Redundant Array of Independent Disks, or RAID, is a way of keeping content on multiple hard disks concurrently. A RAID can be software or hardware based on the HDDs which are used - physical or logical ones, but what’s common between them is that they all work as just a single unit where info is stored. The top advantage of employing a RAID is redundancy because the info on all drives shall be the same all of the time, so even if one of the drives fails for some reason, the information will still be present on the remaining drives. The general performance is also better since the reading and writing processes will be split between different drives, so a single one will not be overloaded. There're different types of RAIDs where the functionality and fault tolerance can vary according to the particular setup - whether your data is written on all drives in real time or it is written on one drive and then mirrored on another, the number of drives are used for the RAID, etc.

RAID in Cloud Hosting

Our revolutionary cloud Internet hosting platform where all cloud hosting accounts are made employs quick SSD drives instead of the classic HDDs, and they function in RAID-Z. With this setup, several hard disks operate together and at least one of them is a dedicated parity disk. Put simply, when data is written on the remaining drives, it is cloned on the parity one adding an extra bit. This is done for redundancy as even if a drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, which means that absolutely nothing will be lost and there will be no service disorders. This is an additional level of protection for your information along with the revolutionary ZFS file system which uses checksums to make sure that all data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Servers

The RAID type which we use for the cloud Internet hosting platform where your semi-dedicated server account shall be created is named RAID-Z. What's different about it is that at least 1 of the disks is used as a parity drive. Put simply, whenever any kind of data is copied on this particular disk drive, one more bit is included to it and in the event that a defective disk is replaced, the data that will be copied on it is a mix of the data on the remaining hard drives in the RAID and that on the parity one. It's done this way to guarantee that your data is intact. During this process, your websites will be functioning normally because RAID-Z enables an entire drive to fail without causing any service disruptions and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to guarantee that no data will get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.

RAID in VPS Servers

The physical servers where we create VPS server work with high-speed SSD drives which will boost the speed of your sites considerably. The disk drives work in RAID to ensure that you will not lose any data due to a power loss or a hardware failure. The production servers use multiple drives where the info is stored and one disk is used for parity i.e. one bit is added to all of the info copied on it, that makes it easier to recover the site content without loss in the event a main drive stops working. In case you choose our backup service, the info will be stored on an independent machine which uses standard hard-disk drives and although there isn't a parity one in this case, they are also in a RAID to ensure that we will have a backup copy of your website content all of the time. With this particular setup your info will always be safe as it will be available on a lot of drives.
