You might also look into a switching hub like Allied Telesyn's 24 port
ethernet switch. There are cabling issues with 100b whatever and if
you do not have 4 pairs to use, or if you are not running PCI bus
hosts, 100 base anything is not likely a good solution. Cisco makes a
ethernet switch that got rave reviews in Data Communications magazine
also. We currently use the Catalyst 1200 series to segment buildings,
connect X-term labs , provide excellent throughput for Novell
servers, and provide layer 3 segmentation and filtering capabilities.
Speaking with several reps from Cisco, 3Com, Allied Telesyn, Bay,
Cabletron.... all seem to agree that you will get better performance
from a properly configured switched 10 MB ethernet environment than
you would from a shared 100 MB environment.
Just my 2 cents.
