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

• 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
Virtualization Strategy Oracle VM 3.x Oracle Linux
OEM12c Xsigo Q&A
Wait, What? Oracle RAC on OVM? Really?
![Page 24: Virtualization Strategy with Oracle VM and Oracle Linux · PDF fileVirtualization Strategy with Oracle VM and Oracle ... • Fully certified and supported by Oracle • Oracle does](https://reader031.vdocuments.net/reader031/viewer/2022021419/5a908b877f8b9a085a8e47ee/html5/thumbnails/24.jpg)
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
