Database & Disk Deck
I have posted the deck I give at conferences on database and disk drives. It's a "shorter" deck (ie. One hour talk), instead of the larger deck I sometimes use that covers 4 hours.
A short abstract:
It focuses on how to create a scalable database solution on everything from direct attached SCSI to SANs. The deck covers perfmon counters, partition alignment, SQL IO performance testing, proper number of files for space management, etc...
