The KEMP LoadMaster R320, based on the high performance variant of Dell PowerEdge™ R320 server and leveraging the global support network of Dell, enables medium-to-large enterprises to assure the high availability and reliability of web-based business-critical applications.

The LoadMaster R320 enables data center clusters powering Internet sites and large intranets to intelligently and efficiently distribute network traffic among web and application servers. A resource optimization layer in front of applications and infrastructure servers gives IT administrators greater control to adapt to network changes and enable the best network and infrastructure performance.

The LoadMaster R320 delivers on these requirements through the inclusion of the latest advancements in Layer 4 and 7 load balancing, content switching, SSL acceleration, Layer 7 content switching, caching, compression, IPS, IP and Layer 7 persistence.
