Cisco Works LMS 2.5 on two servers, good or bad, how to?

[sin]

Hello

I'm installing LMS 2.5 for a costumer next week. The costumer want to install it using two servers for better performance.

Any one done this? Is it a good idear.

Any tips or source of information about it. Most Cisco dokumentation seems to imply a single server setup.

The Common Services 3.0 White Paper does explain Single Sign-on in Chapter 3:

The LMS 2.5 Deployment Guide is also a must read:

Hi,

you should also read the 'Large Scale Deployment' guide. Here it is. But unfortunately I don't have expirience as well.

In theory I would recommend the foll. config:

1st server(master for sync. DCR):

- CS

- CM

- DFM (receiving traps)

2nd Server(slave for sync. DCR):

- CS

- RME (receiving syslogs)

- IPM

Cheers,

Michael

Thanks Michael

This got me going. Just one more question.

Someone sugested this dual server solution to our costumer with two single CPU servers with 2GB ram.

I can se that Cisco recomend a dual CPU server with 4GB ram.

Now my concern is that this dual server with low performance is a bad design. I have the feeling that one sigle server with more CPU power and memory would give better performance and more simple setup.

Any thoughts or expirince is much appreciated.

Hi Rasmus,

i have done the above mentioned setup for a costumer with the unrestricted licence.

Every server needs to match the minimum hardware requirements!!

Everything else will lead you to a failing setup of CW or a very poor performance!

The dual cpu and 4 GB RAM is the recommendation for the unrestricted licence!

For the restricted the single cpu and 2GB is working well. For the restricted better use more than 2 GB RAM.

In my test environment i am running a LMS 2.5.1 and it is consuming 2,5 GB RAM. With only a few network devices monitoring.

Hope that answers your question.

Best regards,

Frank

I've got two multi-server clusters implemented on Solaris:

#1 four sun 240's 8GB ram as primary

#2 two sun 240's 8GB ram as DR cluster

for a mix of about 3,000 devices.

my dev system prior to this for LMS 2.5 was a 4 processor NT system with 4GB ram.
