Flexible, nondisruptive upgrade capabilities and self-healing characteristics in IBM eServer systems are currently being addressed. The IBM eServer z900 and preceding S/390 ® servers have been delivering leading-edge self-configuring, self-optimizing, self-protecting, self-managing, and self-healing capabilities that provide a solid foundation for those efforts. Current processors, memory, and input/output (I/O) cards are produced with dense physical packaging at high volumes without requiring fine configuration granularity. The granularity is provided under the control of Licensed Internal Code (LIC), which enables hardware entities to fulfill specific requirements based on encrypted product data. Disabled hardware entities are "dormant" and are reserved for capacity upgrades or self-healing. Concurrent capacity upgrade functions enable dormant hardware entities to reflect the new configuration. In case of hardware failure, healthy dormant hardware can be enabled, without disruption, to replace failing hardware. This paper describes the high level of concurrent configuration-change flexibility provided in the IBM eServer z900 and the asset protection approach on which it is based.

The IBM zEnterprise A Unified Resource Manager support for the IBM zEnterprise BladeCenter A Extension (zBX) hardware management and operational controls was established as an extension of the z196 system. System z hardware control design principles of concurrency, security, and automatic configuration were mainstays for the extended and new support for the zBX hardware and controls. This paper describes the hardware integration approach and different aspects of management: change, problem, serviceability, configuration, operations, performance, and business. In addition, included in this paper are details of the zBX firmware, components within the zBX blades, and the automation interfaces used between the hardware management console, Support Element, and the zBX components.
