Hi from a small island in the north Pacific - Kosrae (FSM). Here they are going for a complete programme with all graders 1 to 8 . That takes in six Elementary Schools (the US system is used here) the largest has 3 streams, 24 classes and about 500 students. The school is arranged in a large U plan form in two floors/storeys.
What experience do we have on the latest thinking about the capacity of a single server? Here in Kosrae they have good 24/7 power availability and air-conditioned offices in five of the schools. We can therefore specify powerful machines, even dedicated server models if need be. If we segregate off each of the 24 class groups, would a single powerful machine server be able to handle 500 students in 24 classes (courses) simultaneously? (of course in practice that maximum load will rarely occur). I suspect we don't have a definitive answer and I would like to develop a strategy with the ICT people here. Perhaps to plan for multiple servers in such a school and then progressively introduce them in response to the way they perform. Any feedback on good techniques or references/guidance on the wireless infrastructure would also be appreciated. In the larger school, we have two floors, 12 classrooms per floor, in U-shape layout. I would place one AP per classroom spread evenly around the school - that would be about 20 students per AP. The APs set up all on eth1 LAN with the same SSID. If we use multiple servers, we'd use different SSIDs for each. I have not deployed such a large site before so any comments on this would be appreciated. (2) In PNG SDP's project in North Fly, PNG, we are using small "eboxes" because of the need to run on solar power. We have deployed one full-campus wireless/server installation, quite a small school (160 total, 80 users in the first roll out). These users are divided into 3 class groups, as Moodle courses. So they are segregated. We have had feedback that it still gets slow / congested when all users are on simultaneously (80 users in 3 separate courses). I don't have an opportunity to visit the school and quickly inspect the servers logs etc, so I am not sure of the cauase, i.e. the small capacity of the "ebox" or other cause. Any comments as to what to check would be appreciated David Leeming
