What is SWaP and iGenCPU SWaP values

What is SWaP and iGenCPU SWaP values As you may have noticed, Sun created SWaP--the Space, Watts and Performance (SWaP) metric.SWaP components are :
  • Performance: Using industry-standard benchmarks or your own benchmark !

  • Space: Measuring the height of the server in rack units (RUs).

  • Power: Determining the watts consumed by the system, using data from actual benchmark runs or vendor site planning guides

The SWaP metric is calculated this way :

SWaP

I recently provided iGenCPU v2.1 benchmark results for various platforms (see previous entries). I did start with this benchmark as it is the absolute worst case for the T2000. Let see how it translates into SWaP numbers :

SWaP_Table

Or as expressed in a chart :

SWaP_iGenCPU21

So what is the message here ?

If you are running floating point intensive applications (the immense majority of commercial applications are not), and you need a small form factor, the AMD equipped V20Z/V40z or better the Galaxy line ( Sun Fire™ X4100 and Sun Fire™ X4200 ) are the right answer.

I hope I convinced you here that the SWaP metric was not designed to make the UltraSPARC-T1 a winner every time  but to provide a critical metric for modern datacenters !

In 2006, we will look at a second microbenchmark called iGenRAM , and then explore LDAP performance (iGenLDAP), database performance (iGenOLTP) and even web performance (iGenWEB).

I am leaving for Tahoe, so see you on the Heavenly slopes or next year on this forum...







Comments:

SWaP as described above is an absurd metric (even though I'm completely FOR using space and power consumption as parts of the metric); useless for anything but marketing wars. what's the supposed meaning of Space\*PowerConsumption ? Simple - but much more reasonable imho - formula would be Performance/(Price + c1\*Space + c2\*PowerConsumption) where constant c1 reflects cost of space and c2 - cost of electricity (including cooling) in a particular datacenter.

Sun fire x4100..
