AD300A PCI-e Dual Port 4 Gb Fibre Channel Adapter
The AD300A is a dual port 4 Gb-capable adapter that operates in PCI 66 MHz and PCI-e 66 MHz/133
MHz/266 MHz bus speeds with a 64-bit bus width. Both ports support Auto-Speed Negotiation, and are
independently capable of 1 Gb, 2 Gb, or 4 Gb data transfer rates. Auto-Speed Negotiation enables each port to
automatically negotiate the highest speed common to the port and the infrastructure connecting the port.
Use the fcmsutil diagnostic tool to display link speed and other Vital Product Data (VPD) information.
The AD300A dual port adapter supports Online Addition and Replacement (OLAR) on OLAR-capable
systems running HP-UX 11i v2. OLAR refers to the ability of a PCI card to be replaced (removed or added)
without shutting down and rebooting the system.
The AD300A dual port adapter supports fabric topologies. The direct attach topology is supported using
arbitrated loop topology.
