Virtual Desktop Infrastructure Duke University Office of Information Technology Common Solutions Group Summer 2012 Evan Levine
Duke Health Technology Services • VMware VDI at Patient Revenue Management Organization and Duke Raleigh Hospital • VDI focus decreasing in a shift to virtual applications • Citrix XenApp use increasing rapidly system wide • Duke Maestro Care (Epic ERP) system will only be available through Citrix virtual application deployment
VDI @ Duke University Today • Central Emphasis on VCL • Limited use of commercial VDI products at various schools
Virtual Computing Lab • Capacity for 300 simultaneous seats • Central and departmentally managed images • Network storage through AFS -> Moving to NAS (CIFS) • Overnight provisioning of machines for HPC to use with Condor jobs • 8 PowerEdge R710 with 2*4 Core CPUs, 72 GB RAM (576 GB Total), vSphere 4.1u1
VCL Spring 2012 Detail • Total Reservations: 5,183 • Total Hours Used: 7,782 • "Now" Reservations: 5,137 • "Later" Reservations: 78 • Load times >= 2 minutes: 383 • Total Unique Users: 775 • Unique Windows 7 Users: 717
Popularity Contest • 1. SolidWorks • 2. OIT Windows Lab • 3. ArcGIS • 4. Stata • 5. Chemistry Course Apps • 6. Nvivo
VCL Challenges Discovered • Fear of Change – VCL requires faculty, staff, and students to do something new • Network – Wireless performance is critical for synchronized use • Storage - Not all software is well suited to running with remote storage • Training – OIT only creates and maintains public computing lab and site-licensed application images
VDI @ Duke University Tomorrow? • Persistent desktops, not just short term reservations and sandbox environments • Centrally run service to ease issues of security, global expansion, travel, and platform independent access • Likely adoption of commercial products from VMware, Citrix, or similar • Virtual application deployment
Anticipated Challenges • People Still Fear Change! • Network – How well is this going to work globally? • Vendors – Compared to VCL, working with VMware and Citrix will feel very inflexible • Will this really simplify anything or reduce cost?
Technologies to Watch • Boomerang – Javascript capable of reporting user network bandwidth, latency, etc. • “noVNC” – Javascript making it possible to embed a VNC remote desktop client in a zero-install HTML5 web page • Virtual GPU solutions
