The business environment is changing

Increasing consolidation of IT Lower costs & easier to manage Guaranteed data protection

Increasing dependence on business applications

Increasing distribution of organizations 67% of employees work in a location other than the

headquarters Globalization – global clients, global projects, global

offices

Distributed offices present new IT challenges

Lost Profit

Userfrustration & mutiny Seconds of “wait time”

becomes minutes…hours…days.

Users create work-arounds to avoid corporate applications

Users can’t get the job done

Applications are just too slow

Small tasks become big ones

IT is focused on fire-fighting

The Riverbed Optimization System (RiOS)


12

Application protocol inefficiencies

Transport protocol chattiness

Not enough bandwidth

If you don’t solve all three, users won’t see performance benefits.

The three root causes of poor wide-area application performance

Data Streamlining

Transport Streamlining

Application Streamlining

Management Streamlining

• Eliminate redundant bytes from transfers

• Eliminate transport protocol inefficiencies

• Optimize application WAN performance

• Enable transparent deployment & central management

RiOS is an integrated approach

The RiOS underlying framework

Initiate new TCP sessions

1. Accelerate the applications that are most important to your business• Works for all application that use TCP• Orders of magnitude improvements

Maintain TCP sessions

Data streamlining overcomes bandwidth limitations

ReconstructedFiles & Data

RequestFiles & Data

• Steelhead auto-intercepts response, and segments data• Only new bytes compressed & sent over the WAN

60-99% reduction in WAN utilization

• Requests go directly from the client to the server


• 16-Byte references communicate megabytes of existing data• Remote Steelhead reconstructs data and delivers it to the client

Transport streamlining overcomes TCP limitations

Make TCP payload bigger

Simplicity is key for a successful WDS deployment

Simple to deploy

Immediate impact across applications

“I was very surprised by how simple the deployment was. I expected a complex integration, but it only required that I give each appliance an IP address. It was only a matter of minutes before I had the boxes up and running.”

- Senior Systems Engineer, Investor AB

“We were quite surprised when one day our backup process took 25% of its usual time, because we were busy analyzing the effects of Riverbed Steelhead appliances on our FTP transfers. We made no changes to our software – the Steelhead appliances just started working right away.”

- Director of IT, Mercury Interactive

More on transparent deployment

Proxy TCP

• No agents required on clients or servers

• No tunnels need to be configured

• Un-optimized traffic is automatically passed through



26

• 4-port 10/100/1000 Ethernet cards• TCP connection forwarding• Diverse in-path and out-of-path deployment options

• Serial clustering• Parallel clustering• Hot backups

• Fail-to-wire Ethernet cards• Dual power supply (optional)• RAID (optional)

eliminated more than 20 non-billable

hours annually for the average attorney

working in a remote office.

Now we can provide our high-quality

client experience while eliminating

behind-the-scenes manual labor by our

attorneys.

That also translates into an estimated

$980,000 in annual productivity gains

for Allen Matkins.”

- Frank Gillman, Director of IT


35

A customer study on Allied Capital Corporation

• Background▪ 4 Locations in the US▪ Access to data slow for distributed users▪ SEC Requirements demand data control &

compliance

• Key benefits from deploying Riverbed▪ 7 month payback period▪ Data consolidated – easier to find▪ Data sprawl gone – data is secure▪ More productive users worldwide

“Within a matter of 24 hours, we

were able to prove that we had

significantly accelerated performance

across the network.

For example, opening a 10 MB

excel file from DC to New York

was reduced from 2 minutes and

59 seconds to just 5 seconds.

Users even noticed performance

increases in email downloads and

CRM access.”
