IBM WebSphere DataPower SOA Appliances is a family of pre-built, pre-configured rack-mountable network devices (XML appliances) that can help accelerate XML and Web Services deployments while extending SOA infrastructure. Originally these devices were created by DataPower Technology Inc., which was acquired by IBM in October 2005. This WebSphere family consists of rack-mountable network appliances, blade appliances, appliances that rack inside a z/OS mainframe, and virtual appliances.
