Comparison of performance between PARISC and Integrity

I'm looking for some balanced data to show a comparison of performance between PARISC and Integrity servers.

Does anybody have any information?

Shalom,

PA-RISC development has been done for a while. Sales stop the end of 2008.

In tests I've run doing the same work on both systems, I've seen Integrity systems run circes around PA-RISC, smiliar lines, entry level versus entry level?

Re: Comparison of performance between PARISC and Integrity

Bear in mind that there is no possible answer for your question except "it depends".
For example, if you have a largely CPU bound application then Integrity is going to smoke PA-RISC but the vast majority of UNIX applications tend to be i/o bound; if only 5% of the total bottleneck is CPU then even if Integrity runs 10X faster than PA-RISC then the overall performance differences are going to be very small. The good news is that the i/o channels on Integrity are better as well but if the rate-limiting step is the external disk array then you are still bound by its performance.

I'm telling you this so that you don't make unrealistic assumptions about the abilities of a new box that in reality only performs marginally better than the box it replaced because the box itself wasn't the major bottleneck. I've seen this happen many, many times and often what was said and what management heard were quite different things.

Know your applications and your environment so that your expectations match reality.
If it ain't broke, I can fix that.

Re: Comparison of performance between PARISC and Integrity

Steven & Clay;

Thanks for the input from both of you. As Clay mentioned we are not CPU limited, so I don't have high expectations of VAST system performance increases in an Integrity environment. I would like to know if an Integrity purchase is more than clock speed.
I will look at the links Steven sent before I make any final comments on this thread.

Re: Comparison of performance between PARISC and Integrity

Apart from the CPU some servers are very similar, for example the rx8640 and rp8440.

http://h18000.www1.hp.com/products/quickspecs/12697_div/12697_div.HTML

But the Integrity has much more features - like virtualization (HP virtual machines) and multi OS support (HP-UX, Windows, Linux, VMS) - even at the same time.

Hope this helps!

Torsten.

Re: Comparison of performance between PARISC and Integrity

Torsten,

I am more interested in seeing a comparison of performance benchmarks. The links that Steven provided show the information I was hoping to see.
