Redundant Array of Independent Disks, or RAID, is a way of storing content on multiple hard drives at the same time. A RAID might be software or hardware depending on the HDDs that are used - physical or logical ones, yet what’s common between them is the fact that they all operate as just a single unit where data is kept. The main advantage of using a RAID is redundancy because the information on all the drives will be exactly the same at all times, so even in the event that some drive fails for whatever reason, the data will still be available on the other drives. The overall performance is also better because the reading and writing processes can be split between various drives, so a single one will never be overloaded. There are different sorts of RAIDs where the capabilities and fault tolerance may vary based on the particular setup - whether info is written on all the drives real-time or it's written on a single drive and after that mirrored on another, what amount of drives are used for the RAID, etc.

RAID in Cloud Hosting

All the content that you upload to your new cloud hosting account will be held on quick SSD drives which operate in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud web hosting platform and it adds one more level of protection for your website content on top of the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the information is saved on several disks and at least one of them is a parity disk - whenever info is written on it, an extra bit is added, so in case any drive stops functioning for some reason, the stability of the information can be verified by recalculating its bits in accordance with what is kept on the production drives and on the parity one. With RAID-Z, the operation of our system will not be interrupted and it'll continue operating smoothly until the faulty drive is changed and the information is synchronized on it.

RAID in Semi-dedicated Hosting

The SSD drives which are used for keeping any content uploaded to the semi-dedicated hosting accounts that we offer operate in RAID-Z. This is a special setup where one or more disk drives are used for parity i.e. the system will add an extra bit to any data cloned on such a disk drive. If a disk fails and is replaced with a new one, what information will be cloned on the latter shall be a mix calculated between the data on the remaining drives and that on the parity one. This is done to ensure that the info on the new drive shall be accurate. During the procedure, the RAID will continue functioning adequately and the problematic drive will not impact the proper operation of your sites in any respect. Using SSDs in RAID-Z is an outstanding addition to the ZFS file system which runs on our state-of-the-art cloud platform in terms of preserving the integrity of your files as ZFS uses unique digital identifiers named checksums so as to prevent silent data corruption.

RAID in VPS Hosting

All virtual private server accounts that our company provides are generated on physical servers which use SSD drives functioning in RAID. At least 1 drive is used for parity - one additional bit is included in the information duplicated on it and in case a main disk fails, this bit makes it much simpler to recalculate the bits of the files on the damaged hard disk so that the accurate information is recovered on the new drive added to the RAID. At the same time, your websites will remain online since all the information will still load from at least 1 more disk drive. In the event that you add regular backups to your VPS package, a copy of your info will be kept on standard hard disks which also operate in RAID because we want to make certain that any site content you add will be safe and sound all the time. Working with multiple hard disks in RAID for all main and backup servers permits us to offer fast and reliable hosting service.
