11.6 HMC in an ensemble
An ensemble is a platform systems management domain that consists of up to eight z13s or
IBM zEnterprise System nodes, and up to eight zBX Model 004 systems. Each node is a
zEnterprise CPC or a zBX Model 004. The ensemble provides an integrated way to manage
virtual server resources and the workloads that can be deployed on those resources. The
zEnterprise is a workload-optimized technology system that delivers a multiple platform,
integrated hardware system. This system spans z Systems, System p, and System x blade
server technologies.
Management of the ensemble is provided by the IBM zEnterprise Unified Resource Manager.
11.6.1 Unified Resource Manager
The ensemble is provisioned and managed through the Unified Resource Manager, which is
in the HMC. The Unified Resource Manager provides a large set of functions for system
management.
Consideration: The ensemble HMC mode is available only for managing IBM z Systems
servers (z13s, z13, zEC12, zBC12, z196, and z114).
