The IBM DataPower XC10 appliance is a new appliance based on the DataPower 9004 line specifically designed and optimized to simplify deployment, increase performance, and harden security at the caching tier of enterprise app infrastructure.  It can enable business-critical apps to scale cost effectively with consistent performance.

The DataPower XC10 appliance is designed for simple installation and rapid use ("plug-and-play") with WebSphere Application Server V6.1 and V7.0, where it can deliver a distributed caching solution in support of common distributed caching scenarios such as HTTP Session Replication and web side-cache accessed via a network connection.   In the "box" is a large (160 GB), remote, partitioned, replicated, scalable data cache. This cache can be utilized instead of a back-end database to provide increased application scalability and performance.
