Black Box KV162A 3 a 32 X 256 Matrix, 10. a 32-user, 256-computer Multi system using four Hubs

SERVSWITCH™ MULTI

7.7.3 A 32 X 256 MATRIX

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.

32 SBs, each with at least four Transmit Cards and eight CPU Cards installed, and 256 CPUs

Four Hubs,	512 CAT5
each with	cables
at least	between
4 Receive	Hubs and
Modules	SBs,
and	128 CAT5
2 Transmit	cables
Modules	between

	EXPs

Eight EXPs, each with at least four Receive Cards and four User Cards installed, and 32 user stations
