Configuring an NVMe VROC module
This chapter describes configuring the NVMe VROC module on a rack server, blade server, or
compute module.
About the NVMe VROC module
Intel
®
Virtual RAID on CPU (Intel
®
VROC) is an upper-layer RAID solution specifically designed for
NVMe drives that are directly connected to the CPU. VROC NVMe RAID is available only when an
NVMe VROC module is installed.
The NVMe VROC module has a corresponding connector on the system board or main board. For
more information about the NVMe VROC module connector, see the user guide for the server.
NVMe VROC module can manage NVMe U.2 SSDs and NVMe M.2 SSDs. If NVMe M.2 SSDs are
installed on a RAID-MARVELL-SANTACRUZ-LP-2i storage controller, the NVMe M.2 SSDs are
managed exclusively by the controller.

RAID levels
The supported RAID levels vary by NVMe VROC module model. For more information, see H3C
Servers Storage Controllers Technical Specifications .
Table 2 shows the minimum number of drives required by each RAID level and the maximum
number of failed drives supported by each RAID level. For more information about RAID levels, see
"Appendix B RAID arrays and fault tolerance."
