RAID, or Redundant Array of Independent Disks, is a technology for keeping data on multiple hard disk drives which operate together as a single logical unit. The drives can be physical or logical i.e. in the aforementioned case one single drive is divided into independent ones via virtualization software. Either way, identical information is stored on all drives and the key benefit of using this kind of a setup is that if a drive breaks down, the data will still be available on the other ones. Using a RAID also enhances the overall performance as the input and output operations will be spread among a couple of drives. There are several kinds of RAID based on how many hard drives are used, whether writing is done on all drives in real time or just on one, and how the information is synchronized between the hard drives - whether it's recorded in blocks on one drive after another or it is mirrored from one on the others. All these factors show that the fault tolerance as well as the performance between the various RAID types may differ.

RAID in Shared Website Hosting

Any content which you upload to your new shared website hosting account will be placed on fast SSD drives that work in RAID-Z. This setup is built to work with 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 ensure the integrity of the data. With RAID-Z, the data is saved on several disks and at least one is a parity disk - whenever information is recorded on it, an additional bit is added, so if any drive fails for whatever reason, the stability of the information can be verified by recalculating its bits in accordance with what is stored on the production disks and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue operating efficiently until the problematic drive is replaced and the info is synced on it.

RAID in Semi-dedicated Hosting

The SSD drives which are used for keeping any site content uploaded to the semi-dedicated hosting accounts that we offer function in RAID-Z. This is a special configuration where one or more drives are employed for parity i.e. the system will include an extra bit to any data duplicated on this type of a drive. In case that a disk fails and is replaced with another one, what info will be duplicated on the latter will be a combination calculated between the data on the other drives and that on the parity one. This is done to make sure that the information on the new drive shall be accurate. During the procedure, the RAID will continue operating normally and the malfunctioning drive will not affect the proper operation of your Internet sites by any means. Working with SSDs in RAID-Z is a great addition to the ZFS file system which runs on our revolutionary cloud platform with regards to preserving the integrity of your files since ZFS uses specific digital identifiers named checksums so as to avoid silent data corruption.

RAID in VPS Hosting

All virtual private server accounts that we provide are generated on physical servers that employ SSD drives working in RAID. At least one drive is employed for parity - one extra bit is included in the info copied on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged drive so that the accurate information is recovered on the new drive added to the RAID. At the same time, your websites will remain online because all the information will still load from at least 1 other hard drive. In the event that you add regular backups to your VPS plan, a copy of your info will be saved on standard hard disks which also function in RAID because we want to make certain that any site content you upload will be risk-free at all times. Employing multiple drives in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
