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:

Cheers,
Peter
