Warnings
Heed safety instructions: Before working with your server product, whether you are using this guide or any
other resource as a reference, pay close attention to the safety instructions. You must adhere to the
assembly instructions in this guide to ensure and maintain compliance with existing product certifications
and approvals. Use only the described, regulated components specified in this guide. Use of other
products/components will void the UL listing and other regulatory approvals of the product and will most
likely result in noncompliance with product regulations in the region(s) in which the product is sold.
System power on/off: The power button DOES NOT turn off the system AC power. To remove all power
from the system, you must unplug the AC power cord from the wall outlet. Make sure the AC power cord is
unplugged before you open the chassis, add, or remove any components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the server and disconnect the power cord,
telecommunications systems, networks, and modems attached to the server before opening it. Otherwise,
personal injury or equipment damage can result.
Installing or removing jumpers: A jumper is a small plastic-encased conductor that slips over two jumper
pins. Some jumpers have a small tab on top that you can grip with your fingertips or with a pair of fine needle
nosed pliers. If your jumpers do not have such a tab, take care when using needle-nosed pliers to remove or
install a jumper; grip the narrow sides of the jumper with the pliers, never the wide sides. Gripping the wide
sides can damage the contacts inside the jumper, causing intermittent problems with the function controlled
by that jumper. Take care to grip with, but not squeeze, the pliers or other tool you use to remove a jumper,
or you may bend or break the pins on the board.
Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, boards, and other parts. We
recommend that you perform all procedures in this chapter only at an ESD workstation. If one is not
available, provide some ESD protection by wearing an anti-static wrist strap attached to chassis ground, any
unpainted metal surface on your server when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely sensitive to ESD. Hold
boards only by their edges. After removing a board from its protective wrapper or from the server, place the
board component side up on a grounded, static-free surface. Use a conductive foam pad if available but not
the board wrapper. Do not slide board over any surface.

1. Overview
Intel® VROC (VMD NVMe RAID) is a powerful, reliable, and affordable hybrid RAID solution that uses the built-
in processor’s Volume Management Devices (VMD) and Intel® RSTe drivers to create and manage RAID
configurations. Intel® VROC is only available when the system is configured for UEFI boot mode. To enable
the Intel® VROC, a hardware key must be inserted onto the motherboard, and the appropriate processor
Virtual Management Devices must be enabled in BIOS Setup.
Intel® VROC provides added performance and reliability for supported systems equipped with NVM
Express* (NVMe*) drives to enable an optimal enterprise storage solution. Intel® VROC offers data
protection by enabling RAID in a pre-boot environment that can be used in operating systems like Microsoft
Windows*, Red Hat Linux* and SUSE Linux*.

2. Preparing Server Hardware and Drivers
2.1 Server System
Intel recommends that the server system be installed with the latest firmware package that includes the
BIOS, ME, FD, BMC, and FRUSDR utility. The best way to achieve this is to download and install the latest
published System Update Package (SUP) corresponding to the motherboard being used, which may be
found at the Intel Download Center. In the search box near the top of the page, type in the motherboard
model number (e.g., S2600WFT), then click the magnifying glass icon. Set the "Download Type" dropdown to
"BIOS" or "Firmware" (depending on which option is available), and the available SUP versions will be
displayed. The specific package contains installation instructions.
2.2 Intel VROC Hardware Key
In order to enable Intel® VROC, a Hardware Key must be installed on the Intel® motherboard. There are three
separate keys supporting different RAID levels:
•Intel® VROC Standard (MM#951605): Enables RAID levels 0, 1 and 10. Different NVMe drive
manufacturers are supported. Consult the THOL for a full list.
•Intel® VROC Premium (MM#951606): RAID levels 0, 1, 10 and 5. Different NVMe drive manufacturers
are supported. Consult the THOL for a full list.
•Intel® VROC Intel SSD Only (MM#956822): Enables RAID levels 0, 1, 10 and 5 but only the Intel®
NVMe drives are supported.
Refer to the corresponding system TPS document of your Intel® motherboard for VROC Hardware Key
installation instructions.
2.3 NVMe* drives
Intel® VROC only supports the U.2 form factor NVMe drives connected through supported backplanes. Intel
recommends that the drives are of the latest firmware version, and makes available the Intel* SSD Data
Center Tool utility in order to update the firmware on Intel® SSD DC family drives. Other vendors provide
similar tools.
The Intel® SSD Data Center Tool runs on top of Windows* or Linux* operating systems and can be used when
the drives are behind the VMD controllers as well as after a RAID configuration has been created. For more
detailed information on how to update the firmware on the Intel NVMe drives using the Intel* SSD Data
Center Tool, refer to Appendix B.
2.4 PCIe switches and retimers
Intel recommends having the latest firmware installed on the PCIe switches and ensuring that the BMC is
aware of such cards. If the SUP (mentioned in Section 2.1) was applied after the cards were installed, then
the BMC is already aware. In other cases, or if the cards were moved to a different PCIe slot, the BMC needs
to be made aware of such changes by booting the system into the EFI shell and running the
sdr_update_noprompt.nsh script. This script is part of the SUP.
When PCIe switches are used, it’s the switch firmware who handles the drive LED management, in other
words, who handles the locate, fault and rebuild LEDs. LED management is handled in a different way when
VMD is enabled than when VMD disabled.
LED management is set to VMD disabled by default but since VMD must be enabled in order to have Intel®
VROC, it must be set to VMD enabled the first time the PCIe switch is installed. This setting is persistent, so
the it only needs to be set once. Intel provides an LED Management toggle tool to change this setting.

Intel® VROC Quick Configuration Guide
6
The Firmware Package and LED Mode Toggle Tool for Intel® PCIe* Switches includes both, the firmware
package and the LED Management toggle tool. The package has readme files with instructions for each
component.
Note: Not configuring LED management correctly will make the locate and fault drive LEDs not to work and
make difficult to identify and replace a faulty drive.
2.5 Drivers.
The Intel® VROC solution has two driver components: the pre-boot, or UEFI driver, and the OS driver. The
UEFI driver is embedded in the system BIOS and is referred to as the RSTe NVMe UEFI driver, while the OS
driver must be loaded at the OS installation time and is referred to as the RSTe OS driver; both contain
version numbers. The OS driver version can be equal or later than the UEFI driver version but not vice versa,
excepting for the Linux OS. If the system BIOS version is updating while the prior BIOS version has a newer
RSTe NVMe UEFI driver embedded, the RSTe OS driver must be updated first.
Note: On a system with the Windows* OS installed and an Intel® VROC virtual drive present, the Windows*
RSTe OS driver version must not be prior to the RSTe NVMe UEFI driver version, otherwise unexpected
behavior may happen.
The RSTe OS driver can be found on the Intel Download Center. Enter vroc into the field near the magnifier
icon, and it will show both Windows and Linux driver links.
The RSTe NVMe UEFI driver version embedded in the BIOS is documented in the corresponding BIOS
Release Notes for the SUP Package, look at the “BIOS COMPONENTS/CONTENTS” section.
Below is an example of how the RSTe NVMe driver version is documented in the Release Notes file.
Figure 1. RSTe NVMe release note documentation style
For the UEFI driver version in the above example, the 5.4 or later RSTe OS driver must be used, but nothing
earlier than 5.4 would be supported.

3. Intel® Volume Management Device (Intel® VMD)
Intel® VMD is a new feature introduced with the Intel® Xeon® processor Scalable family. This native feature
provides RAID support for NVMe* drives directly connected to the processor’s PCIe* lanes through a
supported backplane. This section describes how to enable and configure this functionality.
Each member of the Intel® Xeon® processor Scalable family has three Intel® VMD domains (numbered one,
two, and three). Each Intel® VMD domain manages 16 PCIe* lanes divided into four Intel® VMD ports (named
A, B, C, and D) consisting of four PCIe* lanes each. Some of these Intel® VMD ports are routed to specific
risers and slots in the system, while other Intel® VMD ports are routed to specific chipset uplinks, SAS
modules, or onboard Oculink connectors. This routing is fixed (non-configurable); please refer to the relevant
motherboard's Technical Product Specification for details on this routing.
Note: Intel® VMD ports routed to specific chipset uplinks cannot be used for Intel® VROC (VMD NVMe RAID)
configurations.
There are two different ways to connect NVMe* drives to Intel® VMD ports:
1. NVMe* drives connect directly to VMD ports in a 1:1 fashion when using the onboard Oculink* ports
or by using PCIe* retimers. Each NVMe* drive then uses four dedicated PCIe* lanes, providing full
bandwidth to each drive.
2. Several NVMe* drives connect to one VMD port by using either 8x4 or 8x8 PCIe* switches. Eight PCIe*
lanes are then shared by the NVMe* ports, providing limited bandwidth to each drive.
The RAID volume may be used as a bootable drive only if all drives in the RAID volume are connected to a
single Intel® VMD domain. It is possible to create RAID volumes spanning multiple Intel® VMD domains,
however such RAID configurations cannot be made bootable.
3.1 Enabling the Intel® VMD ports
By default, all Intel® VMD ports are disabled in BIOS Setup. For Intel® VROC (VMD NVMe RAID), the
appropriate Intel® VMD ports must be enabled by selecting the following menu options in order after
entering BIOS Setup:
1. Advanced
2. PCI Configuration
3. Volume Management Device

Intel® VROC Quick Configuration Guide

Figure 2. Steps to enter the Volume Management Device Port Window
Example A: If an R2000WF system is being used and four NVMe* drives are being connected to the four
onboard Oculink connectors, VMD ports 3A, 3B, 3C and 3D must be enabled.
Figure 3. VMD port Example A

Intel® VROC Quick Configuration Guide

Example B: If an R2000WF system is being used and eight NVMe drives are connected through an 8x8 PCIe
switch in slot one on riser two, VMD ports 1C and 1D must be enabled.
Figure 4. VMD port Example B
Note: If a retimer is used, a x16 slot is required and all four VMD ports must be enabled. Refer to the
corresponding motherboard’s TPS for supported riser and slot combinations.
Once the appropriate Intel® VMD ports are enabled, the system must be rebooted for the changes to take
effect.

Intel® VROC Quick Configuration Guide

4. Creating Intel® VROC (VMD NVMe RAID) volumes
This section explains how to create RAID volumes using Intel® VROC by using the HII Configuration Utility in a
pre-boot environment. Intel® VROC RAID volumes can be used to store data and/or to install an operating
system.
4.1 Accessing the Intel® VROC (VMD NVMe RAID) HII Configuration Utility
Intel® VROC HII is the utility used to create and manage RAID configurations using NVMe* drives in a pre-boot
environment. The proper Intel® VMD ports must be enabled (and the system rebooted) to have the Intel®
VROC (VMD NVMe RAID) HII visible.
Access the HII configuration utility by entering BIOS Setup and selecting the following menu options in order:
1. Advanced
2. PCI Configuration
3. UEFI Option ROM Control
4. Intel® Virtual RAID on CPU
Figure 5. Steps to access the Intel® VROC HII configuration utility
4.2 Creating RAID Volumes Using the Intel® VROC (VMD NVMe RAID) HII
Configuration Utility
After preparing the server hardware (see Section 2) and enabling the appropriate VMD ports, the RAID
volumes can be created. The following steps demonstrate the creation of RAID volumes within the Intel®
VROC HII configuration utility:

Intel® VROC Quick Configuration Guide

1. After selecting Intel® Virtual RAID on CPU, the Intel® VROC (VMD NVMe RAID) HII menu screen
appears, showing the installed Upgrade Key and the configured Intel® VROC RAID volumes (if any).
2. Select All Intel® VMD Controllers. The Intel® VROC managed VMD menu will appear showing all
Intel® VMD controllers with their corresponding NVME* drives.
Figure 6. Intel® VROC Managed VMD menu
3. Select Create RAID Volume. The Create RAID Volume menu will appear.
Figure 7. Create RAID Volume menu

4. Fill in the volume name (optional), then select the desired RAID level. Depending on the number of
drives and upgrade key installed, the available options are:
•RAID0
•RAID1
•RAID10
•RAID5
Select whether to span drives across different VMD controllers, then select the drives that will be used for
the chosen RAID level. The resulting capacity of the volume defaults to the maximum available for the
selected drives but may be decreased by the user.
Note: Spanned RAID volumes cannot be made bootable.
Figure 8. Completed Create RAID Volume menu
5. Once the required fields are populated, select Create Volume.
6. Once the RAID volume is created the Intel® RSTe HII main menu displays the newly created volume.
