I'd not create R1 just for paging.  I'd use those two drives to add to
your R 0+1 to give more spindles for your database.

Subject: Ahem, Server Configuration question for swap


Wise aged Exchange Pros:
Does putting the swap file on it's own spindle, gain much in
performance? Or is it better to just split the system mirror and put the
swap on the second half?

Proposed configuration is:
1. Mirror for system
1 Mirror for swap
1 Mirror for logs
1 Raid 0+1 for database

Total = 10 drives in this config
The Chassis holds 9 drives, so one option is to split the system mirror
for the swap partition or add an expansion chassis and move the database
to make room for the hot spare and keep the swap on its own spindles.

Performance isn't an issue, these boxes have MIPS to spare, but have any
of
you noticed a gain in performance by separating the swap?   Any of you
made
this decision, and why?
