RAID, or Redundant Array of Independent Disks, is a technology of keeping data on multiple hard disk drives that operate together as one single logical unit. The drives can be physical or logical i.e. in the second case one drive is split into different ones through virtualization software. In any case, the very same information is kept on all drives and the basic benefit of employing this type of a setup is that if a drive fails, the data will remain available on the remaining ones. Employing a RAID also improves the overall performance because the input and output operations will be spread among a couple of drives. There are several types of RAID dependant upon how many hard disks are used, whether writing is performed on all drives in real time or just on one, and how the information is synchronized between the drives - whether it's written in blocks on one drive after another or it is mirrored from one on the others. All of these factors indicate that the fault tolerance and the performance between the various RAID types may vary.

RAID in Cloud Website Hosting

Our advanced cloud hosting platform where all cloud website hosting accounts are made employs fast SSD drives instead of the traditional HDDs, and they work in RAID-Z. With this configuration, multiple hard disk drives work together and at least a single one is a dedicated parity disk. Simply put, when data is written on the remaining drives, it is duplicated on the parity one adding an extra bit. This is carried out for redundancy as even in case a drive fails or falls out of the RAID for whatever reason, the information can be rebuilt and verified thanks to the parity disk and the data stored on the other ones, which means that not a thing will be lost and there won't be any service interruptions. This is an additional level of security for your info together with the revolutionary ZFS file system that uses checksums to make sure that all of the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The RAID type which we use for the cloud 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 employed as a parity drive. In simple terms, whenever any data is cloned on this specific disk drive, one more bit is added to it and if a problematic disk is replaced, the info which will be cloned on it is a combination of the data on the remaining drives in the RAID and that on the parity one. This is done to ensure that your info is intact. During this process, your Internet sites will be working normally since RAID-Z allows for an entire drive to fail without causing any service interruptions and it simply uses one of the other ones as the main production drive. Employing 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 need to worry about the integrity of your files.

RAID in VPS

All virtual private server accounts which we offer are created on physical servers that take advantage of SSD drives working in RAID. At least one drive is employed for parity - one additional bit is included in the data duplicated on it and if a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the failed disk drive so that the right information is recovered on the new drive included in the RAID. At the same time, your websites will stay online since all the info will still load from at least 1 more hard disk. If you add regular backups to your VPS plan, a copy of your data will be kept on standard hard disks that also function in RAID as we want to make certain that any sort of website content you add will be risk-free at all times. Employing multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
