My goal:
I'm currently in the process of migrating from VMware to Proxmox. Bought two almost new SFF boxes (Lenovo ThinkCentre M70S SFF) for my new base infra and want to connect them to my QNAP QSW-M1208-8C at 10GBit through SFP+.
Research done:
Next to some searching on the internet I was looking for Intel X520-DA2's with SFP+ before I found out you could find adapters from QSFP+ to SFP+ (source: https://www.servethehome.com/using-a-40gbe-qsfp-nic-with-a-10gbe-switch-sfp/ , https://forums.servethehome.com/index.php?threads/mellanox-qsfp-to-sfp-adapter-10.26005/). Also looked at Intel X710's, but they are more expensive. I prefer Intel or Mellanox NICs.
Situation:
I still have some Mellanox ConnectX-3 MCX354A-QCBT flashed to MCX354A-FCBT with QSFP+ on hand with low profile brackets. They aren't supported in newer VMware releases anymore, but still seem to be in Linux. Have done OFED installations before. Looks like the QSFP+ to SFP+ adapters are an option to keep the cost down.
For cables I was looking at: Cisco SFP-H10GB-CU3M Compatible 10GBASE-CU SFP+ DAC Twinax Cable - FS.com Europe
Disclaimer:
Could have posted this in the Linux section, but seems to me more like a networking thing. Mod can move it as needed.
Question:
Before I go buying other cables or even other NICs, any advice/experiences/...? Am I missing something? Am I on the right track? Or am I cheaping out?
