RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to use multiple hard drives as one single logical unit. To put it differently, all of the drives are used as one and the info on all of them is identical. This type of a setup has 2 key advantages over using a single drive to keep data - the first is redundancy, so in the event that one drive stops working, the data will be accessible through the remaining ones, and the second is improved performance since the input/output, or reading/writing operations will be distributed among multiple drives. You can find different RAID types depending on how many drives are employed, if reading and writing are both executed from all of the drives simultaneously, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Depending on the exact setup, the fault tolerance and the performance may differ.

RAID in Cloud Hosting

All of the content which you upload to your new cloud hosting account will be stored on fast SSD drives that function in RAID-Z. This configuration is built to use the ZFS file system which runs on our cloud hosting platform and it adds an additional level of security for your website content in addition to the real-time checksum authentication that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is saved on a number of disks and at least one of them is a parity disk - whenever info is recorded on it, an extra bit is added, so in case any drive stops working for some reason, the stability of the information can be verified by recalculating its bits based on what is saved on the production hard disks and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue operating effectively until the faulty drive is replaced and the info is synced on it.

RAID in Semi-dedicated Servers

The SSD drives which are used for saving any website content uploaded to the semi-dedicated server accounts that we provide function 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 copied on this type of a disk drive. In the event that a disk fails and is replaced with a new one, what information will be duplicated on the latter will be a mix calculated between the data on the remaining hard disks and that on the parity one. This is done to make sure that the info on the new drive will be correct. During the procedure, the RAID will continue functioning adequately and the malfunctioning drive won't impact the normal operation of your Internet sites by any means. Working with SSDs in RAID-Z is a great addition to the ZFS file system which runs on our top-notch cloud platform with regards to preserving the integrity of your files because ZFS uses specific digital identifiers named checksums in order to avoid silent data corruption.

RAID in VPS Servers

All VPS server accounts which our company offers are made on physical servers that take advantage of SSD drives working in RAID. At least one drive is intended for parity - one extra bit is included in the information duplicated on it and if a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the damaged disk drive so that the accurate info is recovered on the new drive included in the RAID. At the same time, your websites will stay online because all the data will still load from at least 1 more disk drive. In case you add regular backups to your VPS plan, a copy of the information will be saved on standard disk drives that also operate in RAID as we would like to make sure that any type of site content you upload will be risk-free all of the time. Working with multiple hard drives in RAID for all main and backup servers allows us to offer fast and reliable Internet hosting service.
