SAFE HARBOR STATEMENT

The following is intended to outline our general productdirection. It is intended for information purposes only,and may not be incorporated into any contract. It is not a

commitment to deliver any material, code, orfunctionality, and should not be relied upon in making

purchasing decisions.The development, release, and timing of any features orfunctionality described for Oracle’s products remains at

the sole discretion of Oracle.

Early Stages – “Statelessness”

• Breaking the logical/physicalrelationship between workloadand its placement onhardware

• Key to automation andmodernization of a true “lightsout Data Center and remotefacilities managementtechniques

• “Statelessness” The key to theadaptation of virtualization inthe enterprise

Early Stages – Network Storage

• In a stateless system, Network Storage is key to thearchitecture.

• No local disk usage – everything is remotely mounted.• Most activity is concentrated on Server Virtualization,

but the migration of data to a network storage-centricapproach is crucial

Early Stages – ConfigurationRepository

• “Statelessness” places the attributes of all workloadinto an outside repository.

• Red Hat 5 – uses LDAP for this• EDCS uses an Oracle Database• Interfaces into Linux for all OS specifics ( hostname,

network configs, mountpoints, users and software)

EDCS Standard Provisioning “Grid”

• Stateless• PXE Booted• Network Disk Centric• All workload encapsulated into System Repository• BUT….

• Single OS to a single server (Server proliferation)• No Windows support• Big Flat Network

Enter: Server Virtualization

Project DAKOTA

• Encapsulation of the computing environment• Network, Server, Disk all “Disposable”• Support of Windows alongside of Solaris and Linux

Project Dakota

• Network Encapsulation:• SSL-VPN Tunnels and ACLS

• Disk Encapsulation• Net Apps “Flex Cloning”

• Server Virtualization• Xen

Project Dakota

• Live Production – May 2005• Linux only, Paravirtual only, on non-VT enabled hardware• 3 to 1 Collapse of server proliferation• As updates to Xen became available – new features were added:

• March 2006 – Windows• October 2007 – Solaris Para-virtual

• All Oracle software is in some form of Xen enabled virtualization (not for external support )

Project Dakota

• Current Status – Global IT and Oracle University• 240 Dell 1950s

• Roughly 4,000 grid “instances”** (virtual machines) activeat any given time

• Wide variety of OS’es, Windows, Linux and now Solaris.
