Re: IBM i 7.4 and IBM i Portfolio give strong foundation for continuing innovation

You mention HANA - do you mean to speak about that relative to IBM i?

It'd be a question to ask, but I did not see that Db2 Mirror for i is 
duplicating memory synchronously. Maybe you aren't saying that, but it 
is confusing to me.

I am not too concerned about R0CE - it's been over 3 years that IBM are 
working on this new LPP, time enough to work things out.

Cheers
Vern
