[AusNOG] Cheapest half decent 10Gbps switch (for iSCSI only)

Mon Apr 20 18:28:51 EST 2015

How about Dell (Force10) S4810-{S|P}?

As long as you need layer 2 only, they're alright -- granted, they 
aren't optimized for storage networks, or anything.

Can be sourced pretty cheap in Ebay [0], I know of people using them 
without any issues for 10g layer 2 switching.

(They do support l3 too, actually -- but supposedly, this is not up to par.)
