Actually, I believe that he stated that he had an EMC array. When we were
testing them out, we had our best performance numbers by reducing buffers
from our typcal 600,000 or so (on large systems) down to 1,000. It was
found that the cache in the drive array actually performed better than the
database cache (surprised me, but that's why you should ALWAYS run your
own benchmarks rather than trusting to "common sense").
