- 33. 33 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 VMware Support - www.vmware.com/support/policies/oracle-support.html
- 34. 34 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.” http://www.oracle.com/us/corporate/pricing/olsa-ire-v122304-070683.pdf
- 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.
