CSS-CSM-ACE differences

Hello,

Does someone has a document that lists all the differences between the CSS, CSM and ACE. I don't really care about performances but more about features such as for example:

RHI: not available on CSS

Backup serverfarm: not available on CSS

Virtual load-balancer: only available on ACE

...

Thanks

Re: CSS-CSM-ACE differences

CSSes are an ordered list of route Partitions and they determine which partitions calling devices must search when they attempt to complete a call. In order to reach a certain destination, the called party's Partition must belong to the calling party's CSS.

When you attempt to make a call, Cisco CallManager looks into the CSS of the calling party and checks if the called party belongs to a Partition within the CSS. If it does, the call is placed or the translation pattern is executed. If not, the call is rejected or the translation pattern is ignored.

Try:

Re: CSS-CSM-ACE differences

you are a little bit off topic here.

The CSS is a Content Switch used for loadbalancing like the CSM and the ACE module.

There is no comparison chart that I know of.
