Intel® Virtual RAID on Chip (Intel® VROC) For NVMe*
Intel VROC enables NVMe boot on RAID and volume management (Intel RSTe 5.0 + Intel VMD).
Figure 41. Intel® VROC basic architecture overview
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 42.
Table 21 identifies available Intel VROC upgrade key options.
