I care about the money, but I also want to use the switch for a while, so have it "future-proof" to an extend is important. For me power consumption is also important and to have a balance between that and what requirements I have. I tend to think big and then do not use all of it. Trusting the RUCKUS documentation the difference is 21W idle vs 50W idle for the PoE models, which translates into $33 additional cost per year for where I live.@thimplicity
both ICX6450-24P and 7250-24P are nice. Just keep in mind that 6450-24P is like half the price of a 7250-24P (24 port SKUs are usually more expensive on the second hand market, because they need less power).
If you don't care about money, take the 7250-24P. Otherwise you're most likely going to be happy with the 6450-24P, except if you're planning to do weird network stunts... But also, if you were planning weird networks stunts, you probably wouldn't be asking whether you should choose the 7250 or 6450
I do not think I am planning any stunts beyond VLANs and inner-VLAN routing, which requires L3 capabilities, that the other contenders in my case (Ubiquiti and Mikrotik) do not seem to have to the extend the Brocades do.
Another challenge I need to think about is space/size and heat dissipation. My media enclosure that will house the PoE switch is 14 inches wide and the 7250 is 11 inches and the 6550 9.5 inches deep. I think I will continue to use the fans you can see below, but cut a whole in the door and have the bottom one suck "cold" air in and the top one push warm air out. See a picture of the current setup (also with an ICX switch) below:
