Riverbed Steelhead 2050 Series
Accelerating Applications for the Global Workforce - Mid-Size Office

Overview:

Riverbed Steelhead products accelerate application performance and data transfer over the wide area network (WAN), overcoming bandwidth and geographical limitations to improve productivity and enable global collaboration. With Riverbed, file transfers that once took hours or minutes, now take minutes or seconds.

Workers today need access to information wherever and whenever they work – whether at corporate headquarters, a branch office on another continent or on-site with a customer. The demand for anywhere / anytime access to data puts tremendous strain on IT to deliver an increasing number of applications over the WAN.

Riverbed’s award-winning WAN optimization solutions strategically enable IT to centralize and reduce operational overhead and expense, while improving end-user satisfaction. Riverbed’s products have been proven in some of the most demanding and complex networks in the world, with thousands of customers deploying Steelhead WAN optimization solutions.

With Riverbed Virtual Steelhead appliances, WAN optimization now extends to deployments where physical hardware may not be conveniently suited. Military deployments typically use ruggedized custom hardware, on which running a virtual machine is more convenient. Space-limited scenarios, such as mobile news vans or construction trailers may also require a form factor that is free from the physical limitations of hardware appliances.

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

The Riverbed Difference: Speed, Scalability, Simplicity

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

Scalability
Riverbed's universal data store provides greater scalability than per-peer storage models and reduces WAN optimization storage requirements. By avoiding the per-peer storage limitation, companies can easily scale to hundreds of sites with any-to-any connectivity. Steelhead products also utilize a TCP-based transport, which avoids the pitfalls of running a proprietary transport on a shared network. The Steelhead product family supports up to 12 Gbps of optimized throughput and 1 million concurrent connections. The product family is one of the most scalable in the industry. With the RiOS-aware Riverbed Interceptor product, connections are always re-directed to the correct Steelhead appliance in a cluster, to ensure maximum performance. The 7050 series of Steelhead appliances also ensure easy integration into disaster recovery environments that require massive scalability and performance.

Simplicity
Companies can deploy Steelhead products in a matter of minutes. Steelhead deployments can be performed from a single console with virtually plug-andplay installations, and the Riverbed solution does not require any changes to clients and servers nor the use of specific routing protocols. Steelhead products have been proven in a broad range of network environments alongside VoIP, video conferencing, and QoS, giving customers flexibility and seamless integration with the existing infrastructure.

Benefits:

Steelhead appliancess accelerate the widest range of enterprise applications.

Technological Leadership to Enable Your Business:

Riverbed Steelhead products have been proven to dramatically accelerate application performance in some of the most demanding customer environments. Our customers range from the Fortune 50 and Global 1000, to companies with one office.

Riverbed's award-winning products have consistently proven themselves as the highest performing WAN optimization solutions, consistently earning recognition as the "Technology of the Year - WAN Accelerators" by InfoWorld for six years running, and have been positioned by Gartner in the leaders quadrant in the "Magic Quadrant for WAN Optimization Controllers" report.

IT Infrastructure Consolidation - The Performance Trade-Off

Many organizations are looking to consolidate their IT infrastructure as a way to simplify management, increase resource utilization, and reduce costs. Unfortunately, the consolidated IT model can often result in diminished application performance and a hit to user productivity that offsets any consolidation cost savings. Riverbed Steelhead products allow users to access consolidated IT resources without trading off performance.

Moving into the Cloud

Whether companies are consolidating their IT infrastructure to create a "private cloud" infrastructure or outsourcing their infrastructure to Infrastructure as a Service (IAAS) or Platform as a Service (PAAS) vendors that provide "public cloud" infrastructure, the limitations on bandwidth and latency still remain. End users are far away from the data and applications they are trying to access, which results in poor user response and inefficient data delivery. Deploying WAN optimization appliances is a great way to defeat both these problems, while saving money on costly bandwidth upgrades. In short, WAN optimization can be the driving force to enable consolidation to public or private cloud architectures.

The Stateless Branch Office

Companies are approaching consolidation and virtualization of IT in branch offices in two ways. First, moving servers and storage out of the branch and into data centers where it can be more efficiently aggregated and managed, and then delivering access back to end users across the WAN. Second, taking local branch office servers and virtualizing them to run directly on VMware on the Steelhead appliances that are already deployed in every site, for edge services like printing or security. With no more complex build outs or remote servers to buy, install and manage, branches get set up faster and leaner, administrative overhead decreases, and users are more productive.

Enhanced Data Protection - The New Paradigm

Headline stories about tapes falling off trucks and the potential leakage of sensitive data have become all too common for both the enterprise and the consumer. CxOs require assurance that sensitive data will remain private and are looking for ways to reduce their data loss risk. With Riverbed, organizations can perform WAN-based backups or data replication without struggling to finish jobs in a tight backup window. Most enterprise storage vendors' solutions, including EMC and HDS, are already supported and previously unacceptable performance on the WAN can be improved by over 30 times with enhanced support for protocols such as FCIP and SRDF/A.

With accelerated replication, customers can also take more frequent snapshots and dramatically improve their recovery time in the event of a failure. Riverbed has advanced features for high end data center to data center disaster recovery, including special enhancements for more optimized throughput, tunable compression, and clustering for high availability and scalability. Customers can "fill the pipe" for high bandwidth environments maximizing speed, or choose to adopt higher compression, deduplication, and QoS to limit the impact on bandwidth for other applications on a shared WAN.

Enabling the Mobile Workforce

IT has often struggled to support remote users who need access to corporate data and applications, and mobile users have come to expect sub-optimal performance when they work remotely. Steelhead Mobile software extends Riverbed's award-winning technology to any PC or laptop to deliver acceleration wherever users connect. With Steelhead Mobile, applications run faster and remote workers are no longer "remote." Desktop virtualization solutions can also be optimized for use on the WAN.

Riverbed Optimization System (RiOS):

RiOS software powers Steelhead products through a combination of patented data reduction, TCP and UDP optimization, and application- level protocol optimizations. Together, these technologies, along with RiOS management capabilities, provide a comprehensive solution for enterprise WAN optimization. RiOS consists of four key components:

Data streamlining – RiOS data streamlining works across all TCP and UDP applications to reduce bandwidth utilization, typically by 60-95 percent. Data streamlining works across file sharing, email, CAD, ERP, VDI, web-based HTTP and HTTPS applications, databases , and all other applications that use TCP and UDP.

Transport streamlining – RiOS transport streamlining reduces the number of TCP packets required to transfer data by 65-98 percent. Transport streamlining also enables the acceleration of SSL-encrypted traffic throughout the enterprise to eliminate the security and performance trade-off. With HS-TCP and MX-TCP, RiOS can enable greater utilization of high bandwidth links (i.e. long fat networks (LFN) such as OC3, OC12, metrofiber).

Application streamlining – RiOS application streamlining offers the broadest support of application-specific modules for key enterprise applications to provide additional application performance improvements on top of the data streamlining and transport streamlining optimizations performed on all TCP traffic. By reducing application protocol chattiness up to 98 percent and minimizing application overhead, RiOS can provide massive throughput increases to applications including file sharing (CIFS and NFS), Exchange (MAPI), Lotus Notes, Web (HTTP and HTTPS),database (MS-SQL and Oracle) and storage protocols like FCIP and SRDF/A (EMC).

Management streamlining – RiOS enables easy deployment through auto-discovery of peers and auto-interception of traffic, with no reconfiguration of clients, servers, or routers. Many customers deploy Steelhead products in minutes and RiOS simplifies ongoing management by providing simple, but powerful web-based and command-line interfaces, in-depth reporting and real-time NetFlow export. Simple integration into the network has led to Riverbed deployments in a vast array of network environments and topologies including, but not limited to, MPLS, VoIP, video conferencing, QoS, VPN, satellite infrastructure, ATM, frame relay, microwave, and wireless.
