WXA 4000

DELL SonicWall WXA 4000
Product Overview : DELL SonicWALL WXA appliances improve WAN performance of data traversing through the VPN.

Summary:

In today’s distributed enterprise, applications such as Microsoft® SharePoint and Windows® File Sharing transmit an increasing number of files and data sets over Wide Area Networks (WANs), overburdening available WAN bandwidth. To make matters worse, such collaboration applications can inefficiently retransmit entire files (rather than just incremental changes) multiple times, unnecessarily increasing WAN traffic. IT often responds by expending budget on more bandwidth or enhanced services. Alternatively, WAN acceleration technology can resolve the problem by allowing more efficient utilisation of the existing network bandwidth.

The DELL SonicWALL® WAN Acceleration Appliance (WXA) 4000 reduces application latency and conserves bandwidth, significantly enhancing WAN application performance and improving the end user experience for small- to medium-sized organisations with remote and branch offices. Unlike standalone acceleration products, the SonicWALL WXA 4000 seamlessly integrates with SonicWALL E-Class Network Security Appliance (NSA), NSA and TZ Series Unified Threat Management (NGFW) Firewall solutions to offer the unique combined benefit of both prioritising and minimising application traffic between sites, resulting in optimal network performance.

Features:

Simplified deployment through complete provisioning and configuration by a SonicWALL firewall drastically reduces the complexity of deploying, routing and integrating multiple WXA appliances across the network.

Increased security using SonicWALL Reassembly-Free Deep Packet Inspection™ technology provides an additional layer of security by scanning all traffic and data for threats before sending it to the WAN acceleration appliance.

Protocol optimisation provides LAN-like application performance for users accessing resources over the WAN by decreasing the latency and chattiness presented by inefficient protocols or application communication.

Byte caching and file caching reduce bandwidth consumption by orders of magnitude, extending the life of existing WAN links and providing a better user experience.

Reduced total cost of ownership (TCO) arrives through increased efficiency and overall utilisation of existing WAN bandwidth, which in turn avoids costly and unnecessary WAN upgrades.

Data compression across the WAN increases performance and reduces latency.

Windows File Sharing (WFS) acceleration helps improve response times while decreasing the amount of data transferred when downloading or accessing files from a shared drive.

Visualisation delivers real-time insight into the performance gains obtained by introducing WAN acceleration into the network.
