At Oracle OpenWorld, Larry Ellison announced the new Oracle Exadata Storage Server based exclusively on the HP ProLiant DL180 G5 platform with HP storage technology.  I don't know much about this but from what I've read so far, this is pretty cool.    HP is the exclusive hardware and integration technology provider for the Oracle Exadata Storage Server.  I won't try to summarize what I've read but here are a few things to help you on your way:

• Blog by Forrester's James Kobielus titled Oracle Soars Into Petabyte Stratosphere, Puts HP-Powered Grid Storage At The Heart Of Its New High-End DW Appliance
• Dana Gardner ZDnet blog titled HP and Oracle team up on ‘data warehouse appliances' that re-architect database-storage landscape
• Dana posted another blog entry in which in interviewed my good friend and fellow HP blogger John Santaferraro.  You can find that by clicking here.
• One more, this time from a reporter; here's a link to a story at eWeek.

I'll get someone that is more knowledgable about this solution to post something in the next few days.
