Virtualization

Abstraction is the Key word!

3

Means a lot of things too!

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 yHard to explain in the physical world.

I h t l l• I have a conceptual example

• I am considered a resource consumer• I am considered a resource consumer

• I want access to water (my resource)a t access to ate ( y 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 instrumentationthe correct instrumentation

• I am responsible for i i i imaintaining service to my

water

6

Through Water Service (Virtualized)

• Water is still available to me within my house but I no longer have y gdirect 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 Hardthe water are unknown to me. Hard to measure total usage.

• Long term contract with waterLong term contract with water company

• Less CapEx than a well with some

7

pOpEx (chargeback from water co.)

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

for as long as needed

Often characterized by:

• Agile Virtualized computing resources• Seemingly limitless capacity/scalability• Dynamic provisioning

• Multi-tenancy• Self-service• Pay-for-use pricing

Virtualization Recap?

• Abstracts the physical resource into a virtualized yresource that can be shared

B fit• Benefits• 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

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!turned upside down!

• Virtualization product expectations are climbing quickly ... but satisfaction is very high!

• Virtualization impacts more than serversVirtualization impacts more than servers• Storage, networks, clients, management, security, etc.

What’s a Hypervisor

• The Water Company is the HypervisorHypervisor.

• Manage the relationship between the physical (wells reservoirthe physical (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 usedhow much real water is being used. It “Brokers” the physical resources

Oracle Support PolicyMetalink Doc ID: 249212 1Metalink Doc ID: 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.

Partitioning – Virtualization Licensing

Soft Partitioning:

1. Soft partitioning segments the operating system using OS resource managers.

2 The operating system limits the number of CPUs where an Oracle2. 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 The database administrator can set the number of CPUs to the3. 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:Examples of such partitioning type include:

1. Solaris 9 Resource Containers2. AIX Workload Manager3. HP Process Resource Manager4. Affinity Management5. VMWare6. 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 categoryor 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-t i d t i ll ith it CPU ticontained server, typically with its own CPUs, operating

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 nPar6. Integrity Virtual Machine (capped partitions only)7.
