  1. Proposed Data Centre and base Infrastructure access strategy John Young & Jon Blake May 2007

  2. Questions for IMC members • Does the approach to DR outlined here cover your needs? • Can you prioritise your systems into Gold, Silver and Bronze categories and specify critical periods? • Can you make the case for investment to cover the selected level of Gold, Silver, Bronze rating, if not what would be the impact of a loss of service e.g. Bronze level ? • Can you endorse this approach, noting the base resilience / Disaster Recovery actions?

  3. Contents Background and issues Principles Two-phase approach Current and planned network and datacentre layout Data centre sourcing options Benefits Three-tier DR approach Base infrastructure actions and impacts Summary Required actions

  4. Background • ONS has 5 Data Centres (inc. Siemens) plus 2 server rooms, with different states of • security, • capacity • appropriateness • The March 2007 Capability review identified significant risks in • DR • Data Centre infrastructure • DR capability • limited to external site DR for the PPI and RSI systems on NUMA, and Model 204. • Can only be accessed from service suppliers premises • Other systems protection limited to tape backup • Odyssey requirement unspecified • Odyssey capacity requirements need to be determined • We need to find a solution to these complex issues and propose a two phase approach • Phase 1: Base Infrastructure • Phase 2: Modernised System Requirements

  5. Proposed Principles • Resilience • to provide appropriate availability across ONS • Disaster Recovery Capability • appropriate to ONS business needs • Good VFM for ONS balancing costs versus risks • Simplify the deployment of equipment taking a shared holistic approach • Resolve areas of weakness i.e. • Data Centre environments and protection • Remote Access Support access and reslience • Firewall security • GSI network access(currently 1 very busy link) for mail and internet

  6. Phase 1: Base Infrastructure Consists of:datacentres networks, external connectivity Objectives • provide a logical design which can support Disaster Recovery requirements as they are determined for each business application • identify gaps and weaknesses in the capability of the base infrastructure to support ONS systems and the means to communicate with them • identify options to implement the logical solution

  7. Phase 2: Modernised System requirements A joint Odyssey / IM activity Objectives • Identify the capacity requirements of the Odyssey systems (including Atlas) for the next 3 years • Obtain the performance, service level and DR requirements of each of these systems from the business • Propose technical designs (including costs) which satisfy the above • Subsequently establish a migration plan in conjunction with Phase 1 to realise the approach

WAN Siemens Data Centre Today- physical Newport Drummond Gate Newport Data Centre London Data Centre • Closing • No fire protection • Poor environment • No power backup Myddleton St Titchfield CardiffBay Data Centre Titchfield Data Centre • Lacks expansion • Equipment proximity • Excellent power and environment Backed-up WAN link • Limited space • No fire protection • Adequate power protection Back-up WAN Link (Non active) WAN Link – no back-up Direct link

  14. Permutations of the above

  15. Benefits • Logical Data Centre and DR service approach provides • Predetermined DR service models for developers to use propose and develop solutions tailored to business needs • Framework against which physical Data Centre solutions can be established and reviewed • Standardised framework with potential economies of scale • Economies of scale for equipment and operation • Clarity of management

  16. Illustrative 3 Tier DR approach Silver Gold Bronze

  17. Business evaluation of DR requirements • ONS needs: • a common process across businesses; • a single body to prioritise DR requirements. Example Method • Financial and Reputational impact assessed on a 1-5 scale for each period • e.g. recovering Process 1 in less than 24 hours could have a low Financial and reputational impact, but within 48 hours would begin to have adverse affects, at 72 hours would be more damaging, and 5 or 7 days is unacceptable.

  19. Base infrastructure actions and impacts

  20. Summary • ONS DR facilities are extremely limited and requirements are not established • ONS Data Centre capability is fragmented and ranges from very poor to excellent in its capability • ONS other base infrastructure is reasonably sound, however it requires additional resilience and capacity to be installed, e.g. RAS, GSI, WAN links • A logical model to rationalise this is proposed • A 2nd piece of work is in hand to determine the Odyssey requirements (inc. Atlas) • Further work is urgently required for NUMA based services to consider such systems as RPI and CSDB • Several Data Centre sourcing options are proposed for investigation

  21. Required Actions • IMC • Confirm the strategy provides a basis to support their business objectives and risk management needs • Members arrange the provision of the necessary input information about the business needs in their areas • Support is given for a project to establish the respective Data Centre cost evaluations and selection • Note that projects will be brought forward to NWEB to realise …. • EMG • Note and endorse this proposal if supported by IMC
