Redundant Array of Independent Disks, or RAID, is a way of saving content on a number of hard disks simultaneously. A RAID could be software or hardware based on the HDDs which are used - physical or logical ones, yet what’s common between them is that they all function as just a single unit where data is stored. The main advantage of using a RAID is redundancy since the info on all of the drives is the same at all times, so even in the event that one of the drives fails for whatever reason, the info will still be present on the remaining drives. The general performance is also better as the reading and writing processes will be split between various drives, so a single one will never be overloaded. There are different kinds of RAIDs where the effectiveness and fault tolerance could differ based on the specific setup - whether information is written on all the drives real-time or it's written on a single drive and then mirrored on another, what number of drives are used for the RAID, and many others.

RAID in Cloud Hosting

The disk drives which we employ for storage with our revolutionary cloud Internet hosting platform are not the traditional HDDs, but quick solid-state drives (SSD). They function in RAID-Z - a special setup intended for the ZFS file system that we employ. Any content that you add to the cloud hosting account will be stored on multiple drives and at least one of them will be employed as a parity disk. This is a special drive where an extra bit is added to any content copied on it. In the event that a disk in the RAID stops functioning, it will be changed with no service disruptions and the info will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the remaining disks. This is done so as to guarantee the integrity of the info and along with the real-time checksum authentication that the ZFS file system performs on all drives, you'll never need to concern yourself with the loss of any data no matter what.

RAID in Semi-dedicated Servers

The SSD drives which are used for saving any content uploaded to the semi-dedicated server accounts that we offer function in RAID-Z. This is a specific configuration where one or more drives are employed for parity i.e. the system will add an extra bit to any data cloned on this kind of a disk drive. In the event that a disk fails and is substituted with another one, what info will be duplicated on the latter shall be a combination calculated between the data on the remaining drives and that on the parity one. This is done to make sure that the info on the new drive will be correct. Throughout the procedure, the RAID will continue functioning adequately and the malfunctioning drive won't have an impact on the adequate operation of your Internet sites in any respect. Working with SSDs in RAID-Z is a fantastic addition to the ZFS file system that runs on our revolutionary cloud platform in terms of preserving the integrity of your files because ZFS uses specific digital identifiers called checksums to avoid silent data corruption.

RAID in VPS Servers

All VPS server accounts that our company offers are created on physical servers that employ SSD drives working in RAID. At least one drive is intended for parity - one extra bit is added to the information duplicated on it and in case a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the correct data is restored on the new drive added to the RAID. In the mean time, your sites will still be online as all the information will still load from at least 1 other disk drive. In the event that you add routine backups to your VPS package, a copy of your info will be saved on standard disk drives that also operate in RAID since we want to make certain that any type of content you upload will be risk-free all of the time. Using multiple hard drives in RAID for all of the main and backup servers allows us to offer fast and reliable hosting service.
