Questions

4. BEFORE START
 REVERA is a IaaS leader provider in NZ with many
different options and solutions available to fulfil any type
of requirement.
 The results on this presentation makes only reference
regarding Oracle Database performance when running
on a virtual environment.

5. WHY USE VIRTUALISATION





Consolidation of workload
Hardware independence
Enhanced high availability & DR options
Better utilisation of overall CPU & RAM, ability to redistribute
Overall significantly better value and better utilisation of
resources

6. WHAT IS OVM
Oracle VM is an enterprise-proven server virtualization
solution comprised of Oracle VM Server for x86, Oracle VM
Server for SPARC and Oracle VM Manager that is scalable,
and a low-cost server virtualization solution for both Oracle
and non-Oracle workloads that makes enterprise
applications easier to deploy, manage, and support.

7. WHAT IS OVM (Cont)
Because OVM is build by Oracle all Oracle products
deployed in Oracle VM such as the Oracle Database,
Oracle Fusion Middleware, Oracle Applications, and Oracle
Real Application Clusters and many others are fully
supported and certified.
OVM helps customers improve server utilization, achieve
higher availability and achieve better performance while
reducing costs.

8. THE ARCHITECTURE
 OVM Server
– Based on the underlying Xen
hypervisor technology
– Management Linux Kernel
with support of Devices
(JeOS)
– IO, Networking, etc
 VM
– Guest OS with applications
running on domU

10. BENCHMARK
Environment Preparation

11. SOME NOTES ON THE TESTING
 Performed in a lab environment, not on our actual Prod
environment
 The trends are representative, but the numbers reflect the lab gear
available at the time
 When we build VM service offerings they are tuned for general
purpose IaaS workloads & use cases most common across
customers
 We can tune for specific use cases, as this presentations will show

12. THE ENVIRONMENT
 Hardware
– 3 DELL M610 with 96 GB
RAM and 2 hexa-core
processors each
– OS: OEL 5.7 64 bit
– Hitachi Storage (Fiber
Channel Storage Array)
 Database
– OEE 11.2.0.3
– SGA: 4864 MB
– Redo: 7 Groups of 150 MB
each

13. THE SERVERS
 VM’s
– 4 vCPU’s each
– 6 GB RAM each
 Virtualization Software
– OVM 3.2.1.516
– Other Hypervisors
 Bare metal
– 12 CPU’s
– 96 GB RAM

14. BENCHMARK PRODUCTS
 CPUmonitor 2.91
 Swingbench 2.4

26. BENCHMARK/SCALING
What happen if we give more resources to the VM?

27. WHEN SCALING
• Increasing VM resources on-demand when
achieving 400 concurrent sessions
• RAM from 6GB to 12 GB
• vCPUs from 4 to 8
Now let’s see
what’s happen
when giving more
resources to the
VM

32. WHEN SCALING
As you can see, without OVM
you will have a full physical
server with underutilized
resources, but if using OVM,
you will be able to virtualize it to
host many Oracle DBs without
loss of performance and making
an efficient use of available
licenses.

33. OTHER INFO
• MANAGEMENT OF SGA MEMORY
• SGA of 4864 MB
• BM able to open 563 connections
• Other Hypervisors able to open 523 connections
• OVM able to open 567 connections

34. BENCHMARK
Conclusion

35. MYTHS or TRUE
•
•
•
•
•
It is not safe to run Production Environments on OVM
If using OVM your database will run slower
Oracle do not support production DB on OVM
OVM is more expensive than other Hypervisors
Other Hypervisors run Oracle Database faster than OVM

36. CONCLUSION
•
•
•
•
•
Oracle Database performs better at OVM
OVM makes a better use of available resources
OVM is more scalable and stable for Oracle DBs
OVM allows better consolidation of loads in a virtual environment
PLUS
OVM uses less CPU than other Hypervisors a bonus:
Allow licensing
savings, extra HA and
is fully certified and
supported by Oracle.
