Intel® Server System R2000WF Product Family Technical Product Specification

4 port / 8 port PCIe* Switch to 8 x 2.5” Combo Backplane
The following information is applicable when PCIe signal 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
0 or 4
). Additional NVMe drives
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.
