They are awfully nice little boxes; but there is one other flaw - there's
a bug in Solaris 8 with respect to clock management on the X1 and Blade
boxes. Even with (x)ntpd running, the system clock will occasionally (on
the order of once or twice a day) jump by 20 or more seconds out of sync;
and stay that way for a random time period. (One company I work with has
a farm of 30 X1s and a distributed app where time synconization is critical.
Their boxes usually stay out of sync for about 5 to 20 minutes before ntpd
slams them back where they belong.)
(No, it isn't a configuration problem or lack of system patch. Sun are
apparently aware of the problem and working on a patch upgrade.)
Oh, and you have to make sure your X1 farm is in a properly air-conditioned
environment; otherwise they tend to start to overheat and automatically shut
themselves down. (I would expect the same requirement of any equivalently
powerful 1U box...)
