Re: U30, "Sun Noise Reduction Kit"; where to find (buy)?

Have you inquired of the business that sold you the U30? If they don't
have it in stock, they should be able to order it.
Failing that, call Sun and ask where you can find a dealer who stocks
the kit or a dealer who will order one for you.

Also, plug in the part number (595-5364) to google, and you'll find a lot
of vendors who list it. Give some of them a call and see if they can
actually get you one.
However, I would expect that your biggest source of noise is the hard
drive(s). Old SCSI drives tend to keep going forever, but get noisier
and noisier with time. Try powering down and pulling the drives, then see
how bad the noise is when you power it up.
Also, some standard things: Make sure all of the screws in the case are
tightened up (most of the screws are for drive/card mounting, but look
around in there) and that the side panel is on properly.
Good luck. You'll never get an U30/U60 to be as quiet as a modern PC,
but they can be liveable. (Says the guy with a loaded U60 and 6-disk
multipack in the computer room :-).

Having purchased one of these for an Ultra 60, which is very similar to an Ultra
30, I would suggest you do not bother wasting your money. The benefit was very
small. (I have owned both a U30 and U60 in the past, and can tell you the noise
from them is about the same).
Up until a few weeks ago, I had two Ultra 60. One had its Ethernet connector
destroyed by lightning but had the noise reduction kit installed. The other
Ultra 60 was in good shape, but did not have the noise reduction kit.
I decided to scrap the Ultra 60 with the blown motherboard, as it was not worth
the hassle of repairing. I did contemplate removing the noise reduction kit and
fitting it in the other Ultra 60. In the end, I decided it was more hassle to
remove and refit! So I scrapped the U60, complete with the noise reduction kit.
That kit really is next to useless. You will find others say the same if you
hunt around.
In contrast, machines like the Blade 2000 and Ultra 27 sound like rocket engines
when they start up, but quieten down dramatically when the thermal control
systems get working.

But the Ultra-45 is a different story, unfortunately. I used it to replace
my Sun Blade 2000 but I quickly got a Sun Ray and moved it to the lab.

I've never owned an Ultra 45.
I like the Ultra 27 - it is a lot quieter than the Blade 2000, and in the
configurations I have for the two machines, the U27 uses about a third of the
power of the Blade 2000. (The Blade 2000 has a SunPCi card, but the Ultra 27
uses VirtualBox, which clearly is one reason for lower power consumption).
But I seriously would not waste much money on a U30 noise kit, as I doubt it
will make much difference.

Everyone in our group has an Ultra-45. Three of the ones in our office
are remarkably quiet, and one is fairly noisy. I think that some of the
fan control routines were modified in the OBP updates. One of these days
we'll get the noisy one upgraded to see if it makes a difference.
My Ultra-45 is at least as quiet as a (booted) Blade 2000.

My Ultra-45 is very quiet now after I replaced some of the stock fans with
random pc fans that I got from the local pc store. Only paid about 20 EUR
for the replacement quiet fans and now even with 8 disks installed the
system runs cool and quiet. I also have one extra disk backplane on the
chassis to get that 8TB zfs/nfs service out of the chassis with SATA disks.

Did you install the extra backplane yourself? I never saw that when I
bought mine,only for the U40 if I recall right!

Yes I installed the upper backplane myself. Bought one LSI SAS HBA to
drive it and soldered the wires myself. Ultra-40 and Ultra-45 share the
same chassis. There was even power available to the upper disk backplane
by default.

Yes. I would have wanted it to have two processors but one was not
available.

Nice, really nice.
Maybe you can get a second CPU on ebay now, it is a big difference going
from single CPU to two less "lockups" smother system and twice the memory.
