  1. Re-thinking infrastructure Unassuming Assumptions Mike Daigle Ramon Kagan Ian Lumb Charles Porter

  2. Agenda • Background • Where we were • Desires • New issues • Proposed solution • Where we are • Lessons learned • Future considerations

  3. Background

  4. 65+ servers coming in - 2nd year of full refresh • Previous year was painful • Showed our bottlenecks and process setbacks • New central NAS/SAN coming same time • Tried and tested ways were antiquated • Racking, cable management, OS builds • Heating and power concerns taking increasing priority

  5. Where we were

  6. Console Network YorkU Data Network Public IPs

  7. Data Centre Star Topology

  8. Desires

  9. 1 Storage Management 10 Console

  10. What Not To Do…

  11. What Not To Do…

  12. Infrastructure Operations Objectives

  13. New Issues

  14. Firewall VLAN Storage VLAN Console Service VLAN

  15. What Not To Do…

  16. 12 Kw per rack

  17. Proposed Solution

  18. Subset of the data centre

  19. of Management Storage Service 1 2

  20. Console Network Management Network Private IPs YorkU Data Network Public IPs Ethernet SAN Private IPs

  21. Where We Are

  22. Service/Storage 1

  23. Lessons Learned

  24. Other Lessons Learned • Discipline and change management • Sizing is hard to estimate • Budget limits your options and drives alternative decisions and/or plans • Working collaboratively can work!

  25. Future Considerations

  26. Image/PXE/net booting for Windows, Solaris x64 and maybe others • Physical separation of the service/storage • Migration may be painful but a result of budget limitations • 10GigE and jumbo frames on the storage network
