“ Live Partition Mobility allows you to migrate LPARs running the AIX operating system and their hosted applications from one physical server to another without disrupting the infrastructure services.” © Copyright IBM Corporation 1994, 2013 Live Partition Mobility

IBM Power 6/7 system  Chassis is divided into servers.  Servers run on power7 CPUs, RAM, & OS.  Servers contain Linux partitions that house multiple Virtual Servers.  Consequently, operating systems must be Linux based.

Live Partition Mobility The process of moving an LPAR between two Power Systems servers is called a MIGRATION

What is an LPAR ? LPAR stands for Logical Partition  The division of a computer processor’s memory and storage into multiple sets of resources.  Each set can be operated independently with its own operating system and applications.

2 Types of Partition Mobility  Active Partition A running LPAR is migrated without disrupting the operation of the OS and applications running in that LPAR.  Inactive Partition Migration A partition that is logically ‘powered off’ (not running) is transferred from one system to another. Networked applications may see a short (~2 second) network blip.

What are the problems? The need to upgrade a physical server The need to take a server down for maintenance The need to consolidate servers The need to replicate servers The need to rebalance workloads across systems

Live Partition Mobility allows you to migrate entire system environments from one server to another, while they are running, without disrupting the infrastructure services. The operation is completed in minutes.

Virtualization is the key  Virtualization, in computing, refers the act of creating a virtual (rather than actual) version of something, including but not limited to a computer hardware platform, operating system (OS), storage device, or computer network resources.

Benefits of Virtual Live Partition Mobility  Reduce Downtime - Re-locating LPARS & applications from server to server.  End - Users are unaffected and unaware of the transfer.  Virtual Servers can be transferred back to their original server.  Reduces energy consumption Consolidate workloads and turn off unused servers Reduce power to run machines keeping them cool during off-peak periods

Live Partition Mobility for New or Unexpected Events One of the most time consuming activities in a complex environment is the transfer of a workload from one system to another. Migrations via Live Partition Mobility can assist to meet needs in within the following areas:  Deployment of a New System A workload running on an existing system must be migrated to a new, more powerful one.  Replacement of faulty hardware

Live Partition Mobility in Routine Operations  Avoiding a system shut-down during routine activities.  Maintenance Replacement of Memory Card  Resource Balancing & Workload Consolidation Servers might be starved of adequate CPU power when others have increased levels of activity.

Workload Consolidation “The first goal of server consolidation is to virtualize and migrate workloads so you can optimize and balance performance using fewer physical resources” © 2011 Novell, Inc

LPAR Profile  Describes what resources an LPAR will have available when it’s powered on. CPU Virtual CPU Memory Physical I/O Adapters Virtual Adapters

Virtual I/O Server  Consolidates multiple AIX Systems under a single System P server; maximizing return on disk and network resources.  Virtual I/O (VIO) technology was introduced by IBM  Allows the same LPARS to use the same storage and network resources, breaking the barrier of disk and adapter isolation.

Migration via HMC The 5 Main Steps are initiated through the Hardware Management Console (HMC). HMC is Graphical interface

HMC Display ( LPARs setup)

Live Partition Mobility – How it Works Steps:  1. It takes contents from running LPAR  2. Duplicates Features and Identity  3. Sends Duplicate to Destination system  4. Swings everything over  5. Ties with original server are cut
