RAID in Website Hosting
All of the content which you upload to your new website hosting account will be saved on quick SSD drives which function in RAID-Z. This setup is built to employ the ZFS file system that runs on our cloud web hosting platform and it adds an additional level of security for your content on top of the real-time checksum verification which ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is stored on several disks and at least one is a parity disk - whenever information is recorded on it, an additional bit is added, so in case any drive stops functioning for some reason, the integrity of the data can be verified by recalculating its bits based on what is kept on the production hard disks and on the parity one. With RAID-Z, the functioning of our system won't be interrupted and it'll continue operating effectively until the malfunctioning drive is changed and the info is synced on it.
RAID in Semi-dedicated Hosting
The data uploaded to any semi-dedicated hosting account is saved on SSD drives which function in RAID-Z. One of the drives in such a configuration is used for parity - any time 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 interrupting the operation of the websites as the data will load from the rest of the drives, and when a new drive is included, the data that will be duplicated on it will be a blend between the data on the parity disk and data saved on the other drives in the RAID. This is done in order to guarantee that the info which is being copied is correct, so the moment the new drive is rebuilt, it could be integrated into the RAID as a production one. This is one more guarantee for the integrity of your data since the ZFS file system that runs on our cloud hosting platform compares a unique checksum of all copies of the files on the different drives so as to avoid any probability of silent data corruption.
RAID in VPS Web Hosting
If you use one of our virtual private server packages, any content that you upload will be stored on SSD drives that work in RAID. At least a single drive is employed for parity to ensure the integrity of your information. In simple terms, this is a special drive where information is copied with one bit added to it. In case a disk part of the RAID fails, your sites will continue working and when a new disk replaces the defective one, the bits of the info that will be duplicated on it are calculated using the healthy and the parity drives. This way, any potential for corrupting data during the process is averted. We also employ conventional hard disk drives that operate in RAID for storing backup copies, so should you include this service to your VPS plan, your website content will be saved on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive failures.
