Oracle Exadata 1/8 Rack vs. Oracle Database Appliance ODA

We do a lot of work with the Oracle Identity and Access Management Suite and many of our customers do not have a ton of experience with the Oracle Database, nor do they want a huge Oracle infrastructure.  What they do want is high availability and reliability on the platforms underpinning their IAM solutions.  Over the years we have recommended Oracle’s Database Appliance for many of these situations.  They are great little machines that don’t require extensive DBA knowledge to manage them.  In recent years they have also added the ability to do virtual machines on top of them which introduces some other awesome opportunities (OAM/OIM in a box!)

Recently we ran across a salesman that was pushing our customer into using an Exadata 1/8th rack instead of the ODA. We put together this handy little spreadsheet for the customer.

The ODAs really are powerfull little machines. We’ve run them at customers for 6+ years with no issues at all. Oracle really has a great solution in them that is overlooked by many organizations.
