RAID, or Redundant Array of Independent Disks, is a technology for keeping data on a number hard disks which operate together as one logical unit. The drives could be physical or logical i.e. in the latter case one single drive is split into independent ones using virtualization software. In any case, exactly the same information is stored on all drives and the key advantage of employing this kind of a setup is that in the event that a drive breaks down, the data will still be available on the other ones. Employing a RAID also boosts the performance because the input and output operations will be spread among a couple of drives. There are several kinds of RAID dependant upon how many hard disks are used, whether writing is carried out on all drives in real time or just on one, and how the info is synced between the drives - whether it's recorded in blocks on one drive after another or all of it is mirrored from one on the others. All these factors mean that the fault tolerance as well as the performance between the various RAID types could differ.

RAID in Cloud Hosting

Our state-of-the-art cloud Internet hosting platform where all cloud hosting accounts are made employs quick SSD drives as an alternative to the standard HDDs, and they function in RAID-Z. With this configuration, multiple hard disk drives work together and at least 1 is a dedicated parity disk. In simple terms, when data is written on the remaining drives, it's cloned on the parity one adding an extra bit. This is carried out 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 saved on the other ones, therefore not a thing will be lost and there will be no service disorders. This is another level of protection for your info together with the state-of-the-art ZFS file system that uses checksums to guarantee that all of the data on our servers is undamaged 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 named RAID-Z. What is different about it is that at least one of the disks is employed as a parity drive. In simple terms, whenever any data is copied on this specific drive, one more bit is included to it and if a faulty disk is replaced, the info that will be cloned on it is a combination of the data on the remaining drives in the RAID and that on the parity one. It's done this way to guarantee that your information is intact. Throughout this process, your websites will be working normally since RAID-Z enables a whole drive to fail without any service disturbances and it simply uses one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to ensure that no data will get silently corrupted on our servers, you will never need to worry about the integrity of your files.

RAID in VPS Web Hosting

All virtual private server accounts that we provide are generated on physical servers that take advantage of SSD drives working in RAID. At least one drive is intended for parity - one extra 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 damaged hard disk so that the correct info is restored on the new drive added to the RAID. Meanwhile, your Internet sites will still be online as all the information will still load from at least one other hard drive. If you add regular backups to your VPS plan, a copy of the data will be saved on standard disk drives that also function in RAID because we want to make sure that any type of website content you add will be safe and sound all of the time. Using multiple hard drives in RAID for all main and backup servers permits us to offer fast and reliable web hosting service.
