Peter, Network visibility wasn't mentioned as a requirement, but it is worth considering since the ToR switches are the best place monitor server network I/O, tunneled traffic (VxLAN, GRE etc), storage (iSCSI, FCoE, HDFS etc).
The Nexus 5548 switch does not include monitoring (i.e. no NetFlow/sFlow). The Nexus 3048, along with all the other 10G ToR switches so far mentioned on this thread, supports sFlow and provides wire speed 10G/40G monitoring. The following article provides additional background: http://blog.sflow.com/2012/02/10-gigabit-ethernet.html Cheers, Peter On Tue, Jan 29, 2013 at 7:15 AM, Steven Fischer <sfischer1...@gmail.com> wrote: > although everyone here seems to hold Cisco in contempt, the Nexux 5548 is a > rock-solid switch - at least that has been my experience with it. > > > On Tue, Jan 29, 2013 at 6:27 AM, Piotr <piotr.1...@interia.pl> wrote: > >> >> Hello, >> >> I looking some 10G switches, it should work as TOR or core in DC.
