RAID in Cloud Website Hosting
The hard disks which we use for storage with our revolutionary cloud Internet hosting platform are not the classic HDDs, but high-speed solid-state drives (SSD). They function in RAID-Z - a special setup developed for the ZFS file system which we use. All of the content that you upload to your cloud website hosting account will be held on multiple hard drives and at least one of them shall be employed as a parity disk. This is a special drive where an extra bit is added to any content copied on it. In the event that a disk in the RAID stops working, it will be changed with no service disturbances and the info will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the remaining disks. This is done to guarantee the integrity of the information and together with the real-time checksum authentication that the ZFS file system runs on all drives, you will never have to be concerned about the loss of any data no matter what.
RAID in Semi-dedicated Servers
The information uploaded to any semi-dedicated server account is saved on SSD drives which operate in RAID-Z. One of the drives in such a setup is used for parity - each time data is cloned 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 brand new drive is included, the data that will be duplicated on it will be a blend between the info on the parity disk and data kept on the other hard disks in the RAID. That is done in order to ensure that the information that is being copied is correct, so as soon as the new drive is rebuilt, it could be incorporated into the RAID as a production one. This is an extra guarantee for the integrity of your data as the ZFS file system that runs on our cloud Internet hosting platform compares a unique checksum of all of the copies of the files on the various drives in order to avoid any chance of silent data corruption.
RAID in VPS Servers
The physical servers where we make VPS server use extremely fast SSD drives that will increase the speed of your sites substantially. The disk drives work in RAID to make sure that you will not lose any information as a result of a power loss or a hardware breakdown. The production servers use multiple drives where the data is stored and one disk is used for parity i.e. one bit is added to all information copied on it, which makes it easier to recover the site content without any loss in case a main drive breaks down. In case you choose our backup service, the info will be stored on an individual machine that uses standard hard-disk drives and although there isn't a parity one in this case, they are also in a RAID to ensure that we will have a backup copy of your website content all of the time. With this particular setup your information will always be safe as it will be available on multiple drives.
