Hardware Partitioning
Mem
• Primarily desktop
• Easy to use
• Very slow (2 OSes)
• Excellent isolation
• Expensive, proprietary hw
• Coarse grain resources
• Mix OSes / versions
• Only moderate isolation
• Potentially good scalability
• Fine-grained resources
• Cannot mix OS/patch levels
• Excellent isolation
• Affordable, multi-source HW
• Fine-grained resources
• Mix OSes / versions
Strategic Engagement:
What is needed• Now:
• Leverage Virtualization to decrease cost and improve performance
for enterprise applications:
• Test/Dev – automate builds and testing
• Scalability On Demand
• HA and Disaster Recovery
• Better TCO for in-house, hosted, and SaaS models
• Strategically:
• Make your products “virtualization friendly” to live in a dynamic world
• Use and define APIs that differentiate you
• View the virtualization layer as a option on your product…how
should it work?..
• To make your product more flexible, scalable, and efficient
• To make your product easier to deploy, manage, and support
Strategic Value Delivering on “Cloud Computing”
• Oracle VM is the virtualization layer for implementing
“private clouds” in the Oracle data center
• Other “cloud” packaging / initiatives for Oracle
products requiring virtualization should incorporate
Oracle VM
• Oracle VM is the “cloud” infrastructure and Oracle VM
Templates are the way to deploy solutions to the
“cloud”
• Please contact Oracle as appropriate if embarking on
any cloud efforts so we can align and assist

Anatomy of an Oracle VM ServerKey Concepts: Dom0 & DomU
• “Dom0” is a privileged management
and control domain typically
containing…
• A thin control kernel based on Oracle
Enterprise Linux
• Open / native Linux device drivers
• Oracle VM Manager agent
• Device emulation code to support
non-PV guests (e.g. Windows)
• Dom0 should not contain „user‟
applications as a best practice
• Minimize performance & security risks
• Minimize code size
• “DomU” is an unprivileged/user
domain that is a guest VM on the
server
• Run any normal server workload
• One domU is not aware of another

• Varying SGA size, # of users, # of vCPUs
• Typical OLTP workloads
• Results:
• On average three times less overhead compared server virtualization products from other vendors.
• Virtual SMP scalability of Oracle VM is at 90+%
• Open source benchmark tools
• Replicate with your configuration & products

Oracle VM: Proven Deployments Across Multiple Industries
"Oracle VM was a better option because VMware was cost-prohibitive for
us, as was Citrix XenServer. We had already made a substantial investment
in Oracle, and they offered us a much better deal than either of the others.” - Nicholas Tang,
VP of technical operations, Interactive One LLC 28 October, 2008
University of Massachusetts CTO Michael Poole said that Oracle [VM]
"solution best supports the university's requirements for on-demand
availability of applications and database services.”

Free Distribution of OEL and VM
• Oracle VM and OEL is free to download for partners and
customers. Freely redistributable with an option for support
- this can be a big benefit for you and your customers and
is pretty unique in the industry.
• A slimed down version of Oracle Enterprise Linux, the
JEOS edition, allows partners (and customers) to create
small virtual machines/templates - this is also freely
redistributable.
• It‟s possible to support the complete stack under an ISV
application with just you and Oracle.
Oracle Products Licensing
With Oracle VM
• Other products use their existing licensing
model
• Often physical CPU based
• No new per instance charges
• Soft and hard partitions
• Hard partitions enable sub-server licensing
• Oracle VM can be configured both ways
• Significant benefits for consolidated
environments
