I will be doing the above, but insome cases it can run into a fairly large number. I should have phrased my question better, but after i have segregated by dept / app / sec, how many is too many in a single broadcast domain?
It's difficult to say because a lot depends on your server apps, the amount of broadcasts etc.
In our datacentre we do not go above /25's for server vlans but to be honest i wish we had gone for smaller vlans. Not because of broadcast issues etc. as they perform quite adequately but we are looking to migrate to new data centres and having to move /25 vlans at a time is going to be a pain.
Something else you might want to consider is whether you desire to span VLANs across multiple switch stacks. If your doing routing on the distribution 6500s, and with the speed of L3 on 6500s, you might keep VLANs unique to each stack.
Whether to have multiple VLANs per stack is also influenced by whether you intend to route within the stack.
