PA RISC to Itanium

We are looking at upgrading to an RX6000 type hardware from RP7400.
We have a number of applications, whose vendors state they are not supported on itanium. I have read that a product calle Aries will run on the itanium and handle the PA RISC binaries.
The OS may be 11.23 or above.
Questions:
1. Have any of you done this successfully?
2. Were there any gotchas?
3. Is Aries an -
a. Add on?
b. Billable for support?

Thanks for any and all input.

Re: PA RISC to Itanium

1 & 2) I have heard lots of people say that things will run just fine via ARIES. I don't have any RX boxes so I don't know.

3 A & B) ARIES is installed with the OS. It is not an addon nor is there any additional support. It is a standard feature.

Re: PA RISC to Itanium

Hi Dave:

ARIES applies to Itanium servers and 11.23 as far as supported release go. See:

http://docs.hp.com/en/B3921-60631/ARIES.5.html

11.23 and 11.31 on Itanium servers will have ARIES support.

Re: PA RISC to Itanium

All questions answered. I did have the doc referenced, just wanted some experienced input, which I received.

Thanks again.

Re: PA RISC to Itanium

The only "gotcha" with ARIES may be performance although I rather doubt it going from an old rp7400.

Typically the cpu bound portions of code run about 1/2 to 1/3 as fast under emulation as compared to native code. The vast majority of UNIX code is i/o bound so that the actual performance impact may be very minimal. In fact, even under emulation, newer Itanium boxes can outperform the older PA-RISC boxes.
If it ain't broke, I can fix that.

Re: PA RISC to Itanium

Which vendors are not offering Itanium versions? Perhaps something can be done there...

Re: PA RISC to Itanium

A. Clay-
That was a great question for me to put to the reseller. With the increase we will see in the TPM, we should be able to more than offset the overhead of 30-50%.

Rick -
The application is supported by a company named JDA. I think the availability of Aries may be leading some vendors to feel they do not need to address the PA RISC binaries on Itanium.

The money is there for a compelling argument on the upgrade. We've had the RP7400's for 7 years. They are still performing quite well, but the HP business partner has made if difficult, due to ROI, NOT to move to Itanium. We have thoroughly researched compatability with all peripherals as well.


Thanks for the input.
