Mail and groupware with Exchange

Every employee of the Heinz Nixdorf Institute receives a mailbox on the IMT's central Exchange server at . Their e-mails are then forwarded directly from the IMT to the Exchange server. The mailbox size is 2 GB.

The Exchange server also offers the option of storing calendars, addresses and e-mails for specific user or project groups, as well as the option of booking resources for meeting rooms, projectors, laboratory equipment or similar.


Central File Service of the Heinz Nixdorf Institute

The central file servers of the Heinz Nixdorf Institute offer all users sufficient space to store the data they need for their work and studies. The data is backed up daily so that important files can be restored at any time in the event of data loss. To avoid a "single point of failure", a separate file server is set up for each larger group. On the one hand, this prevents all employees of the institute from being affected if a file server fails and, on the other hand, if a decentralised file server fails, its data can be made available at relatively short notice by one of the other file servers.

Data from the specialised groups, such as project data, should be stored in the respective group directories on the IMT's Isilon file server.

Furthermore, every user is free to store his personal data (home directory) not on the central file server of the Heinz Nixdorf Institute, but in his personal user directory on the Isilon file server of the IMT.

HNI Network and Systems Administration provides each specialist group with its own subnet. All specialist group servers, workstation computers, printers and laboratory equipment can be integrated into this subnet. The HNI computer centre also provides a cross-institute logical structure, the domain This is where the Windows domain HNIRB, the web server and the email addresses <UserName>@hni.uni-paderborn run.
