Redundant Array of Independent Disks, or RAID, is a way of saving content on a number of hard disks simultaneously. A RAID can be software or hardware depending on the hard drives that are used - physical or logical ones, still what’s common between them is that they all operate as just one single unit where your information is saved. The top advantage of using a RAID is redundancy as the information on all of the drives shall be the same all the time, so even in case a drive fails for whatever reason, the info will still be present on the remaining drives. The overall performance is also better since the reading and writing processes will be split between various drives, so a single one won't be overloaded. There're different types of RAIDs where the effectiveness and fault tolerance may differ based on the exact setup - whether information is written on all the drives real-time or it's written on one drive and afterwards mirrored on another, what amount of drives are used for the RAID, and so on.

RAID in Shared Website Hosting

The SSD drives that our cutting-edge cloud hosting platform uses for storage work in RAID-Z. This sort of RAID is developed to work with the ZFS file system which runs on the platform and it uses the so-called parity disk - a special drive where info saved on the other drives is copied with an additional bit added to it. In the event that one of the disks stops working, your websites shall continue working from the other ones and once we replace the bad one, the info which will be copied on it will be rebuilt from what is stored on the other drives as well as the data from the parity disk. This is done so as to be able to recalculate the elements of each file properly and to verify the integrity of the info copied on the new drive. This is one more level of security for the information that you upload to your shared website hosting account together with the ZFS file system that analyzes a unique digital fingerprint for every single file on all disk drives in real time.

RAID in Semi-dedicated Hosting

The SSD drives that are used for storing any website content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a special setup where one or more drives are employed for parity i.e. the system will include an extra bit to any data duplicated on this kind of a hard drive. If a disk fails and is replaced with a new one, what data will be cloned on the latter will be a combination calculated between the data on the remaining disks and that on the parity one. This is done to guarantee that the information on the new drive shall be correct. During the process, the RAID will continue operating adequately and the faulty drive will not impact the proper operation of your Internet sites in any respect. Using SSDs in RAID-Z is a fantastic addition to the ZFS file system which runs on our revolutionary cloud platform with regards to preserving the integrity of your files since ZFS uses unique digital identifiers identified as checksums so as to avoid silent data corruption.

RAID in VPS Hosting

The physical servers where we make virtual private server use fast SSD drives that will boost the speed of your sites substantially. The hard drives operate in RAID to make sure that you won't lose any data due to a power loss or a hardware failure. The production servers use a variety of drives where the information is saved and one disk is used for parity i.e. one bit is added to all the info copied on it, which makes it easier to recover the website content without loss in the event a main drive breaks down. In case you choose our backup service, the info will be stored on an independent 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 ensure that we will have a backup copy of your content all of the time. With this kind of setup your information will always be safe as it will be available on a lot of disk drives.
