hi folks
if we install two CSM's in the same 6500, can we load balance serverfarmA using CSM1 & serverfarmB using CSM2.
would the csm's be in csm mode or rp mode? would we need to configure them identically or use hsrp for failover?
any ideas appreciated since i have 0 experience with content stuff.
thanks,

there is no more rp mode. Everything must be csm mode nowadays.
If you put 2 CSM in the same chassis, they can workd independently and therefore be both acitve, or you can have the same config on both and work in active/standby.
With version 4.2.x and the corresponding ios version, there is a command to sync the config between active and standby so you don't have to configure everything twice. The command is 'hw-module ContentSwitching X standby config-sync'.
Regarding the serverfarm the question is not really important. You first have to decide if you want to be active/standby or active/active.
Be aware that if you go for active/active you have no backup [you can't be active and standby at the same time] and you will have to split your traffic between the 2 CSM by configuring different vservers on each.
