3. One response to this tension is to have students share a workstation and work together or take turns performing the lab exercises but when forced to make that compromise Dell knows from learner feedback that the customer experience is reduced Also the effectiveness of the training is likely reduced Dell needed to be able to deliver training on Dell Solution offerings of OpenStack and Hadoop In order to replicate the minimal configuration of each solution s reference architecture Dell needed to have at least six systems and one or more network switches in each lab station Additionally each reference architecture calls for different server models and for PowerEdge C Series servers which is often not as suitable for use in other training To provide each pair of students in a class size of 8 with a lab station to share requires 24 servers 48 if strictly following the reference architectures for those two solutions These numbers reflect one implementation which has to have remote access for classes in other regions You have to double those server numbers if Dell wants to provide individual lab stations for each student Once Dell assembles this infrastructure you can remotely access the infrastructure for classes in other regions but it requires an administrative presence in the physical location in case the servers need attention Many instructors have a strong preference for physical access to their class infrastructure in ca
