RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that permits a system to take advantage of several hard drives as a single logical unit. In other words, all the drives are used as one and the information on all of them is identical. This kind of a setup has 2 huge advantages over using a single drive to store data - the first one is redundancy, so in the event that one drive doesn't work, the information will be accessible from the remaining ones, and the second one is better performance because the input/output, or reading/writing operations will be distributed among multiple drives. There're different RAID types based on how many drives are used, if reading and writing are both handled from all of the drives concurrently, if data is written in blocks on one drive after another or is mirrored between drives in the same time, and so on. Determined by the exact setup, the error tolerance and the performance may vary.

RAID in Cloud Website Hosting

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

RAID in Semi-dedicated Hosting

The information uploaded to any semi-dedicated hosting account is saved on SSD drives that operate in RAID-Z. One of the drives in this kind of a setup is used for parity - each time data is cloned on it, an additional bit is added. In case a disk happens to be flawed, it will be removed from the RAID without disturbing the work of the Internet sites since the data will load from the remaining drives, and when a new drive is added, the data which will be cloned on it will be a blend between the data on the parity disk and data kept on the other hard drives in the RAID. That is done in order to guarantee that the data which is being duplicated is accurate, so once the new drive is rebuilt, it could be integrated into the RAID as a production one. This is an additional guarantee for the integrity of your information as the ZFS file system which runs on our cloud web hosting platform compares a unique checksum of all copies of your files on the various drives in order to avoid any probability of silent data corruption.

RAID in VPS Web Hosting

All virtual private server accounts that we offer are generated on physical servers which use SSD drives operating in RAID. At least 1 drive is intended for parity - one additional bit is added to the data cloned on it and if a main disk breaks down, this bit makes it much easier to recalculate the bits of the files on the damaged disk drive so that the correct data is restored on the new drive included in the RAID. Meanwhile, your websites will stay online as all the information will still load from at least one more hard disk. In the event that you add routine backups to your VPS package, a copy of the information will be stored on standard hard drives that also function in RAID since we would like to make sure that any kind of site content you add will be protected all of the time. Employing multiple hard disks in RAID for all main and backup servers allows us to offer fast and reliable Internet hosting service.
