  4. 4. Milestones of Virtualization technology OVM on Commodity HW & Engineered Systems4 3/27/2016 Thanks to the Virtualization technology it has been possible: To abstract the underneath HW and replace expensive SMP systems with commodity hardware. To dynamically and elastically allocate resources to the applications. To live migrate servers on different HW even across data centers. To reduce the time to market from days to minutes using pre-built VMs and Templates. To consolidate independent projects on the same infrastructure without compromising performance, security and independent lifecycles.

  7. 7. Overview of OVM x86 2/2 OVM on Commodity HW & Engineered Systems7 3/27/2016 Oracle VM Server incorporates Xen Hypervisor, developed and maintained as free and open-source software. It runs as most privileged domain (Dom0) on the hosts which are part of the virtual server farm. The hypervisor responsibilities include abstracting elements from the physical machine, CPU scheduling and memory management of all Guest VMs. Oracle VM Server includes Oracle VM Agent, responsible to communicate with Oracle VM Manager. Oracle VM Manager is a web based management console, developed and maintained by Oracle to administrate Oracle VM Servers, VMs, Templates, ISO images etc. Oracle VM Manager runs independently and separately from the rest of OVM infrastructure and it is not a mandatory components. In fact the OVM farm can be entirely managed using Xen commands. +
  8. 8. OVM x86 on Oracle Database environment OVM on Commodity HW & Engineered Systems8 3/27/2016 For long time beyond all licensing restrictions, the usage of the virtualization has been discouraged due to the non-optimal I/O performance. Today Oracle is promoting OVM on its Top Database Engineered Systems (Exadata, ODA) what has changed? The implementation (starting from OVM 3.1) of the PCI device virtualization technology: Single Root I/O Virtualization (SR-IOV).
  9. 9. OVM x86 on Oracle Database environment OVM on Commodity HW & Engineered Systems9 3/27/2016 SR-IOV is a PCI device virtualization technology that allows a single PCI device to appear as multiple PCI devices on the physical PCI bus: the real physical device is called Physical Function (PF) while the others are called Virtual Functions (VF). The purpose of this is for the hypervisor to directly assign one or more of these virtual functions to a virtual machine using Intel VT-D technology: the guest can use the virtual function as any other directly assigned PCI device.

  15. 15. Why OVM on database Engineered Systems? OVM on Commodity HW & Engineered Systems15 3/27/2016 OVM on Oracle Database Appliance – Oracle Database Licensing optimization – Leverage HW utilization with Solution-in-a-Box – Consolidate multiple Applications on one system OVM on Oracle Exadata Machine – Best Database Cloud environment with up to 64 Grid Infrastructure clusters – Database Consolidation & Isolation with independent lifecycles. – Dynamic resource allocation
  16. 16. OVM on Commodity HW & Engineered Systems16 3/27/2016 OVM on Oracle Database Appliance Unique OVM characteristics: 1) Dom Base is a privileged VM with direct access to the shared storage. This guarantees almost native I/O performance to the databases. 2) No Oracle VM Manager is available, Xen commands have been included on the oakcli CLI framework.
  17. 17. OVM on Commodity HW & Engineered Systems17 3/27/2016 OVM on Exadata Unique OVM characteristics : 1) Domain C<x> are privileged VMs with direct access to the InfiniBand network. This guarantees almost native I/O and Network communication performance to the databases. 2) No Oracle VM Manager is available at this date, Xen commands should be used to manage the virtualization layer.
