RAID in Shared Website Hosting
All of the content that you upload to your new shared website hosting account will be placed on quick SSD drives which function in RAID-Z. This configuration is built to use the ZFS file system which runs on our cloud Internet hosting platform and it adds another level of protection for your website content in addition to the real-time checksum authentication that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is saved on several disks and at least one of them is a parity disk - whenever information is recorded on it, an additional bit is added, so if any drive stops working for whatever reason, the integrity of the information 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 operation of our system won't be interrupted and it'll continue working flawlessly until the problematic drive is changed and the info is synced on it.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is kept on SSD drives which function in RAID-Z. One of the drives in such a setup is used for parity - whenever data is cloned 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 since the data will load from the other drives, and when a brand new drive is added, the info which will be duplicated on it will be a blend between the data on the parity disk and data stored on the other hard drives in the RAID. This is done so as to guarantee that the information which is being cloned is correct, so once the new drive is rebuilt, it could be included in the RAID as a production one. This is one more warranty for the integrity of your data because the ZFS file system which runs on our cloud web hosting platform compares a unique checksum of all the copies of the files on the different drives to avoid any chance of silent data corruption.
RAID in VPS Servers
In case you employ one of our VPS server solutions, any content you upload will be saved on SSD drives which work in RAID. At least 1 drive is employed for parity to ensure the integrity of the information. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk part of the RAID breaks down, your sites will continue working and when a new disk substitutes the defective one, the bits of the data that will be cloned on it are calculated using the healthy and the parity drives. By doing this, any possibility of corrupting data throughout the process is prevented. We also employ standard hard disks which operate in RAID for storing backups, so should you add this service to your VPS plan, your site content will be saved on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
