The DPU incorporates 16GB @ 3200MT/s single DDR4 channel, 64bit + 8bit ECC, solder-
down memory.
NC-SI Management Interface
The DPU enables the connection of a Baseboard Management Controller (BMC) to a set
of Network Interface Controller (NICs) to enable out-of-band remote manageability. The
NC-SI management is supported over RMII and has a connector on the DPU. For
connecting to the NCSI RBT interface on the 20 or 30-pin connector, a customized cable is
needed based on the NC-SI Management Interface pinouts.
The below table specifies the maximum trace lengths on the board per board type.
Please take the maximum trace length on the board into consideration in your design.
