RAID in Cloud Hosting
The SSD drives which our cutting-edge cloud hosting platform uses for storage function in RAID-Z. This type of RAID is created to work with the ZFS file system that runs on the platform and it takes advantage of the so-called parity disk - a specific drive where information stored on the other drives is copied with an extra bit added to it. If one of the disks stops working, your sites shall continue working from the other ones and after we replace the bad one, the data that will be cloned on it will be recovered from what is stored on the other drives together with the information from the parity disk. This is performed so as to be able to recalculate the bits of each file correctly and to confirm the integrity of the info cloned on the new drive. This is an additional level of security for the information you upload to your cloud hosting account together with the ZFS file system that compares a special digital fingerprint for each and every file on all the hard drives in real time.
RAID in Semi-dedicated Hosting
The RAID type which we employ for the cloud web hosting platform where your semi-dedicated hosting account will be created is called RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. Put simply, whenever any kind of data is copied on this specific drive, one more bit is added to it and in case a malfunctioning disk is changed, the info that will be duplicated 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 make sure that the info is intact. Throughout this process, your Internet sites will be working normally since RAID-Z makes it possible for an entire drive to fail without service interruptions and it simply works by using one of the remaining ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to warrant that no data shall get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS
The physical servers where we generate virtual private server work with quick SSD drives which will increase the speed of your websites noticeably. The hard drives work in RAID to make sure that you will not lose any data due to a power loss or a hardware failure. 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 information copied on it, which makes it much easier to recover the content without loss in case a main drive stops working. In case you use our backup service, your information will be stored on a separate 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 guarantee that we will have a backup of your content all of the time. With this particular setup your data will always be safe because it will be available on many drives.
