PowerVM and the AIX 6 operating system are enhanced to provide additional flexibility and manageability. AIX 6 Technology Level 4 enhancements include Live Application Mobility with SAN devices in workload partitions (WPARs). Live Application Mobility, the capability to relocate a WPAR from one AIX system to another with no application downtime, is enhanced to support WPARs that use SAN devices. This new capability provides businesses with additional flexibility to configure WPARs with traditional SAN storage devices while preserving the capability to relocate WPARs to provide additional application availability, workload management, and energy savings. Before this enhancement, Live Application Mobility was only supported with WPARs that used NFS filesystems. This capability requires AIX 6 Technology Level 4 and the Workload Partitions Manager V2.1.
PowerVM enhancements include:
- Improved server utilization and shared I/O resources to help reduce total cost of ownership and make better use of IT assets
- Improved business responsiveness and operational speed by dynamically re-allocating resources to applications as needed to better match changing business cycles or handle unexpected surge in demand
- Simplified IT infrastructure management by making workloads independent of hardware resources, thereby enabling clients to make business-driven policies to deliver resources based on time, cost, and service-level requirements
Management Edition for AIX has been enhanced to include improved reporting, easier installation and configuration, and new capabilities for capacity management. New metrics are available in the monitoring component to include statistics on multiple shared processor pools, active memory sharing, and integration with IBM Systems Director to provide integrated enterprise monitoring and management from one user interface.
AIX Enterprise Edition has been enhanced to include improved reporting, easier installation and configuration, new capabilities for capacity management, improved application discovery as well as the latest versions of AIX 6 and Workload Partitions Manager.

PowerVM delivers industrial-strength virtualization for AIX, IBM i, and Linux® environments on IBM POWER® processor-based systems. IBM Power Systems servers coupled with PowerVM technology are designed to help consolidate and simplify IT environments.
PowerVM enhancements for Power Systems include:
- N_Port ID Virtualization (NPIV): PowerVM V2.1 now supports N_Port ID Virtualization on IBM i and Power Systems blade servers. NPIV is a Fibre Channel industry standard technology that provides the capability to take a single physical Fibre Channel host bus adapter (HBA) port and divide it such that it appears, to both the host and to the SAN, as though there are multiple World Wide Port Names (WWPNs). NPIV allows physical N_Port to be logically partitioned into multiple logical ports/Fibre Channel addresses so that a physical HBA can support multiple initiators, each with a unique N_Port ID.
- IBM i
support: IBM i
is enhanced to support additional virtualization technology provided by PowerVM:
- For enhanced availability, IBM i 6.1.1 partitions can be configured in multipath configurations where one IBM i 6.1.1 partition uses two VIOS partitions to connect to the same IBM System Storage device. This support is provided on IBM POWER6 processor-based servers. It is not supported with IBM BladeCenter® solutions.
- IBM i 6.1.1 partitions support NPIV, providing enhanced support for attached IBM System Storage solutions. With POWER6 processor-based servers and blades, NPIV support is available for the following tape libraries: 3584 (TS3500) and 3573 (TS3100 and TS3200). With NPIV support, these Fibre Channel-attached tape libraries can now be attached to POWER6 processor-based blades running IBM i 6.1.1. For POWER6 processor-based servers, NPIV support is also available for the DS8000. NPIV support is provided via 8 Gb Fibre Channel Adapters.
- IBM i virtual tape support via PowerVM VIOS is expanded to include DAT72 and DAT160 internal SAS drives on POWER6 processor-based servers with IBM i 6.1.1 partitions.
- Live Partition Mobility enhancements:
- Hardware Management Console (HMC)/Integrated Virtualization Manager (IVM) support for maintaining existing and allowing user override for the virtual slot IDs for VSCSI adapters created within the VIOS on the destination server.
- Support for VIOS to maintain user-defined names for virtual target devices when created on the destination.
- Support for Mover Service Partition (MSP) to validate adequate network bandwidth between systems as part of the validation step.
- Changes to HMC to enhance profile handling, eliminate warning messages when a different profile is not chosen by the user, and make the selection of a new profile name an advanced user option.
- HMC/IVM support to enhance user interlock for migrations where VLAN or VSCSI configurations are detected as nonsymmetric on destination.
- Support for page hints to decrease the amount of data moved; support for PowerVM to process page hints from the operating system and not transfer pages; operating system support for marking pages that do not need to be moved.
- HMC/IVM interface to allow the user to specify the default IP address to use on MSP for migration.
- VIOS support for SCSI-3 reserves on LUNS of partitions being moved.
- VIOS support for allowing IPSEC to be configured so that mobile data can be encrypted.
- Fibre Channel over Ethernet: PowerVM now supports standards-based Fibre Channel over Convergence Enhanced Ethernet (FCoCEE).
- PowerVM Lx86: PowerVM Lx86 V1.3.2 adds support for the x86 SSE and SSE2 instruction sets, allowing a broader range of Linux/x86 applications to execute. PowerVM Lx86 V1.3.2 also supports additional Linux operating systems, including Red Hat Enterprise Linux 4.8 and 5.4, and Novell SUSE Linux Enterprise Server 10 SP3.
AIX 6 Technology Level 4 includes the following enhancements:
- Workload partitions rootvg support to simplify the management of WPAR environments and to provide the WPAR administrator increased autonomy from the global instance administrator; WPARs can now be configured with the WPAR rootvg on a SAN device.
- AIX Run Time Expert is a new capability of AIX that enables profile-based management of AIX performance, NFS, network, and other AIX configuration aspects. The AIX Run Time Expert is similar in concept to the AIX Security Expert (introduced with AIX 5.3 Technology Level 5) in that a configuration dialog is used to specify configuration parameters for many aspects of AIX instead of having to set these parameters in multiple separate SMIT panels or configuration files. Once the configuration is set, the configuration can be exported as an XML file that can be applied to other AIX systems to provide an identical configuration.
- Probevue support for Java, the AIX probevue dynamic tracing facility, is enhanced to support dynamic tracing of Java applications.
- Performance Aide is now integrated with topas and Performance Management
for Power Systems.
The topas agents included in AIX are enhanced to provide additional capability for
performance management tools other than AIX, including:
- Customers using the Performance Toolbox (5765-E74) will no longer have to install the Performance Aide agents on systems running AIX 6 Technology Level 4 or AIX 5.3 Technology Level 11 to gather information about AIX performance. The topas agent included with AIX will now include all the functionality formerly included in the Performance Aide (5765-E68) product. Customers using the Performance Toolbox with earlier releases of AIX will need to continue to use the Performance Aide Agent. Additional information about the Performance Toolbox can be found on links from the main AIX page
- The Performance Management for Power Systems (formerly known as PM for AIX)
application will be able to use the topas agent infrastructure to gather performance
information about AIX. The PM for Power Systems offering allows the customer
to upload performance information to IBM and then view the data in the form of
reports. The Performance Management Service collects the performance data
from the system and then sends the data to IBM via Electronic Service Agent (ESA)
IBM stores the data for the client and provides a series of reports and graphs that show the server's growth and performance. The topas agent now provides all the information needed by the PM for Power Systems offering, simplifying client deployment and use of PM for Power Systems. Additional information on PM for Power Systems can be found by links on the main AIX page
- Storage management enhancements. AIX storage management now includes support for Fibre Channel over Ethernet (FCoE) devices and new utilities to control data placement on Flash devices to improve the flexibility and performance of storage devices on AIX.
- Performance Management for Power Systems integrated data collector. AIX allows clients to collect performance data to use with the Performance Management for Power Systems tool to assist clients with capacity management and system planning. This new facility is an extension of the topas data collector function that is already included with AIX. If the client turns on this data collection, it will automatically collect nonproprietary utilization and growth data at a partition level. The collected data is automatically transmitted to and securely kept at IBM through the ESA. Clients can access summary-level utilization and growth-trend graphs through a secure Internet connection. Clients can elect to access more detailed information for a nominal charge. This information is also available to the client for use with the IBM Systems Workload Estimator for sizing needed upgrades, replacement systems, and server consolidation.

Tivoli Application Dependency Discovery Manager (TADDM), also included with AIX Enterprise Edition, has been enhanced to:
- Improve support for WPARs
- Feed data from IBM Tivoli Monitoring for instant status changes and discovery of new LPARs
Management Edition for AIX included with AIX Enterprise Edition provides:
- Installation Launchpad: The launchpad provides the ability for customers
to locally install and configure all components of Management Edition for AIX.
New features for this component include:
- Automated checking of all component prerequisites
- Remote installation and creation of databases
- "How-to" videos explaining how to use various components of this offering to include capacity analysis and reporting topics
- Tivoli Application
Dependency and Discovery Manager: This component provides three key features:
- Discovery of the Power Systems physical and virtual environment and their dependencies
- Tracking of changes
- Providing change events and ensuring compliance of servers/LPARs against a "gold standard"
- IBM Tivoli Monitoring: IBM Tivoli Monitoring
provides performance and availability monitoring and alerts for the Power Systems
environment to include monitoring of these key Power Systems AIX components:
- VIOS: The VIOS agent monitors the health of the VIOS, provides mapping of storage and nw resources to the client LPAR, and provides storage and nw utilization statistics. The VIOS Premium Agent is preinstalled on a VIOS system.
- CEC: The CEC agent provides overall CPU and memory utilization of the frame for monitored partitions and provides CPU and memory utilization by LPAR. The CEC agent must be installed on an AIX partition that resides on the CEC to be monitored.
- AIX Premium Agent: The AIX Premium agent provides statistics for each LPAR-CPU (entitled, physical, and logical), memory utilization, disk, and nw utilization and process data. This agent also provides usage statistics for WPARs as well.
The HMC agent provides health and availability of the HMC. Multiple instances of the HMC agent can be invoked on the same partition to monitor multiple HMCs. New features for this component include:
- Integration with IBM Systems Director: This will provide IBM hardware customers with monitoring and management from one UI, which will provide for reduced mean time to repair. This integration provides the capability to contextually launch IBM Systems Director from IBM Tivoli Monitoring to perform configuration changes/start/stop LPARs and perform other actions.
- Storage Utilization by LPAR (VIOS): The VIOS Storage Mapping workspace was enhanced to include disk transfers related to the client partition. With this feature, the customer is able to easily view storage utilization by LPAR, reducing mean time to repair.
- NPIV Client/Server Mappings (VIOS agent): Virtual Fiber Channel Adapters make use of an industry standard called N-Port ID Virtualization (NPIV), which allows enabled Fiber Channel adapters to be configured with 64 virtual ports. A new workspace in the VIOS agent provides the name of the physical port, the number of virtual ports, and the number of available virtual ports. This workspace also maps the client partitions to the physical and virtual NPIV ports. There is also a situation to indicate a low number of available virtual ports. This data provides the ability to understand how the Fiber Channel is being used by the LPAR. The available number of ports data indicates whether additional ports/FC are required.
- Shared Pool Data (CEC and AIX Premium agents): In the CEC agent, customers are now able to view statistics for multiple shared pools to include pool ID, CPU units consumed, number of LPARS using the pool, available CPU units in the pool, and pool entitlement and maximum pool capacity. Customers can sort the LPAR utilization table by shared pool ID to understand usage of the pool by the LPAR. There is a situation that provides an alert if the number of available CPUs in the shared pool is low. The AIX premium agent also provides the pool ID in the system work space. With this feature, the customer is able to determine which LPARs are using CPU from the shared pool and whether more CPU should be assigned to that LPAR.
Hypervisor Time (AIX and VIOS agents): An attribute and situation were added to the AIX premium and VIOS agents to indicate the CPU time the LPAR spent in the hypervisor. It provides the amount of time the hypervisor is spending to troubleshoot when excessive CPU is due to the number of hypervisor calls, and so on.
New Performance Analyzer: This new component was added in the 1.2 release of Management Edition for AIX. This feature extends IBM Tivoli Monitoring data to predictive trending to manage performance over time. It provides the ability to forecast resource trends to focus monitoring on emerging problems and leverage the long-term historical and real-time data in Tivoli Data Warehouse.
New Tivoli Common Reporting: This new component was added in release 1.2 of Management Edition for AIX and provides the ability to report on historical and predictive trends. This feature includes out-of-the-box reports that provide an understanding of utilization for all frames in the environment, for all LPARs in a frame, how LPARs are using the shared pool, top and bottom LPAR utilization, and other reports.
