Background:  I am trying to make my server more power efficient.  Right now its consuming 60 watts 24/7.  The server is only used a few hours a day.  In sleep mode it only consumes about 5 watts. 

 

I am running unraid 4.7

 

I have read the posts for putting the system to sleep by polling the HDD spinup/down status.  I feel confident I can automatically put the system to sleep automatically.

 

Now for the wakeup.  I have the WOL magic packet working great.  I can send the system "echo 3 >/proc/acpi/sleep" and it goes right to sleep.  Then with the depicus wolcmd I can bring the system right back up.

 

Has anyone had success with waking the unraid server with something besides the MagicPacket?

 

I did some reading and discovered that ethtool has other options besides WOL w/magicpacket.  When I do ethtool eth0, ethtools says my system supports p|u|m|b|a|g.  With pumbag being: 

 

wol p|u|m|b|a|g...    Sets Wake-on-LAN options.

    p    Wake on phy activity

    u    Wake on unicast messages

    m    Wake on multicast messages

    b    Wake on broadcast messages

    a    Wake on ARP

    g    Wake on MagicPacket

 

Does anyone have anymore knowledge on what wake on unicast|multicast|broadcast|ARP do?

 

I did some experimenting on my system with setting other than g.

 

p    Wake on phy activity

the system goes to sleep and immediately wakes up.  If i disconned the ethernet and issue the sleep from the console, the server immedately wakes back up when i plug the ethernet back in.

 

a    Wake on ARP

The system does not wake back up.  However, I dont really understand what ARP is.  I searched the internet and found little.  Or what I did find, I did not understand.

 

u    Wake on unicast messages

System goes to sleep, then a few minutes later, it wakes back up.  I assume the router is sending out some sort of unicast message.

 

I did find this post:

It might be your bios setting. If the motherboard supports s3 and wol, for wol it has bunch of options. You need to disable wake up on message, device ........ and just keep the option 'Wake up on lan/network.

My motherboard is a Supermicro x7spa-hf.  There is very little in the bios about WOL features
