RAID in Shared Hosting
The disk drives that we employ for storage with our top-notch cloud hosting platform are not the traditional HDDs, but high-speed solid-state drives (SSD). They function in RAID-Z - a special setup created for the ZFS file system that we work with. All the content that you add to your shared hosting account will be held on multiple drives and at least one of them will be used as a parity disk. This is a specific drive where an extra bit is included to any content copied on it. If a disk in the RAID stops working, it will be changed without service disturbances and the data will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the remaining disks. This is done in order to guarantee the integrity of the info and together with the real-time checksum validation that the ZFS file system runs on all drives, you won't ever need to concern yourself with the loss of any information no matter what.
RAID in Semi-dedicated Servers
The info uploaded to any semi-dedicated server account is saved on SSD drives that function in RAID-Z. One of the drives in this kind of a configuration is used for parity - each time data is cloned on it, an extra bit is added. If a disk turns out to be flawed, it will be taken out of the RAID without interrupting the functioning of the Internet sites because the data will load from the rest of the drives, and when a brand new drive is added, the information 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. That is done so as to ensure that the data which is being copied is correct, so as soon as 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 info since the ZFS file system which runs on our cloud web hosting platform analyzes a unique checksum of all of the copies of your files on the separate drives in order to avoid any possibility of silent data corruption.
RAID in VPS Servers
The physical servers where we create VPS server employ super fast SSD drives which will boost the speed of your websites substantially. The hard drives function in RAID to guarantee that you won't lose any info because of a power loss or a hardware failure. The production servers take advantage of multiple drives where the info is kept and one disk is used for parity i.e. one bit is added to all of the info copied on it, which makes it much easier to recover the content without loss in the event a main drive stops working. In case you take advantage of our backup service, the data will be kept on an individual machine that uses standard hard-disk drives and though there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your content at all times. With this type of configuration your data will always be safe as it will be available on multiple disk drives.
