•  Virtualization offers cost savings benefits –  Server consolidation –  Lower energy, facility and labor costs –  Lower Licensing Cost

•  Virtualization offers additional benefits –  Standardization –  Isolate Applications –  Optimize Resources


OEM12c Xsigo Q&A

Benefits of Virtualization

8

Oracle’s Virtualization Strategy “Virtualization that makes software easier to deploy, easier to manage, and easier to support. Not Virtualization for Virtualization’s sake.”

Oracle VM 3.x for x86 Virtualization Strategy


OEM12c Xsigo Q&A

10

•  for both Oracle and non-Oracle applications •  The only x86 server virtualization software supported

and certified for all Oracle software •  Almost no hypervisor overhead •  Used in Oracle’s Engineered Systems

(ODA, exadata, exalogic and exalytics) •  Can be used to limit your license cost of Oracle

Products

Positioning

OEM12c Xsigo Q&A

Positioning Continued

•  Oracle is in the “Challengers” quadrant.

•  This is a significant “jump” above the x-axis

•  The move into the “Challengers” quadrant was possible for 3 primary reasons

1) Strength of Oracle VM 3.0 2) Integrated management 3) Solid customer momentum •  Gartner even specifically states

that Oracle VM use is growing amongst VMware customers

OVM Features – Assemblies & Templates Continued


OEM12c Xsigo Q&A

17

•  Better known as Omotion/Vmotion •  SSL encryption at a button press •  Allows you to have Planned Downtime at ANY time

OVM Features – (Secure) Live Migration


OEM12c Xsigo Q&A

18

•  Makes it possible to perform storage tasks from within the OVM manager Virtualization Strategy


OEM12c Xsigo Q&A

OVM Features – Storage Connect Plugins

19

•  Optimizes virtual machine CPU/Network resource utilization in a server pool.


OEM12c Xsigo Q&A

OVM Features – DRS

20

•  Used to increase the consolidation ratio of VMs into least amount of OVM Servers required.


OEM12c Xsigo Q&A

OVM Features – DPM

21

•  ensures that specific virtual machines don’t run on the same OVM server.

•  Usefull for –  Oracle RAC –  Load balancing Applications –  Relying on built-in redundancy of Applications


OEM12c Xsigo Q&A

OVM Features – Anti-Affinity

22

•  Auto Restart on OVM Level

•  Clusterware on OS Level

•  RAC on Database level –  Requires Rac licenses


OEM12c Xsigo Q&A

OVM Features – High Availability

23

•  It Works! •  Fully certified and supported by Oracle •  Oracle does it! ( ODA, Exadata) •  But why do it? –  Consolidate your RAC Servers –  Create Virtual Clusters for demo/test/dev –  Deploys fast –  Use Hard-Partitioning


OEM12c Xsigo Q&A

Wait, What? Oracle RAC on OVM? Really?

24

•  Soft-Partitioning ( default ) –  License largest server in the pool –  f.e. 10 servers in pool running 3 vm’s with Oracle

Enterprise Edition software => need to license 3 largest servers.

•  Hard-Partitioning –  Only on OVM accepted as a way to limit licenses –  Works by pinning CPU’s to specific VM’s –  Loose the ability to Live Migrate, use DRS or DPM


OEM12c Xsigo Q&A

Licensing of Oracle Products on OVM

25

•  Open Public Beta for OVM 3.2.1 •  Support for Oracle VM Server for SPARC •  Health Monitoring & Statistics from within Manager •  Enhanced OVM Manager CLI and Web Services API •  MySQL Database Support •  Updated Dom0 Kernel in Oracle VM Server for x86 •  Lots of other improvements


OEM12c Xsigo Q&A

OVM Roadmap – What’s new?

26

OVM Summary

•  Pricing –  Free License, Pay for support –  Oracle Enterprise Manager included in support

•  Strengths –  Application-Driven Virtualization –  all oracle products are certified and supported –  Templates Templates Templates –  Soft/Hard Partitioning to limit Oracle Licenses

How to continue from here

•  Read the user manual •  Read the release notes •  Avoid Common pitfalls

–  Check your hardware compatibility –  Check Bios Settings –  Choose PVM ( for now )

•  Plan your setup •  Start with Tier 2 ( dev/test ) •  Don’t expect miracles •  Feel free to Contact us

Oracle Linux Virtualization Strategy


OEM12c Xsigo Q&A

30

•  Compatible with Redhat Enterprise Linux •  Free to download, use and distribute •  Free source code, patching and binaries •  Oracle’s base development platform •  Used in Oracle’s Engineered Systems •  Dedicated Teams for QA/DEV and Support •  Oracle now recommends only the Unbreakable

Enterprise Kernel for all Oracle software on Linux


OEM12c Xsigo Q&A

Positioning

31

•  Unbreakable Enterprise Kernel •  Preinstall RPM’s •  Data Integrity •  Ksplice •  Cgroups
