[c-nsp] Catalyst vs. Nexus

[Darrin Machay]

Other than FCoE, the major difference is L3 switching. The 5010 is a
Layer2-only device and the 4900M can do routing. If you're trying to
shave off microseconds, the 5010 will beat the 4900M in switching
latency. On the other hand, the 4900M is modular and well suited for
mixed, low-density 1gig/10gig deployments.

Subject: [c-nsp] Catalyst vs. Nexus

Hello,

I am working on the first 10Gig deployment in a small data center.  Main
driver is a SQL database, so there will be a bunch of SQL servers
virtualized using VMware, running against a SAN over iSCSI.

I've done some research and it looks like I can build the network using
a Catalyst 4900M or a Nexus 5010, at about the same cost.  I am familiar
with the Catalyst family, but have no experience with the Nexus.  At
this point, the only major difference I see is that Nexus supports Fibre
Channel (which I don't need).  For being different product families, I
am having a hard time understanding what the major differences are.  Can
anyone enlighten me?  
If anyone has hands-on experience with both and willing to share, that
would be most appreciated.

Thanks,
Michael Malitsky
