Tony, <I thought they had blown off USII and were only fixing it on USIII boxes.>

I thought their USIII actually had ECC on their caches.

Tony - Re: "Problem with the bolt on approach they selected is that, if you get a particle hit that causes a soft error, it probably takes a relatively long time to go over to the mirror copy and run with it. During that interim, it's possible for other things to go wrong and really take them down an ugly path. Maybe something like swerving to avoid an animal in the road, but requiring someone in the back seat to do it. "

Sun is obviously NOT having great success with their mirrored cache approach.
