RAID, which is an acronym of Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which enables a system to employ many hard drives as a single logical unit. Simply put, all drives are used as one and the data on all of them is the same. This kind of a setup has two huge advantages over using just a single drive to store data - the first is redundancy, so in the event that one drive doesn't work, the data will be accessed through the others, and the second one is better performance because the input/output, or reading/writing operations will be distributed among different drives. There are different RAID types based on what number of drives are employed, if reading and writing are both handled from all drives at the same time, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Determined by the exact setup, the error tolerance and the performance could differ.

RAID in Cloud Website Hosting

Our advanced cloud Internet hosting platform where all cloud website hosting accounts are generated uses quick SSD drives instead of the standard HDDs, and they operate in RAID-Z. With this setup, numerous hard drives operate together and at least one of them is a dedicated parity disk. In simple terms, when data is written on the remaining drives, it is copied on the parity one adding an extra bit. This is done for redundancy as even if some drive fails or falls out of the RAID for whatever reason, the info can be rebuilt and verified using the parity disk and the data recorded on the other ones, therefore practically nothing will be lost and there will be no service disorders. This is another level of protection for your info along with the advanced ZFS file system that uses checksums to guarantee that all of the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The RAID type that we employ for the cloud Internet hosting platform where your semi-dedicated hosting account shall be created is known as RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. Put simply, whenever any data is cloned on this specific disk drive, one more bit is included to it and in case a defective disk is replaced, the information which 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. This is done to ensure that your information is intact. During this process, your websites will be functioning normally as RAID-Z allows for a whole drive to fail without service disruptions and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system which uses checksums to ensure that no data shall get silently corrupted on our servers, you'll never need to worry about the integrity of your files.

RAID in VPS Web Hosting

All virtual private server accounts that our company offers are created on physical servers which take advantage of SSD drives working in RAID. At least 1 drive is intended for parity - one additional bit is added to the information duplicated on it and in case a main disk fails, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the correct info is recovered on the new drive added to the RAID. At the same time, your websites will still be online as all the information will still load from at least one other disk drive. In the event that you add regular backups to your VPS package, a copy of your information will be kept on standard hard disks that also function in RAID because we want to make sure that any website content you add will be safe and sound all the time. Employing multiple drives in RAID for all of the main and backup servers permits us to offer fast and reliable hosting service.
