yeah, I don't really understand how the solaris idle page scrubbing

yeah, I don't really understand how the solaris idle page scrubbing
interacts with whatever. scrubbing's a hardware feature for AMD. I

The OS is not involved with the ECC functionality of the hardware

That's interesting - I didn't run into that in the background search.
I suspect that some motherboards just accept the ECC memory bit

Thanks for replying! I did look into that. The AMD design was my second choice.
It was :
AMD Athlon II X2 240e (to get low power; the dual core and lack of L3 help
there)
ASUS motherboard (see considerations below)
Cheap VGA? LAN card? This is the mire that ultimately bogged down this one.

I would suggest a CPU with small L2 cache, as L2 cache will not help a file
server. This allows you use AMD's new 45W cpu. And 64 bit. 2-4 cores.
And use raidz2.
