RAID in Shared Hosting
All the content that you upload to your new shared hosting account will be saved on fast SSD drives that function in RAID-Z. This setup is built to work with the ZFS file system which runs on our cloud web hosting platform and it adds one more level of security for your site content on top of the real-time checksum validation that ZFS uses to guarantee the integrity of the data. With RAID-Z, the data is saved on a couple of disks and at least one is a parity disk - whenever information is recorded on it, an extra bit is added, so in case any drive stops working for some reason, the integrity of the info can be verified by recalculating its bits in accordance with what is saved on the production hard disks and on the parity one. With RAID-Z, the operation of our system will never be interrupted and it will continue operating smoothly until the problematic drive is replaced and the data is synced on it.
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's different about it is that at least one of the disks is employed as a parity drive. Simply put, whenever any data is duplicated on this specific hard drive, one more bit is included to it and in case a problematic disk is changed, the info which 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. This is done to ensure that the info is intact. Throughout this process, your Internet sites will be up and running normally because RAID-Z allows for a whole drive to fail without any service interruptions and it simply uses one of the other ones as the main production drive. Using RAID-Z together with the ZFS file system that uses checksums to warrant that no data shall 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 create VPS server work with extremely fast SSD drives which will raise the speed of your websites substantially. The drives operate in RAID to guarantee that you won't lose any information because of a power loss or a hardware malfunction. The production servers use a variety of drives where the information is saved and one disk is used for parity i.e. one bit is added to all information copied on it, that makes it easier to restore the site content without loss in the event a main drive breaks down. If you use our backup service, the information will be stored on an independent machine that uses standard hard-disk drives and though there isn't a parity one in this case, they are also in a RAID to make sure that we will have a backup copy of your content at all times. With this particular configuration your data will always be safe since it will be available on several drives.
