Section 1 – Intel Virtual RAID On CPU (VROC)
Intel Virtual RAID on CPU (VROC) provides an enterprise RAID solution on platforms that support
Intel Volume Management Device (VMD).
Intel Volume Management Device (VMD) provides support for RAID on PCIe NVMe Solid State
Drives. Intel VMD’s can use a minimum of 4 PCIe lanes and a maximum of 16 PCIe lanes. There
can essentially be up to 4 NVMe SSD’s per Intel VMD.
Intel VROC, combined with Intel RSTe 5.0 and VMD, allows bootable RAID on PCIe NVMe SSDs
directly attached to the CPU PCIe lanes.
There are two types of VROC’s supported on Lenovo Workstations:
Intel Virtual RAID on CPU (VROC) – Basic
o Supports RAID 0, 1, and 10.
Intel Virtual RAID on CPU (VROC) – Premium
o Supports RAID 0, 1, 10, and 5.

Section 2 – VROC Support/Limitations by Platform
The screenshots below correlate with the diagrams above in Section 1 in regards to Intel VMD.
Refer to the motherboard diagrams in Section 3 to correlate the PCIe labels with the actual PCIe
slot locations.
