network and specialized hardware optimizers. Also included are: multitier, heterogeneous business services. Advanced virtualization management features, such as policydriven live virtual guest mobility and autonomic virtual guest placement, are planned future capabilities. The HMC serves as the access point for zManager functions, providing both a console user interface and a management API to facilitate integration with other IT process and service management tooling. The zManager’s RESTful published interfaces are available for use by external management products and installation-written programs. those related to availability, security and isolation, energy consumption, and multitenancy management. Such capabilities would represent another level of resource management intelligence that considers each optimization in context of its effects on others. For example, energy and performance management must be balanced against availability management and other goals to achieve each enterprise’s overall objectives.

hÁHardware availability monitoring hÁRecovery hÁAutomated problem management hÁField-guided hardware configuration, repair and verification tasks hÁDynamic on-demand capacity provisioning and business controls hÁEntitlement management hÁConfiguration backup and restore utilities zManager’s encapsulation and authoritative management offer a single point of control with a single administrative model. This is zManager’s fundamental design tenet, delivering the basis for management consistency and coherency in an ensemble. For example, it provides uniform virtual server lifecycle management controls for all hypervisors and hardware in an ensemble, including zEnterprise processors and zBX components such as racks, BladeCenter H chassis, power distribution units, top-of-rack switches and the POWER7 and System x blades. zEnterprise hypervisors are integrated and managed as system firmware. zManager automates hypervisor installation, deployment, configuration, recovery, optimization and service. Configuration data for virtual resources is maintained within the hypervisors. Configuration states of zEnterprise hypervisors and hosted virtual resources are maintained within zManager, failure-isolated from their hosting hardware components. zManager’s comprehensive virtual resource management and dynamic provisioning provide the overall lifecycle management needed to host

Workload Awareness A principle aim of zEnterprise is to align infrastructure resource management with business workload service goals. To meet that objective, the monitoring, reporting and optimization functions within zManager were engineered to be workload aware. This awareness contributes to a “resource management intelligence” resulting in superior resource optimization and alignment with the service level objectives associated with the hosted business workloads. Workload definitions are used to monitor and report performance levels against policy objectives and to adjust resource allocations to bring workloads into compliance with those objectives. For example, CPU capacity might be adjusted using either OS dispatching priorities or CPU-sharing controls implemented in hypervisors. Optimizations can likewise be applied to memory, storage, network I/O prioritization and network bandwidth allocations based on an overall view of ensemble workloads. Possible future resource management optimizations include

Next Generation From this overview of the major components of the zEnterprise system, we can clearly see that the z196 and z114 processor complex represents the next generation of the System z product offering. This new platform is complemented by the zBX, a modular system structure capable of hosting native POWER7 and System x processing blades. In addition, the zManager provides integrated and advanced hardware and virtualization management capabilities. Together, these components form the foundation of an integrated hybrid system architecture that can host multitier, heterogeneous business workloads, reducing operational complexity and providing workload-aware optimization of the IT infrastructure.

Jeff Frey, an IBM Fellow, is the CTO for System z. John Eells is a senior software engineer in the IBM Systems and Technology Group.
