Compact, Versatile, High-Performance Router Blade
® Services-Ready Engine (SRE) modules are router blades for the Cisco Integrated Services Routers Generation 2 (ISR G2) that provide the capability to host Cisco, third-party, and custom applications. The modules have their own processors, storage, network interfaces, and memory that operate independently of the host router resources, helping ensure maximum concurrent routing and application performance. Moreover, the modules come in two compact form factors designed to reduce physical footprint, lower power consumption, and simplify hardware installation at the branch office. The Cisco SRE includes a software controller that enables you to install applications on the module remotely at any time. This solution can help your organization quickly deploy new branch-office applications on demand, reduce operating costs, and consolidate the branch-office infrastructure.
Cisco SRE offers the next-generation application hosting platform that combines networking, collaboration, compute and storage services, and centralized management into a cohesive system designed to simplify infrastructure, support evolving business needs, and reduce operating costs at the branch office. It integrates all elements necessary to optimize branch-office IT infrastructure for delivery of applications from the data center and deployment of branch-office applications on demand, and houses them under a single chassis - the Cisco ISR G2.
Figure 1 shows the Cisco SRE Internal Service Module (ISM) and the Cisco SRE Service Module (SM), and Table 1 summarizes features and benefits of the modules.

Consolidation at the Branch Office
Organizations today are turning to server centralization and consolidation of branch-office infrastructure in order to reduce cost and complexity of their IT systems. These initiatives, while delivering the sought-after benefits, often create a new set of challenges:
• Application performance: Business-critical applications hosted centrally must provide performance and user experience as if they were hosted locally.
• Application survivability: Applications and network services vital to business transactions at the branch office must function during a WAN outage.
• Infrastructure flexibility: Consolidated branch-office infrastructure must provide sufficient versatility and resources to accommodate on-demand deployment of new services.
• Centralized management: Management systems must include all infrastructure components, offer multi-branch-office automation capabilities, and work transparently over the WAN.
Cisco SRE has been designed to help your organization address these challenges. It provides hardware, infrastructure, and management components optimized for deployment and delivery of branch-office applications. Cisco SRE hosted network and collaboration services support the centralization of applications into the data center by optimizing WAN access and providing communication survivability. Cisco SRE hosted compute and storage services support hosting and on-demand deployment of business-critical applications that must reside in the branch office. The entire system is managed centrally with the CiscoWorks LAN Management Solution (CiscoWorks LMS).
Cisco SRE modules and software infrastructure enable remote deployment and on-demand hosting of Cisco, third-party, and custom applications. A services-ready deployment model decouples the Cisco SRE hardware from the application software, enabling you to provision applications on the module remotely at any time. These capabilities, the rich collection of branch-office services available in the Cisco IOS
® Software, and the extensive set of network connectivity interfaces and modules - all integrated and housed under a single chassis - make the Cisco ISR G2 an ideal all-in-one platform for optimizing branch-office IT infrastructure.
The Cisco ISR G2 with Cisco SRE modules is the only device on the market today that can consolidate the functions of an entire branch office into a single box, eliminating the need for servers and appliances in the branch office.

Small Physical and Carbon Footprint
The Cisco SRE comes in two convenient form factors (Table 3): the small-footprint Cisco SRE Internal Service Module, which is installed inside the router, and the high-performance Cisco SRE Service Module, which is installed in one of the external slots on the router. The two form-factor options differ in the way they are supported on the various router models, as shown in Table 4. The capability to be housed inside of the Cisco ISR G2 chassis creates a powerful single-box device for a variety of branch-office applications. This solution has the following features:
• Unlike branch-office servers and appliances, Cisco SRE modules do not take up any additional physical space.
• Integration into the Cisco ISR G2 eliminates the need for cables, switch ports, power cords, and network interface cards (NICs).
• The Cisco SRE modules are highly energy-efficient, consuming only a fraction of the power required by branch-office servers and appliances.
• Remote power-on/power-off capability reduces power consumption when the module is not provisioned with any application; it can be scheduled for off hours.
The compactness of the combined Cisco ISR G2 and Cisco SRE solution translates into cost savings on power, cooling, cabling, and rack space, in turn leading to lower carbon emissions and natural resource waste.

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.
On-Demand Application Provisioning
You can easily install, replace, or uninstall applications from the Cisco SRE hosting infrastructure using familiar Cisco device and network management tools. The management tools allow you to replace one type of application with a different, even unrelated type of application on one or a group of Cisco SREs. Moreover, you can deploy the Cisco SRE in the branch office without any application when the network is being installed and quickly provision it with a supported application at a later time. Finally, you can use the same, consistent hardware footprint to host different applications in different branch offices. Figure 2 shows the various Cisco SRE provisioning options:
• Install a branch-office application on the Cisco SRE module at network deployment time.
• Install a branch-office application on the Cisco SRE at a later time.
• Replace one branch-office application with another application without any hardware changes.
• Use the same infrastructure to run various applications in different branch offices.
The on-demand provisioning capabilities of the Cisco SRE modules provide the following business benefits:
• Lower total cost of ownership (TCO): Cisco SRE modules eliminate the future cost of field deployment. You can provision new applications remotely through the CiscoWorks LMS or Cisco Configuration Professional application without any hardware or wiring modifications in the branch office.
• Improved infrastructure flexibility: Cisco SRE modules shorten the time to market for deploying new applications. You can address new business opportunities quickly by provisioning applications in branch offices that have been preconfigured with the Cisco SRE module.
• Infrastructure future-proofing: Cisco SRE modules provide flexibility to meet changing business requirements. The Cisco SRE modules can replace an application with a different, more relevant one.

Centralized Management and Troubleshooting
You can provision and manage applications hosted on the Cisco SRE with Cisco Configuration Professional, the command-line interface (CLI), and CiscoWorks LMS. These familiar network management (Table 5) tools offer both single- and multidevice management options. In addition, the Cisco SRE modules come with an onboard hardware diagnostic tool for monitoring the health of the hardware or troubleshooting problems. Centralized management for Cisco SRE modules provides the following features:
• Automated discovery reports the type, capacity, and properties of deployed modules and applications.
• Centralized monitoring reports the health and status of deployed modules.
• Centralized provisioning enables remote installation, upgrade, and uninstallation of applications.
Network management applications are instrumental in lowering operating expenses (OpEx) while improving network availability by simplifying and automating many of the day-to-day tasks associated with managing a branch-office network.
CiscoWorks LMS is a suite of integrated applications for simplifying day-to-day management of a Cisco end-to-end network, lowering OpEx while increasing network availability. CiscoWorks LMS offers network managers an easy-to-use web-based interface for configuring, administering, monitoring, and troubleshooting the network, saving time in configuring new services and reducing the time required to quickly isolate and fix network problems.
This GUI-based device-management tool for Cisco access routers simplifies configuration of routing, firewall, intrusion prevention system (IPS), VPN, unified communications, and WAN and LAN with easy-to-use wizards.
Cisco Configuration Professional is a valuable productivity-enhancing tool for network administrators and channel partners for deploying routers with increased confidence and ease. It offers a one-click router lockdown and an innovative voice and security auditing capability to check and recommend changes to router configuration. The application also monitors router status and troubleshoots WAN and VPN connectivity problems.

Cisco SRE hardware service and support is covered by the Cisco SMARTnet
® contract for the router in which the module will reside. Cisco SRE application software has an associated Cisco Software Application Support plus Upgrades (SASU) option, which you must purchase separately. In other words, Cisco SRE application support is not included in the router or router bundle Cisco SMARTnet contract. A single SASU contract attaches to a single Cisco SRE module, and any Cisco application running on that module is covered. There are three different SASU contracts, each corresponding to one of the three Cisco SRE modules (Cisco SRE 300 ISM, Cisco SRE 700 and SRE 710 SMs, and Cisco SRE 900 and SRE 910 SMs), as shown in Table 9.
