I've deployed a couple of 5020s with 2148ts because I need the 10Gb port
density (for low-latency communication between a lot of 10Gb servers and
for aggregation of 1Gb ports). I don't know enough of your client's
requirements to say whether this is the right choice for them, but one
potential deal-breaker is that the Nexus 5k is layer 2 only, so it may
be inappropriate for use in the 'core'.
In any event, I haven't spent a ton of time working on these devices,
but I, or members of my team, have run into a few 'issues':
* It's not IOS. Probably not a big deal, but there are some
potential training issues, some changes in the way you normally do
things, etc.
* No VTP support (yeah, I know, but I use it and like it)
* QoS support is limited (due to cut-through switching, I suppose).
No DSCP, no marking functionality, ...
* 2148t ports are 1Gb only (5k SFP ports as well?). No place to
plug in my cheap-o 100Mb management switches/devices.
In my opinion, if you don't need the 10Gb port density, you're probably
better off with what you're already using.

I have a client that Cisoc is recommending the Nexus line of switches
for their data center. They will be using IBM blade switches and I'm
guessing these would be the 'core'.
They are looking at (2) Nexus 5010's and (2) Nexus 2000's.....totaling
60K.
I'm wondering why this would be recommended, since the only added
feature of the Nexus line from Cisco.com's video is that they have
10GB ports.....and really nothing else.
I'm almost ready to recommend my favorites....3750G's for this scenario.
Anyone have real world experience wirking with these devices and can
share comments? good or bad, and why you went with them?
Thanks
Chris
