The School of Computer Science at the University of Windsor, through our team of professional support staff, maintains and supports a number of servers and programming environments to serve the diverse needs of the students, faculty, staff and e-vistors (like you). Due to the dynamic nature of computing technology, and the desire of School members to stay on the leading edge of this technology, we are constantly adding and updating new services, which may not appear in this list. Furthermore, machines in faculty offices and research labs are not listed here. Check out the personal home pages of researchers and research groups for that information.

SERVER ENVIRONMENTS

sol.cs.uwindsor.ca and luna.cs.uwindsor.ca are the primary servers that drive hundreds of desktops throughout the School using the X Windows Protocol. These twin Sun Microsystems V880 systems are equipped with fibre-channel disk arrays in a fault-tolerant manner, Gigabit Ethernet, 8 central processing units (in each server), a high-speed bus and 16 gigabytes of RAM each. They run under the Solaris 9 operating environment with modifications for disk drivers and a customized CPU scheduler for maximum time-sharing effectiveness. All Computer Science students are provided with access to these machines.

goedel.newcs.uwindsor.ca is the primary database server that runs the Oracle 8i database system under the Solaris operating environment. In addition, a robotic tape backup and archive system runs on this server. Computer Science researchers and students are given table space in the database on an as-needed basis. This Sun Microsystems 4500 server also runs multiple processors and a large number of high-speed disks arranged in a mirrored disk array.

The School also runs various Windows 2000 servers and secondary Solaris servers to support special needs of the School such as Web-based courses, custom Web sites, and local area networking support.

NETWORK ENVIRONMENTS

The School has spent almost half a million dollars in the last three years to upgrade our network environments. We have dedicated Gigabit Ethernet networking between all servers and computing labs. All traffic in all offices and labs is exclusively switched using high-speed and reliable Cabletron SSR switch/routers. Extensive networks of fibre-optic cables have been installed to every research lab and every office, in addition to CAT 5e copper wiring. Even remote labs in the Leddy Library West Building are connected via high-speed, dedicated fibre-optics. We are very well poised to deliver data at very high speeds using Gigabit Ethernet and/or ATM protocols. A Xylan ATM switch is available in the department for research applications which connects all the primary Computer Science servers with the research network on campus.

Access to the Internet and the rest of campus is provided using a "Smart Trunk" connection between switches in Computer Science and ITS (Information Technology Services), with a capacity of 2 GB/sec.

We have also deployed a wireless network in the Computer Science areas of Lambton Tower/Erie Hall using 802.11b Wi-Fi technology. Authentication is done through a captive portal server. Simply connect to the network CS-WL-2 and then open a Web browser. You will be prompted for your UWin ID and password. The traffic on this network is not encrypted, so use encrypted protocols, such as ssh or https: (SSL) to send sensitive information.


ACCESS

Access to the servers is done via the close to three hundred thin client terminals in Computer Science labs in Room 3150 Erie Hall, 3119 Erie Hall, and 315 West Leddy Library Building. The thin client terminals provide a high-resolution graphics desktop to the servers, and the new SunRay terminals also allow for audio support. The effective use of switched networking, multiple network interfaces, and customized per-user scheduler (instead of the standard per-process scheduler) on the primary servers provides high speed access with little latency time, even when the servers are under heavy load.

A lab of 26 Personal Computers (HP 720n) for multimedia projects is available in Room 3109 Lambton Tower and is connected via high-speed networking to the servers. PC's, Mac's and X terminals in faculty offices and research networks further add to the number of high-speed desktop access points.

Off-campus access is available via the ssh (Secure shell) system. The ssh allows for remote desktops via the X Windows Protocol, but this is not strongly advised due to the lack of consistent high-speed when using external networks.
