Oracle Data Centre Rationalisation

A Practical View

Ian Gardner - Oracle Applications Architect 2012-06-13

Why perform Oracle Data Centre Rationalisations...

Reduce Costs

associated with multiple locations – Power, management, cooling, lease...

Increase Resilience

to Natural or Man Made factors – Flooding, power availability, political stability

Improve Regulation

, Data Protection or Data Security,

– Less surface areas exposed to attack

A Data Centre Migration is a huge undertaking

Your IT systems need to be up-and-running 24 x 7

Unplanned and extended outages are out of the question

You must reduce risk to the absolute minimum however: – Lift & Shift, Upgraded Infrastructure, Consolidated

Infrastructure, Platform Migration?

Oracle Upgrade, As-Is or Transformational Migration?

What is the Data Centre Migration Centre of Excellence?

An IBM global community of experts

With a wealth of migration knowledge and experience

Applying tried-and-tested methodologies that reduce risk

For a range of clients across all industries

Includes the Oracle Migration Factory

Get the Migration to Pay for Itself by Reducing its TCO

Any Migration will cost Money

– Don’t forget about all the testing resources you’ll need – Don’t assume that internal resources are always free – Power, Environment, Management & Space:

• All add to the Total Cost of Ownership

• Are not individually on a downward “cost model”

Infrastructure can be used to pay for the migration

– If you have too much or its old, its costing you more money than it should – Get it sized ‘right’, less OS Support Costs, less Management Costs

– Reduce Oracle licenses required to run the same workload

– Moving platforms during a migration does not add significant risk, can be used to take advantage of technology improvements

Oracle Upgrade Types during Rationalisation

Transformational/Re-implementation Upgrade

Extensive business process remodelling Several new modules are being implemented Significant change management impact to your organisation

Increased complexity requires more focused planning and program management

Typically requires a re-implementation

Functional Upgrade

Leverages technical baseline

Some introduction of new functionality and modules Limited process design focused on new functionality May have some change management impact

De-customisation analysis

Technical Upgrade

Migration of existing Oracle system to the most recent stable version of the

application

Conversion of data

Rigorously tested and validated Mostly a technical effort

A structured Data Centre Migration Method reduces risk

The IBM method consists of a full-lifecycle approach of six stages Initiation, Discovery, Design, Build, Execute, Close

Our proven and repeatable approach leverages lessons learned and local best practice

It considers a range of issues defined in 5 ‘towers’ – Business, Applications, Technology, Operations and People

There are over 50 specific activity groups, further broken down into hundreds of tasks

–Pic & Mix Approach to Activity Groups & Tasks The method is based on years of experience in planning, managing and performing data

Stage A: Initiation

To get it right first time, data centre migration requires significant and dedicated resources. It must be the core mission – not just a side project Ensuring everyone involved has a clear understanding of the programme objectives from beginning to end is crucial

The Programme Definition Document provides a single reference point

1. Guiding principles steer the decision-making framework

2. Risk Assumptions Issues Dependencies (RAID) analysis covers control and mitigation

3. Baseline discovery data defines the programme scope in terms of assets to migrate

4. Organisational breakdown structure identifies how people will be organised and their

responsibilities

5. Work Breakdown Structure allocates the work to the teams

When faced with the design and

planning challenge of a complex

data centre migration project, it is

vital to work from a common,

(14)

Stage B: High level Discovery and Planning

With any data centre migration, a single version of the truth should be the goal for all baseline data: hardware, software, application information, interfaces, middleware, shared

services, support

IBM’s Discovery Data Model is specifically designed for the entire lifecycle of a data centre migration

Stage C: Detailed Discovery and Design

A Migration Architecture is the technology, method, process and procedures chosen to migrate the applications and data

Many factors shape the detailed plan – either enablers or constraints

Hidden constraints within the business must be fully understood and the business must be engaged early on in the design stage

Early key decisions must be made around the: • Migration approach

• Test strategy

• Approach to networking

These decisions must be fact-based and will shape the migration strategy and architecture.

(16)

Stage D: Build and Test

‘Build’ is the process that establishes the technology foundations for the job, including:

Data centre fabric – buildings, halls, partitions, cages, space, power and cooling

Physical equipment – racking, structured network cabling, fibres, power distribution and outlets

Production WAN and target data centre LAN – WAN and Internet connections, LAN switches, security stacks – firewalls/DMZs/appliances

Migration facility – temporary network links, boundary controls for ‘test bubbles’, etc

Tooling and automation – for the migration of images and data

Stage D: Build and Test continued

(18)

Stage E: Plan and Execute Migrations

In the run up to a migration event (T- 8 weeks), it is critical to run testing to ensure that the infrastructure is ready

Just like any major performance, rehearsals are the key to success

There may be several ‘migration events’ which take place out of hours. Careful resource management is vital to avoid ‘burn out’. An ‘add to the day job’ approach just doesn’t work
