Silver Peak provides a robust WAN optimization solution that addresses the bandwidth, latency, and packet loss issues that are common to most enterprise environments. Silver Peak's optimization techniques are all performed in real-time and primarily at the network (IP) layer to ensure maximum performance across the widest range of applications and WAN environments.
Silver Peak appliances leverage the following Virtual Acceleration Open Architecture (VXOA) technology components to accelerate all enterprises applications in a secure and reliable fashion:
Network Memory: Silver Peak's patent-pending solution for disk based WAN deduplication. Network Memory inspects all traffic that is sent between clients and servers, storing information as a local instance in Silver Peak appliances. Repetitive information is delivered locally rather than sent across the WAN, improving application performance and WAN utilization. Cross-flow payload and header compression provide additional gains on first-time data transfers and non-repetitive traffic.
Network Integrity: Silver Peak employs a variety of real-time techniques to address packet delivery issues common to shared WAN technologies, such as MPLS and IP VPN. These include adaptive Forward Error Correction (FEC) and Packet Order Correction (POC) to overcome dropped and out-of-order packets, and advanced Quality of Service (QoS) techniques to prioritize traffic and guarantee network resources.
Network Acceleration: Silver Peak mitigates the impacts of latency across the WAN by using various TCP acceleration techniques, like adjustable window sizing and selective acknowledgements, as well as CIFS acceleration techniques, such as read-aheads and write-behinds. These tools help to overcome inherent chattiness that can otherwise hamper application performance across a WAN
Secure Content Architecture™: Silver Peak keeps enterprise data secure with its Secure Content Architecture. All NX appliances are equipped with hardware based AES encryption to protect local data stores. Optional IPsec keeps content safe when it traverses the WAN. Intelligent security policies can be established for granular control of WAN traffic.
Virtual Acceleration Open Architecture (VXOA)
Virtual Acceleration Open Architecture (VXOA) is Silver Peak’s award winning WAN optimization software. It is used on all Silver Peak NX, VX and VRX products, and includes the following real-time network optimization techniques:
- Silver Peak's patent-pending Network Memory™ technology to significantly reduce the amount of data traversing the WAN and ensure LAN-like application performance.
- Network Acceleration techniques to overcome WAN latency
- Network Integrity features to mitigate the effects of packet loss across the WAN, including robust Quality of Service (QoS) policies to ensure applications are prioritized appropriately and given adequate network resources.
Silver Peak’s award winning NX appliances are standalone devices that seamlessly fit into any enterprise network, sitting between network resources and the WAN infrastructure that is used to connect them to remote users. Deployment of NX appliances requires absolutely no client, server, or application reconfiguration.
VX appliances are software-only versions of NX appliances. They support all the same VXOA features as their NX counterparts, but in a virtualized manner. By deploying Silver Peak’s VX family of appliances on industry standard servers, enterprises reap all the cost and flexibility benefits of server virtualization.
The VX-Xpress is a free, fully functional entry level VX appliance. It is an easy and cost effective way for getting started with WAN optimization, or for deploymentof Silver Peak in small point-to-point networks.
Silver Peak’s VRX appliances are virtual WAN optimization devices designed specifically for data center deployment. They deliver the highest end-to-end throughput and simultaneous sessions of any virtual WAN optimization device and are proven compatible with all leading storage solutions and data center switching devices.
Global Management System
Global Management System (GMS) is a powerful platform for the deployment, management, and monitoring of a Silver Peak-enabled Wide Area Network (WAN). GMS gives IT managers detailed visibility into all aspects of application delivery across a distributed enterprise, including WAN performance statistics, application analysis, and tools for the configuration and management of Silver Peak NX Series appliances. With Silver Peak, enterprises can centrally deliver business critical applications in a secure, scalable, and cost effective manner.
