Re: ML 350 g5 seems to overheat
Let's wait some other day before lifting the "red alert", but, adding Holger's trouble to it, the conclusion looks one: Achille's heel of this ML 350 g5 server is the power supply!
We had already a minor problem with it; a few days after buying the server October 2008 the power supply became extremely noisy, like an airplane and we asked for a spare part from HP. That's the reason we had a 2nd supply in stock. Now the old and noisy power supply is in place and up to now not noisy and not hot.
The question is: is there a new revised power supply for these servers?

Re: ML 350 g5 seems to overheat
There's an old issue on PSU's, and it could be the ML350 G5 is affected.

Re: ML 350 g5 seems to overheat
A week after changing the PSU absolutely no problem with the server. No doubt the PSU was the cause of the trouble.
But touching the PSU I feel it still hot, not so hot as the previuous, but the PSU of our new ML 350 g6 is quite fresh.
Now, is it better to have a new PSU from HP (after 2 1/2 years should they give it free?).
I searched the HP forums and found a lot of similar troubles with ML350 g5 power supplies: sudden noise, server arrest ... e.g. http://h30499.www3.hp.com/t5/ProLiant-Servers-ML-DL-SL/NOISY-FAN-on-ML350-G5/m-p/4332257#M86822
I've still the doubt: did HP produce a more reliable PSU for the g5? Or is it just a matter of firmware?

Re: ML 350 g5 seems to overheat
just to keep you informed; finally my server is back (after 8 weeks repair).
the heat problem is for sure a problem of the power supply! in the returned unit they exchanged finally 8 HDD's; DVD rom, Tape player, cable converter, sata cable, redundant fan, sata HD cage, psp backplane and the PSP itself.
on the way to this result they destroyed 4 additional HDD's, 2 backplanes, 2 fans, 2 SPS and another backplane...
YES there is a 3 years warranty and yes, i'm lucky, its still due for 4 month...
So Paolo you should really give your server to HP and they should run full diagnostic, and exchange everything under doubt.
I hope my server will make it; if yes, by by guys, this is my last mail. Thanks again for your support and compassion.

Paolo, I don't know the numbers, but power effincecy is improving, even though performance and workload is increased.

Re: ML 350 g5 seems to overheat
Yesterday night both server g5 and g6 went down together!
From the iLO 2 log it results a "Server power removed" preceded by a "iLO 2 network link down" (this is something new and at the same time 22:18, what does it mean?); a few hours before a "SSH login failure from:" on both server from the same IP.
Now the only thing I can guess is a hacker attack. Or have You another explanation?
Following is the Log of the old server (the other is similar, but power removed is just at 22:18)

Re: ML 350 g5 seems to overheat
It was just a power problem in our school! Very simple, no hacker.
The SSH login failure was just a failure after all!!
Beg your pardon for the useless post!
And I think I can really close the thread now.
