AIX Workload Partitions (WPAR)

� WPARs are designed to save administrator work by reducing the number of AIX instances to patch

� WPARs have much lower memory resource requirements: 68 MB vs 1GB for an LPAR

� WPAR takes seconds to create and LPARs minutes

� Application mobility much simpler to organize than LPM

� Lots of WPARs on one AIX is simpler to monitor and control than monitoring across many LPARs.

� Rapid cloning is easy and lets you use "disposable images" -simple to create, experiment and throw away

�Virtualized AIX operating system environments within a single AIX image

�Each WPAR shares the single AIX operating system

�AIX 7 added the capability to run AIX 5.2 in a WPAR*

�Applications and users inside a WPAR cannot affect resources outside the WPAR*

�Each WPAR can have a regulated share of processor, memory and other resources

�Two types of WPAR

- System WPARs have separate

security and appear like a

completely separate OS

- Application WPARs are

manageability wrappers around a

single application

Top reasons to use WPARsWhat is it?

* Requires purchase of the AIX 5.2 WPARs for AIX 7 product

PowerVM Live Partition Mobility

�Can make it easier to consolidate workloads from underutilized servers by facilitating the transfer of workloads with almost no end user impact

�Can provide increased flexibility to manage workloads by easily moving the workload to another system

�Facilitates increased reliability by allowing workloads to be moved away during planned outages

�PowerVM Live Partition Mobility can provide for a much more flexible and responsive IT infrastructure by reducing the cost and risk of rebalancing workloads

�A PowerVM Enterprise Edition feature that allows an entire Logical Partition (LPAR) to be relocated from one system to another with almost no impact to the end user

�The end user effect is a single delay of two seconds when the relocation is completed

�Supported by AIX 7, AIX 6, AIX V5.3 and Linux®

�PowerVM Live Partition Mobility requires that all I/O be virtualized through the Virtual I/O server at the time of the relocation

How it can help?What is it?

Movement to adifferent server with no loss of service

Virtualized SAN and Network InfrastructureVirtualized SAN and Network Infrastructure

Live Partition Mobility requires the purchase of the optional PowerVM Enterprise Edition.

Virtualized SAN and Network Infrastructure

PowerVM Live Partition Mobility

• Move an entire Logical Partition from one system to another while it is running with almost no impact to end users

• Moves the entire LPAR including the operating system

• Requires systems based on the POWER6 or POWER7 processors, PowerVM Enterprise Edition, and all I/O must be through the Virtual I/O Server

• Works with partitions running AIX 7, AIX 6, AIX V5.3 and Linux

Live Partition Mobility

�The capability to dynamically extract information about a program as it is running

�Trace points can be added or removed dynamically without recompiling or restarting the application

�Includes a new language, vue, to define the desired action when a probe point is reached

�Support for C, C++, FORTRAN and Java language programs

PowerVM Workload Partitions Manager for AIX

�Can make it easier to consolidate workloads from underutilized servers by providing a single point of management for all WPARs and enablement for Live Application Mobility

�Can reduce cost and complexity through centralized management of WPARs

�Enables increased flexibility by allowing administrators to quickly create, clone or delete Workload Partitions from one system to another

�Supports systems based on POWER4 or later processors

�Policy based relocation and federated management of WPARs provides new ways to manage your IT infrastructure

�A product that federates management of WPARs across multiple systems

�WPARs can be created, cloned, stopped, started and monitored from a single location

�Includes enablement for Live Application Mobility

�The WPAR Manager is a advanced manager “plug-in” to the IBM Systems Director

�The WPAR Manager is available as a component in the AIX Enterprise Edition or as a separate product

AIX Automatic Variable Page Size

�Can improve overall system performance which could improve the amount of work done per Watt of energy

�Automated page size tuning can reduce the amount of effort and cost associated with managing a key aspect of performance tuning

�Since this feature is turned “on” by default, it improves your ability to get the most out of your systems based on POWER6 processors

�This “self tuning” aspect of AIX can improve performance while reducing administrative workload

�AIX exploitation of POWER6 or later hardware that supports variable page size

�AIX will automatically select optimal page size to provide better performance

�Kernel will choose between 4K and 64K pages, including a mix within a memory region

�Supports process data, heap, stack, shared memory, anonymous mmap() memory

�Enabled by default with administrative controls to turn off or change aggressiveness to “upsize”

�Required AIX 7 or AIX 6 and POWER6 or later processor based systems

AIX Systems Director Console for AIX (pConsole)

�Can reduce the amount of effort and cost associated with managing the AIX OS

�Web access to administrative tasks can simplify systems management

�Consistent user interface with IBM Systems Director and the WPAR Manager can reduce retraining and other administrative costs

�The combination of Web access to administration tools and the ability to execute administrative tasks on multiple systems can change the way you manage the AIX OS

�A Web based management tool that provides easy access to common system administration tasks

�Administrators can access Systems Management Interface Tool (SMIT) menus from a browser

�Graphical user interface is fast and fully integrated with IBM Systems Director

�All necessary components for the Console are included in AIX

�The Distributed Command Execution Manager (DCEM) feature of the Console allows an administrative task to run on multiple systems at once

Why should you move up to AIX 7 or AIX 6?

� More performance on POWER7– AIX 7 and AIX 6 can provide substantially more performance on POWER7 than AIX V5.3

– AIX 7 supports massive workloads with up to 256 cores / 1024 threads

� Access to new features– Capabilities like WPARs, Role Based Access Control, AIX Profile Manager are designed to

improve security and administrative efficiency

� AIX V5.3 is nearing End of Life– End of Marketing announced effective April 2011

� AIX 7 will support running AIX 5.2 in a WPAR– Excellent way to consolidate old workloads running on less efficient hardware

� It’s FREE!– Customers with software maintenance agreements (SWMA) can upgrade for no additional charge

within an Edition:

• AIX 5.3 to AIX 7 Standard edition

• AIX 6 Express Edition to AIX 7 Express Edition, etc,
