We replaced our Campus Computer System this March. Our new system has two new features: (1) all services are running in Virtual Machines (VMware vSphere) including DNS, E-Mail, Web, e-Learning, Remote access, File server and Network boot servers. Moreover, each service is provided by more than one guest OS and load balancer, so we can easily to maintain the OS image because the service is still available when one guest OS is shutdown for maintenance. Of course, load balancing is also redundant (active-standby). (2) All our university members' electric Identities are provided from our new system. In addition, several Web-based systems are shibbolized (Web-based Single Sign On system produced by Internet2) such as account management service, e-Learning system and network outlets. Thus, our system consists of only 12 real servers mounted on 4 racks and over 200 PCs are booted from Network boot servers. Moreover, about 5,000 users can use our system and federated systems by integrated Identity service (LDAP, RADIUS, Active Directory and Shibboleth).
