Re: Number of CPUs vs. Speed of CPUs

I may be blowing smoke out my back side but here is my opinion: Fewer and Faster

Reasons:

I think Oracle has started to license by cpu instead of the power units thing. So if it is cpu number, then fewer and faster is cheaper.

Oracle also "was" and may still be licensing based on maximum box capacity. So if you have 2 machines that are both 4 way (4 cpu's installed), but machine one max'es at a 4 way and the second machine max'es at a 10 way, you pay more for each license on the 10 way than the 4 way even thought the 10 way is using just 4 cpu's. Doesn't make much sense to me but that's how pricing worked last fall.

>From an OS level, when cpu's are added it's a diminishing return issue. So
historically a "4 x 800mhz" is faster than a "8 x 400mhz".

We are in the process of sizing a new server for multiple Oracle instances. What factors are useful as input in determining how many CPUs and the relative speed of them? For example, do we want fewer, faster CPUs or do we
want more, slower CPUs? Are there any good guidelines to determine what the
number of CPUs should be?

Thanks in advance -
Lisa
