    • <Insert Picture Here> Virtualization: From Hypervisors to RAC
    • SAFE HARBOR STATEMENT The following is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions. The development, release and timing of any development release, features or functionality described for Oracle’s products remains at the sole discretion of Oracle.
    • Virtualization Abstraction is the Key word! Means a lot of things too! 3
    • Definition In computing, virtualization is a broad term that refers to the abstraction of computer resources 4
    • Physical Example • Virtualization and Cloud are abstract concepts. Very y Hard to explain in the physical world. • I have a conceptual example h t l l • I am considered a resource consumer • I want access to water ( y resource) a t ate (my esou ce) • Lets walk through some grounding concepts 5
    • My Own Water Well (direct physical) • Exclusive Physical Access • Large initial capital expenditure (CapEx) • Measure direct usage with the correct instrumentation • I am responsible for maintaining service to my i i i i water 6
    • Through Water Service (Virtualized) • Water is still available to me within my house but I no longer have y g direct exclusive access to the water source. I do not care, I still have my water. • Others may be sharing the water but I cannot tell. Physical origins of the water are unknown to me Hard me. to measure total usage. • Long term contract with water company • Less CapEx than a well with some p OpEx (chargeback from water co.) 7
    • Buy from Vendor (Cloud) • Quick, temporary access to water • Pure OpEx, no CapEx (no well needed) • Different quantities and sizes but all contain water. • Slight packaging difference (need to abide to Cloud operators packaging) • No Long term contracts needed. Access as needed, when needed, for as long as needed 8
    • Cloud Computing * Often characterized by: • Agile Virtualized computing resources • Multi-tenancy • Seemingly limitless capacity/scalability • Self-service • Dynamic provisioning • Pay-for-use pricing * Source: Wikipedia.org 9
    • Virtualization Recap? • Abstracts the physical resource into a virtualized y resource that can be shared •B Benefits fit • No need to worry about the physical anymore provided the virtual interfaces are present • E.g which type of hardware I run on • Increase utilization of the physical resources by having more virtualized consumers • Reduces complexity 10
    • What Can Oracle Virtualize? Application Services Virtualization Infrastructure Virtualization • Business Service • Database Virtualization Orchestration • RAC virtualizes the DB • SOA/BPM • Application Server Virtualization Infrastructure Virtualization • WebLogic Server Suite • Data Virtualization • Server Virtualization • Coherence In-Memory • OVM Data Grid • Storage Virtualization • ODI virtualizes data repositories • ASM virtualizes LUNs • OVD virtualizes d t i t li data directories 11
    • State of Virtualization Source: IDC • Server virtualization is now considered a mainstream technology among IT buyers • IT professionals are very bullish on future use • 22% servers virtualized today with 45% in 12 months • Core infrastructure and data center strategies are being turned upside down! • Virtualization product expectations are climbing quickly ... but satisfaction is very high! • Virtualization impacts more than servers • Storage, networks, clients, management, security, etc. 12
    • Server Virtualization (just one type) Server Vi t li ti S Virtualization Server P li (G id F S Pooling (Grid, Farm, A Array, F b i ) Fabric) 13
    • Grid and Virtualization Virtualization Oracle Grid Linux Unix Windows Virtualization Layer 9i,10g,11g Large powerful Multi-CPU server Makes one big server look like Makes lots of separate small lots of separate small servers servers look like one big server Virtualization within a resource Virtualization across resources 14
    • Server Virtualization Technologies 32 Cores 4 O/S 4 App O/S O/S App 4 O/S O/S App O/S 20 App O/S O/S O/S Hypervisor HW Partitioning OS Containers Virtual Machines • Physically carve up the • One O/S • Hypervisor on top of HW box • Each App isolated from • Independent O/S’s • Independent O/S’s other Apps 15
    • Customer Value Server consolidation Hard Cost Savings S i 70-80% reduction in datacenter space, power infrastructure Server rebuild and application load Operational went from 20-40 hrs =>15-30 min Efficiency Easily reallocate server resources Live Migration Availability Virtual Machine failover 16
    • Cost Benefits - Examples • Oracle VM Server Virtualization Benefits: • O l O Demand Oracle On D d • 67% reduction in hardware • CPU utilization increased from 9% to 55% • Oracle University • 83% reduction in hardware • CPU ut at o increased from 7% to 73% C U utilization c eased o % 3% • Revenue per server increase 5X • Floor space consumption reduced 50% • Data center power consumption reduced 40% • Greatly simplified server refresh 1300 environments automatically provisioned weekly • Servers to administrator ratio increased 10X 17
    • What’s a Hypervisor • The Water Company is the Hypervisor. Hypervisor • Manage the relationship between the physical (wells reservoir (wells, reservoir, pumping stations) and the virtual (homes wanting water). • The Water Company understands which home is using the water and how much real water is being used used. It “Brokers” the physical resources 18
    • Oracle Support Policy Metalink Doc ID: 249212 1 249212.1 Our standard support policy for third-party products applies to Oracle application and database servers running on virtualization software: • Where specific virtualization technologies are not certified, Oracle will not turn away a customer reporting an issue solely due to the use of these technologies. • Oracle Support may attempt to replicate the issue in a non-virtualized environment and work with the customer to verify if the problem exhibits in such an environment. • Specific problems isolated to virtualization software that cannot be reproduced in standard Oracle environments -- i.e. environments without virtualization software -- may need to be referred to the third-party vendor for advanced debugging and resolution. • Customers should review all relevant Oracle and 3rd-party documentation on the use of such virtualization technologies for known issues and limitations with respect to the technology components such as the application, middleware, database, etc. • Customers intending to use 3rd-party products in production environments should conduct appropriate levels of testing and also have contingency plans to revert to a standard certified configurations. 19

    • Partitioning – Virtualization Licensing Soft Partitioning: 1. Soft partitioning segments the operating system using OS resource managers. 2. 2 The operating system limits the number of CPUs where an Oracle database is running by creating areas where CPU resources are allocated to applications within the same operating system. 3. 3 The database administrator can set the number of CPUs to the number of licensed CPUs. 4. This is a flexible way of managing data processing resources since the CPU capacity can be changed fairly easily, as additional p y g y y, resource is needed. 33
    • Soft Partitioning Examples Examples of such partitioning type include: 1. Solaris 9 Resource Containers 2. AIX Workload Manager 3. HP Process Resource Manager 4. Affinity Management 5. VMWare 6. Oracle VM - can also be used as hard partitioning technology** This is not a comprehensive list of all the different types of technologies or resource allocation devices/programs that would fall into the category of Soft Partitioning. 34
    • Hard Partitioning 1. Hard partitioning physically segments a server, by taking a single large server and separating it into distinct smaller systems. 2. Each separated system acts as a physically independent, self- contained server, t i ll with it own CPU operating t i d typically ith its CPUs, ti system, separate boot area, memory, input/output subsystem and network resources. 35
    • Hard Partitioning Examples Examples of such partitioning type include: 1. Dynamic System Domains (DSD) -- enabled by Dynamic Reconfiguration (DR) 2. Solaris 10 Containers (capped Containers only) 3. LPAR (adds DLPAR with AIX 5.2) 4. Micro-Partitions (capped partitions only) 5. vPar and nPar 6. Integrity Virtual Machine (capped partitions only) 7. Secure Resource Partitions (capped partitions only) 8. Static Hard Partitioning 9. 9 Oracle VM - can also be used as soft partitioning technology** 36
