5.1 PCIE topology description

MLU-X1001 accelerator uses 2 miniSAS HD interfaces to connect with the host server, and there are

2 PCIE switching chips to connect the PCIE devices inside.PCIE interconnection topology is shown as
follows:

Figure 5.1 PCIE Connection topology

PCIE signal rate is 16 Gbps, and the cable loss is controlled within 15 dB @8GHz. It is recommended

to use 1 meter cable with a diameter of 30 AWG.

The pins of the miniSAS HD connectors used by PCIE interfaces are defined as follows:
