Redundant Array of Independent Disks, or RAID, is a way of saving content on several hard drives at the same time. A RAID might be software or hardware depending on the HDDs which are used - physical or logical ones, however what is common between them is that they all perform as just a single unit where data is kept. The key advantage of using a RAID is redundancy because the info on all drives shall be exactly the same all of the time, so even in case one of the drives fails for some reason, the data will still be present on the other drives. The general performance will also improve since the reading and writing processes will be split between a number of drives, so a single one can't be overloaded. There are different kinds of RAIDs where the functionality and fault tolerance may differ depending on the particular setup - whether info is written on all of the drives in real time or it's written on a single drive and after that mirrored on another, what number of drives are used for the RAID, and so on.

RAID in Cloud Hosting

The disk drives which we employ for storage with our innovative cloud hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup intended for the ZFS file system which we work with. All of the content that you upload to your cloud hosting account will be held on multiple hard drives and at least one will be used as a parity disk. This is a special drive where an extra bit is added to any content copied on it. In case a disk in the RAID stops working, it will be replaced with no service disturbances and the information will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the remaining disks. This is done in order to ensure the integrity of the data and along with the real-time checksum authentication which the ZFS file system executes on all drives, you will never need to worry about losing any info no matter what.

RAID in Semi-dedicated Hosting

The RAID type which we use for the cloud Internet hosting platform where your semi-dedicated hosting account will be created is named RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. In simple terms, whenever any kind of data is cloned on this special disk drive, one more bit is included to it and if a malfunctioning disk is replaced, the info which will be copied on it is a mix of the data on the other hard drives in the RAID and that on the parity one. It's done this way to ensure that your info is intact. Throughout this process, your Internet sites will be functioning normally because RAID-Z allows for a whole drive to fail without causing any service interruptions and it simply works by using one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to ensure that no data can get silently corrupted on our servers, you will never have to worry about the integrity of your files.

RAID in VPS Web Hosting

The physical servers where we create virtual private server use high-speed SSD drives that will boost the speed of your sites significantly. The disk drives function in RAID to make sure that you won't lose any data as a result of a power loss or a hardware malfunction. The production servers use a variety of drives where the data is stored and one disk is used for parity i.e. one bit is added to all info copied on it, which makes it much easier to restore the website content without any loss in case a main drive breaks down. If you take advantage of our backup service, the info will be saved on an independent machine that uses standard hard-disk drives and even though there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your content all the time. With this kind of configuration your information will always be safe because it will be available on many drives.
