3 TODAY S AGENDA Why use Virtualisation OVM Overview Benchmarks Conclusion Why Revera 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 VM Based on the underlying Xen hypervisor technology Management Linux Kernel with support of Devices (JeOS) IO, Networking, etc Guest OS with applications running on domu

9 MORE VALUE Key Benefits Application Aware Virtualization High Available and Scalable Easy and Efficient Centralized Management Fast Deployment and Standardization Application Driven Virtualization Soft and Hard Partitioning Support for Leading Enterprise Operation Systems Dynamic Resource Scheduling Integration with OEM12c Build by Oracle to Oracle and non-oracle environments Only x86 server virtualization solution fully certified by Oracle and can be used with all Oracle Software Single Vendor Support, One call to Oracle; no finger pointing at another vendor

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 bit Hitachi Storage (Fiber Channel Storage Array) Database OEE SGA: 4864 MB Redo: 7 Groups of 150 MB each

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 OVM uses less CPU than other Hypervisors PLUS a bonus: Allow licensing savings, extra HA and is fully certified and supported by Oracle.

41 WHY REVERA Over 2.0 Pb of storage and 2,500 VMs in operation 150 staff across four locations 5 data centers (small but perfectly formed) CommVault s biggest NZ customer VMware Premier VSPP in NZ Hitachi Data Systems biggest NZ customer Oracle Platinum Partner Biggest OVM farm in NZ Dozens of templates customized to achieve the best performance and stability Scalable Environment The only OVM specialized partner in NZ Constantly investing in Research

42 SELECTION OF UTILITY COMPUTE OPTIONS Targeted at different use cases All Utility Pricing scale up-scale down Different Service Offerings focused at different use cases Customers consume based on SLAs and capabilities, not brand of hypervisor
