Is Intel® Virtual RAID on CPU (Intel® VROC) a Software or Hardware RAID Solution?

BUILT IN - ARTICLE INTRO SECOND COMPONENT

Summary

Description of key elements that make Intel® VROC a hybrid RAID solution

Description

Can Intel VROC be considered as a software RAID solution because it does not need extra hardware?

Resolution

Intel® Virtual RAID on CPU (Intel® VROC) is a hybrid RAID solution.

It has attributes like hardware RAID because of the key silicon feature called Intel® Volume Management Device (Intel® VMD), which is offered with the new Intel® Xeon® Scalable processors. Intel VROC utilizes Intel VMD to aggregate NVMe* SSDs allowing bootable RAID.

Intel VROC also has attributes like software RAID. For instance, it uses some of the CPU cores to calculate the RAID logic.

Because of this combination of software and silicon, Intel VROC is called a hybrid RAID solution.
