I'm to write a business case for LMS 3.0 upgrade. I have read system requirement. but I hear also on real world different suggestion. I have almost 2800 Cisco devices switch and router. I have also close to 2500 Cisco access point. our end devices close to 50,000. base on this how many server do I need to run Ciscoworks efficiently. power full server vs multiple server jut meet the minimum requirement.
If you choose to manage standalone APs in LMS, they count against the total device count. If you only add the WLSE to LMS, then you can only get wireless end hosts via the WLSE (but LMS will not track inventory, topology, etc.). The upside of this, of course, is that you are not eating up available devices with APs. And yes, the WLSE does provide a lot of services that LMS provides in addition to offering wireless-specific templates and services.
The upside of managing all APs in LMS is that you have one application in which you can do your inventory, software, config, topology, and user management.
Eliaspaulos, you might be interested to note that CiscoWorks LMS 3.1 is out now.
With 2,800 + 2,500 APs (5,300) and 50,000 MAC ports to manage you're going to need LMS 3.1 and the >5,000 device scalability. You'll end up putting Common Services and RME on one beefy server. The other components can go on another server, but even DFM and Campus manager have different scalability requirements.
This isn't an easy question that is answered on a forum like this. You should get with your sales SE to map out a solution. Or work with your Advanced Services contact.
