Module Specification
Cisco SRE Service Module (SM)
●
The Cisco SRE Service Module is supported on Cisco 2911, 2921, 2951, 3925, 3925E, 3945, and
3945E Integrated Services Routers, part of the Cisco ISR G2 portfolio.
●
You can deploy 1 to 4 service modules per chassis, depending on the model of Cisco Integrated
Services Routers Generation 2.
Cisco SRE Internal Services Module
(ISM)
●
The Cisco ISM is supported on Cisco 1941, 2901, 2911, 2921, 2951, 3925, and 3945 Integrated
Services Routers, part of the Cisco ISR G2 portfolio.
●
You can deploy 1 ISM per chassis.

High-Performance, High-Capacity Hardware
The Cisco SRE modules offer compute performance and storage capacity on par with typical branch-office servers
or appliances. The various Cisco SRE modules provide different processor, storage, and memory options for
applications with different performance requirements. The hardware specifications are provided in Table 6 (later in
this document). Following are the main features:
●
x86 64-bit single- or multicore processor options
●
Up to 1 terabyte of hard disk storage capacity
●
Redundant Array of Independent Disks (RAID) 1 on Cisco SRE 900 and SRE 910 Service Modules
●
Hot-swappable disk on Cisco SRE 900 and SRE 910 Service Modules
●
Field-replaceable disks on Cisco SRE 700, SRE 710, SRE 900, and SRE 910 Service Modules
●
Hardware-assisted virtualization and embedded cryptography chip
All of the Cisco SRE hardware is independent of the host router resources, helping ensure maximum concurrent
routing and application performance. The module is connected to the router through an internal Gigabit Ethernet
link. High-performance hardware allows CPU and disk-hungry applications to be hosted on the Cisco SRE
module. The embedded cryptography chip supports common standard cryptography algorithms and provides
additional acceleration for security applications.
