IBM WebSphere DataPower SOA Appliances is a family of purpose-built, easy-to-deploy network devices that simplify, help secure, and accelerate XML and Web Services deployments while extending SOA infrastructure. DataPower Appliances contain many specialized hardware components, including ASIC-based IPS, custom encrypted RAID drives, and (optional) hardware security modules. DataPower Appliances operate a single digitally signed firmware containing an operating system and application stack. DataPower's firmware runs on a flash storage device. IBM refreshes and enhances the DataPower firmware image every 10–20 weeks. DataPower firmware is a well performing and highly optimized platform to perform electronic messaging functions. As a result, users cannot run 3rd party applications on DataPower as they would a traditional server and operating system. Instead of a traditional file system, DataPower runs with a collection of isolated virtual file systems called 'Application Domains'. As a result, DataPower can appear to its client connections be any type of network file system with any type of folders and links.
