Ultra320 SCSI Storage Enclosures Configuring a Split-bus Enclosure In a split-bus configuration, the Ultra320 Storage Enclosure provides two six-slot single buses. Both buses can be connected to one dualSCSI-channel host, or each SCSI bus can be connected to its own host. You must use high-quality Ultra320 SCSI cables to connect to the hosts. High-quality Ultra320 SCSI cables are available for sale on the Adaptec Web site at www.adaptec.com. To connect a split-bus enclosure to one or two host systems: 1 Shut down your host system. 2 Connect an Ultra320 SCSI cable to a host system. 3 Connect a second Ultra320 SCSI cable to either the same host system or to a second host system. 4 Connect the other ends of the cables to the VHDCI SCSI connectors on the Ultra320 Storage Enclosure. 5 Secure the ends of both cables by tightening the connector thumbscrews. Ultra320 SCSI Joined-bus Configurations A joined-bus configuration has two separate buses joined to make one SCSI bus with up to twelve disk drives. In this configuration, the enclosure has an I/O module in one I/O slot, and an Joiner module in the other. You must use a Joiner module to use the Ultra320 Storage Enclosure in single-bus mode. Joined-bus SCSI IDs The Ultra320 SCSI Storage Enclosure's SCSI IDs are hard set and cannot be changed. In a joined-bus enclosure, the bus has 14 SCSI IDs. SCSI ID 6 and 7 are reserved for the hosts. The I/O module has SCSI ID 15. 7-5

Ultra320 SCSI Storage Enclosures
Configuring a Split-bus Enclosure
In a split-bus configuration, the Ultra320 Storage Enclosure provides
two six-slot single buses. Both buses can be connected to one dual-
SCSI-channel host, or each SCSI bus can be connected to its own host.
You must use high-quality Ultra320 SCSI cables to connect to the
hosts. High-quality Ultra320 SCSI cables are available for sale on
the Adaptec Web site at
www.adaptec.com
.
To connect a split-bus enclosure to one or two host systems:
1
Shut down your host system.
2
Connect an Ultra320 SCSI cable to a host system.
3
Connect a second Ultra320 SCSI cable to either the same host
system or to a second host system.
4
Connect the other ends of the cables to the VHDCI SCSI
connectors on the Ultra320 Storage Enclosure.
5
Secure the ends of both cables by tightening the connector
thumbscrews.
Ultra320 SCSI Joined-bus Configurations
A joined-bus configuration has two separate buses joined to make
one SCSI bus with up to twelve disk drives. In this configuration,
the enclosure has an I/O module in one I/O slot, and an Joiner
module in the other.
You must use a Joiner module to use the Ultra320 Storage
Enclosure in single-bus mode.
Joined-bus SCSI IDs
The Ultra320 SCSI Storage Enclosure’s SCSI IDs are hard set and
cannot be changed.
In a joined-bus enclosure, the bus has 14 SCSI IDs. SCSI ID 6 and 7
are reserved for the hosts. The I/O module has SCSI ID 15.
