RE: Nexus in DC?

Ok.you didn't say anything about the n7k in your message.

The n7k 10gig card can be "non-blocking".even thought that isn't the correct
terminology.

Also, the v2 cards are coming out next year which will address the 10g card
oversub issue.

The EX series doesn't really compete with the Nexus line. It's more of a
competitor to the 6500s/ME6500s. When the new Cisco Sup comes out it will
match the 10gig per slot capabilities. The EX is more of just straight 10GE
enterprise or SP.

The Nexus 7k. Of the 32-port 10GE linecard, you can only use 8 specifically
marked ports if you want the full non-blocking 10GE due to the backplane
connection. End 2009 they will release a linecard with 230Gbps backplane
connection, so that should give a little better port-density vs.
performance. Also the Cat6500 is oversubscribed as it also has a 40Gbps
backplane connection and you can buy 8-port 10GE linecards and 48-port 1GE
ones.

So I really like the non-blocking idea of the Juniper EX8200, great selling
point :-)

Which Cisco product are you referring to that is oversubbed?

So yes cool stuff! Still needs some time to get mature in terms of hardware
and software.
Juniper actually has a better DC switch with their EX8200 (totally
non-blocking), much cheaper for the same amount of bandwidth (not port
density, but the Juniper is NOT oversubscribed).

We're doing Nexus as well.  In fact, we're likely ordering everything
tomorrow.  Keep in mind, there's a limit to 12 FEX's to a 5000 cluster, or
at least that's what they tell me.  They screwed up our first quote because
our SE didn't look into this...

We are also rolling out the NX 7010 and 5020 in the next couple of months
as
part of our datacenter network upgrade. I am planning to use vPCs from the
5020 to 7010 but as we are using 2 VDCs there will be vPC for each VDC
translating to 4 10g coming out of each 5020. I am sure we will have to get
a extra 32 port 10g card with 8 ports dedicated for line speed for these
cross connects. Not to mention you need 1 keep-alive and 1 cross-connect
for
each VDC.
It seems that the 7010 can do lot of service aggregation using the ACE,
WAAS
modules but we just want to consolidate our aggregation switches in to
single set of chasiss.
On top of that in a few months time, we have provide active-active
datacenter functionality with a set of NX 7010 at each datacenter so that
traffic can be load balanced.
And the training was a 4-day Firefly course...which was fairly basic in
terms of depth and breadth of material covered
Fun times.......

Hey guys,
Any of you already having practical experience with big Nexus roll-outs
in
Data Centers? Running into any "problems"?
For a customer we are planning to deploy 5020 end-of-row switches with
2148T
top-of-rack switches, aggregated in 7018s fully loaded with 32-port
10-Gbps
blades. Just to give you an idea, the complete data center would be
around
256 rows (30,000 ports)...
Cheers,
Marc
