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

v
PCI 4-Channel Ultra3 SCSI RAID Adapter (type 4-X, feature 2498)
Note: Connection can be to an integrated SCSI port instead of to a SCSI connector
on one of the listed SCSI adapters
Attention: This 2104 configuration is supported on the Linux for pSeries operating
system when attached to the host with the PCI Dual-Channel Ultra3 SCSI Adapter
(type 4–Y, feature 6203).
Attention: The SCSI addresses of the adapters that are connected to the 2104
must be different from each other and from the addresses of the installed disk drive
modules.
Note: A similar configuration that has one adapter with two external SCSI
connectors, instead of the two single-connector SCSI adapters, is also a
valid configuration.
