Any thoughts on the FS.COM's S3900-24F4S? I am close to pulling the trigger for a core switch purpose as I am unaware of similarly priced alternatives with 4xSFP+ and plenty of SFP ports (the wiring in the house is entirely fibre optics - with the exclusion of WiFI APs and security cameras). Two things that are very important - inter-VLAN routing at 10 G speed and DHCP relay. I get the feeling that is exactly where MikroTik's switches fall short - they are awesome as L2 switches, but the moment you ask anything else, my understanding is the performance falls precipitously.
(side note: PoE side of things will be handled by a Cisco 3560G, so I don't need PoE capability).
EDIT: If CRS328-4C-20S-4S+RM supports inter-VLAN routing at 10G speeds and DHCP relay, I'd be probably buying that....but I cannot find that info yet.
