Title: CS Department Computing Infrastructure

Abstract:

The Princeton University Department of Computer Science has hundreds
of PC/workstations running a variety of operating systems including
Linux, Microsoft Windows, Mac OS, and Solaris. (A total of 2000 IP
addresses.)  Every room in the building is wired with multiple
Category 5/5e UTP ports, single-mode fiber, multimode fiber, and RG6
coaxial cable. Networking is supported by a high-speed core switch
with an aggregate switching bandwidth of 480 Gb/sec. Typically,
servers are connected via gigabit Ethernet and user PC/workstations
are connected via switched 100 Mb/sec Ethernet. The department has a 1
Gb/sec connection to the Internet.

The department supports remote users via the Internet and ADSL. The
entire building and some outlying areas are covered by the
department's 802.11a/b/g wireless network. The department
infrastructure and users are protected by firewalls, e-mail virus/spam
scanners, and an IDS system. The general purpose computing facilities
include Sun Solaris (Sparc) and Linux (x86) servers as well as a Linux
cluster. The Linux cluster includes 80 processing cores and 160
gigabytes of memory in 20 compute nodes. There are public Sun Ray
terminals and public printers located throughout the building. The
department has approximately 800 users that share 35 terabytes of disk
space on multiple fileservers.

In this talk, I will give an overview of our department's computing
and networking infrastructure.  This will include a discussion of our
operations, current equipment, and some projects we will be rolling
out soon.
