6. School Server
Part of our deployment model is to utilize school servers. These servers are designed to provide a gateway to the Internet, a local content repository, back-up, school management, etc. As important as all of these services, their most critical role is to scale the local-area network. Without a school server, the largest network that can be maintained is approximately 20 laptops. Each school server can maintain a network of approximately 120 laptops.
The reasons for this difference include:
- By maintaining state information, the school server eliminates the need for much of the multicast traffic, which puts a heavy load in the network
- The school server can unify up to three separate mesh channels.
We are working towards allowing a laptop to serve the role of the School Server for small schools; but that goal has not been reached yet and so it is not currently an option.
Note: the numbers of machines supported in each network configuration are in flux at the moment. Consult with the OLPC developer team [how?] for up-to-date information.
Please consider the table below when making your deployment plans.
