E250 temperatures

[Joshua Boyd]

I just noticed that the thermal error light was lit on my e250 running
solaris 10.  A quick login, and prtdiag shows:
System Temperatures (Celsius):
------------------------------
      CPU0    64    WARNING
      CPU1    47
       MB0    41
       MB1    31
       PDB    35
      SCSI    29


Yet, the fans still aren't full speed:
Fan Bank :
----------

Bank      Speed     Status
         (0-255)        
----      -----     ------
 SYS       219        OK


What is the real danger region for the E250, and will the light turn off
on its own if the temp goes down?

Also, does anyone know any tricks to make it balance the thermal load
between the two CPUs better?

Any other tricks?  I would venture to say that the area where the E250
sits is still generally under 70 degrees.  The e250 is near the bottom
of a short rack that doesn't actually have all that much running in it.
Below the e250 is a smartups 1400.  The only things running above it are
a SS20, a GigE switch, and a FastE switch (the FC array, T1, and Compaq
DL360 are off).  On top of the rack is a Ultra 5, and a few feet away is
an Ultra 80, which doesn't seem to have the same sort of monitoring on
it.  I may have to get a remote device to monitor the area...

Also, does anyone know if 280rs happen to run cooler?

Concerning the CPUs: each cpu slot has it own temperature range.  The range
may be similar or dissimiliar.  The temperature range is dependent on the
CPU itself, the airflow over the CPU.  The closeness of power supplies, hard
drives, cards, etc. effect the acceptable temperature of any specific CPU.
All this to say, you can't balance the thermal load of a CPU in that vintage
Sun server.

>From my understanding the UPS unit generate heat that will effect the

If a device sits on top of the 250 (that is, no air gap), it may cause
heating issues.  (We once had a shorty rack with a v120 and a 19" switch
sitting on top of the server [no air gap but the switch was only half the
depth of the v120] and the v120 would crash every few days.  We moved the
v120 down 1U in the rack and the crashes stopped.]

I would suggest that you add fans to the rack if possible and provide air
gaps if feasible.

Too bad that they don't have a way to tell it to move work from one  
CPU to the other until they equalize in this way.

Well, I did adjust the rack to allow more space behind the rack  
(about 24" from the back of the rack to the wall) earlier.

And upon your advice, I moved the T1 off the top of the E250 to  
create a 1U gap between it and the SS20.  Although I wouldn't have  
called the top of the E250 (after I removed the T1) warm to the touch.

Tomorrow I will try raising the E250 to have a gap between it and the  
UPS, if I have time around work.  That will require completely  
tearing the rack apart.  I need a larger rack (and perhaps a  
dedicated air conditioner for the server area).

If you can, get either a PCI-powered fan or one that fits in a slot
blank but is powered by the 5V molex connector - either kind will
exhaust hot air out the back.  I am assuming you have already checked
for dust, and for perhaps a stray ribbon cable blocking needed airflow.

When I move it away from the UPS, I will certainly open it to vacuum  
out dust.  I did vacuum the machine out already this year though.

I can look at a PCI fan, but the machine had three big fans across  
the middle of the case (front to back middle), and a lot of vent  
holes over top of the PCI slots.

Too bad that they don't have a way to tell it to move work from one CPU to
the other until they equalize in this way.


There commands, IIRC, to associate certain processes to specific CPUs.
Unfortunately, we never used that outside of class, that is, in the real
world.

If you have a service contract you Sun support vendor can find out if this
is possible.  (Maybe the list members know also and will fill-in this [and
any other] blank.)

[stephen price]

we just had to replace 2 of 3 fans in an older e250 in
the data center.

both of the failed fans sounded magnificient as
screeches & metallic howls reverberated around the
otherwise noisy room!

keep a close eye for what appears to be at least one
imminent fan failure (hope not) in your box.

According to the owners manual, the light comes on if any of the chip
sensors hit 60c or if the ambiant sensors hit 53c.  Shut down occurs
when a chip hits 65c.

I am using one PSU and 6 disks.  And they aren't particularly cool disks
either.  

Maybe I should try swapping 3 or them for cooler ones.

My machine mostly sits idle.  It has close to 1.75 gigs of ram.  It runs
1 zone.  It has dual 300 CPUs instead of dual 400s.

It feels to me like the middle fan puts out more air then the side
fans.  The middle one goes over the CPUs, one side fan covers the RAM,
and the remaining side fan covers the PCI cards (1 GigE card, and 1 dead
FC card.  I should have removed the FC card, but I didn't think about it
until I was connecting it back into the rack.
 
> what kind of computational load are you running?

Generally very little.  This machine doesn't serve anything publicly.
It just serves files (which means it doesn't do much of that when my
wife and I aren't home), serves CVS (that I use from work sometimes, but
not heavily), and that is it on a day to day basis.

It is a rack mounted configuration.  I would assume I have the proper
side panels for rack mounting.

It was probably the dust in the fan tray.  There was still a lot of
airflow, but after cleaning the fans (which I hadn't previously realized
were removable), there is still more air moving out the back of the box.

At this point, my fan is still running faster than yours, but the CPUs
are slightly cooler than yours.  prstat shows a load of 0.03 on the
machine.

so i show a slower fan and lower temperatures.   i've been worried that
my room temperature is too high at around 75-degrees F, but have never
gotten a temp warning light in the five years this machine has been running.

this machine is not mounted in a rack, just sitting on the floor, in the
stand-up position and has another E250 on the top of it.

i am running both power supplies and 3 disk drives.

the two CPUs are the same...are your CPUs different?   this machine
is running Solaris 10 with 12 zones and in some of the zones there
are 20 virtual hosts of apache, and some heavy usage in perl scripts
for bulletin board system called Discus, so the perfmeter frequently
shows both CPUs maxed out and the load average up to ten so the
machine isn't just sitting idle.

when you have the machine apart, i'd check that all three fans are
putting out the same volume of air, feeling the flow with your hand
should be adequate for that.  i could imagine that if one fan were
running slower then the lower airflow could make a difference on the
parts cooled by it.

this is cooler than the external temperature that my machine is running
in.

is the e250 laying down in the rack-mount orientation or standing up in the
"normal" orientation shown in the product pictures?   and assuming that
you have the side panels on the e250 which make the airflow go the way
intended by the design.

in feeling the e250 there is no warmth from anyside of the side panels,
the airflow keeps the case absolutely at room temperature.   so i can't
imagine that any gear either above or below would affect its temperature
in any measureable way.

I can't wait to make this system the new ohno.mrbill.net.
I've had it for a year and a half now, and firmware issues (fixed
in development, but not publicly released just yet) have

    Initially I wanted to post something really full of invective
and expletive, but somehow can't.  Hell, I can't even post a "prtdiag"
output 'cause my front-line SPARC doesn't have it.  Some dmesg output
will have to do....

Until fairly recently (months), the primary DNS server for
rodents.montreal.qc.ca was a Sun-3/60.  (The primary reason for the
switch was that I got a UPS and wanted to put the DNS sever on it, and
the -3/60 sucks down a lot more power than the DNARD I moved it to.)

How did you end up with a DNARD?

I wish I had a bit more variety in action.  Maybe I'll rack mount an  
EFIKA someday.

Indeed.  I'd love to have a DNARD.  It's too bad they're so hard to
find.  I'd actually love to have three or four.

It has to do with the network LOM dropping off the network or suddenly
no longer listening to the SSH port.  I don't want to deploy the machine
if I'm not able to get to a serial console on it for reboots, patching,
remote maintenance, etc.

The machine is physically in Austin, and I'm 150 miles away in Houston,
so it's not like I could just drive over to the datacenter.

I've been working with engineers at Sun, and they've identified a bug,
done a fix, and it will be in the next revision of firmware for the
machine.

I thought prtdiag was in Solaris 2.5 - look in
/usr/platform/<platform>/sbin/.

We still have an Ultra 2 as a DNS/NIS server on one of our subnets.

And until a couple of years ago we had a SS2 running 2.6 with 64M RAM
as a license server. 8-)  They're good machines.

Not on sun4c.
