Core Switch recommendation

[bijbalaktn]

Hello,

We have a customer with a requirement for their new facility.

There are 6 towers with 5 floors each.   We have around  180 users /floor.   In all the number of users wouldn't go beyond  5000 users

Customer will have IP phones, AP,  and data port requirement on each floor.   He will also have around 20 servers each with a requirement of 10G uplink in the hub room in one of the tower.  Customer wants 10 G uplinks from access to core. Customer wants a collapsed core

Please help me design this, what I have come up with is

2960X 48 port PoE for the  access ( VOIP and AP )

2960X 48 port for the access (data )

Nexus 3064  for the collapsed core. 

Only resource hungry application would be  a scanning app which scans documents and uploads it as image file.  

Please advise.

I would also look into a 6800/6800ia combination. That could greatly reduce the complexity of the network:

Thanks Karsten, it ends up being expensive since customer doesnt want to go for a daisy chain setup.   Any other suggestion ?

For your core switches, depending on the number uplinks you have, you could use a set of 4500x (32 10gig ports each). If you have more than 64 10gig uplinks than maybe a set of 6840. If you have more than 80 10G uplinks than you can use a set of 6807.

Exactly how much is the budget for this project?

I know another peer who deployed nexus line of products in the campus core just before cisco introduce 6800.they claim they didn't have any issues except few bugs they had to patch in.closest we have is Nexus 9396 in one of our DCs configured for L2/L3 functions and never had issues as well

having said that,for small deployments not so much of a problem but something little bigger and growing I would consider devices from the appropriate portfolio,something that proven to be worked in the campus core setup.

I assume you have worked out all the features required and identified in Nexus 3064.Also look into buffer sizes,important for campus core deployments.You'd also notice that the campus range use store & Forwarding switching architecture which is somewhat important when you get into intensive ACLs and QOS,L3 features(at least this point of time).

as for the access Layer,I would go with something that has two PSUs

Simply for 5k user base I'd try to convince the customer to go for a feature rich modular core switch,something that could be used in the future to support the growth as well,unless the customer is a not for profit organization or don't save any lives :-)
