Module Power Consumption
This UltraSPARC-II 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, 450 MHz CPU module, 4 Mbyte E-cache (SME5224AUPA-450)
is 69.20 watts at 450 MHz[1]. The estimated maximum power consumption
includes the CPU, the SRAMs, the clock logic and the 8 watts consumed by
the DC-DC regulator.


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).

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.
