I am not clear and would like to help from everyone to easily explain.
Cisco ISR G2 2911 have Cisco SRE Service Module ( SM) and Internal Services Module ( ISM). Cisco 2911 support 2 Module.
When I Get a BOM of 2911 found SM-HDD-SATA-500 GB ( 500 GB hard disk drive for SRE 710 and 910).
My question is:
1. ISM is Built in 2911 ?
2. What is Purpose of ISM ?. what is Client benefit ? without this card what will be problem ?
( 500 GB hard disk drive so how client benefit from this disk. The hardware specifications has different in ISM so what is utilization by the card.
its directly operation speed in router)
3. 2911 have another option SM module. if any client want to buy the card then what he get benefit. cisco data sheet mentioned support applications for the SRE (SM) but i am not clear simply how the application support the router.
