� Extreme Performance dramatically lowers cost<br />
– Workloads that require huge traditional systems run on small <strong>Exadata</strong>s<br />
– Hardware needed for an application is often reduced 10x<br />
� <strong>Exadata</strong> also delivers Extreme Capacity<br />
– Huge disk footprint for large or less active data<br />
� 500 TB of disk per rack for historical data, low activity data,<br />
images, documents, backups, etc.<br />
– Columnar compression expands disk and memory capacity 10x<br />
– Blend of tiers gives highest performance at lowest cost<br />
� Placing all data in DRAM would cost $20M just for chips
