Redundant Array of Independent Disks, or RAID, is a way of storing content on several hard drives simultaneously. A RAID might be software or hardware based on the HDDs that are used - physical or logical ones, still what is common between them is the fact that they all function as just a single unit where information is stored. The top advantage of employing a RAID is redundancy since the info on all of the drives shall be exactly the same all of the time, so even in the event that some drive fails for whatever reason, the info will still be present on the remaining drives. The overall performance will also improve as the reading and writing processes will be split between various drives, so a single one can't be overloaded. There are different types of RAIDs where the functionality and fault tolerance can vary according to the specific setup - whether your data is written on all drives real-time or it is written on a single drive and after that mirrored on another, the number of drives are used for the RAID, etcetera.

RAID in Cloud Website Hosting

All the content which you upload to your new cloud website hosting account will be held on quick NVMe drives that operate in RAID-Z. This configuration is built to use the ZFS file system which runs on our cloud web hosting platform and it adds an additional level of protection for your site content on top of the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is saved on a number of disks and at least one is a parity disk - whenever info is recorded on it, an additional bit is added, so if any drive fails for whatever reason, the stability of the data can be verified by recalculating its bits based on what is stored on the production disks and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it will continue operating efficiently until the malfunctioning drive is changed and the data is synchronized on it.

RAID in Semi-dedicated Servers

The data uploaded to any semi-dedicated server account is stored on NVMe drives that operate in RAID-Z. One of the drives in such a configuration is used for parity - any time data is cloned on it, an additional bit is added. If a disk turns out to be problematic, it will be removed from the RAID without disturbing the operation of the Internet sites as the data will load from the rest of the drives, and when a brand new drive is included, the info that will be duplicated on it will be a blend between the information on the parity disk and data kept on the other drives in the RAID. That is done so as to ensure that the data that is being cloned is correct, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is one more warranty for the integrity of your information since the ZFS file system which runs on our cloud hosting platform analyzes a unique checksum of all of the copies of your files on the various drives in order to avoid any probability of silent data corruption.

RAID in VPS Servers

All VPS server accounts which we provide are generated on physical servers which employ NVMe drives working in RAID. At least 1 drive is employed for parity - one extra bit is added to the data cloned on it and if a main disk fails, this bit makes it much simpler to recalculate the bits of the files on the failed hard disk so that the accurate info is recovered on the new drive added to the RAID. In the mean time, your websites will stay online since all the info will still load from at least 1 more hard drive. If you add regular backups to your VPS package, a copy of the info will be saved on standard hard drives which also work in RAID as we want to make certain that any kind of site content you add will be safe and sound all the time. Working with multiple drives in RAID for all the main and backup servers enables us to offer fast and reliable web hosting service.
