Red Riders and Pink Nightmares: A Journey into Virtualization. Darren Schoen Director of Technology Infrastructure, Broward Center for the Performing Arts
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
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
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
