RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which permits a system to use many hard drives as one single logical unit. In other words, all the drives are used as one and the data on all of them is identical. This kind of a setup has 2 major advantages over using just a single drive to save data - the first one is redundancy, so in the event that one drive breaks down, the data will be accessible through the remaining ones, and the second one is improved performance because the input/output, or reading/writing operations will be distributed among multiple drives. There're different RAID types depending on what amount of drives are employed, whether reading and writing are both done from all drives simultaneously, whether data is written in blocks on one drive after another or is mirrored between drives in the same time, and many others. Determined by the exact setup, the fault tolerance and the performance vary.

RAID in Website Hosting

All the content that you upload to your new website hosting account will be held on quick NVMe drives that function in RAID-Z. This setup is built to work with the ZFS file system that runs on our cloud web hosting platform and it adds one more level of security for your site content in addition to the real-time checksum validation which ZFS uses to ensure the integrity of the data. With RAID-Z, the info is saved on several disks and at least one is a parity disk - whenever data is written on it, an additional bit is added, so if any drive fails for some reason, the integrity of the data can be verified by recalculating its bits based on what is kept on the production hard drives and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it will continue functioning smoothly until the malfunctioning drive is changed and the information is synced on it.

RAID in Semi-dedicated Hosting

The NVMe drives which are used for storing any site content uploaded to the semi-dedicated hosting accounts that we provide work in RAID-Z. This is a special setup where one or more hard drives are employed for parity i.e. the system will add an extra bit to any data duplicated on this type of a drive. In the event that a disk fails and is replaced with another one, what info will be duplicated on the latter will be a combination calculated between the data on the other drives and that on the parity one. This is done to guarantee that the data on the new drive will be accurate. Throughout the process, the RAID will continue working adequately and the malfunctioning drive will not impact the normal operation of your Internet sites in any respect. Working with NVMes in RAID-Z is a great addition to the ZFS file system that runs on our advanced cloud platform with regard to preserving the integrity of your files as ZFS uses special digital identifiers identified as checksums so as to avoid silent data corruption.

RAID in VPS Hosting

All virtual private server accounts which our company offers are generated on physical servers which employ NVMe drives functioning in RAID. At least 1 drive is used for parity - one extra bit is included in the data duplicated on it and in case a main disk fails, this bit makes it easier to recalculate the bits of the files on the damaged hard disk so that the right data is recovered on the new drive included in the RAID. At the same time, your websites will stay online because all the info will still load from at least one more drive. In the event that you add routine backups to your VPS plan, a copy of the data will be saved on standard hard disks which also function in RAID since we would like to make certain that any kind of website content you add will be safe and sound all the time. Working with multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
