2. Product Group Copyright ©2003 Dell Inc. All rights reserved. 2 Presentation Goals What is Dell’s “Scalable Enterprise Computing” initiative? What are the characteristics of the “virtual data center?” How does Oracle ® grid computing fit with these concepts?

3. Product Group Copyright ©2003 Dell Inc. All rights reserved. 3 Yesterday’s Data Center Focus was on availability and performance – Cost a secondary issue Achieve with clusters or large SMP systems Statically sized for peak demand Resulted in underutilized resources – “Overprovisioned” – Peak demand does not occur simultaneously on all clusters Availability Performance Cost

5. Product Group Copyright ©2003 Dell Inc. All rights reserved. 5 What We Need Is… Flexibility – Logically “move” resources around the data center as needed – Could be “moving” hardware, software or data Cost Efficiency – Purchase enough hardware to service the average needs of the data center, not the aggregate peak load – Uses low-cost, standard, commodity components Scalability – As overall demand increases, add more of the smaller components – “pay as you grow”

Oracle’s grid computing is a prime example of scalable enterprise computing
