RAID in Web Hosting
Any content that you upload to your new web hosting account will be held on fast SSD drives that operate in RAID-Z. This setup is built to employ the ZFS file system which runs on our cloud hosting platform and it adds one more level of security for your website content in addition to the real-time checksum validation that ZFS uses to ensure the integrity of the data. With RAID-Z, the information is saved on a couple of disks and at least one is a parity disk - whenever information is written on it, an additional bit is added, so if any drive stops working for some reason, the integrity of the data can be verified by recalculating its bits in accordance with what is stored on the production hard disks and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue functioning effectively until the malfunctioning drive is changed and the information is synced on it.
RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud web hosting platform where your semi-dedicated hosting account will be created is known as RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. Simply put, whenever any kind of data is copied on this specific drive, one more bit is added to it and if a malfunctioning disk is replaced, the info that will be duplicated on it is a combination of the data on the remaining drives in the RAID and that on the parity one. We do this to make sure that your data is intact. During this process, your websites will be functioning normally since RAID-Z makes it possible for a whole drive to fail without service interruptions and it simply uses one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to warrant that no data can get silently corrupted on our servers, you will not have to worry about the integrity of your files.
RAID in VPS Web Hosting
In case you employ one of our virtual private server packages, any content which you upload will be saved on SSD drives which function in RAID. At least one drive is used for parity to guarantee the integrity of the information. In simple terms, this is a special drive where data is copied with one bit added to it. If a disk from the RAID breaks down, your sites will continue working and when a new disk replaces the malfunctioning 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 probability of corrupting data throughout the process is prevented. We also employ ordinary hard disk drives that operate in RAID for storing backups, so if you include this service to your VPS plan, your site content will be stored on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
