  1. Building a 21st Century Virtualized Enterprise Architecture Dr. Zafar Chaudry, MD, MSc, MIS, MBCS, CITP Director of IM&T 31 October 2007

  2. Highlights • Who Are We? • Healthcare Challenges • IT Challenges • What Did We Find? • Our Existing Infrastructure • Our Strategy • Virtualized, SAN attached Infrastructure • Data Replication / Information Lifecycle Management • What Did We Get? • VM Lessons

  3. Who Are We? • Europe’s Largest Women’s Provider • Europe’s Largest Neonatology Unit • Europe’s Largest Genetics Laboratory • £80 million turnover ($160 / €112 million) • £3 million ($6 / €4.2 million) on IT • 1,600 employees – 5 sites • Ranked 8th in UK (out of 270+) • IT & IS Technical Team of 12 (total: 60 WTE) • Delivered 8,000 Babies • Performed 11,000 Operations • Performed 900 IVF Cycles • Foundation Trust – “independent business” • Rated “Excellent” for “Quality of Services” & “Use of Resources” by Healthcare Commission

  4. Healthcare Challenges Increasing Costs Increasing Demand Clinician Shortages Increasing Litigation Increasing Medical Errors Limited IT Budgets Adopting New Technology Limited Hospital IT Skills Healthcare Patient Data Privacy Legislation Increasing Audit Requirements

  5. The Mounting Pressure on IT 4. Complexity Rising - Number of Devices, connections, tools, etc. Impact Areas: - Bus. Intelligence - Technology - Bus. Continuity - Backup, Recovery AND Archive - Compliance - Content Management Managing Growth 3. Info Governance & Compliance Increasing - Have to keep info LONGER 2. User Expectations are Growing - Always available, more capabilities 1. Info growing 3X/yr The Only Things Not Growing: Time, Staff and Budget! - Content is growing fastest

  6. Health Information: Unstructured Data Growth More growth: Health Information stored on disk arrays grew200%+ in 2006 More uses: EPR, PACS, Collaboration, Knowledge Management, Data Analytics Informationgrowth Information uses Information regulations More regulations: Healthcare Information Retention, E-mail Retention Information More types: Financial Clinical Operational Quality Imaging Information types

  7. What Did We Find? • Server “sprawl” • PCs used as servers everywhere – under desks, in cupboards • Novell Domain & GroupWise • Data Everywhere • Data held on PCs, floppy discs, not backed up • Data that is backed up is on tape (costs ballooning; tapes accumulating) • Data not archived • Data deleted e.g. e-mail deleted by users • No E-mail retention • Data “sprawl” • Demand for new Applications & Data Storage increasing exponentially • Clinical Records retention: 8 yrs for Gynae / 25 yrs for OB

  8. April 2005 Infrastructure

  9. Our Strategy – “Adaptive Enterprise” Simplification: data / systems / infrastructure for easier centralised management Standardisation: systems / servers / business processes Virtualisation: systems / teams / hardware Automation: reduce manual working

  10. January 2007 Infrastructure

  11. Data Replication / ILM

  12. DNS/DHCP WM Server Win2K AS SQL Server Call for Upgrade What Did Virtualisation Give Us? • New server commissioning in 10 minutes ESX Server 1 ESX Server 2 ESX Server 3

  13. DNS/DHCP WM Server Win2K AS WM Server SQL Server SQL Server Call for Upgrade What Did Virtualisation Give Us? • New server commissioning in 10 minutes • Ability to move • Servers in “real-time” ESX Server 1 ESX Server 2 ESX Server 3

  14. Always Powered On DNS/DHCP Win2K AS WM Server SQL Server Powered Off for Upgrade What Did Virtualisation Give Us? • New server commissioning in 10 minutes • Ability to move servers in “real-time” • Zero downtime maintenance of physical server hardware ESX Server 1 ESX Server 2 ESX Server 3

  15. DNS/DHCP WM Server Win2K AS WM Server SQL Server SQL Server  Upgrade Finished Powered On Again What Did Virtualisation Give Us? • New server commissioning in 10 minutes • Ability to move • Servers in “real-time” • Zero downtime maintenance of physical server hardware ESX Server 1 ESX Server 2 ESX Server 3

  16. Next Generation – Jan 2008 – VI3

  17. What Did We Get? • Simplified infrastructure • Server Consolidation • Server standardisation (Windows 2003 platform) • Virtualisation (VMWare ESX 2.5.2) • Ability to use less hardware • Consolidation of 8:1 • Power savings of 80% • Storage Consolidation (EMC Clariion CX 500) • Data Protection (Full DR – Clariion CX500) • Data Value Classification: Information Lifecycle Management (tiered data) • Optimised storage • File age, type, size, access, availability, usage, age, recovery – FC / SATA • Capacity Expansion from 500GB to 6.5TB FC & 22.5TB SATA

  18. VMWare Lessons • Be careful of the consolidation ratio • Watch out for Microsoft licenses: • 1 Enterprise per 4 VMs • 1 SQL Server per processor • Costly • Cost can quickly skyrocket – VM licenses aren’t the cheapest • Training – knowledge transfer • Hardware needs to have dual processors • Hardware needs a lot of RAM (12GB min) • Right partner – as expertise in area is a problem • Certain applications will not virtualise • VMotion only works across servers with same generation processors – could end up with multiple clusters (VM “sprawl”) • Evaluate sub-contractors carefully – check VMware certifications
