Exadata V2 OLTP?
"Exadata V2 appliance is not as good at data warehousing as it is at online transaction processing"
Just because it is not good at BI compared to Teradata/Netezza/IBM does not make it good at OLTP. The whole Exadata compression off load engine does not even work if the data is changing. The TPC-C benchmark was done on SPARC and had the cache fusion software turned off.
Last time I looked they didn't have a single benchmark for Exadata and only the $10M challenge which no corporate lawyer would ever approve with the T&C's.
Larry, the Kat and the Turd are going to have a hard time selling a $10M/rack "appliance like" mashup of Sun inferior x86 systems.
