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.  \nIntel VROC, combined with Intel RSTe 5.0 and VMD, allows bootable RAID on PCIe NVMe SSDs directly attached to the CPU PCIe lanes.  \nThere are two types of VROC’s supported on Lenovo Workstations:  \n􀁸 Intel Virtual RAID on CPU (VROC)– Basic  \no Supports RAID 0, 1, and 10.  \n􀁸 Intel Virtual RAID on CPU (VROC)– Premium  \no Supports RAID 0, 1, 10, and 5.  \nPremium  \nSee Intel documentation for more details on Intel Virtual RAID On CPU (VROC):  \n[https://www.intel.com/content/www/us/en/support/memory-and-storage/ssd](https://www.intel.com/content/www/us/en/support/memory-and-storage/ssd)software/000024498 . html  \nThinkStation P720  \nThinkStation P920  \nSection 2 – VROC Support/Limitations by Platform  \nThe 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.  \nThinkStation P720  \n􀃎 “CPU 0 Port 2”  \no PCIE Slot 2 (x16 slot)  \n􀃎 “CPU 0 Port 3  \no M.2 Slot 1 (x4 slot)  \no M.2 Slot 2 (x4 slot)  \no PCIE Slot 3 (x8 slot)  \n􀃎 “CPU 1 Port 1”  \no PCIE Slot 1 (x16 slot)  \nThinkStation P920  \n􀃎 “CPU 0 Port 1”  \no PCIE Slot 3 (x16 slot)  \n􀃎 “CPU 0 Port 3  \no M.2 Slot 1 (x4 slot)  \no M.2 Slot 2 (x4 slot)  \no PCIE Slot 2 (x4 slot)  \no PCIE Slot 4 (x4 slot)  \n􀃎 “CPU 1 Port 1”  \no PCIE Slot 8 (x16 slot)  \n􀃎 “CPU 1 Port 2”  \no PCIE Slot 6 (x16 slot)  \n􀃎 “CPU 1 Port 3”  \no PCIE Slot 7 (x16 slot)  \nLevels of Support:  \n􀁸 BOOTABLE RAID on NVMe SSDs – maximum of four NVMe SSDs.  \no Cannot span across multiple Intel VMD domains.  \n􀁸 DATA RAID on NVMe SSDs  \no Can span across multiple Intel VMD domains.  \n􀁸 Spanning across CPU’s.  \no Not recommended as it could result in performance degradation.  \n􀁸 UEFI  \no Does not support nor provide a Legacy Option ROM.  \n􀁸 Three (3) Intel Volume Management Device (VMD) domains per single CPU.  \n􀃎 For Debian and Ubuntu Linux based operating systems, VMD mode is NOT supported; therefore, NVMe PCIe drives need to be set up as PCIE mode.  \n􀃎 For RedHat Linux based operating systems, VMD mode support is limited. RHEL 7.3/7 .4 or equivalent operating systems can support VMD mode with a proprietary Intel  \nRSTe/VMD driver. See “P520c-P520-P720-P920 RHEL 7 Installation” whitepaper for step-by-step instructions on how to get this to work.  \nSection 3 – How to Install the VROC Device  \nRefer to the motherboard diagrams below for the location of the VROC header on the motherboard.  \nP720  \nP920  \nPCIE Slot 1  \nPCIE Slot 2  \nPCIE Slot 3  \nPCIE Slot 4  \nPCIE Slot 5  \nPCIE Slot 6  \nPCIE Slot 6  \nPCIE Slot 7  \nPCIE Slot 8  \nM.2 Slot 1 & 2  \nM.2 Slot 1 & 2  \nPCIE Slot 1  \nPCIE Slot 2  \nPCIE Slot 3  \nPCIE Slot 4  \nPCIE Slot 5  \nSection 4 – How to Configure the VROC Device  \nPlease see the following steps to configure VROC.  \n1. Boot into BIOS by pressing the function F1 key at the “Lenovo” splash screen.  \n2. Select “Setup” from the screen indicated below.  \n3. Select “Advanced” (left) and “Intel VMD technology” (right) .  \n4. Enable the appropriate CPU x Port y based on where the NVMe SSDs are installed in the system.  \n***See Section 2 above for specific platforms.  \n5. Set the appropriate slots where the NVMe SSDs are installed to “VMD”.  \n***","cbCaiqbTwhUHQTvv","https://ap.wps.com/l/cbCaiqbTwhUHQTvv","pdf",1640807,15,"English","# SECTION 1 – Intel Virtual RAID On CPU (VROC) [OVERVIEW]\n# SECTION 2 – VROC Support/Limitations by Platform\n# SECTION 3 – How to Install the VROC Device\n# SECTION 4 – How to Configure the VROC Device\n# SECTION 5 – How to Create the M.2 RAID Array\n# SECTION 6 – Document Revision History","[{\"question\":\"What RAID levels are supported by VROC Basic and VROC Premium?\",\"answer\":\"VROC Basic supports RAID 0, 1, and 10.
