I enjoy buying used enterprise gear because a) it's cheaper than most other networking gear and 2) because it's enterprise I usually don't have to worry about overpowering the equipment with my home setup.
I'm looking at used 10gb switches on ebay for less than $200 but find that even though there are plenty of options they're either vastly too complicated, like blade switches, or require licenses and I'm not that familiar with enterprise equipment to know if I'll need a license which I don't want to pay for or deal with.
I've looked at the dell z9000, dell force10 s4810p and the cisco n5k-c5548p which I understand needs a license so will probably be crossed out. I know that Mikrotik has some decently priced 10gb switches for $200~ that has 8 sfp+ ports, so that's a last option I suppose.
Does anyone know anything about the z9000 or the s4810p? Any recommendations for other cheap enterprise 10gb switches? I liked that the dell units also had some ports for 40gb but the 10gb is more realistic for now. I also like dell networking in general.
You might want to look at Brocade ICX6650. Sometimes they're available for very little money.
Depending ahow many SFP+ ports you need, an ICX6610 might also works (8x SFP+ + 8x10G via QSFP + 2x 40G QSFP)
