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.
