[c-nsp] Cisco 11506 vs. cisco 6500 CSM and SSL module

[Vikas Sharma]

Hi,
 I am planning to deploy the load balancer. Initially I have thought of
CIsco 11506. Then I got to know about 6500 switch also support the same
functionality with CSM and SSL module and give better performance compared
to 11506. I was wondering if Cisco is already providing the same feature in
a module form in 6500 switch, why it need to provide another product? Pls
send me comparison details as I need to deploy it in my network.
