Replacing our HP Core Switch
We have an aging 5308xl core switch with only 8GbE ports and 4 SFP sockets (plus 120 10/100 ports), which is severely limiting our options for connectivity to other switches.
The XL modules for it are quite expensive in comparison to newer models, so I'm looking at replacing the whole thing, and may be able to claw back some money by selling the old one on.
I've had a look costings for what we could replace it with, and the cost effective options that I've seen come down to a choice between:
What I could really do with, is someone to explain what the difference is between the models, especially between 4xxx and 5xxx models, and whether any of it is important to us. I'm open to suggestions, budget is undecided but around £5-6k to provide around 70GbE and 6 SFP ports.
Lastly, I ought to mention our core switch is used for routing, in case that makes any odds.
