Both the A9782A and A9784A adapters offer the same level of performance and are
designed with the following advanced features.
The Fibre Channel port in each adapter:
• runs at either 200 MB/s half-duplex or 400 MB/s full duplex data rates.
• provides boot / dump support and auto speed sensing.
• supports 2 to 200 meter LC-to-LC duplex multimode fibre-optic cable and of course
LC-to-SC conversion cables.
• scales up to 16 million SAN nodes.
• operates in full switched fabric Fibre Channel (FC-SW) or FC-AL-2, FC-FLA, FC-PLDA,
and FC-PI architectures.
The Gigabit Ethernet port in each adapter:
• maximizes server CPU efficiency and increases performance through TCP, UDP, and IP
checksum protocol off loading.
• increases network flexibility through support for virtual LANs (VLANs).
• increases throughput through use of HP auto port aggregation (APA) or
• improves reliability and failover through the LAN Monitor capability of HP APA.
• is available in a choice of either a 1000 Base-SX version using multi-mode fiber
supporting distances of up to 550m or a 1000Base-T version using CAT5 or better UTP
cable supporting distances of up to 100m.
HP rp8400 servers with Server Expansion Units (SEU) like the one used in this
demonstration are highly dependable, adaptable, and efficient midrange servers for the
data center. The results in this paper show that the A9782A and A9784A adapters installed
in a server expansion unit like the one on the rp8400 increase your server and data
network efficiency while lowering your total cost of ownership.
