RAID in Hosting
The disk drives that we employ for storage with our innovative cloud web hosting platform are not the traditional HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup developed for the ZFS file system which we use. All the content that you add to your hosting account will be kept on multiple disk drives and at least one shall be employed as a parity disk. This is a special drive where an extra bit is included to any content copied on it. In case a disk in the RAID stops working, it will be replaced with no service disturbances and the info will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk plus that on the other disks. This is done to guarantee the integrity of the data and together with the real-time checksum validation which the ZFS file system runs on all drives, you won't ever need to concern yourself with the loss of any info no matter what.
RAID in Semi-dedicated Hosting
The SSD drives which are used for saving any site content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a special setup where one or more hard drives are used for parity i.e. the system will include an additional bit to any data copied on such a drive. If a disk fails and is replaced with another one, what info will be duplicated on the latter shall be a mix calculated between the data on the remaining disks and that on the parity one. This is done to guarantee that the info on the new drive will be accurate. Throughout the procedure, the RAID will continue functioning adequately and the malfunctioning drive will not affect the adequate operation of your sites in any way. Working with SSDs in RAID-Z is an amazing addition to the ZFS file system which runs on our top-notch cloud platform with regard to preserving the integrity of your files as ZFS uses specific digital identifiers called checksums to prevent silent data corruption.
RAID in VPS
All virtual private server accounts that our company offers are made on physical servers that employ SSD drives operating in RAID. At least one drive is used for parity - one extra bit is added to the information 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 damaged hard disk so that the accurate data is restored on the new drive included in the RAID. At the same time, your websites will remain online because all the data will still load from at least one other disk drive. In the event that you add routine backups to your VPS plan, a copy of your info will be saved on standard hard disks that also operate in RAID because we would like to make sure that any type of website content you add will be protected all the time. Using multiple hard disks in RAID for all main and backup servers enables us to offer fast and reliable Internet hosting service.
