No, I don't think it does confuse the issue any further than it is already. That was, in fact, precisely the point!

The original poster wrote, "yes, and i think that ASM could be easy for migration to another platform. "

Define "platform" in that sentence for me please? You seem to think it means "storage architecture". I took it to mean "OS", because that is typically what people mean when they start talking about "migration" and "platforms".

But see... regardless of who has mind-read the OP correctly, instead of just having a go at Bob for his ignorance levels, it pays to be clear on what ALL participants in the thread mean by their choice of terminology.

It's good, anyway, to have you concede that ASM will play no part in easing the transition from Windows to Solaris. Which is (I think) what Bob was getting at.

ASM gives you storage independence, obviously. That wasn't (I think) the point about 'easing migration' that was originally being made, however. Received on Mon Sep 24 2007 - 13:21:31 CDT
