1. MicroTerabyte Leveraging InfiniBand to Build a Powerful, Scalable Oracle Database and Application Platform Brian Dougherty Chief Architect, CMA

2. Background Exploding data volumes are presenting new challenges to small and medium sized organizations. These organizations need a new generation of technology that delivers powerful analytical capability with reduced cost and complexity. CMA, in partnership with Dell, QLogic, Oracle, and EMC, has developed a sophisticated solution to address this growing need.

3. MicroTerabyte Platform What is It ? A pre-configured, integrated, fault tolerant, high performance, commodity hardware and software based runtime environment Leverages the power of the Oracle database running on commodity Linux servers, and a unified InfiniBand fabric over QLogic multi-protocol fabric directors Provides a scalable, reliable, lower cost platform for Business Intelligence, Custom Software, or Commercial Software
