RAID in Cloud Web Hosting
The disk drives which we employ for storage with our innovative cloud Internet hosting platform are not the classic HDDs, but high-speed solid-state drives (SSD). They work in RAID-Z - a special setup designed for the ZFS file system which we employ. All the content that you upload to your cloud web hosting account will be kept on multiple hard disks and at least one shall be used as a parity disk. This is a special drive where a further bit is included to any content copied on it. If a disk in the RAID fails, it'll be changed with no service disturbances and the data will be recovered on the new drive by recalculating its bits using the data on the parity disk plus that on the remaining disks. This is done to ensure the integrity of the info and together with the real-time checksum verification which the ZFS file system performs on all drives, you will never have to worry about the loss of any information no matter what.
RAID in Semi-dedicated Servers
The SSD drives which are used for holding any site 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 employed for parity i.e. the system will add an extra bit to any data cloned on this type of a disk drive. If a disk fails and is substituted with a new one, what info will be cloned on the latter will be a combination calculated between the data on the remaining drives and that on the parity one. This is done to ensure that the info on the new drive shall be correct. During the procedure, the RAID will continue operating adequately and the problematic drive won't have an effect on the adequate operation of your websites in any way. Using SSDs in RAID-Z is a great addition to the ZFS file system that runs on our state-of-the-art cloud platform with regards to preserving the integrity of your files as ZFS uses specific digital identifiers called checksums so as to prevent silent data corruption.
RAID in VPS Servers
All VPS server accounts that we provide are generated on physical servers that employ SSD drives working in RAID. At least 1 drive is used for parity - one extra bit is included in the information copied on it and in case a main disk stops working, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the accurate information is restored on the new drive added to the RAID. At the same time, your sites will still be online since all the information will still load from at least 1 more drive. If you add regular backups to your VPS package, a copy of your information will be saved on standard disk drives that also function in RAID because we want to make certain that any type of website content you upload will be risk-free at all times. Using multiple hard drives in RAID for all the main and backup servers permits us to offer fast and reliable hosting service.
