Redundant Array of Independent Disks, or RAID, is a method of storing content on multiple hard disk drives simultaneously. A RAID could be software or hardware depending on the HDDs that are used - physical or logical ones, but what is common between them is that they all work as just one single unit where info is saved. The main advantage of using a RAID is redundancy because the information on all drives will be the same all the time, so even in case one of the drives fails for whatever reason, the data will still be present on the rest of the drives. The general performance is enhanced as well as the reading and writing processes can be split between various drives, so a single one will not be overloaded. There're different sorts of RAIDs where the functionality and fault tolerance can vary according to the exact setup - whether your data is written on all the drives real-time or it's written on a single drive and afterwards mirrored on another, what amount of drives are used for the RAID, etcetera.

RAID in Cloud Website Hosting

Any content that you upload to your new cloud website hosting account will be placed on fast SSD drives which operate in RAID-Z. This configuration is built to work with the ZFS file system which runs on our cloud Internet hosting platform and it adds an additional level of protection for your website content in addition to the real-time checksum authentication that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on several disks and at least 1 is a parity disk - whenever data is written on it, an extra bit is added, so in the event that any drive stops functioning for whatever reason, the integrity of the information can be verified by recalculating its bits based on what is saved on the production drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it'll continue operating effectively until the malfunctioning drive is replaced and the information is synchronized on it.

RAID in Semi-dedicated Hosting

The information uploaded to any semi-dedicated hosting account is kept on SSD drives that operate in RAID-Z. One of the drives in this kind of a setup is used for parity - every time data is copied on it, an extra bit is added. If a disk happens to be faulty, it will be taken out of the RAID without disturbing the functioning of the sites since the data will load from the remaining drives, and when a new drive is included, the information which will be cloned on it will be a mix between the information on the parity disk and data stored on the other hard drives in the RAID. This is done to guarantee that the info which is being cloned is accurate, so once the new drive is rebuilt, it could be integrated into the RAID as a production one. This is an additional warranty for the integrity of your info because the ZFS file system that runs on our cloud web hosting platform compares a unique checksum of all of the copies of your files on the various drives to avoid any chance of silent data corruption.

RAID in VPS

All virtual private server accounts that we offer are made on physical servers that take advantage of SSD drives functioning in RAID. At least 1 drive is used for parity - one extra bit is included in the info copied on it and in case a main disk stops working, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the accurate data is recovered on the new drive included in the RAID. Meanwhile, your Internet sites will stay online because all the info will still load from at least one other hard disk. In the event that you add routine backups to your VPS plan, a copy of the info will be saved on standard disk drives which also operate in RAID since we would like to make certain that any kind of website content you add will be safe and sound at all times. Using multiple hard drives in RAID for all of the main and backup servers enables us to offer fast and reliable Internet hosting service.
