Valid 2104 Model DU3 Configurations

Only point-to-point connections are allowed between the SCSI interface cards in a 2104 and the SCSI adapter or integrated SCSI port in a using system.

A 2104 Model DU3 that has only one SCSI interface card can be attached to only one SCSI adapter or integrated SCSI port. A 2104 Model DU3 that has two SCSI interface cards can be attached to two SCSI adapters or integrated SCSI ports.

When an internal connector on the adapter is used, the corresponding external connector must not be used to connect to a 2104 Model DU3.

A 2104 Model DU3 can be configured to support either a single SCSI bus or a dual SCSI bus. The setting of the SCSI Bus Split switch on the switch card in the 2104 Model DU3 defines which configuration is to be used.

 

An RS/6000 or IBM Eserver pSeries computer uses one of the following SCSI

 

adapters to connect to the 2104:

 

v PCI SCSI-2 Single-Ended Fast/Wide Adapter (type 4-A, feature 6208)

 

– This adapter has one external SCSI connector and one internal SCSI

 

connector. Both connectors are connected to the same shared SCSI channel.

 

v PCI Single-Ended Ultra SCSI Adapter (type 4-K, feature 6206)

 

– This adapter has one external SCSI connector and one internal SCSI

 

connector. The two connectors are connected to the same shared SCSI

 

channel.

 

v PCI Dual-Channel Ultra2 SCSI Adapter (type 4-R, feature 6205)

 

– This dual-channel adapter has two external SCSI connectors and two internal

 

SCSI connectors. Each pair, consisting of one external and one internal

 

connector, is connected to a separate SCSI channel.

v PCI Dual-Channel Ultra3 SCSI Adapter (type 4-Y, feature 6203)

Note: Feature code 6203 is the only adapter that supports the attachment of the

2104 to a Linux for pSeries operating system.

– This dual-channel adapter has two external SCSI connectors and two internal

SCSI connectors. Each pair, consisting of one external and one internal

connector, is connected to a separate SCSI channel.

 

v PCI 3-Channel Ultra2 SCSI RAID Adapter (type 4-T feature 2494)

 

– This 3-Channel adapter has two external SCSI connectors and one internal

 

SCSI connector. Each connector is connected to a separate SCSI channel.

 

v PCI 4-Channel Ultra3 SCSI RAID Adapter (type 4-X, feature 2498)

 

– This 4-Channel adapter has four external SCSI connectors and two internal

 

SCSI connectors. The Channel 1 and Channel 2 external connectors share

 

the same SCSI bus as the corresponding Channel 1 and Channel 2 internal

 

connectors. The Channel 3 and Channel 4 external connectors have their own

 

non-shared SCSI bus.

An RS6000 or IBM Eserver pSeries computer running Linux for pSeries uses the

PCI Dual-Channel Ultra3 SCSI Adapter (Feature Code 6203, type 4–Y) to connect

to the 2104 Model DU3 or 2104 Model TU3.
