: IBTA v1.3
a
Auto-Negotiationa: 1X/2X/4X SDR (2.5Gb/s per lane), DDR (5Gb/s per lane), QDR (10Gb/
s per lane), FDR10 (10.3125Gb/s per lane), FDR (14.0625Gb/s per lane), EDR (25Gb/s per
lane) port
a. The ConnectX-5 adapters supplement the IBTA auto-negotiation specification to get better bit error rates and
longer cable reaches. This supplemental feature only initiates when connected to another Mellanox InfiniBand
product.

Ethernet
1/10/25/40/50/100 Gb/s
PCI Express Gen3:
SERDES @ 16.0GT/s, 16 lanes (2.0 and 1.1 compatible)
Note: PCIe 3.0 x16 bus can supply a maximum bandwidth of 128Gb/s only (=16 * 8GT/s,
including overhead), and therefore cannot support 200Gb/s when both network ports of
MCX556A-ECAT run at 100Gb/s.
