RAID in Cloud Hosting
All the content that you upload to your new cloud hosting account will be saved on quick SSD drives which work in RAID-Z. This configuration is built to use the ZFS file system which runs on our cloud Internet hosting platform and it adds one more level of protection for your content in addition to the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is stored on a couple of disks and at least one is a parity disk - whenever information is recorded on it, an additional bit is added, so in the event that any drive fails for some reason, the integrity of the info can be verified by recalculating its bits based on what is saved on the production disks and on the parity one. With RAID-Z, the operation of our system will never be interrupted and it'll continue functioning flawlessly until the malfunctioning drive is replaced and the info is synced on it.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is saved on SSD drives that function in RAID-Z. One of the drives in type of a setup is used for parity - whenever data is copied on it, an extra bit is added. In case a disk happens to be problematic, it will be removed from the RAID without disturbing the functioning of the sites because the data will load from the rest of the drives, and when a brand new drive is added, the info which will be copied on it will be a blend between the information on the parity disk and data kept on the other drives in the RAID. That is done to guarantee that the info which is being duplicated is accurate, so as soon as the new drive is rebuilt, it can be incorporated into the RAID as a production one. This is an additional warranty for the integrity of your info as the ZFS file system that runs on our cloud hosting platform analyzes a special checksum of all copies of your files on the various drives in order to avoid any possibility of silent data corruption.
RAID in VPS Servers
In case you use one of our VPS server plans, any content that you upload will be kept on SSD drives which operate in RAID. At least one drive is intended for parity so as to guarantee the integrity of the data. In simple terms, this is a special drive where info is copied with one bit added to it. If a disk part of the RAID stops functioning, your websites will continue working and when a new disk takes the place of the faulty one, the bits of the info that will be cloned on it are calculated using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is avoided. We also use regular hard disks which operate in RAID for storing backups, so should you include this service to your VPS package, your website content will be kept on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
