RAID in Cloud Hosting
The hard disks which we employ for storage with our revolutionary cloud hosting platform are not the traditional HDDs, but high-speed solid-state drives (SSD). They work in RAID-Z - a special setup intended for the ZFS file system that we employ. Any content that you upload to your cloud hosting account will be saved on multiple disk drives and at least 1 will be employed as a parity disk. This is a specific drive where a further bit is included to any content copied on it. In case a disk in the RAID stops working, it will be replaced without any service interruptions and the data will be recovered on the new drive by recalculating its bits using the data on the parity disk plus that on the remaining disks. This is done so as to guarantee the integrity of the info and together with the real-time checksum authentication which the ZFS file system executes on all drives, you will never need to worry about the loss of any info no matter what.
RAID in Semi-dedicated Servers
The RAID type that we use for the cloud hosting platform where your semi-dedicated server account will be created is known 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 copied on this particular drive, one more bit is added to it and in the event that a malfunctioning disk is replaced, the information that will be copied on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. We do this to make sure that the data is intact. During this process, your websites will be functioning normally as RAID-Z makes it possible for a whole drive to fail without causing any service disruptions and it simply uses one of the remaining ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to warrant that no data will get silently corrupted on our servers, you will not need to worry about the integrity of your files.
RAID in VPS Servers
The physical servers where we create VPS server employ high-speed SSD drives which will boost the speed of your Internet sites noticeably. The disk drives work in RAID to guarantee that you will not lose any info as a result of a power loss or a hardware breakdown. The production servers employ many different drives where the info is kept and one disk is used for parity i.e. one bit is added to all information copied on it, that makes it much easier to restore the content without any loss in the event a main drive fails. In case you use our backup service, the information will be saved on a separate 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 make sure that we will have a backup of your site content all of the time. With this kind of setup your information will always be safe since it will be available on several drives.
