In a podcast, Oracle Executive Vice President of Hardware Engineering, John Fowler discussed Oracle and Suns application to disk engineering and the benefits this will bring to customers. Hardware, operating systems, databases all can be tested together to ensure high performance, reliability, and energy efficiency for the customer.
A particular example of the integration work being done is the development of Solaris into the best operating system to run Oracle Database on. Oracle database performance and regression testing is also being run on all Sun server and storage. So, as Fowler said, you know when you get these products from us, as one company, they've been tested to work together and will be serviced at an extremely high level.
