Intel® Server System R2000WF Product Family Technical Product Specification
7.4.3 Intel® Virtual RAID on Chip (Intel® VROC) for NVMe*
Intel® Virtual RAID on Chip (Intel® VROC) enables NVMe* boot on RAID and volume management (Intel® RSTe
5.0 + Intel® VMD)
Intel® VROC supports the following:
 I/O processor with controller (ROC) and DRAM.
 No need for battery backup / RAID maintenance free backup unit.
 Protected write back cache – software and hardware that allows recovery from a double fault.
 Isolated storage devices from OS for error handling.

Protected R5 data from OS crash.
 Boot from RAID volumes based on NVMe SSDs within a single Intel VMD domain.
 NVMe SSD hot plug and surprise removal on CPU PCIe* lanes.
 LED management for CPU 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 support requires installation of an optional upgrade key on to the server board as
shown in Figure 70.
Table 63 identifies available Intel VROC upgrade key options.
