2. SAFE HARBOR STATEMENT

3. Early Stages – “Statelessness”
• Breaking the logical/physical
relationship between workload
and its placement on
hardware
• Key to automation and
modernization of a true “lights
out Data Center and remote
facilities management
techniques
• “Statelessness” The key to the
adaptation of virtualization in
the enterprise

4. 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

5. 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)

6. 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

7. Enter: Server Virtualization

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

9. Project Dakota
• Network Encapsulation:
• SSL-VPN Tunnels and ACLS
• Disk Encapsulation
• Net Apps “Flex Cloning”
• Server Virtualization
• Xen

10. 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 )

11. 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.

12. Oracle Grid-Based Computing
• Grid-Based Storage
• Oracle Automatic Storage Management
• Grid-Based Server Clusters
• Oracle Database
• Oracle Middleware
• Grid-Based Management
• Oracle Grid Control
