Introduction This article highlights the excellent performance of HP’s PCI-X 133MHz10 Gigabit Ethernet SR Adapter, AB287A (Figure 1). The performance measurements were done on an HP Integrity rx7640 server. This article also provides suggestions based on the performance and technology that will help you to best meet your business needs.

133MHz bus for different types of traffic combinations (Ethernet transmit, Ethernet receive, Ethernet bi-directional) when the recommended models are used. The AB287A has excellent sustained performance at both 9000bytes MTU and 1500bytes MTU. Figure 2 Performance Summary 10 Gigabit 9000MTU Performance Following are the highlights of the excellent performance achieved when operating at 9000MTU: • • • Receive traffic achieved a sustained throughput of 7.90 gigabits per second, amounting to about 92.

demand was 1.3µs/KByte. Figure 3 shows the throughput achieved by the 10Gigabit adapter operating at 9000MTU. Figure 3:10GigE throughput at 9000MTU 10 Gigabit 1500MTU Performance Following are highlights of the impressive performance achieved during traffic testing at 1500MTU: • Receive traffic achieved 7.05 gigabits per second throughput with a service demand of 4.3µs/KByte. • A throughput of 6.9 gigabits per second was achieved with Transmit traffic; the service demand was 2.7µs/KByte.

Figure 4:10GigE throughput at 1500MTU Recommended Use Based on Performance and Design HP recommends the following usage model to achieve the best performance: • Run the AB287A cards in the highest performing PCI-X slots. Slots 3, 4, 5 and 6 on each of the I/O partitions are the recommended high performance PCI-X slots in the HP Integrity rx7640 used in our performance testing. Please refer to the appropriate Server Installation Guide for information on how to identify high performance slots.

The recommendations mentioned here were followed to achieve the results shown in this article. Card throughput will be affected with non-recommended configurations. Please contact an HP representative for additional help in understanding how to best deploy the AB287. How We Measured 10 Gigabit Ethernet Efficiency This article highlights the AB287A throughput. Throughput is the data transfer rate, or data rate--the amount of time it takes data to move from one place to another.

§ The observed performance results are consistent across all of the same type of I/O slots of the system; On HP Integrity rx7640, the high performance slots are slots 3, 4, 5 and 6 on each of the I/O Partitions. Performance on other slots will be lower. § The core I/O cards in the rx7640 handled minimal site LAN traffic during performance tests. § Processor affinity was used to assign netperf processes to specific CPUs. Table 1 summarizes the products used to measure the performance.
