The document discusses strategies for transforming IT services, including updating hardware/software, relocating data centers, and adopting new technologies. It outlines a 5-phase methodology for successful transformations, covering requirements definition, research, planning, implementation, and post-implementation. The document also discusses specific challenges that can arise when migrating NonStop systems between data centers.
IT Service Transformations
- 1. IT Service Transformations 20th July 2011 The smart choice for IT services and support of systems that cannot afford to fail! Copyright © TCM Solutions Limited 2011. All Rights Reserved.
- 2. Today’s Share – what’s in a word? Transformation • Updates to hardware/software • Technology – steps and leaps • Upgrades to hardware/software • Data centre relocation • New technology Make IT Better, Faster, Cheaper
- 3. Ingredients to Transformation Success • Team • Business, IT, PMO, Operations all play important roles • Clear roles and responsibilities are crucial – ‘The Buck’ stops where? • Right skillset at the right time • Culture • Change Leadership and Management is way of life • Focus on continuous ROI improvement • Goals and objectives clear • Processes • Repeatable Methodology • Communications and reporting • Measures/Outputs clear and unambiguous
- 4. Transformation Methodology and Framework A documented and phased methodology Planning and execution framework is flexible enough for projects of any size or complexity Experiential – YES - but open to new ideas Continually updated to reflect emerging risks and ways of working It becomes YOUR methodology Definition of Requirements Phase Research and Data Gathering Phase Planning Phase Implementation Phase Post-Implementation Phase
- 5. Phase 1: Definition of Requirements • Determine and agree Scope - clear definition of requirements • Determine overall project objective • Identify business drivers • Timelines and high-level milestones • Change control • Risk Management process • Project reporting (reports, meetings etc.) • Communications plan – how, what, and when to communicate Key inputs: Business/Stakeholder/IT Requirements Key Outputs: Draft Project Overview Document –project bible from inception to steady state 3rd Party SOW and Commercials Risk Register
- 6. Phase 2: Research and Data Gathering • Determine and Document Complete infrastructure NonStop platform specific Storage (internal, ESS) Backup (Tape Silo, VTS, Other) Other platforms Applications (end-to-end, dependencies, interfaces) Network (TCP/IP, SNA, ICE etc.) Business Requirements – co-existing Obtain and understand existing DR Procedures Key inputs: Existing application/operational documentation Workshops/Interviews with key application/platform staff Key Outputs: Detailed findings report High-level Project Plan and updated Project Overview Risk Register
- 7. Phase 3: Planning • Develop & present detailed Transformation Implementation plan • Agree timescales, responsibilities, ownership • Determine platform transformation strategy: Seed HW, Lift and Shift, Logical (Data/Application/Workload Switch) or combinations of above • Logistics: Site Surveys, Security, Compliance, Communication and Notification • Develop Test Plans/Scripts, Swing/Switch Procedures, Contingency & Backout Procedures Key inputs: Output from Previous Phases (Project Overview, Findings, High-level Plan) Key Outputs: Detailed Project Plan; ‘Move’ timeline plan(s) Technical Solution Document Test Plans/Scripts (infrastructure, Network, Swing/Switch, Application) Site Plan(s) Risk Register
- 8. Phase 4: Implementation • Team assigned and assembled • Risk identified, assessed, mitigated and/or accepted • Seed HW Installed and Prepared (if seed approach) • Testing: Unit, System, Network, Application/DB build • Platform/Application/Data Migrated • Full user testing/commissioning • Any new solutions implemented (if required e.g. new Tape Backup solution) Key inputs: Detailed Implementation Plan; Site Plan(s) Technical Solution Document Test Plans/Scripts Key Outputs: Completed Test Scripts results System/Application/Data Migrated (‘moved’) Service Restored/Live
- 9. Phase 5: Post-Implementation • Documentation Updated (DR Plans, Operational Documentation) • ‘Parallel’ Support – Transition to Steady State • Project Completion business acceptance • Lessons Learned and Feedback • Feedback and Lessons Learned Insight recombined into Methodology Framework Key inputs: Existing Operational procedure documentation Key Outputs: Updated Operational Documentation Project completion acceptance Lessons Learned Documented Insight published to all stakeholders
- 10. Specific DCM NonStop Migration Strategies What possible migration strategies can you deploy? 1. Seed Equipment • Procure/loan additional NonStop equipment and SW license to be located in Target DC and built to mirror existing environment • Pros • Easy backout • Extensive testing possible • Allows “bedding in” time for all hardware components • Potential for twin-tail maintenance of data • Cons • Cost – HW procurement and SW licensing • Additional maintenance required (initial population vs. live)
- 11. Specific DCM NonStop Migration Strategies (cont.) 2. Lift and Shift • Pre-build network and environmental requirements in Target DC then de-install equipment and physically move to Target DC • Pros • Less cost • Reduced setup and license issues • No maintenance duplication • Cons • Higher Risk • Limited testing • Protracted outage and potentially lengthy outage required • Extended backout/recovery
- 12. Specific DCM NonStop Migration Strategies (cont.) 3. Workload Switch / Combination • Utilise NonStop estate to transfer workload between systems (allows individual lift and shift of each NonStop system if required) • Pros • Less risk than Lift and Shift – no data ‘physically’ moves! • Full testing possible on relocated equipment • Cons • Existing NonStop estate may not have sufficient capacity • “settle-in” time for relocated equipment to reduce failures • Configuration and/or physical DC location may not allow
- 13. NonStop Migration ‘real world’ Challenges • Planned outages Planned outages of dependent infrastructure may delay your NonStop move • Licensing If using seed HW, don’t forget to factor in ‘temporary’ NonStop SW license costs – hp and 3rd parties • Peripheral devices e.g. Tape Silos’ not moving – may result in new Backup Solution to be sought and implemented • Shared Equipment E.g. ESS storage shared by NonStop and other platforms – can both move at same time? • Business Constraints E.g. Absolutely no data loss; No Data to be physically moved – may need to look at migration from Internal to ESS storage to fulfill requirement
- 14. NonStop Migration ‘real world’ Challenges • Software Version Currency Is Target system running same versions of OS, SPR’s and 3rd Party software levels? • Power Requirements Does the Target DC have same power connections/requirements as source DC? • Network Latency How far away is Target DC? Will Network performance be an issue? (e.g. DWDM Links) • Timescales Will you incur penalties if you don’t vacate existing DC by a specific date? • Data Centre Accessibility constraints How easy is it to get the equipment out of the existing DC? Any size, weight, or location limitations to overcome?
- 15. Summary • Understand and communicate objectives • Follow a well-defined transformation project methodology • Research and Data Gathering – Understand Application end-to-end and dependencies • Plan strategy – Seed, Lift & Shift, Workload switch – determined by Risks vs. Costs / Service outage limits etc. • Create detailed step-by-step plan, incl. resource allocation and milestones • Implement per plan – call ‘audibles’ when necessary • Operational Documentation Updates / ‘Parallel’ Support • DR/BCP Procedure Plan updates / Tests • Lessons learned – important for future projects
