Case Study | Drake University Taking High-End Graphics Beyond The Lab Adding NVIDIA GRID™ technology with Citrix XenApp virtual application delivery shortened GIS projects and enhanced student learning and engagement at Drake University. Drake University and Citrix Citrix.com 1 NVIDIA GRID technology brings Esri ArcGIS into the field, allowing students to capture and analyze data in real time without having to return to the campus. Drake University is a mid-sized private and Public Administration uses basic office university located in Des Moines, Iowa. Since applications and other tools (mainly financial its founding in 1881, the university has provided and statistical) that don’t require graphics an exceptional learning environment that acceleration. Second, Law School students prepares students for meaningful personal lives, engage clients for tax preparation and had professional accomplishments, and responsible to share a single desktop PC-a cumbersome global citizenship. The current student body arrangement that required clients to come includes more than 3,300 undergraduates to the campus with careful scheduling to pursuing over 70 majors, minors, and avoid conflicts. Third, the Office of Alumni concentrations. An additional 1,700 graduate and Development needs access to Windows 7 students are working toward more than 20 desktops for accessing call center and other graduate degrees offered through six colleges office applications. Finally, students enrolled in and schools. GIS and field ecology classes need access to Esri ArcGIS, which requires graphics Challenge acceleration in order to function properly. Like most colleges, Drake University includes “I use ArcGIS in two primary ways,” explained several large computer labs equipped with Keith Summerville, Professor of Environmental traditional desktop PCs. The increasing need Science and Associate Dean of the College for access to computing resources required of Arts and Sciences at Drake. “First, it is the ever-larger spaces for labs, and the additional primary teaching tool for a yearlong course in computers required increased IT support for GIS. Second, it is an important component of maintenance and upgrades. Further, the existing our field ecology courses and research.

They then reached out to virtualization the performance they needed, and the solutions provider Choice Solutions, which university went ahead with the deployment.” specializes in solving complex virtualization challenges. The virtualization deployment consists of two Dell PowerEdge R720 servers with 256GB of “We visited the university to assess their needs RAM and a single NVIDIA GRID K2 card per and see how best to implement virtualization server.
