Intel® Virtual RAID on CPU (Intel® VROC) is an enterprise RAID solution that unleashes the performance of NVMe* SSDs. Intel® VROC is enabled by a feature in Intel® Xeon® Scalable processors called Intel® Volume Management Device (Intel® VMD), an integrated controller inside the CPU PCIe root complex. NVMe SSDs are directly connected to the CPU, allowing the full performance potential of fast storage devices to be realized. Intel® VROC enables these benefits without the complexity, cost, and power consumption of traditional hardware RAID host bus adapter (HBA) cards placed between the drives and the CPU.

The following document is a quick start guide of using the FIO* benchmarking tool for systems containing Intel® Xeon® Scalable Processors with Red Hat Enterprise Linux*. This document includes specific steps for testing NVMe* SSD RAID arrays on Intel® Volume Management Device (Intel® VMD) enabled PCIe* lanes with Intel® VROC.

What you should know about the Intel® VROC package
  • System vendors may customize the Intel® VROC package for their specific platforms. Reference your OEM for a full list of available feature sets. If any of the information in this document conflicts with the support information provided by the platform OEM, the platform documentation and configurations take precedence.
  • This performance evaluation guide includes specific configurations (including the Intel® VROC package version used) that should be followed to achieve similar results. Differences in the system configuration may give different results from the ones described in the document.
