Information Technology Infrastructure
Network Operations Center
The Network Operations Center (NOC), in the basement of Library South, is extremely crowded with more than five-hundred servers. No new equipment can be added to the existing space due to utility infrastructure constraints. The installation of any infrastructure related conduits is not possible due to space constraints. The addition of new equipment over the past few years has curtailed the ability of the cooling system to remove heat generated within the space. The electrical load in the room has reached the limit of the backup power supply. A new 12,000 to 15,000 square-foot NOC facility should be located near the campus for reasons of operational procedure and staff access.
Campus Distribution System
A fiber-ring distribution system is routed through abandoned underground Georgia Power Company steam lines. The university leases the pipes for routing cables to all buildings on campus. The ring consists of 432 strands of single-mode fiber optic cable configured with 12 strands of single-strand fiber entering each building and 12 strands exiting the building for communications with the NOC from either direction along the route. Present one-gigabit operation restricts service to one direction. The ring is sufficient for projected new research facilities and other campus expansion.
Georgia State communicates electronically with Georgia Tech and Emory university through shared and leased lines, and with the Village through leased lines. Alpharetta and Brookhaven Centers use lines leased from BellSouth. Fiber optic connection with Alpharetta Center is desirable as envisioned when that technology becomes available locally.
Georgia State IS&T should have an off-site data storage facility. Alpharetta would be an ideal site if fiber connectivity were available. Piedmont Ellis will be connected to the campus network through lines most likely leased from Atlanta Gas Light or Georgia Power.
Typically, signal termination and servers are located on the lowest floor of a building. Vertical distribution within the building is through a pair of multimode fiber strands (one pair per floor from the switch). Horizontal distribution from floor to station outlets and wireless stations is by way of Cat 5e copper cable. Distribution is being upgraded to 100 megabit operation.
Wireless communication covers most campus common areas and extends into classrooms. Approximately 200 wireless networks are live on campus. The Alpharetta campus, as well as residence halls, are also wireless equipped.
Uses of the Distribution System
The Georgia State Network, Voice over IP communications, Campus Environmental Control (EMS), and the Research Network are presently operating over the distribution system. The Student ID and debit card system and the campus security system are scheduled for installations.
