Hi

I've just won an auction for a cool little machine based on the
Tadpole 3200 upgrade motherboard:
http://www.linuxco.org/Tadpole3200_hires.pdf

This is the same form factor as the venerable Ultra 2 :-), but takes
up to 4GB of memory, and up to 4 CPUs. The CPUs can be up to 480 Mhz
with the 4MB cache. This is going to replace a U2 with dul 400Mhz/2MB
cache CPUs.

I am wondering where I can find information on the power usage of the
various 4MB cache USparc II CPUs - 360Mhz, 400Mhz, 450Mhz and 480Mhz.
Not that I actually expect to find any 480Mhz ones.... :-)

Cheers, Liam

That sounds similar(ish) to an Ultra 80. I've never measured the power
consumption, but judging by the heat mine produces, it is not
insignificant.

Here's a couple, quoting from Sun PDF data sheets. You should be able to
find the originals somewhere - I did once - plus for the other processors.

Module Power Consumption
This UltraSPARC-II CPU module requires two supply voltages. The required
voltages (provided to the module) for the VDD and VDD_CORE, are
respectively 3.30V and 2.6V. The estimated maximum power consumption of
the UltraSPARC-II, 400 MHz CPU, 2.0 Mbyte E-cache module,
(SME5222AUPA-400) is 57.5 watts at 400 MHz. The estimated maximum power
consumption includes the CPU, the SRAMs, the clock logic and the 8 watts
consumed by the DC-DC regulator.

Theorem : quad ultra 20, ultra 2, ultra 80, blade 1000/2000 are not
worth switching on given computation/watt metrics.

Thoughts?

ITYM quad SPARCstation 20.

If you don't switch it on, how will you see the SB1K's glogo? :-)
More seriously, the SS20 doesn't draw that much power, so it might
be OK as a small DNS server or something. (That said, mine remains
powered down at present, mostly because it's so slow and because it
can't run S10).

Owns: SS2s, SS20, Ultra 1s, Ultra 60, SB1000, and Ultra 20. Oh, and
a 3/80 (which hasn't been powered on for aeons)!

Ouch. I just tonight rolled my new toy into the home computer space. An
E450 with 4 x 450MHz CPUs and 4GB of RAM.

It will be running Debian Linux. I plan to stick a 4.5GB drive in as /boot
(with the extra spaced used to back up critical config files). a 9GB drive
as /. And software RAID 5 several 36GB drives to mount as /home (with
/var/www soft linked to /home/www).

It's going to be the "everything box" for the house. Serving up my
personal web pages. Playing mail server for my domains. Serving up media
for my networked media player (the reason for the big stack of drives).

It will be headless. Not running Xorg or anything super CPU intensive so
the power per CPU should be well below maximum (crossing fingers). I may
plug it into a Kill-a-Watt power meter for a few days before I start
actively working with it to see what it draws (and how loud it us) at idle.

I still need to find drives and another couple of SCA backplanes before I
do too much installing anyway.

Sounds like an ideal candidate for Solaris 10/Express and ZFS. You
should get much better performance form raidz than from other software
RAID options.

You might want to think twice about the Linux, those 450's are getting so
old now that I haven't seen a whole lot of discussions lately but it seems
to be a reoccuring problem with the fans running full speed.

I guess there is something with the Solaris to control the fan speed "as
needed" that is missing from Linux distros. Thus the fans turn on full speed
and stay there, and in the E450, there is a lot of them.

So unless you were planning on putting the machine in a remote location
(like a basement), you, the machine and the house aren't going to live in
peace and harmony.

I'd stick with S10 for that thing.

Why would you run Linux on an E450? Solaris would be a much better
choice!

IF you used Solairs, you could use ZFS' raidz for better performance
and resiliance for those disks.

It's not a quiet a machine, and sucks a lot of power even when its
quiescent. Probably not the sort of thing you'd want on 24/7 in a
house! My E220R is only just tolerable...

You might want to think twice about the box also.

Buy a new PC with appropriate hardware for fileserving.

The powersavings alone will pay for it in a year.
