    Virtualization: A Case Study from the IT Trenches - Darren Schoen, Broward Center for the Performing Arts Virtualization: A Case Study from the IT Trenches - Darren Schoen, Broward Center for the Performing Arts Presentation Transcript

    • Red Riders and Pink Nightmares: A Journey into Virtualization.
      Darren Schoen
      Director of Technology Infrastructure, Broward Center for the Performing Arts
    • First Things First….
    • Did you say Virtualization????
    • Red Ryders=Awesome
    • Pink Nightmare =
      Not so Awesome
    • Business Need
      • Employees at Remote Location
      • On Separate Network that had stringent
      security.
      • Able to get to Internet
      • Cheap
      • Needed BCPA internal network access
    • Solution(s)!
      • Remote Access Solved (GoToMyPC)
      • Buy each employee PC and set up in
      vacant Cube (not cost effective)
      • VIRTUALIZATION!
    • What about this Virtualization?
      • Density, Density, Density
      • Ease of Administration
      • Cost Effectiveness
      • Best use of hardware
    • Tastiness
      Amount of Bacon
    • Amount of Savings
      Density of VMs in Environment
    • Vendors We Looked At
      • XenServer (Citrix)
      • VMWare ESX 3.5
      • Microsoft (Not Hyper-V at that time)
      • Virtual Iron (Xen Based)
    • Basis of Comparison
      • Ease of Implementation
      • Support Structure (Online and by Company)
      • Price
      • Scalability
      • Product Maturity
    • Results
    • Conclusion
    • Bacon
    • Why?
      • Online Support Community
      • Maturity of Product (It’s bulletproof!)
      • Scalability
      • Transparent Page Sharing
      • Memory Overcommit
      • Memory Overcommit
      • Memory Overcommit!!
    • Amount of Savings
      Density of VMs in Environment
    • My Roadmap
    • The Joys of ESX Implementation
      • Red Ryders:
      • Ease of Installation
      • Stability
      • Migration of current VM objects
      • Pink Nightmares:
      • Hardware, Hardware, Hardware
      • Licensing, Licensing, Licensing
    • The Story, Just After Implementation
      • 1 Stand-Alone ESXi 3.5 VMWare Box w/2TB+ storage.
      • 16GB RAM, Dual Quad-Core Procs.
      • Total of 10 VMs (not close to being maxed out)
      • Managed as a stand-alone box, no cloning or migration.
      • All Windows XP OS VMs
      • All used as ‘desktops’ for remote users connecting by GoToMyPC
      • No Backup scheme implemented
      • Total Spent: ~$3500…approximately $350 per VM.
      • Total Savings up to this point: $3000.
    • The Story, 2yrs later….
      • 4 Stand-Alone ESXi Boxes, each with 2TB+ internal storage
      • Total of 63 VMs (not maxed out by a longshot)
      • Minimum of 42 VMs on at any given time
      • Managed by Vcenter
      • Scheduled tasks to clone mission critical VMs to different VM host on separate partition.
      • Backup SW on each server VM
      • VM objects include:
      • Exchange Servers
      • SQL Servers
      • Application/Web Servers
      • Workstations
      • Total Spent: ~$30,000..about $476.70 per VM
      • Approximate Savings: ~$75,000
    • What about Hyper-V?
      • Overhead
      • From our experience, more than VMWare
      • Even ‘bare-metal’ install uses most of Server 2008 install files
      • Performance
      • No Transparent Page Sharing
      • No Simultaneous Live Migration
      • No Memory Overcommit!
    • Final Thoughts
      • Bottom Line (based on my first hand experience):
      • You don’t need to spend $50,000 to get a robust Virtual Environment, you can start with 10% of that.
      • For any Mission Critical Application, VMWare is the only solution that I would feel comfortable implementing
    • Questions?
