Hi,
I have a dell power edge  2950 model 2 * quad-core with Intel® Xeon® 5400 and 64 GB RAM,

I need to use the same box for Web server as well as Aplication server.  From the IBM site i came to know that  Dell Power edge has 70 PVU per core.

Could anyone tell me how i need to determine the no of core required for 1 webserver and how many core required for application server.
I am planning to install VM ware esx os on the box.

I am plannig to install Red Hat Linux OS and above which to deploy WAS ND.

Thanks

Ashraf - The best way to idenfity the information you're looking for is to profile the application, or discuss it with the vendor (if applicable.)

That said, it's my personal opinion that resource allocation for what you're seeking is best discussed with your organization's ESX administrators.

There are a significant number of factors that come into play when virtualizing your application server platform.  These reange from subscription models, to resource allocation & activity, to the impacts of other applications on the same host.

So, unfortunately, there's not a simple sizing algorithm we can use to answer this question.  Every application is different and every ESX installation is different.

Something that works well in one environment may not  work at all in another...

Hi Ashraf,

  In addition to Erik's (i'm with him, there are not magic rules) here a different options to size your environment, maybe can help you sizing the environment:
 
 
  IBM Systems Workload Estimator
    www.ibm.com/systems/support/tools/estima...
    
  rPerf
      www.ibm.com/systems/power/hardware/notic...

  SPEC
      www.spec.org/benchmarks.html
      
  TPC

  Hope this helps,

@ Erik,
hi,
I checked with OEM vendor for sizing, he told to get the PVU details from IBM first , then come back.
Anyways thanks for your iput, le me work upon it..

@Gabriel - Thanks for the link. Let me check upon them.

Ashraf,
 
   Check this post of Erik's about PVU of WebSphere
   
   www.websphereusergroup.org/go/thread/vie...

  Take in mind that if you are planing to deploy in virtualized environment (ESX) you need to care about subcapacity.  If you don't take this in mind you a going to pay for the phisycal procesors of the ESX (8, 16, 32,....) and not for the virtual processors assigned to your virtual machine (1, 2, 3, 4).
