The Center for the Study of Digital Libraries uses and maintains over 100 computer systems spanning a myriad array of hardware and software platforms. These computers are situated within 14 offices, 4 large shared office spaces, 2 laboratories, and a conference room on the main campus of Texas A&M University in College Station, Texas. Connectivity to these systems consists of a gigabit Ethernet network connected to the University’s backbone. Wireless network access is also available to users within the Center. 44 Multiprocessor Linux servers provide Linux services including a 12 node Beowulf cluster, 3 dedicated web application development and hosting machines, and two interactive access machines for application development. 23 of the servers are dedicated to individual projects. Two shared disk clusters with multi-terabyte storage capacity serves Windows as well as Unix users. Roughly 15% of desktop workstations run some variant of Unix, with the remainder largely consisting of Windows systems. Server systems are routinely backed up over the network to a multi-tape DAT backup unit and a 1.5TB file server dedicated to backups. To aid in system testing, the CSDL maintains a testbed providing all popular Web browsers on Windows, Linux, and Macintosh. Additionally, the center has a five head Linux-based user study lab. The Center also has a dedicated state-of-the-art conference room equipped with a SMART Board connected to a computer with digital projection equipment. Additionally a second machine attached to a flat display television and digital video camera provide videoconferencing support. Wired as well as wireless Internet access is available to meeting participants.
