8 Workload Partitions and Resource Management

� AIX Version 7.1 Enhancements

– Trusted kernel extension loading and configuration

– Export of fiber channel adapters to System WPARs

– Support for VIOS disks in Workload Partitions

– Versioned WPAR type (AIX 5.2 WPAR for AIX 7 LPP)

� Partitioned System Capacity

– Each Workload Partition obtains a regulated share of system resources

� Two Types of WPAR

– Application WPARs are manageability wrappers around a single application

– System WPARs have separate security and appear like a completely separate OS

� Resource Controls for WPAR

– CPU, physical & virtual memory, number of threads and number of processes

� Shared System Resources

– OS / Shared Library and Text / Processors

AIX 5.2 Workload Partitions for AIX 7 (5765-H38)

AIX 5.3 Workload Partitions for AIX 7 (5765-WP7)

� New LPP offerings simplify migration of

AIX 5.2 or AIX 5.3 workloads to POWER7

– Run on top of AIX 7 and POWER7 processor-based server

� Customer value

– Simplify consolidation of old workloads on new hardware

– Reclaim floor space and eliminate hardware support for obsolete servers

– Protects customer investment in application stacks

– Offering includes phone and fix support for AIX 5.2 or AIX 5.3 respectively

– Enables advanced capabilities such as SMT4, Live Application Mobility and Live Partition Mobility

– Provides a way for AIX 5.2 or AIX 5.3 clients to move up to POWER7

� AIX levels supported are final service packs of final TLs: 5200-10-08 or 5300-12-04

� SWMA provides limited support for AIX 5.2 or AIX 5.3 including phone support and limited new fix

support

– Fix support is limited to security, data integrity problems and critical issues and may not always be possible

� WPAR restrictions apply:

– HACMP support only for the global instance

– NFS server not supported in a WPAR

– Device support is limited to devices directly supported in WPAR (and on POWER7)

– Because the performance commands and libraries are used from AIX 7, applications that are sensitive to output from these commands may not work

� SAN and virtual SCSI Devices are allowed inside an AIX 5.2 or AIX 5.3 WPAR


Power System


Versioned Workload Partition Architecture� Versioned WPAR Environment (VWPAR)

– Created by global admin from mksysb image

– Appl. stack is not modified: 5.2/5.3 libraries are used

� Versioned WPAR Administrative Model

– Same administrative model as native WPARsUses mkwpar, startwpar, ...

– New -C command argument to mkwpar to specify

alternative runtime environment

– Additional software (vwpar.images.base, vwpar.images.52/53) installed into 5.2/5.3 WPAR

� System call compatibility logic (not layer)

– Some sys calls require VWPAR-specific logic

– Maps input, output parameters, and return codes according to legacy semantic

– Transparent to appl. & wholly contained in kernel

� Access to Native OS Support

– Code is mounted from native runtime environment

– Commands which must be at level of native runtime environment replace AIX files inside VWPAR.

– Includes configuration methods, ODM, LVM, FS, a few libraries, and performance commands
