We do not support Oracle Exadata\Exalogic servers in our products(CA Capacity Command Center, Capacity Manager and Performance Optimizer).
The Oracle Exadata Database Machine uses commercial processors, but it only runs a customized version of Oracle. Part of what provides its very high performance is LOTS of flash memory cache. We suspect that if you took performance measurements from your current Oracle system and move that workload to the Oracle Exadata Database Machine, that you would get inconsistent response times (and so the same would occur with the model).
Oracle Exalogic and Exadata are very similar, with the major difference being that Exadata is optimized for running the Oracle Database whereas Exalogic is optimized for running Oracle middleware and applications.
As said already, these database machines do not run typical application code. For example, here are some of the things that Oracle says about the Exadata X4-2:
- Up to 192 CPU cores
- Up to 168 CPU cores dedicated to SQL processing in storage
We feel that because of the flash memory cache, the response times are going to be quite different. We expect that the CPU consumption will probably be in the ballpark, but because of the Oracle customization for the Oracle Exadata\Exalogic Database Machine, we don't know how close it will be. Thus we are very reluctant to put a model out there that we're not confident will produce useful, reliable and understandable results
The processors cannot be characterized in terms of performance, (What are the other 24 cores doing, is a question)
CCC\CM\PO supports benchmark in terms of SPECint2006.
But is performance relevant? Can’t we get a model that gives us moderately accurate CPU utilization figures?
I had a similar question, but Ken Zink said that we would not be able to provide any hardware models for Oracle Exadata servers and not any other models can be used for the reasons aforesaid.
We currently have 2 models available for Oracle Exalogic servers
Oracle Exalogic Blade X2-2 3067MHz Xeon X5675
Oracle Exalogic X2-2 3067MHz Xeon X5675
I will check more on hardware models for Exalogic servers in future and update this thread..
