CACHEBOX circles Chicago

May 30, 2013

ApplianSys announced today the latest in a series of school district customers in the Greater Chicago area stretching back to 2008.  Glenbard High School District #87, in Chicago’s western suburbs, has bought a CACHEBOX solution to help improve the delivery of bandwidth-intensive content for users and kick off its 1:1 student-to-device scheme.

Glenbard’s existing 500Mbps connection currently caters to 3,000-5,000 school-owned devices and over 4,000 student smartphones. With most of the school’s traffic coming from large download / update services, there was over 90% bandwidth utilisation during peak hours, causing slow user browsing speeds. Technology Director Nate Dhamers knew that the school’s existing bandwidth would not be able to cope with the additional strain from the introduction of a 1:1 programme.

To improve browsing speeds and allow students to bring their own devices to school, Glenbard deployed a pair of CACHEBOX310s. The two units are clustered for high availability and redundancy.

Nate explains: “A lot of our network traffic comes from sites like YouTube (over 200GB daily), Apple and Microsoft. Other bandwidth hogs include Carnegie Learning, Read 180, System 44 and Google image searching. Waiting for things to download is extremely frustrating for students and staff.

“One of our biggest concerns right now is handling traffic from appstore applications on iPad. The plan is to roll out our 1:1 program for around 8,500 students, phased over the next 3-4 years. For this to work, we need the kind of transparent and scalable solution that CACHEBOX offers. ”

Glenbard Township High School District 87 (www.glenbard87.org) is based in Glen Ellyn, Illinois and consists of Glenbard South, Glenbard North, Glenbard East, and Glenbard West. It is the third largest school district in Illinois. The term Glenbard is a combination of Glen Ellyn and Lombard, the two predominant towns of the district.
