Unix Servers v SIRSI Unicorn library automation system v Library Web Server for Public resources v SilverPlatter ERL Server v OCLC SiteSearch resources v Development and test environment

Library Networks v Ethernet for building LANs v Older networks using 10Base2 (ThinWire) Ethernet –Coaxial RG-58 cable in bus topology –All will be converted to 10BaseT in next 2 years v Newer networks use 10BaseT –Category 5 or Category 6 UTP

Network Communications v 10Base2 networks use DEC DEMPR (Digital Ethernet MultiPort Repeater) –10 to 30 stations per Segment –8 Segments / DEMPR v Each DEMPR connects to a Switched Ethernet port on a FORE PowerHub v Each PowerHub connects to campus backbone via ATM

Network Communications v 10BaseT Networks use HP Ethernet Hubs –SNMP Managed –Security enhancements such as data scribbling to non-destination ports –10mb/sec shared Ethernet v Each hub connects to switched Ethernet port on PowerHub v PowerHub connects to ATM network

Network Communications v Servers connect directly to switched Ethernet ports on PowerHubs –Currently 10mb/sec –Plan to increase to 100mb/sec

Desktop Computing v 400+ Desktop Computers –All but 40 Pentium based v Windows NT 4.0 operating environment v Novell IntranetWare Client v Novell Application Launcher v Most applications loaded from servers

Campus Backbone Architecture v ATM Backbone v FORE PowerHubs v Fiber Optic Network –Distributed Star Topoloty –Multiple Fiber Distribution Centers v Switched Ethernet in Buildings v Shared Ethernet for most LANs
