I recently piurchased a Ml110 G7 server and am really pleased with the build quality.
I have come across a slight issue though.. The fan speeds it constantly running at 50% and there really is no need for it to be that high.
I nstalled ESXI 5 on the server and installed this to a 2.5" drive (there are currently no drives in the bays) and it works fine.
When I first turned the server the fans were fine and I could barley hear it. After a day or two I noticed they had increaded in speed and noise.
I then did a bit more digging and installed the HP Esxi offline bundle and after a restart the fans returned to normal but again after a day or two that have increased in speed again.
A restart does not lower them and they start at 50% speed.
ESXI reports: Fan 1 @ 55%, Fan 7 @ 50% & Fan 8 @ 10%
When all is running good fan 7 is @ 30% , fan 7 at 30% and fan 8 @ 10%.
Is there anyway to constantly set the fans at these speeds? Or what could be causing this?

I do believe the latest firmware in on the Mobo yes.
But the server does not have the Ilo port. I believe the software is present but disabled as the port was an extra that didnt come with the server. Am I correct in thinking this or do I need to update it anyway?
08-13-2012 01:41 AM
The server has iLo 3. It's a good idea to check/update the FW. Do you have some PCI cards installed in the server?
08-14-2012 01:05 AM
I ran the proliant service pack and it found two updates that needed doing.
After a restart this made no difference. I then accidentally hit f5 on start up and it took me to the Ilo3 bit.. As I don't use this I decided to disable it. Instantly the fans dropped to the correct speeds.
I then went out for an hour or two and when I returned the fans were back running far too loud.
This is really annoying when they run normally its a perfect server.

I'm getting the same problem. Lots of advice on this thread:
See if any of those help. None worked for me :o(

iLO manages the overall system health monitoring and status. it talks to System BIOS and other components on the MB to get the status of each device.
So please enable the iLO and check the firmware version and update it to the latest if available.
Please let me know if it makes any difference.

The Ilo firmware is up to date acceptors to the proliant service pack which was released in June.
I will re-enable Ilo tonight and see if it makes any difference which I doubt it will as it was enabled before.
I also don't have an Ilo port on the server. I believe its just the software that is installed on the server.
If I bought the Ilo port would it help? / give me more options on fan management?
I hope we can get to the bottom of this as its ruining a really good bit of hardware.

Is this a brand new unit? Does it have two network ports on the back next to each other? If so then the one labelled '1' is your iLO port.
If you have this port and you're connected to the network via it, you can run a browser on a PC on the network, and access the iLO on the server via the IP address in the iLO config using the user name and password printed on the label on the back of the machine.
08-15-2012 04:53 AM
It is a new unit purchased the other week.
Ah I emiled the company I purchased it from as I expected it to come with an Ilo port. I can see where it should be but there is a blanking plate there. So I never really looked in to it as I didn't need it.
But as I say Ilo was working before and the fans were still running high. Just had a look this morning remotely and they are still at around 10%, 50% & 50% just glad im not currently sat next to it!
Would any 3rd party tools be able to control the fan speeds? I have seen some for desktops computers but not heard anything for servers.. Not I would look for it but im getting desperate now!
08-15-2012 11:49 AM
This probably makes me sounds a bit dim.. But im having great trouble getting the Ilo back up.
My plan was to go back in the f5 menu and enable it again.. But this keeps bouncing me saying I have to go through f8 to re-enable it.. Only f8 isnt doing anything...
Can someone let me know how to re-enable the Ilo 3 interface please.
08-15-2012 02:22 PM
You have to set dip switch number 1 to 'On' on the motherboard then reboot and start pressing F8 as the system is booting (when the HP logo is displayed). Keep repeatedly hitting the F8 key.

Is the drive you installed a HP hard disk?
I have read that the fans run faster because the server cannot properly monitor the drive temperature in compatible non HP drives
Having said that, I am using a ml110g7 with 4 3.5 sata non HP drives with no issues at all. 2 are constellations, but the other 2 are cheaper hitachi
08-15-2012 03:54 PM
The drives currently installed are not HP ones.
When I get some time I will have to try migrating the ESXI install on to the HP disk and seeing how that runs.
I have just re-enabled the Ilo and the web interface is reporting all the fans have dropped in speeds.
Fan 1 @ 33%, Fan 7 @ 10%, Fan 8 @ 10%. Barely a sound out of it!
I will leave all the ESXI servers off tonight and see how the fans are doing in the morning with the server not doing anything.
But I refuse there is not a fix for this.. After all it is a entry server and most businesses that buy this don't have dedicated server rooms to hide it off in!
08-15-2012 03:59 PM
That's what happened when I reset the iLO. 10 minutes later back to 50% :o(
I've tried running with just the one drive in it that came supplied with the unit: still runs at 50%.

Here's another question:
If I replace all the fans with 5v ones running off the PSU will iLO go mad and shut the server down?
If that is the case will disbling iLO stop the server monitoring the fans?
Will doing the above invalidate my warranty?
Will hitting the case with a big stick help, because I'm close to that point now.
08-16-2012 01:40 AM
The big stick also helps!
Well the fans are sticking at the correct speeds.. and have been all night.
I left the server running with no ESXI servers running last night and the fans were still the same speeds this morning. I then started two servers and the fan speeds have not changes so all seems good for now.
What I did was:
Go to the F9 setup screen and disable the logo boot
Update to the latest fimware with the prolient service pack.
Restart the server and Hit F5
Disable everything you can from this screen (disabled ILO)
Restart the server (once or twice)
Shutdown the server
Enable the override switch on the mobo to position 1
Turn the server on and hit F8
Enable ILo and all the options (I also set up an IP for it this time)
Save and exit this part.
Shutdown the server (I help the power button in)
Turn the override switch back to 0
Turn the server on and make sure ILO it running. (Mine showed the IP I set)
Once the server is on head on over to the ILO page and see what the fan speeds are.
If they are correct just leave it for a while with out starting any ESXI servers and see if they stay the same.
This seems like a really long way of doing it.. and included my mistakes but it seems to be holding steady so maybe there is some magic in my ways...
I will keep you updated on if it holds.

Guess I spoke too soon.
Been working on the ESXI servers for a few hours now and fan speeds have gone back to how they were.
This looks to be ESXI's doing?
Are you trying to run ESXI on your Ml110?
08-16-2012 05:28 AM
No, not trying to run ESXI on my ML110. If I reset the iLO it runs silently for a while then picks up speed again.
Been doing more Googling and a common official response to this problem seems to be that its operating this way by design.
I'm convinced the cooling is excessive. Considering getting hold of some cheap alternative fans and running them off the PSU so I can control the fan speed independantly. Worried however that iLO is going to think that as it doesn't recognise the fans that it will shut the server down.
08-16-2012 05:57 AM
Have checked the temps when fans running at 31%/13%/10% after iLO reset then again after running for an hour after they've picked up to 54%/46%/10%. The temperature reduction doesn't warrant the extra noise, electricity or wear and tear IMHO.
Have attached the results - first 'Reading' column is 31%/13%/10% second is 54%/46%/10%.
08-16-2012 06:00 AM
I agree it does not warrent the noise and its really starting to bug me now.
I have been playing around with ESXI as it was fine till I started playing with it. But I have updated the to the latest esxi bundle with no joy.
There must be a simple solution to this. What OS are you running?
Possibly try your fan solution it might be the only way. I think its the front fan under the drives that is causing the problem.

Just spend ages on the online support bit with HP talking to a guy..
He assess me this problem is with the power state of the server but I am not at home to test it.
Nick can you let me know what you have yours set to?
Power Management settings in the Bios.
Mine currently looks like this:
HP Power Profile: Custom
HP Power Regulator: OS Control Mode
Advanced Power Management Options \ Minimum Processor Idle Power State: C6 States
I am going to change the Power regulator to Dynamic and see if that helps. (He assess me it will)
08-16-2012 09:29 AM
HP Power Profile = Balanced Power and Performance
HP Power Regulator = HP Dynamic Power Saving Mode
Advanced Power Management Options \ Minimum Processor Idle Power State = C6 State
