Enabling Intel® VMD 2.0 for NVMe* Support
For installed NVMe* devices to use the Intel® VMD features in the system, Intel® VMD must be enabled on the
appropriate processor PCIe* root ports in BIOS Setup. By default, Intel® VMD support is disabled on all
processor PCIe* root ports in BIOS Setup.
The following table provides the PCIe* port routing information for the server board PCIe* SlimSAS
connectors.

Intel® Virtual RAID on Chip (Intel® VROC) for NVMe*
Intel® VROC 7.5 supports the following:
•
I/O processor with controller (ROC) and DRAM.
•
Protected write-back cache
–
software and hardware that allows recovery from a double fault.
•
Isolated storage devices from operating system for error handling.
•
Protected R5 data from operating system crash.
•
NVMe* SSD hot plug and surprise removal on processor PCIe* lanes.
•
LED management for PCIe* attached storage.
•
RAID/storage management using Representational State Transfer (RESTful) application programming
interfaces (APIs).
•
Graphical user interface (GUI) for Linux*.
•
4K native NVMe* SSD support.
Enabling Intel® VROC 7.5 support requires installation of an optional upgrade key on the server board as
shown in
