I'm looking into the possibility of
using Wake On Lan for a machine used in a test lab to run VMs. It doesn't really need to
be on all the time, so it would be nice to be able to power it down when it's not being
used to save electricity.
Looking
through Dell's href="http://support.dell.com/support/edocs/systems/pe2950/en/engbrief/wol.pdf"
rel="nofollow noreferrer">WoL support documentation, the NIC (Dual Embedded
Broadcom® NetXtreme II 5708 Gigabit Ethernet NIC) should supposedly support WoL. The doc
is a little old, though, and doesn't discuss Server 2k8, much less 2k8
R2.
Nevertheless, one of the steps in the Server
2k3 configuration details specifies that hibernation support should be enabled; however,
when going into the power options for my server, there are no hibernation configuration
options in the gui.
I should note that my
understanding of WoL is fairly weak. Do systems monitoring the network for magic packets
need to be explicitly hibernated, and not shut off as normal? I wouldn't think that the
way the OS shut down the system would affect the motherboard's ability to run power to
the NIC, but then again this is not my area of
expertise.
I will assume for now that
hibernation is specifically required. Looking around some more, there seems to be
indication that hibernation is not supported for systems that run the Hyper-V
role--something to do with the Hypervisor. If this is true, it means that my desired
configuration would be impossible. Can anyone provide confirmation or additional detail
about this?
I don't
know this Dell system, but in all systems I know, you need to turn on WOL in the BIOS.
Hibernating Windows would then help with the boot time, but is not required per se.
