[sf-lug] Dynamically Scalable Data?

For some reason, I'm perfectly ok with the scalability from the server and
application side.  (That may or may not be a bad thing)  :)  I guess what
I'm more after is tackling the issue of dynamic data availability (say due
to a spike in search traffic for a particular video or image).  Even within
that, I'm not really concerned with bandwidth per se, but more with the
ability of the data storage device (a SAN in this case) to scale it's output
on a certain finite data set within the larger warehouse.  With new tools
available in the storage world like dynamic data optimization, it is now
possible to redistribute data across the spindles in a SAN to increase
throughput out of the device itself onto the fiber network.  I am fleshing
out a way to take a dynamic event like a surge in search queries for a given
finite data set and translate that into an automated process or system than
can integrate with the storage management platform and dynamically scale the
throughput on the fly.  Then perhaps when the spike in interest subsides,
redistribute the data 'normally' to allow for the next surge to take
