RAID in Website Hosting
The SSD drives that our cutting-edge cloud web hosting platform uses for storage work in RAID-Z. This sort of RAID is designed to work with the ZFS file system that runs on the platform and it takes advantage of the so-called parity disk - a specific drive where info located on the other drives is copied with an extra bit added to it. If one of the disks fails, your sites will continue working from the other ones and as soon as we replace the bad one, the info which will be cloned on it will be rebuilt from what is stored on the rest of the drives together with the data from the parity disk. This is performed so as to be able to recalculate the elements of every file correctly and to authenticate the integrity of the information cloned on the new drive. This is an additional level of security for the content which you upload to your website hosting account in addition to the ZFS file system that compares a unique digital fingerprint for each file on all the drives in real time.
RAID in Semi-dedicated Servers
The SSD drives that are used for storing any site content uploaded to the semi-dedicated server accounts which we provide work in RAID-Z. This is a special configuration where one or more hard drives are used for parity i.e. the system will add an extra bit to any data cloned on this kind of a disk drive. In case that a disk fails and is replaced with another one, what info will be duplicated on the latter shall be a combination calculated between the data on the other disks and that on the parity one. This is done to ensure that the data on the new drive shall be correct. During the procedure, the RAID will continue functioning normally and the problematic drive will not affect the normal operation of your sites at all. Using SSDs in RAID-Z is an outstanding addition to the ZFS file system that runs on our advanced cloud platform in terms of preserving the integrity of your files since ZFS uses unique digital identifiers known as checksums so as to avoid silent data corruption.
RAID in VPS Servers
All VPS server accounts which we provide are created on physical servers that employ SSD drives working in RAID. At least one drive is employed for parity - one extra bit is added to the information copied on it and if a main disk breaks down, this bit makes it easier to recalculate the bits of the files on the failed disk drive so that the correct info is recovered on the new drive included in the RAID. In the mean time, your Internet sites will remain online as all the info will still load from at least 1 more disk drive. If you add routine backups to your VPS package, a copy of the info will be kept on standard hard disks which also operate in RAID since we want to make sure that any type of website content you add will be safe and sound all of the time. Working with multiple drives in RAID for all main and backup servers permits us to offer fast and reliable web hosting service.
