That was a very informative answer.

I know Barton Robinson at one point had used a ?MHz to MIPS ratio also,
and I couldn't remember what that was.

Thanks.

Larry,
the conversion rate for  Intel platforms to zSeries ranges from 3 MHz
per MIPS to 30 MHz per MIPS depending on how much data you are pushing
through the caches and out much serialization (context switches, locks,
etc.).
This is typically lower for the web servers and higher for the backend.
Because zSeries capacity is almost always a mixed workload capacity the
utilization peak and utilization variation on an interval by interval
basis comes into play.  This is because you have to configure each blade
for its peak, but you configure zSeries for the composite peak which is
almost always less or can be managed to be much less than the sum of the
peaks.
Because some workloads tend to saturate blades at lower utilization
than zSeries the composite utilization peak is usually quite low.

I know that this has been asked in many different ways, but has anyone
actually put together a comparison chart or list of CPU speeds for
zSeries, I32, I64, and other processors.

I have a department that wants to have a group of dedicated Blades
assigned to specific clients. We want to show a cost to Performance
ratio for purchasing blades and scaling a zSeries system.

The application uses Java, in the backend to run the queries and
retrieve the data, and Web servers to interface to a client and present
the results.
