Back in September for VMworld 08 a team of engineers at VMware setup a demo to showcase VMware's power management features. This demo drives a heavy, mixed workload for an eight-hour day and shows metered power usage throughout. The workload used was VMmark and the total power savings were over 55%! This feature (DPM) is available experimentally in VI3 and will be fully supported with the next release.

Great demonstration and logic

1 - Do You really know what is standby?
2 - Depends on many things, not only on vitualization. But - economic question - Have You seen, how many servers were virtualized? Imagine it on hardware servers...
3 - Vmware does not upgrade cluster on the fly, All the 4 servers are already in a cluster, You don't change config or depencities.
4 - Storage fabric will not see much. Just patches to some wwn's will be not used.
Have You tried to use VMware?

4. Scalability issue.
We have to use a SAN and disk array in this case. Any time a server is on/off, the storage fabric will see a member join/leave and will do a lot of work. Although the VM movement may hitless, the fabric changing by server power on/off are most like disruptive. In a storage world, it is a bad idea to power on / off the member frequently. if the servers are much more than 4, how to keep SAN fabric stable using today's technology?

3. Safety and management question:
Is automatically power on/off server in a datacenter a good idea? What VMware does is like an cluster upgrade on-the-fly. Even with qualified sys-admin, the best practice is those changes should be done in mid-night, not 9:00AM in the morning, and 11:00 at peak hours. VMware DRS asks us to make some dramatic changes in management polices.

1. Hardware question:
What is the impact for hardware mortality rate because of frequent power on and power off ?
2. Economic question:
In a 4 server case, what is real OPEX when considering power cost saving and hardware maintain increase ?
