Our very own Brian G is back at the podium to talk about all the SAN stuff no one in the database world seems to talk about but we all have to understand.

Your job is to use up disk resources and the SAN man's job is to protect and keep those resources. So the fight is on! G.I. Joe says knowing is half the battle. Here's some of what Brian will arm you with:

What is a SAN Anyway?

  • Common SAN Data Protocols

    •   i-SCSI
