RAID, which stands short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology which makes it possible for a system to use several hard drives as a single logical unit. Simply put, all the drives are used as one and the info on all of them is the same. This kind of a configuration has two huge advantages over using just a single drive to store data - the first is redundancy, so if one drive fails, the information will be accessible through the others, and the second is improved performance because the input/output, or reading/writing operations will be spread among several drives. There are different RAID types in accordance with the number of drives are used, whether reading and writing are both handled from all of the drives simultaneously, if data is written in blocks on one drive after another or is mirrored between drives in the same time, etcetera. Determined by the exact setup, the fault tolerance and the performance may vary.

RAID in Cloud Hosting

The drives that we use for storage with our innovative cloud hosting platform are not the traditional HDDs, but fast NVMes. They operate in RAID-Z - a special setup intended for the ZFS file system which we work with. All of the content that you upload to your cloud hosting account will be kept on multiple drives and at least one of them will be used as a parity disk. This is a special drive where a further bit is included to any content copied on it. If a disk in the RAID fails, it'll be replaced without any service disruptions and the information will be rebuilt on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the other disks. This is done in order to guarantee the integrity of the data and along with the real-time checksum verification that the ZFS file system performs on all drives, you will never have to concern yourself with losing any data no matter what.

RAID in Semi-dedicated Hosting

If you host your sites in a semi-dedicated hosting account from our company, all of the content that you upload will be saved on NVMe drives which work in RAID-Z. With this form of RAID, at least 1 of the hard drives is used for parity - when data is synchronized between the hard drives, an extra bit is included in it on the parity one. The reasoning behind this is to guarantee the integrity of the data which is cloned to a brand new drive in the event that one of the hard drives in the RAID breaks down as the content being copied on the brand new disk is recalculated from the data on the standard drives and on the parity one. An additional advantage of RAID-Z is that even in the event that a drive fails, the system can switch to another one instantly without service disruptions of any sort. RAID-Z adds one more level of protection for the content which you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums so as to validate the integrity of each file.

RAID in VPS Web Hosting

All virtual private server accounts which we provide are generated on physical servers which take advantage of NVMe drives working in RAID. At least one drive is used for parity - one extra bit is added to the information duplicated on it and in case a main disk breaks down, this bit makes it simpler to recalculate the bits of the files on the damaged disk drive so that the right data is restored on the new drive added to the RAID. Meanwhile, your websites will remain online because all the data will still load from at least 1 more hard disk. If you add regular backups to your VPS plan, a copy of your data will be kept on standard hard drives which also operate in RAID since we want to make certain that any site content you upload will be protected at all times. Employing multiple hard disks in RAID for all of the main and backup servers allows us to offer fast and reliable web hosting service.
