They were also surprisingly slow. Without any hyperbole, you could
almost certainly replace an entire rack of ten year old 1U servers
with a single 1U server today for a very reasonable cost and see
performance that's at least equal, with a fraction of the power draw
(and associated ongoing costs).
easily, and even with the overhead of virtualization, have each of them
be far faster.
I forcefully retired and virtualized any and all remaining 'netburst'
(P4) architecture machines in my lab onto a 12 core nethalem based box
and each one is way faster even when they are all being blasted at
once. SAS rather than SCSI is more robust and reliable (10 year old
SCSI cables are fun sources of random glitches).
