  1. DES Virtualization IPMA Briefing 2012

  2. A New Opportunity - DES Legislative mandate to consolidate 5 agencies into DES Consolidate support to DES and support 2 existing agencies and 1 new agency IT support responsibility includes OFM, Governor’s Office and CTS Challenges abound – disparate storage, duplicate applications, redundant infrastructure, firewall separation

  3. DES at Inception

  4. By the Numbers… • DES as new agency October 1st, 2011 • 345 servers, 63% virtualized • VMware was primary platform • 3 SAN enabled virtual farms

  5. Virtual Objectives Consolidate hardware in single “vFarm” Extend layer 2 to virtualize existing pre-DES agency infrastructures Support “come as you are” vDC to expedite virtualization and consolidation Build new DES branded virtual data center topology for DES services eClient and eApp

  6. Virtual Data Centers…

  7. DES Future Services

  8. Present Virtual Work Virtualize 93 more servers to hit 90% Migrate 3 ESX farms to 1 shared farm Scale to support anticipated Windows server growth of 7 – 10% per year Build out network to support enterprise services and desired efficiency

  9. DES Shared Virtual Platform VMware ESX4i HP DL380 G7 rackable servers RAM (lots of it) EqualLogiciSCSI storage Licensing at the processor level More RAM! * RAM is always limiting factor

  10. Storage iSCSI based 1GB I/F ethernet storage 89.24 TB of RAID50 SAS & SATA disk 16% in near term snapshots Thin provisioned, over provisioned Replicated to TierPoint data center Fully virtualized

  11. Layer 2 Extensions enabled… • Virtualize “in place” – no change for existing applications • Built-in backup / recovery • vRanger immediately picks up new guests • Shared storage scalability • Growth accommodated at multi-agency level • Operational mgmt by designated leads • Spread vFarm mgmt to key leads with appropriate training

  12. Layer 2 “Extended”

  13. Virtual Console • Virtual Console roles • Resource Pool Admin • Resource Pool Server Admin • Attempted “linked consoles” • End client still needs direct access to primary console • Jumpbox model • RDP to console, run locally with pre-DES AD accounts set to virtual Data Centers

  14. VMware Converter • VM converter “needs” • Virtual Console enabled guest within each pre-DES network • Migration host with kernal (ip) on each client network • No affinity during transition to invidual VM host

  15. Security • pre-DES agencies had different security policies and data risks • New security team and unified strategy at DES key enabler • Building to support security spectrum • vLAN separation • vSwitch separation • vFirewall security & audit

  16. Why Virtualize? Story 1 • AFRS Data Warehouse • Problem: Existing DW is operating 2 Windows 2003 x64 servers with SQL Server 2005 and team wants to migrate to Windows 2008 R2 x64 with SQL Server 2008 R2 Enterprise. Migration of data and transition is expected to take in excess of a month. • Server 1: 2.85 TB of storage on 3 SAN volumes F, G, H • Server 2: 1.65 TB of storage on 2 SAN volume F, G

  17. Why Virtualize? Story 2 • ERDC P20 Data Warehouse • Problem: The new P20 Data Warehouse for the Economic Research & Development Council (ERDC) needed the ability to “recover” a full infrastructure platform (QA, DEV, Sandbox or Prod) to any given day / week in recent history.

  18. Lessons Learned Cross train early and often Change management and disciplined approach Keep capacity for maintenance (n+1+ a little more) Script configurations wherever possible for consistency (powershell or ???) Don’t assume – validate throughput, monitor links for even load distribution, etc. (Windows perfmon, VMware esxtop, switch CLI) Don’t underestimate RAM and storage Have your customers tout your success (nothing sells your service more than a happy customer) Patience – build in quality rather than rework
