Sorry if the point of the question is not clear. In a RAID/NAS/SAN
backend situation, ALL DRIVES are in effect the
same PHYSICAL DRIVE so
that's why I ask why one would still be recommended to have a separate
filesystem.
Ping? Nobody? So no idea why a separate dedicate virtual drive is
recommended for the pagefile.sys?
Frankly, the dimension of your case is beyond my experience.
All I can think of is the usual issue:
A separate filesys, or rather a separate *drive*, for swap reduce
butterfly-seeking for the read-write arm in the drive, because the
drive don't have to satisfy regular IO alongside page swapping.
This makes the swapping faster and more efficient.
I guess this applies even if you've got local striped raid volumes,
or you swap over a fiber, because in the end it all comes down
on a harddisk (or several).
