SCSI or SCSI RAID adapter of one of these types:
v PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203)
v PCI 4-Channel Ultra3 SCSI RAID Adapter (type number 4-X, feature code 2498)
v PCI-X Dual Channel Ultra320 SCSI adapter (type number 5702, feature code
5712)
v PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature
code 5703)
Note: The connection can be to an integrated SCSI port instead of to a SCSI
connector on one of the listed SCSI adapters.
Important: An RS/6000 or IBM Eserver pSeries computer running Linux for
pSeries uses the following to connect to the 2104 Model DS4:
v PCI 4-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203)
v PCI-X Dual Channel Ultra320 SCSI Adapter (type number 5702, feature code
5712)
v PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature
code 5703)
Notes:
1. The SCSI address of the adapter that is connected to the 2104 Model DS4
must be different from the addresses of the installed disk drive modules. The
SCSI address of a second adapter, which is connected to a 2104 Model DS4,
can be the same address of the first adapter but must be different from the
addresses of the installed disk drive modules on the same SCSI bus.
