Redundant Array of Independent Disks, or RAID, is a method of saving content on several hard disks simultaneously. A RAID might be software or hardware depending on the HDDs which are used - physical or logical ones, however what is common between them is the fact that they all operate as a single unit where your information is saved. The top advantage of employing a RAID is redundancy since the information on all drives is the same all of the time, so even in the event that a drive fails for whatever reason, the info will still be present on the remaining drives. The general performance is also better since the reading and writing processes could be split between multiple drives, so a single one can't be overloaded. There are different kinds of RAIDs where the capabilities and fault tolerance can vary based on the exact setup - whether data is written on all of the drives in real time or it's written on a single drive and then mirrored on another, the number of drives are used for the RAID, etc.

RAID in Shared Website Hosting

Any content which you upload to your new shared website hosting account will be saved on fast SSD drives that work in RAID-Z. This configuration is built to employ the ZFS file system that 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 verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a number of disks and at least 1 is a parity disk - whenever info is written on it, an additional bit is added, so if any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits in accordance with 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'll continue working effectively until the faulty drive is replaced and the info is synced on it.

RAID in Semi-dedicated Servers

In case you host your websites inside a semi-dedicated server account from our firm, all of the content that you upload will be saved on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the drives is used for parity - when data is synchronized between the drives, an extra bit is added to it on the parity one. The purpose behind this is to ensure the integrity of the information which is cloned to a new drive in the event that one of the drives in the RAID breaks down because the content being copied on the brand new disk is recalculated from the information on the standard disk drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a disk drive stops functioning, the system can switch to another one promptly without service disturbances of any sort. RAID-Z adds an additional level of protection for the content that you upload on our cloud web hosting platform in addition to the ZFS file system which uses unique checksums in order to verify the integrity of each and every file.

RAID in VPS Servers

All VPS server accounts which we provide are made on physical servers which take advantage of SSD drives working in RAID. At least one drive is used for parity - one extra bit is added to the data cloned on it and if a main disk breaks down, this bit makes it much simpler to recalculate the bits of the files on the damaged disk drive so that the right info is restored on the new drive added to the RAID. In the mean time, your websites will stay online as all the data will still load from at least one other drive. If you add regular backups to your VPS plan, a copy of your data will be saved on standard disk drives that also work in RAID since we want to make sure that any kind of website content you add will be protected all the time. Using multiple hard drives in RAID for all the main and backup servers permits us to offer fast and reliable web hosting service.
