zEnterprise Ensemble A zEnterprise Ensemble is a
collection of 1..8 zEnterprise Nodes managed as a single virtualized pool of server resources
A zEnterprise Node is a single zCEC with 0..4 racks with up to 1..2 blade centers per rack
A zEnterprise node can be a member of only a single ensemble
The ensemble is the management scope for the Unified Resource Manager
A primary / alternate pair of HMCs provide the management console for the ensemble
– The alternative HMC takes over in case the primary fails

zEnterprise Networking Network Simplification with the zEnterprise Network: Intra Ensemble Data Network
(IEDN) Single physical, ethernet network combines System z CPC using OSA and Blade Center
extention (zBx)
Provides the data network for communications in the ensemble
Physical network is virtualized through the System z and blade hypervisors
Physical and virtual networks are managed from a central point of management
Secure communications (between System z and zBx) Physical security
Server access to physical and virtual networks is controlledby the Unified Resource Manager
High Availability Redundant network hardware
Unique System z QoS Isolated / dedicated equipment
Special purpose dedicateddata network & OSA-Express(no encryption required)

Hardware Management
Integrated Hardware Management across all elements of the multi-platform environment
– Operational Controls
– Firmware Inventory, Update, and Service
– Hardware and Firmware Problem Detection, Reporting, and Call Home, Field Guided Repair and Verify
– Physical Hardware Configuration, Backup, and Restore
– Integrated Discovery and Resource Inventory

Network Virtualization Access to the IEDN is managed
through the Virtual Network Ensemble Management functions in the HMC.
– Management of Virtual Networks. • Virtual Servers must belong to a
Virtual Network to communicate on the IEDN
• Provides network isolation of virtual servers not on same virtual network

Storage Virtual Servers see Virtual Disks
Virtual Disks may be either– 1:1 mapped storage resources– or for z/VM a minidisk created from a storage group
Storage Resources are– ECKD volumes (z/VM only)– FCP Logical Units (z/VM and IBM Blade
hypervisors)
Manage Storage Access Lists– exists per hypervisor– defines accessible storage resources
• storage resources typically appear in different Storage Access Lists
Support Server and Storage Admin Roles:– Server Admin
• Identifies ensemble storage requiements• Assign storage resources to hypervisors
– Storage admin• Assigns storage to the ensemble• Configures SAN
z/OS Storage mgt approach unchanged

Hypervisor and Virtual Server Management
Hypervisor management
– Start, stop, and query/list hypervisors
– Update and repair an IBM Blade hypervisor
– Monitor hypervisors and their resource use via Monitors Dashboard
• CPU• Memory consumption
Virtual server life cycle management– Create / delete– Define CPU and memory– Attach to virtual networks– Attach to virtual disks– Attach virtual DVD images
Start / stop virtual servers– Support scheduled operations
Monitor virtual server resource usage through Monitors Dashboard
Move a virtual server definition to another hypervisor
11 © 2012 IBM Corporation
zEnterprise Performance Management Platform management component responsible for goal-oriented resource
monitoring, management, and reporting across the zEnterprise Ensemble– Core component responsible for definition and implementation of goal-oriented
management policy
– Workload monitoring and reporting based on management policy
– Common approach to monitoring / management of platform resources across zEnterprise
– Extend goal oriented approach of z/OS WLM to platform managed resources
– Orchestration of autonomic management of resources across virtual servers• Provide Intelligent Resource Director like function across the zEnterprise • Management function will evolve over time
– Pushes management directives to the SE, Hypervisors, and OS agents as required across the zEnterprise
Integration of HMC console support– Integrated UI for monitoring, display of workload topology relationships, status alerts,
etc
– Definition of Performance Management Goals and Policy Administration

Platform Workload Resource Group
A Workload Resource Group is a grouping mechanism and “management view” of virtual servers supporting a business function
Provides the context within which associated platform resources are presented, monitored, reported, and managed
Management policies are associated to Workload Resource Groups– Performance Policy
Workload Resource Group definitions can be provided by higher level system management functions or created at the HMC

Workload Based Monitoring and Reporting
Provide reporting capability that shows usage of platform resources in a Workload context within a zEnterprise Ensemble scope– Across virtual servers / partitions supporting the Workload
Workload goal vs actual reporting
Drill down from overall Workload “performance health” view to contributions of individual virtual server– CPU, memory, network resource usage
Graphical views– Topology, trending graphs, etc
Links to system activity displays to show hardware utilization views
Reporting is limited to platform level resources, not trying to replicate tools that report on intra-OS resources and performance
14 © 2012 IBM Corporation
Network Monitors Dashboard User Interface display that shows the following major views
– Virtual Networks across IEDN, allowing drilling down to resources that comprise the virtual network: virtual switches, virtual servers, virtual network interfaces
• These views show the performance between the virtual switch and the guest• Provide data “by” virtual network (i.e., by VLAN) and across all virtual networks
– Physical Interfaces to the IEDN
• Virtual Switch Uplink interfaces to the physical interfaces that connect to the IEDN• External TOR ports connected to a router
– Physical Switches - TORs and ESMs
From the metrics collected, show
– Performance statistics such as transfer rates over intervals
– Both cumulative and interval metrics
– Also includes raw metrics as collected
– Resource state/status where available
– Resource utilization relationships (e.g., Servers using an OSA)
Network Monitors Dashboard provides both current and historical displays
15 © 2012 IBM Corporation
Managing Resources across Virtual Servers
Manage processor resources across virtual servers to achieve workload goals– Detect that a virtual server is part of Workload not achieving goals– Determine that the virtual server performance can be improved with additional
resources– Project impact on all effected Workloads of moving resources to virtual server– If good trade-off based on policy, redistribute processor resources

Enabling External Management Tools• Provide API access to Unified Resource Manager function
• API allows programmatic access to the same underlying function as is accessed via the HMC UI
• Same resource types, instances and policy
• API functions corresponding to views and tasks in the UI• Listing resource instances• Creating, changing, deleting resource instances• Operational control of resource instances• Monitoring• Etc.
• Enables management of an ensemble from external (to HMC) tools
• Key scenarios: Discovery, Monitoring and Provisioning use cases
