  1. ICT Strategy Data Centre Virtualisation

  2. Proposed To-Be Architecture

  3. 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

  4. 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

  5. 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’

  6. VMware Infrastructure Enterprise Virtualisation Virtual Machines Virtual Machines ESX Server ESX Server ESX Server ESX Server ESX Server ESX Server ESX Server ESX Server Server Server Farm Network Storage Server Virtualisation (Example) • 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.

  7. 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

  8. 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

  9. 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)

  10. As-Is Architecture and Roadmap

  11. 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

  12. 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
