RAID in Cloud Hosting
Any content which you upload to your new cloud hosting account will be stored on quick SSD drives that work in RAID-Z. This setup is built to work with the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of security for your content in addition to the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on several disks and at least 1 is a parity disk - whenever information is recorded on it, an additional bit is added, so in case any drive stops functioning for whatever reason, the integrity of the data can be verified by recalculating its bits based on what is kept on the production drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue functioning smoothly until the malfunctioning drive is changed and the information is synchronized on it.
RAID in Semi-dedicated Hosting
The data uploaded to any semi-dedicated hosting account is saved on SSD drives that work in RAID-Z. One of the drives in type of a setup is used for parity - each time data is cloned on it, an additional bit is added. If a disk happens to be defective, it will be removed from the RAID without interrupting the operation of the Internet sites since the data will load from the rest of the drives, and when a brand new drive is added, the data which will be copied on it will be a blend between the info on the parity disk and data stored on the other hard drives in the RAID. That is done in order to ensure that the info which is being duplicated is correct, so once 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 data because the ZFS file system which runs on our cloud Internet hosting platform compares a special checksum of all copies of your files on the various drives to be able to avoid any chance of silent data corruption.
