Overview:

Riverbed Steelhead products accelerateapplication performance and data transfer over the wide area network (WAN),overcoming bandwidth and geographical limitations to improve productivity andenable global collaboration. With Riverbed, file transfers that once took hoursor minutes, now take minutes or seconds. Workers today need access toinformation wherever and whenever they work - whether at corporateheadquarters, a branch office on another continent or on-site with a customer.The demand for anywhere / anytime access to data puts tremendous strain on ITto deliver an increasing number of applications over the WAN. Riverbed'saward-winning WAN optimization solutions strategically enable IT to centralizeand reduce operational overhead and expense, while improving end-usersatisfaction. Riverbed's products have been proven in some of the mostdemanding and complex networks in the world, with thousands of customersdeploying Steelhead WAN optimization solutions.Benefits:

• Accelerate the broad range of applications businesses care about most, including file sharing (CIFS and NFS), Exchange (MAPI), Lotus Notes, web (HTTP- and HTTPS-based applications), database (MS SQL and Oracle), and disaster recovery (EMC SRDF and FCIP) applications, using a range of application protocol-specific features that are unique to Riverbed
• Enable the consolidation of file, email, and application servers from remote branches to reduce costs and complexity — without sacrificing performance
• Cut bandwidth usage, typically by 60- 95 percent, allowing you to defer expensive upgrades
• Offer real-time visibility into application and WAN performance, so you can use applications and resources more efficiently and effectively
• Optimize performance while maintaining security to help you meet audit, compliance regulations, and other security requirements
• Deploy in minutes without changes to applications, users, routers, or IT infrastructure
• Integrate easily and seamlessly into the most complex environments
• Scale to hundreds of sites with any-to-any connectivity; support tens of thousands of users on one device

WithRiverbed Virtual Steelhead appliances, WAN optimization now extends todeployments where physical hardware may not be conveniently suited. Militarydeployments typically use ruggedized custom hardware, on which running avirtual machine is more convenient. Space-limited scenarios, such as mobilenews vans or construction trailers may also require a form factor that is freefrom the physical limitations of hardware appliances.

TheVirtual Steelhead appliance can be managed by industry standard virtualizationtools such that it fits seamlessly into fully virtualized data centerenvironments, where interoperability with existing management infrastructure isa must have. While targeted specifically for the above mentioned scenarios,Virtual Steelhead appliances can also be deployed as a cluster in order toscale to data center environments.

The Riverbed Difference: Speed, Scalability, Simplicity

Speed
Riverbed Steelhead products address performance limitations using a multitieredoptimization approach. Unlike older generation technologies, such as wide areafile services (WAFS) or file caching, Steelhead products optimize traffic usinga patented application agnostic algorithm to achieve massive-scale datadeduplication. The Riverbed solution layers TCP and UDP optimization as well asapplication protocol optimization on top of its data reduction technique todeliver a multi-tiered optimization strategy that sets the technologicalhighbar for WAN optimization, and delivers unparalleled applicationacceleration over the WAN.

Scalability
Riverbed's universal data store provides greater scalability than per-peerstorage models and reduces WAN optimization storage requirements. By avoidingthe per-peer storage limitation, companies can easily scale to hundreds ofsites with any-to-any connectivity. Steelhead products also utilize a TCP-basedtransport, which avoids the pitfalls of running a proprietary transport on ashared network. The Steelhead product family supports up to 12 Gbps ofoptimized throughput and 1 million concurrent connections. The product familyis one of the most scalable in the industry. With the RiOS-aware RiverbedInterceptor product, connections are always re-directed to the correctSteelhead appliance in a cluster, to ensure maximum performance. The 7050 seriesof Steelhead appliances also ensure easy integration into disaster recoveryenvironments that require massive scalability and can deploy Steelhead products in a matter of minutes. Steelheaddeployments can be performed from a single console with virtually plug-andplayinstallations, and the Riverbed solution does not require any changes toclients and servers nor the use of specific routing protocols. Steelheadproducts have been proven in a broad range of network environments alongsideVoIP, video conferencing, and QoS, giving customers flexibility and seamlessintegration with the existing infrastructure.
