Virtualisation

[Mick_chair]

I have been asked to think about replacing 60 PA Risc machines with Itanium machines.
Virtualisation would be key for this. I would probably use SAN + something like a couple of rx8640s but am constrained by the number of fibre connections I can have . As in inderstand it each Vpar would need its own fiber adapter ?
Is there another way of achieving this buy virtualy / sharing HBA's between partitions ?

Using vPars, you can only assign at the physical HBA level to a vPar. In other words, one HBA can belong to at MOST one vPar.
The granularity for vPar's is:
per physical core, per HBA.
It depends how many vPars you woul dwish to build, and how many cell boards and I/O chassis there would be


If you need to go "lower " than that, you could consider HP Integrity Virtual Machines .

Thanks for the reply. VM's are definately the way to go. Just got to work out how many I can get on a fully loaded 8640

that is going to depend entirely upon how many cores you have, how much physical memory you have etc.

And then choose the relevant version's manual, and this should help you to determine your configuration needs
