case any drive stops working for whatever reason, the integrity of the info can be verified by recalculating its bits in accordance with what is kept on the production hard drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue operating flawlessly until the problematic drive is replaced and the info is synchronized on it.

RAID in Semi-dedicated Hosting

In case you host your sites in a semi-dedicated hosting account from our company, any content you upload will be kept on SSD drives which operate in RAID-Z. With this type of RAID, at least 1 of the disks is used for parity - when data is synced between the drives, an extra bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the data that is cloned to a new drive if one of the drives in the RAID breaks down because the website content being copied on the new disk is recalculated from the info on the standard drives and on the parity one. Another advantage of RAID-Z is that even if a disk drive fails, the system could switch to a different one quickly without service disturbances of any sort. RAID-Z adds an extra level of protection for the content which you upload on our cloud web hosting platform in addition to the ZFS file system that uses unique checksums so as to verify the integrity of each and every file.

RAID in VPS Hosting

The physical servers where we create virtual private server use super fast SSD drives which will raise the speed of your sites noticeably. The drives function in RAID to make sure that you will not lose any data because of a power loss or a hardware failure. The production servers take advantage of many different drives where the data is kept and one disk is used for parity i.e. one bit is added to all info copied on it, which makes it easier to restore the website content without loss if a main drive fails. In case you pick our backup service, the information will be saved on a separate machine which uses standard hard-disk drives and even though there isn't a parity one in this case, they are also in a RAID to guarantee that we will have a backup of your site content all the time. With this type of setup your information will always be safe because it will be available on multiple drives.
