The XO School server, or XS, is one of the products of the OLPC project, designed to complement the XO laptop. 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.

Design Documents

The high-level design of the School server is described here - note that some may be slightly outdated:

• Scenario taxonomy School Server and XO laptop scenario taxonomy
• The Server Specification introduces the School Server and its functions
• School Service Names

Blueprints

In development

• Lease and update server
• OTP Root Passwords

Implemented

• Datastore Simple Backup and Restore

Key tools

• Ds-backup - backup infrastructure
• XS-rsync - the rsync publishing, used for XO OS updates.
• XS-tools - grabbag of useful utilities. The NOC team will also want this :-)
• XS Automount triggers - used by Xs-activation, Xs-activity-server, Xs-rsync and probably others.
• XS-activation - activation lease server.
• XS-activity-server - serves packages over http.
