RAID in Cloud Web Hosting
The drives that we employ for storage with our outstanding cloud hosting platform are not the traditional HDDs, but extremely fast solid-state drives (SSD). They function in RAID-Z - a special setup created for the ZFS file system which we work with. All of the content that you add to the cloud web hosting account will be stored on multiple drives and at least 1 will be employed as a parity disk. This is a specific drive where an additional bit is included to any content copied on it. In the event that a disk in the RAID stops working, it will be replaced with no service disturbances and the data 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 ensure the integrity of the information and together with the real-time checksum authentication that the ZFS file system performs on all drives, you won't ever have to worry about losing any data no matter what.
RAID in Semi-dedicated Servers
The RAID type that we employ for the cloud hosting platform where your semi-dedicated server account shall be created is referred to as RAID-Z. What is different about it is that at least 1 of the disks is used as a parity drive. Put simply, whenever any kind of data is duplicated on this special disk drive, one more bit is added to it and in case a defective disk is changed, the data that will be cloned on it is a combination of the data on the other hard disks in the RAID and that on the parity one. It's done this way to ensure that your data is intact. Throughout this process, your Internet sites will be functioning normally because RAID-Z allows for a whole drive to fail without causing any service interruptions and it simply works by using one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to ensure that no data will get silently corrupted on our servers, you will never need to worry about the integrity of your files.
RAID in VPS Servers
The physical servers where we make VPS server work with super fast SSD drives which will increase the speed of your Internet sites noticeably. The disk drives work in RAID to guarantee that you will not lose any data due to a power loss or a hardware breakdown. The production servers use many different drives where the information is kept and one disk is used for parity i.e. one bit is added to all of the data copied on it, that makes it easier to restore the site content without loss in case a main drive fails. If you take advantage of our backup service, your data will be stored on a separate machine which uses standard hard-disk drives and although there isn't a parity one in this case, they are also in a RAID to guarantee that we will have a backup copy of your website content all of the time. With this type of setup your data will always be safe because it will be available on many drives.
