Appendix A SANnet II 200 FC, SATA, and SATA SE Array Specifications A-3
The following topics briefly describe specific hardware and firmware features.
A.2.1 Hardware Loop ID
Each device communicating on an arbitrated loop requires an AL_PA, the Arbitrated
Loop Physical Address. The host Fibre Channel supports a single hard loop ID in the
range from 0 to 125. The drive channel allows up to 125 devices to be connected to a
single loop.
The controller supports automatic loop ID assignment on the drive channel. A hard
loop address ID is assigned to the disk drives by setting the radial switch.
A.2.2 Firmware Host-Side Connection Mode
The controller default is Loop Only in Host-side Parameters.
