I think its interesting that Oracle has allowed so much time to their partner/competitor EMC and VMWare in the Monday morning keynote. The value of EMC's big data strategies, Greenplum, VMWare and EMC Storage w/vfast are all being shown to Oracle's best customers.
They're talking about "Cloud meets big data"...and showing they can get 1 million iops with vfast storage in VMWare..like Exadata, while making available all the virtualization features we've become used to, like snap/clone.
Pared with Greenplum and hadoop, peyabytes are analyzed in seconds. It'll be interesting to hear Exahadoop's and Exalytics response. :)
Here's a pic of an Exalytics server:
