School server
The School Server is one of the products of the OLPC project, designed to complement the XO. It is a Linux-based OS (a Fedora-based distribution) engineered to be installed on generic low-end servers. We outline hardware recommendations and in the future, we may offer a hardware platform specially designed for the role.
When we deploy one laptop per child, we must also provide additional infrastructure extending the capabilities of the laptops. While the laptops are self-sufficient for many learning activities, other activities and services depend on the School Server providing connectivity, shared resources and services. Services, tools and activities running on the School Server allow asynchronous interaction, can use larger storage capacity, and take advantage of the processing power of the XS.
Outside of collaboration activities, the School Server provides other services to the laptops -- those services are transparent, seamless and automagic. Read more about the high level definition of the School Server.
