16. VMotion: Online Virtual Machine Migration
• Enables real-time online migration
of running virtual machines
• Persistent connection throughout
migration
• Can be automatically initiated when
• Critical alarm is generated for the host
hardware
• Host hardware utilization exceeds
specified level
• It is time for the scheduled maintenance
16

17. VMotion Raises Workload Availability
VMotion enables zero-downtime maintenance and workload
management
• Temporarily free
servers for
hardware
maintenance
• Dynamically
rebalance
workloads to
servers with more
computing
bandwidth
17

18. Benefits of Virtual Infrastructure for High Availability

23. Replication Options
• SAN based replication
(Block-based)
• e.g. RVM, PPRC
• IP based replication (File-
based)
• e.g. Replistor (Legato)
23

24. Recovery Options
• Physical to Physical
• Existing scenario without Virtual
Infrastructure
• Physical to Virtual
• Reduces cost, improves time to
recovery, and increases flexibility
• Virtual to Virtual
• Greatest flexibility, lowest cost, best
time to recovery
24

25. Physical to Virtual Recovery
• Virtual Machine templates with
operating systems and backup agents
are created and archived
• Full system restore occurs into Virtual
Machine using existing recovery agents
25

26. Physical to Virtual Recovery Preparation
P2V Assistant performs all necessary substitutions to transform
a physical system into a production-ready Virtual Machine
• Creates an image of the source
machine using either the VMware
imagining tool or a 3rd party Create
imagining product Source Image File(s)
Physical System
• Performs all necessary HAL and
Virtual Disks
driver substitutions to make the
image bootable
• User can manually modify any
additional settings before having a
production-ready system VM Host Virtual Machine

28. Virtual to Virtual Recovery Options
• Same as physical to physical: Replicate backup and
recovery process on all virtual machines…
• OR
• System-level capture and recovery
• Manually copy virtual machine file to a different location
• Use a backup agent installed in the ESX Server console or on the
host OS
• Shared storage
• In case of a hardware failure, recover virtual machine from shared
storage to a different physical system
• Disk / LUN replication
• Run disk replication from inside the VM
• Run storage array based replication
28

29. Recovery with Shared Storage on SAN
• Hosting VMs on SAN
increases system
availability
• If for any reason
hardware hosting virtual
machines fails, VMs can
be restarted on a
different platform.
• The only downtime is
time required for VM
booting

2. Using Event Action Plan Builder wizard, specify the hardware PFA event(s) for
filtering
• Disk error, fan speed, CPU temperature, memory bit errors
1. Associate the hardware PFA event(s) with the event action plan (drag-n-drop)
2. Define the action for migrating VMs from the failing host to the backup host
• Use Customize Action dialog box
1. Associate the action with the event action plan (drag-n-drop)
2. Associate the new event action plan with the host to be monitored for hardware
PFA (drag-n-drop)
• IBM Director Agent on failing host will detect PFA and pass the alert
to IBM Director Server
• IBM Director Server will invoke the enabled event action plan through
VMM
• VMM communicates with VMware VirtualCenter to invoke VMotion of
VMs from failing server to backup server
