ICT Strategy

Data Centre Virtualisation

Proposed To-Be Architecture

Single Virtual Data Centre

• Delivered as a “Metro” Cluster across [at least] two geographically separate locations

• Cluster Interconnect via resilient NRTS CWDM• Fibre-Channel SAN

Universal Access

• The 3 C’s:• Centralisation• Consolidation• Convergence

• Location transparency• Independent of Agency’s

organisational structures• ‘Martini’ virtualised access:

• Any Time• Any Place• Anywhere

• Resilient/Disaster Tolerant• No Single Point of Failure• Business Continuity

Server Consolidation

• Server sprawl:• Adding dedicated servers for new projects• Growth in capacity especially data storage

• Inefficiencies – low utilisation of individual servers• Rising costs and increased carbon footprint:

• Cost of managing lots of servers• Cost of power now exceeds the cost of the server

(system fans are biggest drain)• ….• Resulting trend is towards consolidated ‘server farms’

Storage

• Partition CPU and memory in multiple virtual machines

• Store virtual machine disks on local or shared storage. VMFS cluster file system manages virtual machine disk storage

• Build networks within or across ESX Servers.

Modular Data Centres

• 21st Century Data Centres now focus on power (watts/sq. metre) as most critical factors in design

• Implements densely packed commodity clusters• Utilises macro-modules based on standard shipping

containers for ease of transport• Modular building blocks• Extends the idea of blade servers• Improved efficiency• Addresses “Green” issues• Implement via Managed Service contract

Drivers/Benefits• Greening Government ICT:

• Carbon Neutral (12.5% reduction) by 2012

• 20% carbon reduction by 2020

• Sustainable Operations of the Government Estate (SOGE)

• HA Sustainable Development Action Plan

• CO2 and cost reduction

• Increased organisational flexibility

• Enhanced Business Continuity

Relationship to SOA

• Supports the trend towards Everything as a Service• Communication as a Service (CaaS)

• Infrastructure as a Service (IaaS)

• Software as a Service (SaaS)

• Data as a Service (DaaS)

• Platform as a Service (PaaS)

• Also the trend towards “Cloud” Computing (next step from the grid-utility model)

As-Is Architecture and Roadmap

Current Scenario• Existing Data Centres:

• Operational:• Coleshill

• Westhoughton

• Partial Disaster Recovery

• Business (Atos Origin):• Andover (Main Centre)

• Birmingham (Test/DR Centre)

• Additional application servers located in:• NTCC

• RCC’s

• HA Offices – all migrated to Atos by June ‘09

Roadmap

• ICT Service Transformation is a step in the right direction (but only BSS Domain)

• Need to extend into OSS Domain via:• TI2011+

• Technology Convergence

• IAM

• Technology Refresh

• New Managed Service contracts
