Silver Peak launches virtual WAN optimization appliance for data center

Silver Peak upgrades its WAN acceleration software, adds virtual appliance for data center and Microsoft Hyper-V support, boosts data deduplication performance.

In its first major release in a year, Silver Peak Systems this week unveiled a data center-class virtual appliance for WAN acceleration and strengthened its data deduplication capabilities to further reduce the amount of traffic sent over the network.

Silver Peak's VRX-8 WAN optimization appliance is the major addition to version 4.0 of the vendor's operating system. Typically, most data center appliances are deployed locally from within a building or a campus-like setting but Silver Peak's VRX-8 WAN optimization is geared toward data center build-outs. The VRX-8 software uses the same network optimization technology as Silver Peak's NX and VX virtual appliances.

The VRX-8 runs as a virtual machine on VMware ESX hypervisors, delivers up to 1 Gbps of end-to-end (LAN and WAN capacity) throughput and supports SAN and NAS replication applications for disaster recovery.

Silver Peak bills the VRX-8 as the first virtual WAN accelerator for data centers, although Riverbed Technologies says its Virtual Steelhead product can work in data centers or remote sites.

"We work to solve data center to data center network issues," said Larry Cormier, senior vice president of worldwide marketing at Silver Peak Systems. "But we also support branch office to data center communications."

Silver Peak also claims is Network Memory embedded byte-level deduplication application reduces data by 50% more than the previous version of the operating system.

The 4.0 version ships with templates for storage replication but the dashboard can be customized for other application such as EMC Corp. SRDF and RecoverPoint, Hitachi Data System Hitachi Universal Replicator, Oracle and NetApp SnapMirror.

"Silver Peak launched its e VX-1000, VX-2000, VX-3000 and VX-5000 virtual appliances earlier this year with support for VMware's ESX hypervisors, and the 4.0 release supports Microsoft's Hyper-V virtualization for the VX-1000 branch office virtual appliance.

Mahmoud Harb, site operations Manager for Career Builder, said the job site company deployed a Silver Peak physical appliance on a primary site in the United States and two virtual appliances in sites in other countries. Harb said 90% of his company's data comes from uptime application such as HTTP, Microsoft SQL Server and SNMP traffic and is dependent on inline deduplication.

Harb said Career Builder picked Silver Peak after testing WAN accelerators from Cisco, Citrix, Fatpipe Networks, F5 Networks and Riverbed Technologies.

"All the demos would fail and the process would not work," Harb said. "Silver Peak uses a regular Internet connection, and you don't need a PhD to make it run. We like the virtual appliance. You copy the software and you are set to go."

Silver Peak 4.0 will be a free upgrade for existing customers, and will ship with all NX, VX and VRX appliances beginning in December. List price for a VRX-8 virtual appliance for data center replication is $69,995.
