Intel® Virtual RAID on CPU (Intel® VROC) Configuration Guide for VMware* ESXi* Linux* Virtual Machines Direct Assign


Install & Setup



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 configuration guide provides the information required to setup a Red Hat Enterprise Linux* (RHEL) Virtual Machine (VM) drive assignment using Direct Assign (DA) in VMware* ESXi*.

What you should know about the Intel® VROC package
  • System vendors may customize the Intel® VROC package for their specific platforms. Refer to 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.
  • The Intel® VMware* ESXi* related software does not provide full Intel® VROC RAID features, so it is labeled as Intel® Volume Management Device (Intel® VMD) Driver for VMware* ESXi*.
