3. When installing PCIe* SSD NVMe drives, connect one end of the OCuLink* data cables to the
OCuLink* connectors corresponding to the used ports on the backplane and the other end to the
OCuLink* connectors on the server board. An example of the OCuLink* data cable is shown
below.

NVMe* Drive Population Rules for Intel® VROC
In order to support NVMe RAID and NVMe Management features, the optional Intel® VROC Key must be
installed on to the server board. With the Intel VROC key installed, specific drive population rules exist and
must be followed for proper support of the NVMe management features.
The backplane can support PCIe interfaces from the onboard OCuLink connectors on the server board,
and/or optional add-in Intel Tri-Mode RAID modules and/or PCIe Switch cards. When cabling the PCIe
interfaces from two different PCIe interface sources to the backplane, the cables from each source must be
connected in defined drive sets of four (0,1,2,3) & (4,5,6,7) as shown in the following diagrams.
Note: OCuLink connectors on the server board (one or all) routed to the backplane is considered a single
source.
Routing OCuLink cables from two or more PCIe sources to a defined drive set is not supported.
