I searched for some documents about SAM in cisco website and could not get any...

Hi,

The SAM is pretty much the same that a IOM module but without any physical ports, it would allow the CSS to handle more flows.

I do not really have a doc, but this information is very useful, notice is for 11503 (same for 11506 while you can add more modules to it):

CSS 11503 Performance Summary

1. Maximum number of Layer 4 connections/second:

Chassis Configuration

Maximum HTTP CPS

Switch Control Manager (SCM)

7,800

SCM & Session Accelerator Module(SAM)

12,200

SCM & 2 x SAM

19,300

2. Maximum number of Layer 5 connections/second:

Chassis Configuration

Maximum HTTP CPS

Switch Control Manager (SCM)

3,700

SCM & Session Accelerator Module(SAM)

5,900

SCM & 2 x SAM

9,400

Hope it helps!!

Just to clarify when I say that the SAM and IOM are pretty much the same I mean they both have an SP (Session Processor) that will add more resources to the CSS and will allow more connections to be handled as described before.

Hope if helps!!
