SurePrep Deploys Silver Peak to Optimize Virtual Desktops across Long-Distance WAN

Virtual WAN Optimization Saves Tax Preparation Service Provider Time, Money, and Rack Space

SANTA CLARA, Calif., August 15, 2011 –During “tax season,” U.S.-based tax preparation service provider SurePrep puts increased stress on their wide area network (WAN) with innovative services that streamline tax and accounting practices. This increased volume of data, coupled with network challenges inherent to any global WAN, plagued the performance of SurePrep’s virtual desktop infrastructure (VDI), which spans multiple secure SAS-70 audited data center providers, a 200-seat service center in Irvine, Calif., a data center in Seattle, and a service center halfway around the world in Mumbai, India.

The combination of high-latency and poor network quality on international links made it “virtually” impossible for remote users to effectively use VDI during periods of peak congestion. This led SurePrep to deploy a WAN optimization solution. However, space limitations in the data center and logistical challenges associated with shipping equipment around the world eliminated options for hardware-based WAN optimization. Also, specific challenges associated with VDI such as packet loss, high flow counts, and non-TCP protocol traffic meant SurePrep needed a high-capacity and agile WAN optimization solution.

The answer was virtual WAN optimization from Silver Peak Systems, the leader in data center class WAN optimization. Silver Peak’s Virtual Acceleration Open Architecture (VXOA) allowed SurePrep to deploy virtual WAN optimization appliances on existing VMware ESX servers already deployed in the data center.

“There’s always an issue with access speeds when the server is not at the employee’s feet,” said Will Hosek, vice president of information technology for SurePrep. “Due to space limitations, international deployment issues, and other data center requirements, using a virtual appliance for WAN optimization makes a lot of sense. Silver Peak makes deploying and implementing WAN optimization very straightforward, and the virtual appliances provide agility that allows me to move WAN optimization on the platform of my choice, at any location.”

Not only did Silver Peak’s virtual appliances provide the versatility of being able to expand and contract their environment as needed, but also it provided them with the ability to get up and running globally within less than 24 hours once the localized network resources were configured.

“Due to its ease of implementation and versatility, virtual will now always be an option for us,” added Hosek.

Silver Peak VXOA powers the entire family of Silver Peak WAN optimization appliances. With Silver Peak VXOA, customers like SurePrep can deploy high-capacity data center class virtual WAN optimization on a wide variety of industry standard hardware platforms and hypervisors.
