I currently have Vmware ESXI 5 cluster with Dell Poweredge R710 hosts. I was told that its possible when a host goes into stand-by to have a "quick-boot" when it comes out. At this time I am waiting 7+ minutes. I have seen another cluster that boots out of stand-by in 30 seconds.

Is this a setting or part of IPMI or bios? If so how do i set this up?

Best way I can explain it Is i want the VM Host to Go to Sleep vs power off completely when in stand-by mode.

I think i might have found something – Sarge Oct 29 '12 at 13:26

This is part of the VMWare Distributed Power Management (DPM) functionality.

In your host config in the vSphere client, navigate to Configuration -> Software -> Power Management.

You can add your ILO/DRAC/IPMI settings in the resulting dialog.

Further configuration on policy definition is available in your cluster properties dialog... It's related to the DRS feature.

What version of VMWare licensing are you running?

ESXI 5.1.0, i already have the IMPI/iLO settings in place. – Sarge Oct 29 '12 at 13:33
I'm asking about your license... This is only available in Enterprise or greater licensing. – ewwhite Oct 29 '12 at 13:37
I am running Vsphere enterprise. I can use stand-by mode etc but its just slow. – Sarge Oct 29 '12 at 13:39
Check your server's BIOS settings and ensure that C-states and specifically, P-states are enabled. (see: S3) – ewwhite Oct 29 '12 at 13:41
I have no option for p-state control that i can find in the bios. C-State is enabled and the power management is under os control. – Sarge Oct 29 '12 at 13:57
