Oracle Exadata Review
If you have resources to integrate your own hardware and Software, you don't need Exadata

Valuable Features:

Exadata is Oracle's solution for a fully Engineered Integrated Hardware and Software platform for Oracle Databases. Extensive Storage level features such as Smart Scan, Flash Cache and Hybrid Columnar Compression. The Infiniband Switch is very fast for all communication channels. Excellent performance gains especially for large data warehouse types of applications.

Room for Improvement:

OLTP applications with smaller data footprints don't tend to gain too much from Exadata hardware. The majority of benefits are reaped by applications which are i/o bound and caching helps a great deal with that. Oracle manages the entire hardware and software including database and OS patches but companies need to pay heavily for that service. It is expensive hardware compared to integrated commodity hardware and software.

Other Advice:

The Infiniband switch has some distance limitations and a true DR (Disaster Recovery) site cannot be setup with Exadata, The operating system allowed is ONLY OEL (Oracle Enterprise Linux) which is a big limitation. One has to go through Oracle's support system - tickets and service requests to make any changes to the Exadata machine.
Disclosure: I am a real user, and this review is based on my own experience and opinions.

Whoever is the "Oracle Support" that does the initial setup seems to think that one-size-fits-all it the solution to every application environment. Still seems to be the approach of the 1980s that if the menu comes up then the setup is complete. For all the money and hoopla it is a disappointment to have to struggle with memory issues when doing simple tasks like adding large numer of partitions.
