RAID in Cloud Hosting
The NVMe drives that our cutting-edge cloud web hosting platform employs for storage operate in RAID-Z. This kind of RAID is developed to work with the ZFS file system that runs on the platform and it employs the so-called parity disk - a special drive where information kept on the other drives is copied with an extra bit added to it. In case one of the disks fails, your websites shall continue working from the other ones and after we replace the faulty one, the info that will be cloned on it will be rebuilt from what is stored on the remaining drives as well as the info from the parity disk. This is performed in order to be able to recalculate the elements of every single file adequately and to confirm the integrity of the data duplicated on the new drive. This is one more level of security for the information that you upload to your cloud hosting account in addition to the ZFS file system that analyzes a unique 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 use for the cloud web hosting platform where your semi-dedicated hosting account will be created is referred to as RAID-Z. What is different about it is that at least one of the disks is employed as a parity drive. Put simply, whenever any kind of data is cloned on this specific disk drive, one more bit is added to it and in case a problematic disk is changed, the data that will be cloned on it is a mix of the data on the other hard drives in the RAID and that on the parity one. It's done this way to make sure that your data is intact. During this process, your sites will be functioning normally since RAID-Z enables a whole drive to fail without causing any service interruptions 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 ensure that no data will get silently corrupted on our servers, you won't ever need to worry about the integrity of your files.
RAID in VPS Web Hosting
The NVMe drives which we use on the machines where we generate virtual private servers operate in RAID to ensure that any content that you upload will be available and intact all the time. At least a single drive is employed for parity - one bit of info is added to any data cloned on it. In case a main drive fails, it is changed and the data that will be copied on it is calculated between the remaining drives and the parity one. It's done this way to make sure that the correct data is copied and that not a single file is corrupted as the new drive will be a part of the RAID afterwards. We also use hard disk drives functioning in RAID on the backup servers, so if you add this upgrade to your VPS package, you shall use an even more reliable hosting service as your content will be available on multiple drives regardless of any kind of sudden hardware failure.
