Branch Office Today’s Challenges?
Sales Drivers
Consolidation of Branch IT Infrastructure
Pain Points
 Despite centralization
some applications must
remain at the branch
 Placing physical servers
at the branch increases
infrastructure complexity
 Complex infrastructure is
inflexible and requires onsite technical knowhow
 Lack of physical space for
IT equipment and wiring
Pain Points
Pain Points
 Reduce cost of installing
or replacing applications
 One-application-per-server
model increases Capex
 Protect investment with
flexible infrastructure
 Most physical servers are
underutilized
 Reduce need for and
frequency of on-site visits
to implement changes
 Replacement or upgrade of
servers requires costly onsite visit
 Pay for infrastructure as
needed, not upfront
 Servers have higher energy
consumption
Differentiation
 ISR G2 is a consolidation platform for services – the only device on the market that
combines routing, switching, security, voice, and applications into one box
 The only general purpose server for the branch office in the blade server form factor
 One technical support contract for network equipment, servers, and virtualization

Configure Network Interfaces of SM-SRE
Service Module
1
The service module communicates with the host router through two internal
Gigabit Ethernet (GE) interfaces:
One GE interface connects to the router Peripheral Component Interconnect
Express (PCIe) (refer to interface GE0 ) This interface is sm slot/0 and is configured
through the Cisco IOS Software CLI. After the interface is configured, the vSphere
client communicates with the VMware vSphere Hypervisor™ through this interface.

The other GE interface connects to the Multigigabit fabric (MGF)
(refer to interface GE1). This interface, sm slot/1, is also configured
through the Cisco IOS Software CLI.

The third GE interface is located on the external face plate of the
Cisco SRE Service Module (refer to interface GE2). This Gigabit
Ethernet interface is configured and managed by the VMware
vSphere Hypervisor™.
