DRAFT - Overview of IT Infrastructures and Services
I. Cost Estimate Assumptions
The document uses the following replacement cycles: 3 years for software, 5 years
for networking equipment, 10 years for wiring connectors, and 10 years for intra-
building wiring. Staffing costs are calculated using the salary midpoint of the
range plus benefits at 24.96% of salary.
II. Infrastructure & Connectivity
A. Campus Data Backbones
1. Next Generation Backbone :
Switched Gigabit Ethernet (1000 Mb/s) between buildings and switched Fast
Ethernet (100 Mb/s) connections to individual departments. The current
estimate for one-time expense is $1.4M. The current estimate for annual
hardware and software maintenance is $100K. An estimate for running
single-mode fiber to all buildings is $300K (based on a '94 estimate). The
estimate for staffing to support this backbone is adding 2 CNT III FTE to
the existing NOC at $158K. Assuming a 5-year replacement cycle for the
backbone networking equipment, the campus needs to save or defer
$280K/year. There are no estimates yet for the cost of connecting
departments, or backbone operations.
