 ====== OICE IT infrastructure ======
-===== General description =====
 The OICE aims to supply an effective working environment for all its users. A typical workflow is as follows:
@@ Line 17: / Line 15: @@
   - In periodic intervals, currently every night, all data saved via the OMERO framework is backed up to our backup-server (hopefully at the RRZE), so that it can be restored in case of an accidental erase by the user or a massive hard disk failure.
+This workflow is facilitated by a number of IT services mostly hosted on OICE servers. These are
+  * A **central user account database** provided by an LDAP server for managing user authentication with all externally provided OICE services (Wiki, PPMS, NT4 PDC, User DB), \\ hosted on //Romulus//
+  * An **Windows NT4 Primary Domain Controller** (NT4 PDC) for managing central logins on microscope controller PCs running Microsoft Windows and for providing CIFS share drives for users and staff members, \\ hosted on //Romulus//
+  * A **DokuWiki Wikipedia-styled framework** for internal and external dokumentation, such as user regulations, safety regulations, software installation help, etc., \\ hosted on //Romulus//
+  * A **booking system** (PPMS) for devices in the OICE pool, \\ externally hosted by StratoCore, but users are authenticated via the OICE LDAP server
+  * A dedicated high performance (RAID 6 array of 15000 rpm disks) Thecus N16000PRO **storage server** //Remus// directly connected to //Romulus// via iSCSI over 1000Mbps-Ethernet.
+  * A dedicated high capacity **backup server** (RAID 6 array of currently 8 disks holding 8 Terabyte each) //RheaSilvia// holding regular incremental and encrypted backups of all user data.
