Royco 15 Posted August 4, 2014 (edited) Hello everybody. I'm new to the forum and this is my first post. I was wondering about the western digital red/Seagate Barracuda and "fan compatibility". I've installed three drives in my Microserver Gen 8: Raid 0 - Seagate barracuda 2TB (salvaged from different system) with OS Raid 1- Two Western Digital Reds 2TB I installed Ubuntu 14.04 and included the HPVSA linux drivers (and blacklisted AHCI). The drives are correctly recognized as 2 HP logical volumes and lsmod lists the HPVSA driver. When I access ILO and look at the HD temperature probe, the temperature is always 50 degrees Celsius (even after a cold boot). This seems rather high and suspect I get an incorrect reading. My fan spins around 20-30%. Can someone tell me whether the WD Red's give a good temperature reading and can give the low 6% fan speed? I'm considering pulling the Seagate drive and hoping to get a good temp reading from the WD. (Using dd now to clone my drive, will know more in 10 hours). I updated the ILO firmware to 1.51 and the BIOS is also recent (somewhere middle 2014, 06/06/2014?). Edited August 4, 2014 by Royco Share this post Link to post Share on other sites
Royco 15 Posted August 5, 2014 I was forced to re-install Ubuntu and now I get a nice HD max reading of 35 degrees Celsius. However, the fan still spins between 20-30%. If there's a member with 6% fan speed, could they perhaps share their ILO temperature measurements? Maybe I've another hot component and this would help me identify it.

If there's a member with 6% fan speed, could they perhaps share their ILO temperature measurements? Maybe I've another hot component and this would help me identify it. To get 6% the server needs to be set in the cooling mode in the bios that's the top option. You probably will find you are set in another. I have an ambient of about 28C today my box is sitting at a low 7% and when I'm down to the usual 18 - 22c it drops to 6% and even sometimes when it goes below 12c here the fan stops and goes to 0% for periods of 20 - 30 minutes.

Royco 15 Posted August 6, 2014 Those are impressive numbers. Do you mean the HP power profile setting in the BIOS? Balanced power and performance would be the top option. I also had a discussion at the HP forum (see here) and found my issue was not Ubuntu specific. Could my PCI graphics be the problem (Sapphire HD5450)? There is a topic at HP about the fan and PCI (see HP ML350e Gen8 Fan Noise). They remove a PCI card and the system becomes quiet. I'm sure people use non-HP parts in the PCI slot and they should have similar problems, unless it is indeed caused by the hot graphics card and not related to a failsafe mechanism. Do you've an expansion card perhaps? Share this post Link to post Share on other sites
ikon 438 Posted August 6, 2014 You didn't mention an add-in GPU previously. That could be rather critical to temperature control. Share this post Link to post Share on other sites
Royco 15 Posted August 6, 2014 You didn't mention an add-in GPU previously. That could be rather critical to temperature control. When I googled "noisy fan", most hits were related to the B120i controller and HDDs. I got distracted. Share this post Link to post Share on other sites
Royco 15 Posted August 7, 2014 (edited) For those who might be interested, I pulled the PCI card and now I get the 6% fanspeed under Ubuntu 14.04 with HPVSA. Here I post a temperature screengrab. TOP: With card (19% fan). Bottom: No card (6% fan). Update: I put back in the card: started with a 10% fanspeed, which slowly crept up to 19%. That seems hopeful.
