Dynamic Partitioning (DLPAR) • DLPAR is the ability to add, remove, or move resources between partitions without restarting the partitions • Resources Processors, memory, and I/O slots Add/remove virtual devices

-

• Security and isolation between LPARs is not compromised

A partition sees its own resources plus other availablevirtual resources Resources are reset when moved

-

DLPAR allows you to react to changing resource needs

Multiple Shared Processor Pool Details Default, there is one virtual shared processor pool (pool identifier of zero) defined on the system. Maximum capacity of the default pool is the number of processors in the physical shared processor pool

Virtual shared pools are created from the HMC interface Maximum capacity of virtual shared processor pool can be adjusted dynamically Partitions can be moved between virtual shared processor pools Partition Mobility of a partition in a pool is supported When adding / removing a partition to a pool will increase / decrease the entitled capacity of the pool by the amount of the entitled capacity of the partition Multiple Shared Processor Pools as license pools for Oracle, Websphere, …..

AIX Workload Partitions Separate regions of application space within a single AIX image Improved administrative efficiency by reducing the number of AIX images to maintain Software partitioned system capacity Each Workload Partition obtains a regulated share of system resources Each Workload Partition can have unique network, filesystems and security

Two types of Workload Partitions System Partitions Application Partitions

Workload Partition Test

Separate administrative control Each System Workload partition is a separate administrative and security domain

Shared system resources Operating System, I/O, Processor, Memory

What is PowerVM Lx86??? Native Native Linux Linux on on POWER POWER Binary Binary

Linux x86 Applications ISV Binaries

User Binaries

Dynamically translates and maps x86 Linux instructions to POWER Run any 32-bit Linux/x86 user space application binary Requires no re-compilation Direct H/W access or apps using kernel mod’s not supported

Lx86 Feature Front End Optimizer Back End

Linux OS (Red Hat or Novell SuSE) POWER Processor Power System Server Platform 53

Native & translated applications interoperate Transparent to users “It just runs” like on Linux/x86

Performance: 60-80% of native

“Good Enough” for many apps Translates blocks of code into intermediate representation Performs optimizations Stores optimized, frequently used blocks of code in cache Handles Linux OS call mapping Encodes binary for target POWER processor platform

When to use PowerVM Lx86? Native port gives BEST performance Ideal scenarios for Lx86 feature

Application Considerations1 User Interactive

1. Proof-of concept project before native port 2. Initial “port” for appropriate and compatible applications to build business case

Transactional

3. Supporting applications, tools, utilities for your mainstream applications which are enabled as a POWER application running the Linux OS

I/O Intensive Computational Intensive

4. A fast means to test and characterize an environment for server consolidation of several applications Run AIX®, Linux on POWER and x86 Linux applications on one server

Not a good use for PowerVM Lx86
