ACS and LMS

Hi,

What all could be the expected issues if we have installed LMS and ACS on the same server.

Please advise.

Re: ACS and LMS

This is an untested configuration, so I cannot say for certain. I can say that both suites use a lot of TCP ports, and an issue of TCP port starvation (or network buffer space starvation) is possible.

On top of that, you face the inherit security risks of keeping the network access software on the same machine as your NMS software. What happens if there is a bug in LMS where someone can take control of the server? Instead of compromising just LMS, they can potentially compromise ACS as well. Additionally, what if an LMS upgrade requires a reboot? Your ACS will also go down.

For these reasons we strongly recommend you do not install LMS and ACS together.

Also performance issues and production.

If LMS is slowing down your server for watever reason or ressources it needs, it may impact ACS and vice versa.

If you need to reboot LMS server, you reboot also the ACS server and your production will be affected.

An Authentication server should not be mixed with a network management software machine for this reason.

As Joe said, we don't recommend this.
