RAID

Redundant Array of Independent Disks, or RAID, is a method of keeping content on a number of hard disk drives concurrently. A RAID might be software or hardware based on the drives that are used - physical or logical ones, but what is common between them is that they all perform as one single unit where your information is kept. The key advantage of employing a RAID is redundancy because the info on all of the drives is the same all of the time, so even if a drive fails for whatever reason, the data will still be available on the remaining drives. The overall performance is also enhanced since the reading and writing processes could be split between various drives, so a single one will not be overloaded. There're different types of RAIDs where the effectiveness and fault tolerance may differ based on the exact setup - whether your data is written on all of the drives real-time or it's written on one drive and afterwards mirrored on another, the number of drives are used for the RAID, and many others.

: RAID in Cloud Website Hosting

All of the content which you upload to your new cloud website hosting account will be held on quick NVMe drives that function in RAID-Z. This setup is built to use the ZFS file system that runs on our cloud Internet hosting platform and it adds one more level of security for your website content on top of the real-time checksum authentication which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on a couple of disks and at least one of them is a parity disk - whenever information is written on it, an additional bit is added, so in the event that any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits based on what is stored on the production disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue operating effectively until the problematic drive is replaced and the data is synchronized on it.; RAID in Semi-dedicated Servers

In case you host your sites within a semi-dedicated server account from our company, all the content that you upload will be saved on NVMe drives which work in RAID-Z. With this form of RAID, at least one of the disks is used for parity - when data is synchronized between the hard drives, an extra bit is included in it on the parity one. The idea behind this is to guarantee the integrity of the information which is cloned to a new drive in case one of the drives in the RAID fails as the website content being copied on the new disk is recalculated from the info on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even if a drive fails, the system can switch to another one promptly without service disruptions of any kind. RAID-Z adds an extra level of safety for the content you upload on our cloud hosting platform along with the ZFS file system which uses unique checksums in order to verify the integrity of each file.; RAID in VPS Servers

All VPS server accounts which our company provides are generated on physical servers which take advantage of NVMe drives functioning in RAID. At least one drive is employed for parity - one extra bit is added to the information cloned on it and in case a main disk fails, this bit makes it much easier to recalculate the bits of the files on the damaged hard disk so that the right info is restored on the new drive included in the RAID. Meanwhile, your Internet sites will remain online because all the information will still load from at least one other hard drive. In the event that you add routine backups to your VPS plan, a copy of the data will be saved on standard hard disks which also operate in RAID as we want to make sure that any type of content you add will be risk-free all the time. Using multiple hard drives in RAID for all the main and backup servers allows us to offer fast and reliable Internet hosting service.
