IBM zEnterprise EC12 (zEC12)

The demand for smarter solutions that leverage large volumes of data is pushing enterprises to deliver higher service levels with 24x7 availability, security, and scale, especially as they invest in new service delivery models like cloud. The new IBM zEnterprise® EC12 has up to 50% more total system capacity, new innovations like IBM zAware, security hardened into its architecture, and continued support for a hybrid infrastructure, while maintaining core workload strategies of data serving and transaction processing.


New technologies for cloud, big data, analytics, mobile devices and social media are redefining the way that businesses will be operating on and IT must be transformed to support these technologies. The shift can offer the opportunity to assess and improve the business model and interaction with the customers, partners and employees. To capitalize on this opportunity, organizations must be able to tap into their data and energize applications without going over budget and all the while keeping everything protected and secure.

The IBM® zEnterprise® System delivers unique value and industry leading capabilities allowing you to maximize the business value of your unique information. Make informed and optimized decisions, exploit cloud delivery models to improve operational efficiency, reduce costs and complexity with Infrastructure as a Service, and use the built in IBM z Systems™ security at every level to improve customer trust and confidence and know your IT infrastructure is secure. The IBM zEnterprise EC12 (zEC12) and the IBM z BladeCenter® Extension offer a proven hybrid computing design that supports mainframe and the distributed technologies of IBM POWER7® and IBM System x® blades. IBM z Unified Resource Manager (zManager) can manage and integrate workloads on the multiple architectures with the simplicity of a single system.
