RAID, which is short for Redundant Array of Independent Disks, is a software or hardware storage virtualization technology that enables a system to employ a number of hard drives as one single logical unit. In other words, all drives are used as one and the info on all of them is the same. This type of a configuration has two major advantages over using just a single drive to keep data - the first is redundancy, so in case one drive fails, the info will be accessed through the others, and the second is better performance because the input/output, or reading/writing operations will be spread among different drives. You can find different RAID types based on what amount of drives are employed, whether reading and writing are both done 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, and so on. Based on the particular setup, the error tolerance and the performance could differ.

RAID in Cloud Hosting

The cutting-edge cloud Internet hosting platform where all cloud hosting accounts are created uses fast SSD drives instead of the standard HDDs, and they function in RAID-Z. With this configuration, a number of hard disk drives work together and at least one of them is a dedicated parity disk. Simply put, when data is written on the remaining drives, it's copied on the parity one adding an extra bit. This is done for redundancy as even in case a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified using the parity disk and the data stored on the other ones, so not a thing will be lost and there won't be any service disorders. This is an additional level of security for your info in addition to the cutting-edge ZFS file system which uses checksums to make sure that all data on our servers is intact and is not silently corrupted.

RAID in VPS Web Hosting

All virtual private server accounts which we offer are made on physical servers which employ SSD drives operating in RAID. At least one drive is employed for parity - one extra bit is included in the data copied on it and if a main disk fails, this bit makes it simpler to recalculate the bits of the files on the damaged hard disk so that the accurate information is restored on the new drive included in the RAID. Meanwhile, your websites will stay online as all the data will still load from at least one other hard drive. In the event that you add routine backups to your VPS package, a copy of the information will be saved on standard disk drives that also operate in RAID as we would like to make sure that any site content you add will be risk-free all of the time. Using multiple hard drives in RAID for all of the main and backup servers permits us to offer fast and reliable Internet hosting service.
