Single host, one master subsystem, and two slave subsystems
This configuration provides a Differential SCSI solution using one dual-bus
master CR8e subsystem and two single-bus slave CR8e subsystems connected to a
single host computer with a standard Differential SCSI host adapter. From this
configuration an array can be created using up to twenty-four (24) disk drives —
8 drives per drive group.
Verify that the jumper at location JP1 on the S2S Interface card is removed.
