IBM WebSphere DataPower SOA Appliances is a family of pre-built, pre-configuredrack-mountable network devices (XML appliances) designed to accelerateXML andWeb Services deployments while extendingSOA infrastructure. Originally these devices were created by DataPower Technology Inc., which was acquired byIBM in October 2005.[1]
ThisWebSphere family consists of hardware andvirtual appliances. The appliances are designed to be scalable, with options for high availability and clustering for increased performance and reliability.
This hardware model is a 1U rack mountable appliance that has fourGigabit Ethernet connections.[2]
This model is a 1U rack mountable appliance that has four Gigabit Ethernet connections and two10 Gigabit Ethernet connections.[3]
This model is a 2U rack mountable appliance that has 8 Gigabit Ethernet connections and 2 10 Gigabit Ethernet connections.[4]

DataPower Appliances contain many hardware components, includingASIC-based IPS, customencryptedRAID drives, and (optional)Hardware Security Modules.
DataPower Appliances operate a single digitally signedfirmware containing aLinux-based operating system and application stack. Its firmware runs on aflash storage device. IBM updates the firmware image every 10–20 weeks. Users cannot run third-party applications on DataPower as they would need a traditional server andoperating system. Instead of a traditionalfilesystem, it runs with a collection of isolatedvirtual file systems called 'Application Domains'. As a result, it can appear to its client connections to be any type ofnetwork file system with any type offolders and links.
DataPower firmware is mostly used to perform electronic messaging functions, like transformation and routing of messages as an enterprise service bus or to protect web services interfaces and the architecture behind them. It helps to integrate any two applications by considering them as services, and is platform and language independent.[citation needed]
