Well,that just about means your 2Gb over and above 4Gb will NEVER be used,no matter how many processes you throw at it.

It's not in use because you have no applications anywhere that will use it. It's like the old "expanded memory" thing: if the program is not written to use it, it don't get used. Nothing to do with W2KS: it just provides the facility and stays out of it.

No it won't. Or else there is something very weird going on with M$'s and Oracle's information. Throw in 100 instances and it *still* won't be used. W2KS simply won't use that memory. It will give it to any single program that *requests* it, but if you don't have the AWE extension turned on in *each* Oracle instance, they won't touch that memory. Nor will anything else that is not written specifically to use it.

It is NOT, I repeat, NOT, part of the virtual or real memory linear addressable space for use by all processes. No matter what DELL might say about it.

?????
If you "use" them, they are used on a 1Gb window by Oracle alone, and then again only for database buffers. That means they are outside of the influence of the paging daemon. W2KS won't touch that memory with a ten foot pole: it can't, its real addressable space stops at 4Gb and that's it.

OK, that's fine.
