“An estimated 70% of corporate technology budgets is spent on installing, updating and maintaining current technology “ as stated in New York times,april10,2012
Total Cost of Ownership (TCO) includes:
• Acquisition costs
• Implementation and Deployment costs
• Operations and maintenance (O&M) costs for three years

Comparison of Implementation Costs
Implementation includes hardware and operating system installation, networking, configuration, database installation and initial performance tuning. However, this TCO calculation excludes database migration, testing or installing applications, which the research found variable among customers and independent of which hardware they utilized
For example, Oracle RAC is typically deployed with Exadata configurations but not for IBM, IBM would require additional HA failover software to match this key Oracle capability. Also, the IBM P770 was selected not only because it is IBM’s latest generation but also because it is one of IBM’s most popular models to date, and also one of the customers interviewed had specifically migrated from a P770 to Exadata
The average Exadata implementation takes just 59% fewer man-hours than a traditional IBM Power System .

Comparison of Operations and Maintenance Labor:
A comparison of operations and maintenance labor for the whole Exadata versus IBM P770 plus the Oracle Database solution shows annual 9% man-hours benefit from using Exadata, primarily from 40% less hardware systems administration time (server and storage) because of the integrated nature of Exadata. The Oracle database maintenance cost is the same for both Exadata and P770. Because the bulk of the man-hours in this category are for the cost of the DBA (see table below), it obscures the overall maintenance cost savings for Exadata. In addition, the TCO model includes outsourcing Exadata software patches for the first year only, bringing that function in-house for years two and three as customers develop comfort with bundled patches.

Comparing the Acquisition Costs:
To compare acquisition costs, an IBM P770 solution was pitted against a Half-Rack of Exadata, with carefully selected configurations for each. Acquisition includes the one-time costs of purchasing the hardware and the software.
