Introduction Introduction This article highlights the superb performance and high availability demonstrated when you install HP’s new PCI-X multi-function 2 Gbit/s Fibre Channel and Gigabit Ethernet adapters in HP’s award-winning midrange rp8400 servers with Server Expansion Units (SEU). The new A9782A adapter (with fiber-based GigE) and the A9784A adapter (with copper-based GigE) provide the following benefits: A single adapter combining 2 Gbit/s Fibre Channel mass storage connectivity and •... - Page 4 Introduction 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. •...

Page 12: Performance Highlights
Performance Highlights Performance Highlights The A9782A and A9784A adapters when installed in an rp8400 with Server Expansion Unit (SEU) provide exceptional connectivity, reliability, and flexibility for networking and mass storage. When both ports on the adapter are concurrently transferring data, the adapter provides excellent fiber channel performance and good Gigabit Ethernet performance. - Page 13 Suggested Use Figure 8 Two HP Multi-Function Adapters Configured to Provide Both High Availability and Best Performance Primary Alternate Fibre Channel Port GigE Port 1000B-T FIBRE 1000 CHANNEL PCI-X 133 MHz LNK/ACT 1000B-T FIBRE 1000 CHANNEL PCI-X 133 MHz LNK/ACT Primary Alternate Fibre Channel...
- Page 14 Suggested Use Use PCI-X mode as opposed to PCI mode. The primary PCI-X bus running at 133MHz • PCI-X with 64-bit bus width will yield the best results and the performance comparable to that shown in this paper. HP tested the A9782A and A9784A adapters in PCI mode, but because PCI performance is lower than PCI-X performance, HP recommends using these adapters in PCI-X mode rather than PCI.
