Yes and no... You can do local caching or server side caching.  Depending of
the workload of the workstation/server you may be better off have a local
disk for client side caching, otherwise you may be pushing allow of traffic
across the wire only to put it back on the wire.  So, no, you don't need a
local disk but if you have one even better.  Keep in mind this is for
Standard (shared mode) and does not apply for vdisks in private mode.

Isn't this what Ardence does? You don't need local disk for an Ardence
solution. I'm not 100% across this, and I haven't tried it yet, but this is
what all the doco says.

That begs the question if perhaps can actually setup WIN2K3 to run purely
from RAM and speed up all that caching and thrashing stuff!!

Well I'll have a go at answering it - I would speculate, largely, that
it's because from the design stage it is a multi-purpose OS, that as
well as providing or catering for different types of workmix, always
*attempts* to be responsive for new processes. Hence, the pre-emptive
paging.

This was a reasonable change from OSs that only ever used virtual memory
when they'd run out of physical memory.

And it's (the OS) nature is such that it's not lent towards performance
customisation. By that I mean that in older times, when OSs were more
bespokely tuned to eek out the best performance, this required a
reasonable degree of expertise and knowledge. Whilst there may be some
tweaks and settings that can be applied to Windows servers, these days,
it's fundamental nature and behaviour is general purpose.
