Any value in defraging a SAN drive?

Are there any quantitative findings published that show there is any merit in
defragging a SQL device on a SAN?

I would check with your SAN vendor about this. However, quoted from this
MS page:
http://www.microsoft.com/technet/pro.../ss2kidbp.mspx
"On large-scale environments that benefit from more intelligent disk
subsystems, such as SAN (storage area networks) environments, correcting
disk fragmentation is not necessary."
In any case, your vendor should provide you with recommendations.
