RAID in Cloud Web Hosting
The revolutionary cloud Internet hosting platform where all cloud web hosting accounts are created uses super fast SSD drives as opposed to the standard HDDs, and they operate in RAID-Z. With this configuration, multiple hard disk drives function together and at least one of them is a dedicated parity disk. Basically, when data is written on the remaining drives, it is cloned on the parity one adding an extra bit. This is done for redundancy as even if a drive fails or falls out of the RAID for whatever reason, the information can be rebuilt and verified thanks to the parity disk and the data saved on the other ones, so not a thing will be lost and there won't be any service interruptions. This is one more level of security for your information along with the top-notch ZFS file system which uses checksums to make sure that all data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Hosting
The SSD drives that are used for saving any site content uploaded to the semi-dedicated hosting accounts that we offer operate in RAID-Z. This is a specific setup where one or more hard 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. If a disk fails and is substituted with another one, what information will be cloned on the latter will be a mix calculated between the data on the other disks and that on the parity one. This is done to make sure that the info on the new drive shall be correct. Throughout the procedure, the RAID will continue operating normally and the faulty drive won't impact the proper operation of your Internet sites in any way. Working with SSDs in RAID-Z is an outstanding addition to the ZFS file system which runs on our state-of-the-art cloud platform with regards to preserving the integrity of your files since ZFS uses specific digital identifiers referred to as checksums so as to prevent silent data corruption.
RAID in VPS Hosting
In case you use one of our virtual private server solutions, any content you upload will be stored on SSD drives which operate in RAID. At least a single drive is used for parity to guarantee the integrity of the info. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk from the RAID fails, your websites will continue working and when a new disk takes the place of the malfunctioning one, the bits of the information that will be copied on it are calculated by using the healthy and the parity drives. This way, any potential for corrupting data during the process is averted. We also use conventional hard disk drives that operate in RAID for storing backup copies, so should you add this service to your VPS package, your site content will be kept on multiple drives and you will never need to worry about its integrity even in the event of multiple drive breakdowns.
