IBM System p Live Application Mobility Moving a running Workload Partition to another machine or LPAR 1. Installing new machine • Moving a WPAR very fast way to take on work 2. Multi-system workload balancing • IT optimization to maximize CPU, memory, I/O effectiveness 3. Empty a machine for application outage avoidance • Green computing, Upgrade machine (AIX or firmware) or for Repair AIX # 2 AIX # 1 Workload Partition EMail Workload Partition Web Workload Partition App Srv 1.

IBM System p Two Workload Partitions Types Create and run Create Remove Run Defined Stop Active Stop and remove Application Workloads System Workloads – Isolate an individual application – Complete virtualized OS environment – Light-weight, one process – • Can start further processes Created & started in seconds • Runs multiple services & applications – Needs to be created as it builds its filesystems – Starts when created – Like another AIX system – Automatically removed when application stops – Shares global file system – Good for HPC • Own root user, users, and groups • Own services like inetd, cron, syslog • Can be stopped and restarted – Does not share writable file systems with other workload partitions or the global system • Long running applications – Removed only when requested – Integrated with RBAC - granular security controls © 2008 IBM Corporation

IBM System p Workload Application Mobility = Relocate § For Application Mobility – On WPAR Manager select WPAR, click Relocate, select target AIX = Done § Underlying commands are – Checkpoint WPAR : chkptwpar –k • Freeze WPAR, save the WPAR processes & state to a statefile on NFS • Kill the WPAR processes once they are no longer needed – Restart WPAR : restartwpar • Take the statefile, rebuild the WPAR processes & state and start the WPAR Defined Stop Active in t po ck he C rt Remove Run Re sta Create NFS for WPAR private filesystems & the statefile © 2008 IBM Corporation
