Depending on the Chromebook throughput desired, one Go-Box per 2,000 Chromebooks to be provisioned is a general ratio used by our customers with normal IT resources. Where thin IT staffing/resources exist, a ratio of one Go-Box per 500 Chromebooks is common.
Alternatively, many customers find more success by assigning 1 Go-Box unit to each IT Technician, so they can conveniently use their own Go-Box for Chromebook deployments and/or re-enrollments at any of the school locations they may be working at each day.
