Redundant Array of Independent Disks, or RAID, is a method of keeping content on several hard disks simultaneously. A RAID might be software or hardware depending on the HDDs that are used - physical or logical ones, however what is common between them is the fact that they all operate as just one single unit where your information is kept. The top advantage of employing a RAID is redundancy since the information on all drives will be the same at all times, so even if a drive fails for whatever reason, the data will still be available on the remaining drives. The general performance is also better because the reading and writing processes will be split between multiple drives, so a single one can't be overloaded. There're different types of RAIDs where the functionality and fault tolerance may differ depending on the particular setup - whether information is written on all of the drives real-time or it's written on one drive and then mirrored on another, the number of drives are used for the RAID, and so on.

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 operate in RAID-Z - a special setup designed for the ZFS file system which we employ. All the content that you add to the cloud hosting account will be saved on multiple drives and at least one of them will be employed as a parity disk. This is a special drive where a further bit is added to any content copied on it. In the event that a disk in the RAID fails, it'll be replaced without any service disturbances and the information will be rebuilt on the new drive by recalculating its bits using the data on the parity disk along with that on the other disks. This is done so as to guarantee the integrity of the info and together with the real-time checksum authentication which the ZFS file system runs on all drives, you won't ever have to worry about the loss of any info no matter what.

RAID in Semi-dedicated Hosting

If you host your websites inside a semi-dedicated hosting account from our company, any content that you upload will be held 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 hard drives, an extra bit is included in it on the parity one. The reasoning behind this is to ensure the integrity of the data which is cloned to a new drive if one of the disks in the RAID breaks down since the site content being copied on the 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 if a hard drive stops functioning, the system could switch to another one quickly without service disturbances of any type. RAID-Z adds an extra level of safety for the content that you upload on our cloud Internet hosting platform in addition to the ZFS file system which uses unique checksums as a way to verify the integrity of every single file.

RAID in VPS Web Hosting

All virtual private server accounts that we offer are generated on physical servers which employ SSD drives working in RAID. At least 1 drive is employed for parity - one additional bit is included in the data cloned on it and in case a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the failed hard disk so that the right data is recovered on the new drive added to the RAID. At the same time, your Internet sites will stay online because all the info will still load from at least one other drive. In the event that you add routine backups to your VPS package, a copy of your information will be saved on standard hard drives which also work in RAID as we would like to make sure that any kind of website content you upload will be risk-free all of the time. Working with multiple hard drives in RAID for all the main and backup servers permits us to offer fast and reliable Internet hosting service.
