SAFE HARBOR STATEMENT

The following is intended to outline our general product

• direction. 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, or functionality, and should not be relied upon in making purchasing decisions. The development, release, and timing of any features or functionality described for Oracle’ s products remains at the sole discretion of Oracle.

Early Stages – “Statelessness”

• Breaking the logical/physical

relationship between workload and its placement on hardware

• Key to automation and

modernization of a true “lights

• ut Data Center and remote

facilities management techniques

• “Statelessness” The key to the

adaptation of virtualization in the enterprise

Early Stages – Network Storage

• In a stateless system, Network Storage is key to the

architecture.

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

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

Early Stages – Configuration Repository

• “Statelessness” places the attributes of all workload

into 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) active

at any given time

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