Purpose
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 user guide provides the information required to manage Intel® VROC RAID volumes using the mdadm application in Linux*, including:
- Product overview and functionality
- Installation process
- RAID management
- LED management
Descriptions
This document provides the steps for users to set up Intel® Virtual RAID on CPU (Intel® VROC) with the Ubuntu server. Ubuntu LTS servers have inbox drivers including mdadm and ledmon user-space utilities and kernel md, VMD drivers to enable Intel® VROC functionalities.
The Desktop versions of Ubuntu* are not validated for Intel® VROC, detailed as the below link
Defect Submission Support
For Ubuntu-related issues, please get in touch with Ubuntu support at https://ubuntu.com/support
For silicon/platform-related issues, Intel will accept and process issues reported by customers via the Intel Premier Support (IPS) portal.
Please use the Intel Premier Support (IPS) tool to submit an issue. Your local FAE can provide you with the requirements to enable the submission of an IPS issue.

Audience
For the engineers with experience on Advantech BMC's platforms with basic knowledge of remote access.
Prerequisite
1. Hardware: Intel Xeon Scalable CPU with BIOS support Intel VROC
2. Supported Browsers:
• Chrome's latest version.
• IE 11 and above.
• Firefox (with limited support).
3. Intel® Xeon® Scalable Platform family with Intel® C620 series chipset
Procedure
-
VROC RAID volume can be created in the Hardware. The Ubuntu installer can recognize the RAID volume as the installation target during the installation.
-
BIOS -> Post & Boot -> Enabled CSM Support and Keep "UEFI" type
- Boot to the Ubuntu installer in the “GRUB” and start to install Ubuntu
- During installation. Afterward, the VROC RAID volume device can be selected as the installation target.
- Select the VROC RAID from the "Post & Boot" Option
- Boot from UIbuntu Server
- VROC Status Check in Ubuntu Server
NOTE
-
Install ledmon tool for LED management from the Ubuntu repository
Note: Ubuntu offers ledmon from two repositories: bionic universe (ledmon 0.79) and bionic-updates universe (ledmon 0.90), we recommend a higher version. Bionic-updates universe should be enabled (by default it is).
#sudo apt install ledmon
#sudo ledmon - -version (check the ledmon installation)
- Ledmon is not launched by default when the system reboots, Create the file “/etc/systemd/system/ledmon.service”
#sudo vi /etc/systemd/system/ledmon.service (input the content following) [Unit]
Description=Enclosure LED Utilities
[Service] ExecStart=/usr/sbin/ledmon Type=forking
[Install]
WantedBy=multi-user.target
#sudo systemctl start ledmon.service
#sudo systemctl status ledmon.service
#sudo systemctl enable ledmon.service
