Redundant Array of Independent Disks, or RAID, is a way of keeping content on several hard drives simultaneously. A RAID can be software or hardware based on the HDDs that are used - physical or logical ones, still what is common between them is that they all function as one single unit where info is kept. The key advantage of employing a RAID is redundancy as the info on all of the drives is exactly the same at all times, so even if one of the drives fails for whatever reason, the data will still be present on the other drives. The overall performance is also better because the reading and writing processes will be split between different drives, so a single one won't be overloaded. There are different types of RAIDs where the performance and fault tolerance can vary based on the specific setup - whether data is written on all of the drives in real time or it is written on a single drive and then mirrored on another, what number of drives are used for the RAID, and many others.

RAID in Website Hosting

All content that you upload to your new website hosting account will be saved on quick SSD drives which operate in RAID-Z. This configuration is built to use the ZFS file system that runs on our cloud hosting platform and it adds another level of security for your website content on top of the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is saved on several disks and at least one of them is a parity disk - whenever data is recorded on it, an additional bit is added, so if any drive stops working for some reason, the integrity of the information can be verified by recalculating its bits in accordance with what is stored on the production hard drives and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it will continue functioning flawlessly until the malfunctioning drive is changed and the information is synced on it.

RAID in Semi-dedicated Hosting

The information uploaded to any semi-dedicated hosting account is saved on SSD drives that work in RAID-Z. One of the drives in type of a configuration is used for parity - any time data is cloned on it, an extra bit is added. If a disk happens to be flawed, it will be removed from the RAID without disturbing the functioning of the sites because the data will load from the remaining drives, and when a new drive is added, the information that will be copied on it will be a combination between the data on the parity disk and data saved on the other hard drives in the RAID. That is done to ensure that the information which is being cloned is accurate, so as soon as the new drive is rebuilt, it can be integrated into the RAID as a production one. This is an extra warranty for the integrity of your data as the ZFS file system that runs on our cloud hosting platform analyzes a special checksum of all of the copies of the files on the separate drives in order to avoid any probability of silent data corruption.

RAID in VPS Hosting

All virtual private server accounts which we provide are made on physical servers that take advantage of SSD drives working in RAID. At least 1 drive is employed for parity - one additional bit is added to the information copied on it and if a main disk fails, this bit makes it easier to recalculate the bits of the files on the damaged drive so that the correct info is restored 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 disk. If you add regular backups to your VPS package, a copy of your info will be kept on standard hard drives which also operate in RAID since we want to make sure that any type of website content you upload will be protected at all times. Employing multiple hard drives in RAID for all the main and backup servers enables us to offer fast and reliable hosting service.
