Will this ConnectX-4 100GbE adapter work in my server or workstation?
That depends on your slot, OS and cabling, so check a few things first.
- Make sure your motherboard has a suitable PCIe slot with enough lanes for full bandwidth.
- Plan for QSFP28 cables or transceivers, and check whether any are included.
- Ask the seller about the firmware version and whether the port is set to Ethernet or InfiniBand mode.
- Make sure your case has good airflow, because high-speed NICs run warm.
