IDSM 2 deployment advice

Hi everyone,

Currently we are trying to deploy two core switches 6509
with VSS (Virtual Switching System) and we have only two IDSM2

My concern what is the best solution to deploy the IDSM2 (WS-SVC-IDSM
2)

1- Having two IDSMs on one CORE switch 6509 while the other
CORE switch doesnt have any IDSM2 (one will be dedicated for the internet
traffic inline mode and the other for LAN traffic promiscuous mode )

=====>
we loss the concept of the redundancy and increase the throughput and incase
of failure we will be under risk

2- Having one ISDM2 on one core switch with two virtual sensors one
works as inline mode for internet traffic and the other sensor will work as
promiscuous for LAN traffic and the other IDSM2 will be on the second switch
for setting idle for redundancy and failover

=====>
we increase the redundancy concept but we degrade the throughput

For me I will with option 2 ===>what do you say????

A side from that we have 10 Mb internet link
