with multi-VM trust zones
• vShield Edge protects the perimeter of
your virtual data centers
More cost effective than
physical firewalls
Simpler to manage than existing
solutions - dynamic security that
follows your application

Responding Faster Means Different Things
For Different Workloads
Test & Dev
Fast Provisioning
of new VMs
Ability to continuously
meet SLAs with little
human intervention
• 75% of provisioning is
for Test/Dev
• “Give me a VM … fast”
Production
• Provisioning doesn’t
happen often
• But change happens
fast and often

27. 27
Accelerate Time-to-Market for Business Critical Apps
• Faster testing of multi-tier applications
• More accurate testing on exact production copy
• Lower cost testing infrastructure
• Reduce storage footprint by over 60%

Officially Supported by Oracle (MyOracleSupport note 249212.1)
“Oracle will only provide support for issues that either are known to occur on the native
OS, or can be demonstrated not to be as a result of running on VMware”
www.vmware.com/support/policies/oracle-support.html
• Oracle RAC supported since Nov 2010
• VMware does not modify native OS
• Not a single reported incident of vSphere causing an
issue in the Oracle database or application
• VMware offers full support and total ownership
Oracle Certification and Support for VMware
Certified? - (Oracle Does Not Certify Infrastructure)
• Oracle does not certify anything below the OS. e.g. Dell, HP, IBM hardware
• Run an OS certified by both Oracle and VMware for confidence at every level
of the stack
• Will accept accountability for any Oracle-related issue reported by a customer
• Will help drive the issue to resolution

Licensing - Notes
 VERY IMPORTANT – PLEASE READ!
 Notes
• The information in this presentation is taken from publicly available sources –
details at the end
• We are not providing licensing information or guidance – we are just making
you aware of the information so you can make your own considered judgment
• This is a very complex subject – I will only cover license models under ‘normal’
circumstances – special agreements such as academic, campus or site
licenses are out of scope

35. 35
Oracle Licensing for Clusters
Licensing Clusters
• Partially licensed clusters
• DRS Host Affinity to restrict VM
mobility to licensed hosts only
• Oracle has no official stance on
such clustering technologies
• Fully licensed clusters
• Dedicated clusters when lots of
Oracle across test/dev/prod
• Load as many VMs as you wish,
with full VM mobility
“My Oracle rep tells me I have to license every server in the ESX cluster!”
But the Oracle OLSA says:
• “Processors where Oracle
programs are installed and/or
running“.
• License the entire server not the
entire datacenter.
• License the vSphere hosts where
your Oracle VMs actually run or
could run.
10 day rule
• “Right to run…on an unlicensed
spare computer…for up to ten
separate days in any given
calendar year.”

36. 36
Oracle Licensing – Key Points
 Key points to note
• VMware is Soft Partitioning according to Oracle
• Different DB Editions (functionality the main differentiator for EE)
• Processor Core Factors
• Restrictions around mobility
• High cost of DB is huge incentive to optimise and take advantage of
virtualisation.

37. 37
IBM Licensing – Key Points
 For me it is all about ‘Work’ – comprehend this and the licensing
will work for you
 Key points to note
• Processor Value Units are the units of currency
• Many people thinking about UNIX to x86 Application Server migrations
• Sub-Capacity licensing is usually the way to go
• Right size your VMs for optimum savings
 Understand the Software Density you can achieve
• Low Density – float your VMs around a big cloud and optimise VM size
• High Density – use clusters to pack workload and achieve big savings
• With IBM you have many options and can mix and match

38. 38
Microsoft Licensing
 The focus here is on Server OS and Server based Applications with
Microsoft Volume Licensing
 Quite similar to IBM but less focused on virtualisation
• Still High Density vs. Low Density
 New SQL 2012 licensing possibly signals a change to reflect both
Cloud and next generation compute power
 In 2008 they rules relaxed the 90-day rule
 Strong understanding of Server Farms
 Interesting restrictions on time zones and # of datacenters
 Server/CAL also allows mobility now
 I most commonly see silos of SQL (high density) – perhaps this
reflects many more clients have a quorum (!) of workload.
