F1-Series linecard has been a part of Nexus 7000 product family for a while now but it has not gained much popularity due to its limitation, mainly on the lack of L3 routing capability and FEX support. Yet, F1 linecard is the only linecard that supports Fabricpath, but unless Fabricpath is one of the requirements, you might be better off with the older M1 series. However, this is about to change. Cisco has recently come out with a new F2 series linecard that overcomes a lot of drawbacks on the F1.
