In this configuration, 32 users can simultaneously access 256 attached computers. Here the 16 x 128 matrix in
Section 7.7.1 is effectively doubled, but any user can still freely connect to any computer. (There aren’t enough
dedicated signal paths from any one EXP to any one Hub, or from any one Hub to any one SB, to make this
work. But because each Hub has at least two paths to each EXP and at least two paths to each SB, there is always
at least one available pathway between each user and each computer.)
This configuration uses four Hubs, 32 ServSwitch Multi SB chassis to connect computers to the system, and
eight ServSwitch Multi EXP chassis to connect the users.
