A CDE Definition
IBM's high-end mainframe architecture, which provides a control hub for the datacenter. zEnterprise enables IBM mainframes to incorporate IBM Power Systems running the AIX operating system and System x (x86) servers running Linux or Windows into a single integrated management system. The Power Systems and System x blade servers are installed in the zEnterprise BladeCenter Extension (zBX) unit, which provides a high-speed network connection to the mainframe.
The z114 and z196
Introduced in 2010, the first zEnterprise mainframe was the z196. Available in air-cooled or water-cooled models, the z196 supports up to 3TB of RAM and 80 user-configurable processor cores running at 5.2 GHz.
