Silver Peak today introduced free, downloadable low-end WAN acceleration software that can turn two x86 servers into data replication devices.

The company also announced an updated version of its flagship high-end virtual WAN acceleration software.

Silver Peak's free WAN software, dubbed VX-Xpress, is based on the Virtual Acceleration Open Architecture (VXOA) platform the company announced last month.

The VXOA software also powers Silver Peak's NX, VX, and flagship VRX WAN acceleration products.

VX-Xpress is an entry-level product aimed at organizations just starting WAN optimization, or at small branch or remote offices of larger companies.

The product leverages the same WAN optimization techniques as Silver Peak's higher-end products by using protocol acceleration, and adjusting TCP window sizes and selective TCP acknowledgements to reduce network "chattiness."

Silver Peak VX-Xpress supports 4 Mbps of WAN bandwidth with 8,000 simultaneous sessions.

A VX-Xpress-based appliance can be used to optimize backup and recovery applications such as asynchronous backup/replication tools from several vendors, including EMC, Hitachi Data Systems, Dell, NetApp, Hewlett-Packard and IBM.

Such an appliance can also be used to optimize TCP applications, such as Microsoft Windows file sharing, Microsoft Exchange, Microsoft SharePoint, Lotus Notes/Domino, Siebel, SAP, and Oracle, or interactive applications, such as Virtual Desktop Infrastructures (VDI), Citrix XenApp, Sunray, and Remote Desktop Protocol (RDP), as well as non-TCP applications, like voice-over-IP (VoIP) and video streaming.

"We're limiting [VX-Xpress] to point-to-point, so only two virtual appliances can talk to each other. Also, it's not supported by our management system [software], which is built for large networks with multiple devices," said Larry Cormier, senior vice president of worldwide marketing at Silver Peak. "You don't even have to register to get the product."

Silver Peak hopes that offering a free WAN engine can help the company help to get its foot in the door of potential customers.

"We believe 50% of those who would use this product would typically never be a customers of ours," Cormier said. "But we do believe people who use the free product will want to move onto fully-[enabled], supported products."
