FC-AL Disk Controller
The FC-AL disk controller ASIC provides an interface between the 64-bit, 66-MHz
PCI bus, the two FC-AL hard drives, and an external FC-AL connector. The FC-AL
controller provides connection to internal and external devices through one channel.
The FC-AL loop supports up to 125 devices. See Section 10.2.14, "FC-AL Subsystem"

Peripherals

The following peripherals are supported by the Netra T4 system:
Section 10.2.8.1, "DVD-ROM and DAT Drives" on page 10-24
Section 10.2.8.2, "Hard Drives" on page 10-24
Section 10.2.8.3, "System Configuration Card Reader" on page 10-25
10.2.8.1 DVD-ROM and DAT Drives
The DVD-ROM, and back-up devices (tape drive) are interfaced through a SCSI
controller. The Netra T4 system uses a SCSI host controller on the PCI bus. This
controller is used only in fast narrow mode.
Note – The DVD-ROM drive is factory set to SCSI target ID 6. Refer to the
installation documentation for the DVD-ROM to change the target ID address.
10.2.8.2 Hard Drives
The system supports two internal hot-swap FC-AL hard drives. Each hard drive has
a single connector configuration. A drive bracket is used to mount the drives. The
following table lists the features of the Netra T4 hard drives.
