AMD Pensando DSC2-100G Hardware Overview
The cards in our Dell PowerEdge R7615 servers are full height AMD Pensando DSC2-100G. We are not exactly sure about the Pensando naming, but the original 25GbE cards were DSC-25G. The new card seems to be DSC2 (Pensando used to call these Distributed Service Cards or something similar) with 2 for 2nd generation Elba architecture.
The cards have a PCIe Gen4 x16 interface on one side and two QSFP28 100GbE ports on the other side.
The heatsink is significant, and because this is STH, we also have a version without the heatsink so you can see the memory atop the SoC.
On the back side of the card, we get additional memory, an AMD Xilinx Artix 7, and then the NAND storage.
Here is a view of the two 100GbE QSFP28 cages without the heatsink. One can see there are fairly substantial heatsinks on the cages, but nowhere near what we are seeing in the 400GbE generations.
Here is the opposite side of the NIC where airflow enters the heatsink in the PowerEdge R7615 test servers.
That white connector is for the management cable. We can see it easily in this edge shot.
We can also see just how large the 7nm Elba DPU chip is behind it.
Here is the PCIe Gen4 x16 connector side.
Our Canon lens being used to prop up cards also allowed us to get this view between the heatsink and the card.
That is the DSC2-100G option, but there is also a 25GbE option.
