2.10.3.2 4 port / 8 port PCIe* Switch to 8 x 2.5" Combo Backplane
The following information is applicable when PCIe signals to the 8x2.5" combo backplane are cabled from 4
or 8 port PCIe Switch add-in cards.

NVMe drive management sideband signals on the backplane are routed between drive connector sets:
(0,1,2,3) and (4,5,6,7)

In order to support NVMe drive management within a defined drive set, an NVMe drive MUST be
populated in the first drive connector of the given set (drive connectors
within the drive set must be populated in sequential order with no gaps between drive connectors.
 Combining NVMe drives and SAS/SATA drives within a defined drive set is NOT supported.
The following illustrations identify supported and unsupported drive populations associated with any
defined drive set of the 8x2.5" combo backplane when an Intel® VROC key is installed to the server board
and the PCIe source to the backplane is from an add-in PCIe Switch card.
