IBM System p © 2008 IBM Corporation Two Workload Partitions Types Create Stop Run Remove Defined Active Application Workloads –Isolate an individual application –Light-weight, one process Can start further processes –Created & started in seconds –Starts when created –Automatically removed when application stops –Shares global file system –Good for HPC Long running applications Create and run Stop and remove System Workloads – Complete virtualized OS environment Runs multiple services & applications – Needs to be created as it builds its filesystems – Removed only when requested – Like another AIX system 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 – Integrated with RBAC - granular security controls

IBM System p © 2008 IBM Corporation 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 Create Stop Run Remove Checkpoin t Restart NFS for WPAR private filesystems & the statefile Defined Active
