RAID in Shared Web Hosting
Any content that you upload to your new shared web hosting account will be saved on quick SSD drives that work in RAID-Z. This configuration is built to employ the ZFS file system which runs on our cloud web hosting platform and it adds another level of protection for your website content in addition to the real-time checksum verification which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on a number of disks and at least one of them is a parity disk - whenever info is written on it, an extra bit is added, so in the event that any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits in accordance with what is saved on the production drives and on the parity one. With RAID-Z, the operation of our system won't be interrupted and it'll continue functioning effectively until the problematic drive is changed and the information is synced on it.
RAID in Semi-dedicated Servers
The info uploaded to any semi-dedicated server account is saved on SSD drives that work in RAID-Z. One of the drives in type of a configuration is used for parity - whenever data is copied on it, an additional bit is added. In case a disk turns out to be flawed, it will be removed from the RAID without interrupting the functioning of the websites as the data will load from the other drives, and when a brand new drive is added, the data that will be duplicated on it will be a mix between the information on the parity disk and data stored on the other drives in the RAID. This is done so as to guarantee that the info which is being copied is accurate, so the moment the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is one more warranty for the integrity of your info since the ZFS file system that runs on our cloud hosting platform compares a special checksum of all the copies of the files on the different drives to be able to avoid any probability of silent data corruption.
RAID in VPS Servers
All VPS server accounts that our company offers are made on physical servers that employ SSD drives working in RAID. At least one drive is intended for parity - one additional bit is included in the data duplicated on it and in case a main disk fails, this bit makes it much simpler to recalculate the bits of the files on the failed drive so that the accurate info is recovered on the new drive added to the RAID. Meanwhile, your websites will stay online since all the info will still load from at least one more disk drive. If you add routine backups to your VPS package, a copy of the data will be kept on standard hard drives that also operate in RAID because we would like to make certain that any type of site content you upload will be protected all of the time. Employing multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
