VM with offloaded anti-virus

• vShield App protects the applications

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

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

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

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

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

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.
