In a mainframe environment, SSIDs are used for reporting information
from the control unit (CU) image to the mainframe operating system. An
SSID is assigned to each group of 64 or 256 volumes to define one or four
SSIDs per CU image. The user-specified SSIDs are assigned during
storage system installation and must be unique to all connected host
operating environments.
