We have a single catalyst 4500 in our datacenter. It's a WS-C4507R+E with an ipbase license. It has
2x48 10/100/1000BaseT Premium POE blades,
2x4 Supervisor 10GE (SFP+), 1000BaseX (SFP) blades in active & standby hot,
1x12 1000BaseX (SFP) blade and
1x12 10GE (SFP+) blade.
In the interest of replacing this EOL switch, I am looking for a replacement which will last 10-15 years which can easily handle this environment with the possibility of growth and scalability to accommodate modern servers coming with 10GE NICs. I'm also interested in having it in HA mode.
We also have 2960S in stacked an unstacked modes connected to this 4500 via fiber. What can be a good replacement for them also?
