Redundant Array of Independent Disks, or RAID, is a way of keeping content on a number of hard drives concurrently. A RAID can be software or hardware depending on the HDDs that are used - physical or logical ones, still what is common between them is the fact that they all perform as just one single unit where data is kept. The key advantage of using a RAID is redundancy as the data on all the drives is the same at all times, so even if a drive fails for whatever reason, the data will still be present on the remaining drives. The general performance is also enhanced since the reading and writing processes will be split between different drives, so a single one will not be overloaded. There're different sorts of RAIDs where the capabilities and fault tolerance may vary based on the particular setup - whether information is written on all drives in real time or it's written on one drive and then mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Cloud Web Hosting

The SSD drives that our cutting-edge cloud web hosting platform employs for storage work in RAID-Z. This sort of RAID is developed to work with the ZFS file system that runs on the platform and it takes advantage of the so-called parity disk - a specific drive where information located on the other drives is duplicated with an additional bit added to it. In case one of the disks fails, your websites will continue working from the other ones and as soon as we replace the faulty one, the data which will be cloned on it will be rebuilt from what is stored on the remaining drives along with the information from the parity disk. This is performed so as to be able to recalculate the bits of each file adequately and to validate the integrity of the info copied on the new drive. This is an additional level of security for the information which you upload to your cloud web hosting account along with the ZFS file system which analyzes a special digital fingerprint for each file on all of the drives in real time.

RAID in Semi-dedicated Hosting

If you host your websites inside a semi-dedicated hosting account from our firm, all of the content you upload will be held on SSD drives that work in RAID-Z. With this type of RAID, at least one of the drives is employed for parity - when data is synchronized between the drives, an additional bit is added to it on the parity one. The idea behind this is to ensure the integrity of the information which is cloned to a brand new drive if one of the drives in the RAID fails because the content being copied on the brand new disk is recalculated from the information on the standard hard drives and on the parity one. An additional advantage of RAID-Z is that even in case a disk drive stops functioning, the system could switch to another one quickly without service interruptions of any type. RAID-Z adds one more level of safety for the content which you upload on our cloud Internet hosting platform together with the ZFS file system which uses unique checksums in order to authenticate the integrity of each file.

RAID in VPS

All virtual private server accounts which we provide are made on physical servers that take advantage of SSD drives working in RAID. At least one drive is used for parity - one extra bit is included in the info cloned on it and in case a main disk stops working, this bit makes it easier to recalculate the bits of the files on the damaged hard disk so that the right data is restored on the new drive added to the RAID. At the same time, your Internet sites will still be online since all the data will still load from at least one other drive. If you add regular backups to your VPS plan, a copy of the data will be saved on standard hard drives that also function in RAID because we would like to make certain that any sort of website content you add will be safe and sound at all times. Using multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable hosting service.
