My company is planning to move into a new building. We will be consolidating different buildings into this one location. Initially we will have 4 floors with 600 users, in the future we will assume 5 more floors and will have 2000 users.
We currently have a collocation that houses all of our critical applications. We have about 50 servers in this facility and our internet connections run through this facility. This collocation will be replaced with the new building. Judging by network traffic graphs we are no where near 1Gbps of aggregate traffic.
I'm considering purchasing either dual 4506 w/ SUP-IV or dual 6506E w/ SUP-32 for this building. I'll be running OSPF, NBAR, Netflow on the cores. I have a pair of 2821s running BGP and two ASAs.
Is the 6506e overkill for this building?
If i went with a 4506 which supervisor should i go with IV or V?
Which series switch do you guys suggest?
Thanks in advance!
