Indexed Addressing

Understanding the PSFR-CP41 Configuration

Indexed Addressing table

The Indexed Addressing table has the structure shown in Table. The PSFR-
CP41 will allow up to 80 device entries to be mapped. The index table can be
manually edited, and is then saved to FLASH memory. Configuration assists
allow for the table to be filled in order of increasing target, or LUN, as may be
desired for the specific requirements needed. An assist is also provided to
perform device discovery, and fill the table in the order that devices are
discovered on the SCSI bus.

Indexed Addressing mode is recommended for environments where device
configuration may change, and a fixed mapping from the application to the
target devices is required. An example of such an environment is where hot plug
devices may be used, thereby changing the order of devices on the SCSI bus.
