I am new to 10gbe, and was able to direct connect 2 test severs using Connectx-2 cards and SPF+ cable successfully, but when connected to the SPF+ port on my 3Com switch, it shows the cable unplugged. This is my test set up.
Server 2012 R2, all updates installed. HP DL380 G7s.
Switches: 3Com 2948- SFP-Plus x4 SFP Connections. Cisco Passive Copper 10gbe Cable, testing working
Mellanox HW Card settings: Eth, all other settings at defaults
Information: Driver 4.80.10388.0 Firmware 2.9.1200 Part# MNPA19-XTR
I understand when using Infiniband it requires a Subnet Manager, but does this also apply in Ethernet mode?
Is a special cable required? or special driver settings?
Thanks, and look forward to playing with these.
