Hi all, I have a pair of Mellanox MCX353A-FCBT coming my way.
I want to setup a point to point (no switch) 40Gbe link between a workstation and server.
I was digging through documentation and came across this: https://www.mellanox.com/related-docs/prod_cables/PB_MC22061xx-00x_MC22071xx-0xx_MC22101xx-00x_MCP170L-F0xx_MCP1700-B0xxx_56Gbps_QSFP+_DAC.pdf
I am kinda confused about the description column.
Do some cables support VPI and Infiniband, and others support ethernet only?
For example:
MC2210126-005 Mellanox® passive copper cable, ETH 40GbE, 40Gb/s, QSFP, 5m
If I buy this and setup 40GbE can I not do infiniband with the same cable?
MC2207126-004 Mellanox® passive copper cable, VPI, up to 56 Gb/s, QSFP, 4m
If I buy this can I do ethernet via VPI but not infiniband?
MC2206125-007 Mellanox® passive copper cable, IB QDR, 40 Gb/s, QSFP, 7m
If I buy this am I relegated to only infiniband?
Thanks, and sorry if this is obvious... I am very new to the hardware here.
