4 – Port PCIe Switch Card to 8 x 2.5” Combo Backplane
The following information is applicable when PCIe signal to the 8x2.5” combo backplane are cabled from a
4-port PCIe Switch add-in card.
NVMe drive management sideband signals on the backplane are routed between the following drive
connector set:
(4,5,6,7)
In order to support NVMe drive management within the defined drive set, an NVMe drive MUST be
populated in the first drive connector of the given set (drive connector
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 the defined drive set is
NOT
supported.
When an Intel® VROC key is installed to the server board, the following illustrations identify supported
(√)
and unsupported
(X)
drive populations associated with the defined drive set when the PCIe source to the
backplane is from an add-in PCIe Switch card.
