Is a Mellanox ConnectX-3 10G NIC right for my home lab?
It can be a good fit if you have a free PCIe slot and SFP+ gear on the other end. The card uses an SFP+ cage, so it has no RJ45 jack.
- Cabling: plan for an SFP+ DAC cable or optical transceivers. Check the listing to see whether any are included.
- Bracket: confirm whether it ships with a full-height or low-profile bracket for your case.
- Drivers: check that your operating system or hypervisor supports ConnectX-3 before you buy.
- Slot: make sure your motherboard has a PCIe slot free.
