RAID in Shared Hosting
Any content which you upload to your new shared hosting account will be placed on quick SSD drives which operate in RAID-Z. This setup is built to employ the ZFS file system that runs on our cloud Internet hosting platform and it adds another level of protection for your content in addition to the real-time checksum authentication which ZFS uses to ensure the integrity of the data. With RAID-Z, the information is saved on a couple of disks and at least 1 is a parity disk - whenever data is written on it, an extra bit is added, so in case any drive stops working for whatever reason, the stability of the information 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 functioning of our system will never be interrupted and it'll continue functioning efficiently until the malfunctioning drive is replaced and the data is synced on it.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is stored on SSD drives which function in RAID-Z. One of the drives in such a setup is used for parity - each time data is copied on it, an extra bit is added. If a disk happens to be problematic, it will be taken out of the RAID without disturbing the operation of the Internet sites because the data will load from the other drives, and when a brand new drive is included, the info that will be duplicated on it will be a combination between the info on the parity disk and data stored on the other hard drives in the RAID. This is done so as to guarantee that the data which is being duplicated is accurate, so once the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is an additional warranty for the integrity of your information as the ZFS file system that runs on our cloud web hosting platform analyzes a unique checksum of all the copies of your files on the various drives to be able to avoid any possibility of silent data corruption.
