This was a fun read.
Jerry Springer would love this thread! :-)
Kebby - a 500W processor - you should know no such processor exists - it sure as heck couldn't be air cooled! Geesh...must I post a Paris picture again! You and Mr. Halko must have gotten hammered a few times courtesy of a Sun credit card...
Neither of these systems is going to land on a floor - though I know I'll see a lot more 595s than 12-node T2+ systems around - IBM sells a lot of 595s (according to them and IDC etc.) because its a general purpose machine. The fact that a little over a year ago IBM needed as many storage units and spindles to produce their result is an impressive statement with respect to the 595s I/O capabilities. Heck, even HDS used a 595 to produce a SPC disk benchmark! Side note - HP had to show they used a 595 too when they used the HDS benchmark result to show off their rebadge storage box - what a hoot! :-)
Halko - calling Sun an innovator with respect to Niagara - do some fact checking - Sun bought Afara to get Niagara technology - its no Sun innovation!
Were flash storage in the IBM kit bag when the 595 result was published, I suspect it would have been used for the obvious price/performance benefits Sun/Oracle showed.
This benchmark, like many others shows me that core for core, which is how I pay for all my database software (perpetual licenses only please!) T2+ can't keep up with POWER6. Small caches, low memory bandwidth per core - things might get better with DDR3 and extra memory controllers etc etc...down the road.
Just look at POWER7 for a timely 8-core processor. Everything falls nicely into place - faster memory, faster busses, bigger caches, on chip L3 via EDRAM - no question Afara was a little ahead of its time and Sun made a good purchase, but Sun an innovator - not in server hardware...
