middleware and application software, running under AIX* on POWER7 systems, and Linux technology- and Windows* technology-based environments on System x, run on general-purpose blades. Each blade is deployed with its hypervisor, extended with zManager capabilities, ready to host multiple virtual machines. System x blades include a Linux kernel virtual machine. POWER7 blades include the PowerVM* hypervisor and virtual I/O server. All are incorporated in zEnterprise System firmware. Generalpurpose blades within the zBX, like storage and network I/O, are virtualized. Blade optimizers are specialpurpose computing elements dedicated FIGURE 1 to specific functions, zEnterprise System typically used as business workload x86 Power accelerators. These are typically packaged as secure IBM software appliances, hosted directly on blades to maximize performance. z/VM One example is the IBM DB2* PR/SM Analytics Analyzer, xHyp pHyp which functions as a Z CPU, Memory and IO coprocessor appliance to SE run complex, highAMM z Blade Extension performance relational database queries Private Data Network (IEDN) from a z/OS platform within a zEnterprise configuration.

The hybrid nature of the zEnterprise System provides the foundation for hosting today’s heterogeneous and multitiered business applications and services. Service oriented architecture (SOA) adoption is driving replacement of monolithic applications with modular components deployed on myriad platform architectures, flexibly aggregated to provide business services. The zEnterprise environment integrates these infrastructure tiers under a single coherent management context and administrative model to reduce the operational cost and complexity of diverse distributed system configurations.

Together, they can host guest virtual machine personalities, which include z/OS*, Linux*, IBM Transaction Processing Facility and z/VSE* operating systems. The optional zBX extends these capabilities to encompass POWER7 and System x blade processor components. Each can host two IBM BladeCenter* H chassis, and each chassis can hold 14 blades, up to 112 blades per zBX. A zBX includes fully redundant top-ofrack switches supporting two private
