Overview of Intel® Virtual RAID on CPU (Intel® VROC)


Product Information & Documentation



Intel® Virtual RAID on CPU (Intel® VROC) is an enterprise, hybrid RAID solution specifically designed for NVMe*-based Solid State Drives (SSDs) connected directly to the CPU.

Intel VROC is made possible by the new CPU feature Intel® Volume Management Device (Intel® VMD), a new hardware architecture on Intel® Xeon® Scalable Processors. Intel VMD enhances the 48 preexisting PCIe* lanes for dependable NVMe connections.

The biggest advantage of Intel VROC is the ability to directly connect NVMe-based SSDs to the new Intel® Xeon® Scalable processor PCIe* lanes, then make RAID arrays using those SSDs without using a RAID host bus adapter (HBA). As a result, Intel VROC unleashes NVMe SSD performance potential without the complexity and power of a traditional hardware RAID HBA. In this way, Intel VROC was designed specifically for NVMe SSDs, and is positioned to appropriately support this technology and help transition the market to these faster drives.

Key benefits of Intel VROC are:

  • Use NVMe drives to their full potential
  • Fewer hardware queues
  • Bootable RAID
  • Host Insert/Surprise removal
  • Closes RAID 5 write hole
  • LED Management
  • Cost-effective and simple
