Re: HP9000 N4000 Server upgrading

Thanks for that. I think they want to bigger.

But does anybody still know the TPM-C value for a PA-8500 440Mhz CPU. I have done a document that uses this value to work out the total tpm-c value for all 8 CPU's. Based on this we will be able to spec another bigger box. If what I have is correct (tpm-c of around 2443), then I have calculated that the 8 CPU's gives around 16758. (SMP of .9). This means that in order for our application to run comfortably at below 30% load on this new hardware, I need a system capable of delivering 44130 tpm-c's. But it is imperrative that I know what the initial value is for the PA-8500.

Your urgent help please...

Clark,

the figures I have state 49.308 tpmC for a 8 processor N4000-44

Re: HP9000 N4000 Server upgrading

Thanks again for pointing me in the right direction.

Our application uses Tux and Oracle (a lot less tpmC's than the Sybase equivelent) So I interpollated the HP9000 V2500 with 32xPA8500/Oracle 815/Tux. This gives a value of 92,833. SO I divided this by 32 and multiplied it by the SMP value (10%), this gives 3191 per CPU. Even though its a different server, I think it should be close enough.
:)
Thank for your help...

Clark,

if you consider rx#### (Itanium) machines, you should be aware that you need to upgrade to Oracle 9 before the transition.

Consider your apps dependendies as well.
