QNAP QSW-M1208-8C

[Enquiries]

My current server has a 40GB Qsfp+ NIC. I plan to use a Qsfp to 4 x Sfp+ breakout cable and would like to get the above mentioned QNAP QSW-M1208-8C, and then possibly aggregate a few of those sfp+'s. My question is, is there any reason that wouldn't work? Second question, can i use this switch for both LAN traffic as well as for regular ethernet traffic, or would it be better to keep individual devices connected to the net as they currently are and use this switch strictly for LAN traffic?
Bear with me please as I am a rookie when it comes to 10gb+ networking Im about ready to pull the trigger on this switch, however I would like confirmation that it will work for my intended purpose.

This is a managed switch which allows link aggregation. Everything can be connected via switch, no need to make separate loops.
Link aggregation in Windows might require server OS. But it is easier to get 10gbe card instead of linking together slower LAN ports.
