ACE Module versus Content Switching Module with SSL?

Unanswered Question

I've got a CSS 11506 and am supposed to be planning the refresh of this device in the future to something that will support IPv6 and do everything the CSS does.

I'd originally planned for the ACE module, but I now see there is a Content Switching Module with SSL available.

I can't tell any difference in what they do based on the limited data on the web.  Do either of them support IPv6 if used with a Sup720?  Will one of them have a longer life than the other?

The end-of-sale, end-of-support annoncement for the CSM-S will be released at the end of this month.

So I would not chose that option.

ACE is the new loadbalancer from Cisco and it does everything the CSM did plus more.

ACE will do IPv6 by the end of this calendar year normally.

No EOS/EOL for the CSS on the calendar yet.


Thanks.   Since the ACE is quite expensive, I'm going to recommend hanging on to the CSS for a while longer - we don't NEED IPv6 yet.

We'll update our Cat6500s to Sup720s (and go to Native mode) and if we need to present IPv6 addresses to the world for CSS VIPs we can do that bridging/translating in the Cat switch.

Then we'll have to put in a pair of ACE modules in the 6513 to replace the CSS11506 and still have fault tolerance... Yikes that will be expensive.

You could also go with the ACE4710.

That is correct - the price comes from the throuput license. The device also comes with the default 5 device context feature. If you don't need more than you don't need to buy additional virtualizatin license.

There are some bundle solution that might make the solution more attractive. I would suggest reaching out to you account team to discuss pricing.

I did a 4710 deployment two months back. It is MUCH easier than the CSS was.  The GUI is nice and clean and you can actual

ly pretty easily do 99% of the configuration tasks in the GUI.  This makes it easier to train people on maintaining it.

I am a fan of the 4710.
