We've been running a HyperScale media agent on HP reference hardware for about 14 months now. Last month we added two additional drives for added capacity and upgraded to HyperScale 1.5. I now have 8 large form factor drives on the front of each server which have a maximum capacity of 12 drives so I've still got room for another 50% increase in capacity.
My question is: Since adding the new drives and upgrading the version of HyperScale, I've had multiple outages due to high internal temperature faults. Each node has had this issue at various times, no two nodes have failed at the same time. During the day when no backups are running the fans used to run at 12% of maximum so we've tweaked the BIOS for increased cooling and now see the fans runing at 32% of maximum. I'm not sure what things are like when backups run as that's the middle of the night. Also, I've checked with my facilities people and all data center AC units are running normally and there's been no change to the temperature setting.
We're a HP shop and have several DL380 servers and none have ever had a shutdown due to heat in the 15 years I've been here (Disclaimer: As far as I know).
So my question is: For anyone else running HyperScale on HP reference hardware... did you notice any issues following the upgrade to HyperScale 1.5?
At this time my next step is to change the BIOS to run at max cooling where all fans run at 100% all the time. This is fine, I just thought I'd check to see if anyone else had any similar issues.
