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?

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

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”

The Virtual Data Center

7


Key Concepts in the VDC

• Non-proprietary Components– Small (i.e., 1-, 2- and 4-way servers)– Low cost– Industry standard– Commodity– Powerful

• High-performance Interconnect– Low latency– Low contention– High throughput

• Dynamic Reallocation– Workload– Resource

• Transparency– Applications are “unaware” of the dynamic environment– No special programming needed

8


Workload and Resource Balancing

Cluster A Cluster B

9


Key Balancing Concepts

• Workload balancing takes place within clusters

• Resource balancing takes place between clusters

10


The Oracle Grid

• An evolving architecture

• Across Oracle products (database, RAC)

• Provides for– Cluster resizing– Data migration– OS and platform transparency

• Exciting future directions!

Oracle’s grid computing is a prime exampleof scalable enterprise computing

11


Oracle Grid Components*

• Real Application Clusters (RAC)

– Workload balancing within a cluster

• Transportable Table Spaces

– Bulk data migration

• Streams

– Data distribution and synchronization

• Distributed SQL and transactions

– Execute queries across multiple databases

• Generic connectivity

– Allows inclusion of non-Oracle databases on the grid*From “Oracle and the Grid: An Oracle White Paper”, November, 2002, Oracle Corporation. http://otn.oracle.com/products/oracle9i/grid_computing/OracleGridWP.pdf

Summary

• Scalable Enterprise Computing

– Low cost, availability, and performance

– Standard, commodity components

– Sized for current demand

– Scales easily – “pay as you grow”

– Virtualization through software

– Transparent to applications

• Dell’s role

– To provide “virtualization-ready” components

• Oracle’s role

– To provide virtualization through the Oracle stack
