RAID in Shared Web Hosting
The drives that we use for storage with our revolutionary cloud web hosting platform are not the classic HDDs, but fast solid-state drives (SSD). They work in RAID-Z - a special setup created for the ZFS file system which we use. All of the content that you upload to your shared web hosting account will be kept on multiple drives and at least one will be used as a parity disk. This is a special drive where an additional bit is added to any content copied on it. If a disk in the RAID stops working, it'll be replaced with no service interruptions and the information will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk plus that on the remaining disks. This is done to guarantee the integrity of the info and along with the real-time checksum authentication that the ZFS file system runs on all drives, you'll never need to concern yourself with losing any info no matter what.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is kept on SSD drives that function in RAID-Z. One of the drives in type of a setup is used for parity - any time data is cloned on it, an extra bit is added. In case a disk turns out to be problematic, it will be removed from the RAID without disturbing the operation of the sites since the data will load from the remaining drives, and when a new drive is added, the data that will be duplicated on it will be a blend between the data on the parity disk and data stored on the other hard disks in the RAID. That is done in order to guarantee that the data that is being cloned is correct, so the moment the new drive is rebuilt, it could be included in the RAID as a production one. This is one more guarantee for the integrity of your information as the ZFS file system which runs on our cloud Internet hosting platform analyzes a special checksum of all the copies of your files on the different drives so as to avoid any probability of silent data corruption.
RAID in VPS Servers
If you take advantage of one of our VPS server solutions, any content you upload will be saved on SSD drives that operate in RAID. At least one drive is employed for parity so as to guarantee the integrity of your data. In simple terms, this is a special drive where data is copied with one bit added to it. If a disk part of the RAID stops functioning, your websites will continue working and when a new disk substitutes the malfunctioning one, the bits of the information that will be duplicated on it are calculated using the healthy and the parity drives. That way, any possibility of corrupting data during the process is prevented. We also use standard hard disks which operate in RAID for storing backup copies, so if you add this service to your VPS plan, your website content will be kept on multiple drives and you'll never need to worry about its integrity even in the event of multiple drive breakdowns.
