Terapix system is within the IAP network.
All the machines have a 100 megabit ETHERNET card. Some have also a gigabit ETHERNET card. The Terapix machines are in a switched area (using a 10/100 megabit switch), allowing heavy use of network transfert.
Here is a logical drawing of the network for TERAPIX.
fibre channel device could be installed to avoid ethernet bottle neck
Gigabit Ethernet technology : switch giga/100mega
