Riverbed to Showcase IT Infrastructure Performance Solutions at VMworld 2009

Virtualized Platform Allows Enterprises to Consolidate Branch Office IT Infrastructure without Compromising Performance

Riverbed Technology (Nasdaq: RVBD), the IT infrastructure performance company for networks, applications and storage, today announced its participation at VMworld 2009, taking place Aug. 31 – Sept. 3 at the Moscone Center in San Francisco. Now in its sixth year, VMworld is the leading virtualization event for IT professionals to discover how virtualization is revolutionizing the next generation of computing - providing even more efficiency and flexibility at a time when both are critical to the future of IT. At the conference, Riverbed® (booth #1332) will showcase the capabilities of its WAN optimization solutions, including the Riverbed Services Platform (RSP), a virtualized partition within the Riverbed Steelhead® appliance that allows organizations to consolidate their branch office IT infrastructure without impacting employee productivity.

Riverbed Steelhead appliances accelerate the performance of applications between data centers, remote offices and mobile workers by five to 50 times and in some cases up to 100 times. Steelhead appliances enable enterprises to efficiently collaborate across VMware environments, while at the same time centralizing and consolidating IT resources – all without sacrificing application performance. Joint Riverbed and VMware customers can more efficiently replicate VMware environments to set up remote and branch offices backed by disaster recovery, all while experiencing performance improvements of up to 55x.

With the RSP – the Steelhead appliances running on the VMware platform - enterprises can further consolidate IT infrastructure by running up to five remote office virtual edge services, without the need for separate dedicated servers. This approach allows enterprises to improve asset utilization, operational efficiency and business agility, while ensuring end-user satisfaction. Services currently available for deployment on the RSP include streaming media, print services, network management sensors, unified threat management/web proxy services and DNS/DHCP/IPAM.

To learn more about Riverbed WAN optimization solutions, conference-goers can visit Riverbed on the VMware 2009 show floor.
