Why Virtualize Workloads With PowerVM? Creating a virtualized workload with PowerVM is simple: Create a new PowerVM logical partition (LPAR) or virtual machine (VM) Install the operating system (AIX, IBM i or Linux) in the VM Install the workload application(s) in the VM Configure the operating system and applications as required At this point, the completed virtualized workload can be stored, copied, archived or modified just like any other file The benefits of virtualizing workloads with PowerVM in this way include: Rapid provisioning deploying the ready-to-run workload is a quick and easy process Scalability deploying multiple copies of the same workload type is simplified Recoverability bringing a workload back online after an outage is fast and reliable Consolidation many diverse workloads can be hosted on the same server All of these benefits save system administrator time and resources In addition, workload consolidation offers significant IT infrastructure cost reductions 4

AIX Workload Partitions (WPAR) What is it? Virtualized AIX operating system environments within a single AIX image Each WPAR shares the single AIX operating system 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 AIX global Instance Workload Workload Partition Partition Application Billing Server Workload Partition Workload Test Partition Workload Web Partition Server BI Top reasons to use WPARs WPARs can 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 Two types of WPAR 8 - System WPARs have separate security and appear like a completely separate OS - Application WPARs are manageability wrappers around a single application Disk or NFS storage Networks 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
AIX 5.2 WPARs for AIX 7 How does it work? Client simply backs up existing legacy AIX 5.2 environment and restores into an AIX 7 WPAR The AIX 5.2 environment including rootvg filesystems are preserved and restored Client applications continue to run in AIX 5.2 environment with AIX 5.2 libraries The kernel environment will be AIX 7 SMT4, MicroPartitioning and VIOS are supported!
