Riverbed's Steelhead appliances provide the highest level of WAN performance across the broadest range of applications. Available in a wide range of sizes – all powered by the Riverbed Optimization System (RiOS) – Steelhead appliances are also the most scalable approach to application acceleration across your WAN.

Steelhead appliances come in a range of sizes to ensure that each of your offices has a properly sized acceleration appliance. Plus, with our upgradeable licensing capability, you don’t need to oversize a box for your remote offices and can ensure that you still have room to grow while protecting your WDS investment.

Our smallest Steelhead appliance 100 is meant for offices with just a few people; our 6000-series appliances carry enterprise-class data center workloads and can meet the needs of offices with many thousands of users.
