Opterons 72 times better than Itanic |
|
|
Sun has tried to factor in price, performance, rack space, and watts.
This seems like a good thing to do. By Sun's calculations their new
Opterons are 72 times better than HP's Itaniums:
http://www.sun.com/emrkt/itanic/
They made a metric they call SWaP, for Space, Watts, and Performance.
Where they say "relative price/performance" they really mean "relative
price/SWaP". |

That metric is just plain silly. It might make sense to evaluate cost by
using a weighted average, or the geometric mean, of initial purchase cost,
real-estate and power consumption, but *multiplying* them?
Are we sure that Sun's web site hasn't been spoofed?

Ya. It could be better. First we would want to know how long the
average server is used (maybe 3 years). Then estimating the cost for
rack space (looking at machine room costs or co-lo costs). Then power
costs, including airconditioning. So you could make an attempt at
"total cost of ownership" and do price/performance using this. Maybe
someone will do better. |

It could be absent, which would be better, right.
The world does not need another meaningless marketing metric. Not at all.
