RAID
Discover the advantages of having your websites and apps hosted on a RAID-enabled hosting server.
RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that allows a system to employ a number of hard drives as one single logical unit. Put simply, all of the drives are used as one and the info on all of them is identical. This type of a setup has two major advantages over using a single drive to store data - the first is redundancy, so in the event that one drive fails, the info will be accessible from the others, and the second is better performance as the input/output, or reading/writing operations will be spread among different drives. You can find different RAID types depending on what amount of drives are used, if reading and writing are both done from all the drives concurrently, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, and so on. Based on the particular setup, the error tolerance and the performance could differ.

RAID in Cloud Website Hosting
All the content which you upload to your new
cloud website hosting account will be saved on fast NVMe drives which operate in RAID-Z. This configuration is built to employ the ZFS file system that runs on our cloud Internet hosting platform and it adds an additional level of protection for your website content in addition to the real-time checksum verification that ZFS uses to guarantee the integrity of the data. With RAID-Z, the info is saved on a number of disks and at least one is a parity disk - whenever information is written on it, an extra bit is added, so in the event that any drive fails for whatever reason, the stability of the info can be verified by recalculating its bits based on what is stored on the production drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it'll continue functioning effectively until the problematic drive is replaced and the info is synced on it.

RAID in Semi-dedicated Hosting
The RAID type which we use for the cloud web hosting platform where your
semi-dedicated hosting account shall 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. In simple terms, whenever any data is duplicated on this special disk drive, one more bit is included to it and in case a defective disk is changed, the info that will be duplicated on it is a combination of the data on the remaining hard disks in the RAID and that on the parity one. It's done this way to guarantee that the data is intact. Throughout this process, your Internet sites will be working normally because RAID-Z makes it possible for a whole drive to fail without causing any service disruptions 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 guarantee that no data will get silently corrupted on our servers, you will not have to worry about the integrity of your files.
