PCI-X 2 Gigabit Fibre Channel and Gigabit Ethernet
Performance Test Results
The Gigabit Ethernet port performance on the A9782A and A9784A was measured with
the following traffic types:
•Transmit (Tx) using netperf with socket size of 128K bytes and message size of 32K
bytes
•Receive (Rx) using netperf with socket size of 128K bytes and message size of 32K bytes
•Bidirectional (BD) running the Tx and Rx tests concurrently
The Fibre Channel port performance on the A9782A and A9784A was measured with the
following traffic types:
•Read (Rd) using diskbench with block size of 128K bytes
•Write (Wr) using diskbench with block size of 128K bytes
•Bidirectional (BD) running the Rd and Wr tests concurrently
The following charts show the overall performance of one PCI-X multi-function 2 Gigabit
Fibre Channel and Gigabit Ethernet adapter in each 1, 2, or 4-cell, 16-way rp8400 with
Server Expansion Unit (SEU). In the enclosed charts:
•the Gigabit Ethernet throughput numbers are shown in Megabits per second, and
•the Fibre Channel throughput numbers are shown in Megabytes per second.
For each measured traffic type (for example, GigE Tx), the results for that traffic type are
shown alongside a comparison of that traffic type when running in conjunction with the
adjacent port running in bidirectional mode (for example, GigE Tx plus Fibre Channel
bidirectional). These comparisons basically show a single port compared to both ports
operating at the same time. The results of PCI-66 testing are also described though not
shown in graphs.
The following charts can be used to compare performance when 1, 2, and 4 cells are
configured per partition.
