RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that enables a system to take advantage of a number of hard drives as one single logical unit. Put simply, all the drives are used as one and the information on all of them is identical. Such a configuration has 2 key advantages over using just a single drive to keep data - the first one is redundancy, so if one drive doesn't work, the information will be accessible from the others, and the second one is better performance since the input/output, or reading/writing operations will be spread among multiple drives. There're different RAID types depending on how many drives are used, whether reading and writing are both handled from all drives concurrently, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Determined by the particular setup, the error tolerance and the performance may vary.

RAID in Website Hosting

All content that you upload to your new website hosting account will be saved on fast SSD drives that work in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud web hosting platform and it adds another level of security for your content on top of the real-time checksum authentication which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on several disks and at least one is a parity disk - whenever information is written on it, an extra bit is added, so in case any drive stops functioning for some reason, the integrity of the data can be verified by recalculating its bits in accordance with what is kept on the production hard disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue operating efficiently until the problematic drive is replaced and the data is synchronized on it.

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 offer operate 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 copied on this type of a hard drive. If a disk fails and is replaced with another one, what info will be duplicated on the latter shall be a mix calculated between the data on the other hard disks and that on the parity one. This is done to guarantee that the information on the new drive will be correct. Throughout the procedure, the RAID will continue functioning normally and the problematic drive will not have an impact on the adequate operation of your Internet sites in any respect. Using SSDs in RAID-Z is a superb addition to the ZFS file system that runs on our revolutionary cloud platform in terms of preserving the integrity of your files since ZFS uses special digital identifiers identified as checksums to prevent silent data corruption.

RAID in VPS Web Hosting

All virtual private server accounts that our company provides 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 cloned on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the correct data is restored on the new drive added to the RAID. Meanwhile, your sites will stay online as all the data will still load from at least 1 more hard disk. If you add regular backups to your VPS package, a copy of the info will be saved on standard disk drives that also function in RAID as we would like to make sure that any website content you add will be protected all of the time. Employing multiple hard disks in RAID for all the main and backup servers allows us to offer fast and reliable hosting service.
