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

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

18

Benefits of Virtual Infrastructure for High Availability

• Lower cost• Flexibility in use of physical hardware

• Planned hardware maintenance downtime eliminated by VMotion

• Simpler to implement• Flexibility in clustering and failover allows choice of best fit for each

environment

• Easy to activate availability features like NIC teaming,

• Greater reliability• Redundancy features of best physical systems

• Clustering options with virtual machines make it possible to cluster more applications and systems

19

Backup Options for Virtual Infrastructure

1. VM-based backup agent

2. Backup entire VM with backup agent in Service Console

20

Backup Agent in Virtual Machine

• Backup agent in each VM

• Functionality identical to physical machines with installed backup agents• Allows for file level and system

state backup

Tape Array

Backup Server

21

Backup from Service Console

• Backup agent resides in the Service Console

• Capture a complete .dsk or .vmdk file representing a virtual machine

• Reduces overhead on individual VM’s

• Requires virtual disk to be quiesced before reboot

Replication Options

• SAN based replication (Block-based)• e.g. RVM, PPRC

• IP based replication (File-based)• e.g. Replistor (Legato)

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

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

26

Physical to Virtual Recovery Preparation

P2V Assistant performs all necessary substitutions to transform a physical system into a production-ready Virtual Machine

Create

• Creates an image of the source machine using either the VMware imagining tool or a 3rd party imagining product

• Performs all necessary HAL and driver substitutions to make the image bootable

• User can manually modify any additional settings before having a production-ready system

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

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

Automated VMotion based on Hardware PFA

48

Automated VMotion based on Hardware PFA

• Event action plan to run VMotion triggered by hardware PFA reported by VMware ESX Server host1. Create a new event action plan

2. Using Event Action Plan Builder wizard, specify the hardware PFA event(s) for filtering• Disk error, fan speed, CPU temperature, memory bit errors

3. Associate the hardware PFA event(s) with the event action plan (drag-n-drop)

4. Define the action for migrating VMs from the failing host to the backup host• Use Customize Action dialog box

5. Associate the action with the event action plan (drag-n-drop)

6. 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
