Re: Domino cluster on OS400 and Windows?

[Chris Whisonant <Chris.Whisonant@xxxxxxxxxxxxx>]

Thanks for the info Walter! The great thing about Domino clustering is 
that is is platform-independent. The clustering is done by Domino so the 
hardware and OS are basically irrelevant other than meeting your system 
requirements.
