CHAPTER 7: The ServSwitch Multi Hub
7.7.2 A 16 X 384 MATRIX
In this configuration, 16 users can simultaneously access 384 attached computers. Here 256 computers have been added to the 16 x 128 matrix in Section 7.7.1, but any user can still freely connect to any computer.
This configuration uses three Hubs, 48 ServSwitch Multi SB chassis to connect computers to the system, and four ServSwitch Multi EXP chassis to connect the users. With careful cabling, you could interconnect a 16 x 384 matrix using only two Hubs (each with six Receive Modules and two Transmit Modules installed), but this would not leave much room for future growth.
48 SBs, each with at least four Transmit Cards and eight CPU Cards installed, and 384 CPUs
768 CAT5 cables
between Hubs and SBs
Three Hubs, each with at least 4 Receive Modules and 1 Transmit Module installed
96 CAT5 cables between
Hubs and EXPs
Four EXPs, each with at least six Receive Cards and four User Cards installed, and sixteen user stations
