Are they beasts or not too bad? How are they vs an Ultra 10?

Thanx!

They're pretty noisy while they're booting, but once Solaris is up
and running, they're quiet. I've no idea how they compare to an
Ultra 10 (I don't have one), but my SB 1000 is significantly quieter
than my Ultra 60--and the latter has the noise reduction kit fitted!

There are different opinions ranging from very loud to not worse then
my PC.
I've seen a report in this newsgroup from somebody who spend a weekend
to put rubber isolation inside the Blade to reduce the sound.

I've written a report about my Ultra 10 and how i made it silent (~18
db now - something you really can' t hear). Unforunately it's written
in german:

I found the Ultra 10 to be much to noisy for a workstation. The Sun
Specs give allmost the same technical bell numbers. So i guess it will
be loud if you are sensitive to noise.

One more problem is that the Blade 1000/2000 do not contain normal
hardware parts, so it's almost impossible to create your own noise
reduction kit. And i don't know if there is one from Sun for the Blade
(i only heard about this option for Ultra 80/Ultra 60).

As I don't own an Ultra 10 I can only talk about my Blade 2000.
The two main sources of noise are:
1. Two big (119mm x 119mm x 38mm) fans
2. The disc(s)

Both fans are temperature controlled but they produce some air flow
noise even when the machine is idle.
Both produce enough noise such that the disc is no problem ;-)

I have replaced one of the fans by a low noise Papst fan. After this
I was able to hear the original SUN 72G disc (MAN3735F) and thus
replaced it by a Seagate ST373207FC.
Now I can only hear the disc during reads or writes.

After all I have to conclude that my machine is louder than my PCs,
but it is bearable.

As far as I know, the kit is only for the Ultra 60 - there is nothing
from Sun to reduce the noise of an Ultra 80. I might be wrong, but don't
think so.

I've got such a kit in a Ultra 60 that I rarely use, so if it was
possible I'd move the kit to my UItra 80 which runs 24/7/365. That said,
the Ultra 80 is pretty well packed, so I doubt it is possible for me to
reduce the cooling much.

The Blade 1000 has large "controlled" fans and the U10 small and
stupid ones.
So unless you run into a Solaris problem they should be
pretty good. The Blade 1000 is a beast until booted.

The U10 has a weird high pitched noise while the Blade 1000 is
more of a breezer. Note though, if you have very old 10k disks in
your Blade 1000 it might be worhhwhile to upgrade them.
The old ones might produce more noise.

For me the Blade 1000 is much easier to my ears.

Don't know about the Ultra 10...
But I have one Ultra 5 and one Blade 2000, and the Blade 2000 is a lot
quieter than the Ultra 5 is.
The Ultra 5 was really noisy with the default fan and the default hdd.
I changed the fan's too Papst fan's, much better =).
I also changed the hdd to a newer and more quiet Seagate Barracuda disk.

But you can't change the fans in the Blade 1000/2000 though it's not
"PC-standard" fans. Although you accually don't have to change the fans,
they are controlled and quiet.

The only time the Blade 2000 is really noisy is during boot and shutdown,
don't know why...

If i have a huge CPU bound task like a large compile job where
utilization is near 100%.
How long do the fans need to go to full speed ?

My iMac G5 is going from okay to extremely noise just after a few
seconds 100% CPU useage. This means during each compile and this on-off
is much more worse then a constant mid level noise. I can't tell you
how much i hate this machine.

Never. I've never seen the fans go beyond 40%, even with both CPUs
going at full blast for an hour. Ambient temperature is 24ºC, the
machine is a Blade 2000 with two 900MHz Cu CPUs compiling Firefox
1.5.0.3 (from prtdiag -v):

---------------------------------------------
Location Sensor Status Speed
---------------------------------------------
+stem-fan-slot system-fan okay 31%
+/cpu-fan-slot cpu-fan okay 34%
+r-supply-slot power-supply okay 100%

Temperature sensors:

I agree - I had a laptop that did exactly the same thing and it was far
more disrupting than a constant noise. I was very pleased when I could
replace it with an Acer Ferrari 4000 which has a constant fan.

My Blade 2000 is far quieter than a cheap Athlon 2000+ based Linux PC
that shares my desk, even with 2 10,000 rpm FC-AL disk drives.

I forgot to say that the PSU fan is always at 100%, even though the UPS
(a Liebert PowerSure 1400) shows only 350VA being used (it used to be
308VA with the Elite3D, the recently acquired XVR-1000 pushed it up to
350VA). My 18.1" Sun LCD is also connected to the UPS, so all-in-all
the power consumption is pretty reasonable.
