2.3.4 Directory Module

In a GS160/320 system, one directory module is required for each QBB

in a system box. In a two-drawer GS80 system, a directory module is

required in each system drawer. No directory module is needed in a

one-drawer system. The directory module functions as a memory

coherency manager.
