A6826A - PCI-X Dual port 2Gb/s Fibre Channel Adapter Performance Paper for PCI Platforms

System configuration guidelines
Superdome
To get the throughput and scalability with multiple cards on a Superdome, HP recommends the following:
The cells should be configured with a multiple of 8 equal capacity DIMMs to take advantage of memory
interleaving. The 8 DIMMs should be evenly distributed across the two busses.
Each IO cage of Superdome offers twelve PCI slots, eight 2X and four 4X PCI slots. The 2X slots have 265MB/s
bandwidth and 4X PCI slots have 530 MB/s bandwidth. HP recommends A6826A to be installed in a 4X PCI slot
(Physical slot number 4, 5, 6 or 7) in order to achieve performance shown in this paper. To get a linear scalability
HP recommends up to a maximum of two A6826As per IO cage.
rp8400
To get the throughput and scalability with multiple cards on an rp8400, HP recommends the following:
The cells should be configured with a multiple of 8 equal capacity DIMMs to take advantage of memory
interleaving. The 8 DIMMs should be evenly distributed across the two busses.
rp8400’s IO subsystem offers sixteen PCI slots, two 2X PCI and fourteen 4X PCI slots. The 2X slots have 265MB/s
bandwidth and 4X PCI slots have 530 MB/s bandwidth. HP recommends A6826A to be installed in a 4X PCI slot
(Physical slot numbers 1, 2, 3, 4, 5, 6) to achieve performance shown in this paper. To get a linear scalability HP
recommends a rp8400 should have at least 2 cell partition and with two A6826As installed in any of 1 to 8 4X
PCI slots and a maximum of two A6826As in any of the 9 to 16 4X PCI slots.
rp7400
To get the throughput and scalability with multiple cards on an rp7400, HP recommends the following:
The rp7400 supports up to 4 memory carriers each providing 8 memory slots. All the carriers should be
populated with equal size DIMMs to maximize the memory bandwidth.
rp7400 offers twelve PCI slots, two 2X (a.k.a. Turbo) and ten 4X (a.k.a. Twin Turbo) PCI slots. HP recommends
A6826A to be installed in a 4X slot (Physical slot numbers 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) to achieve
performance shown in this paper. To achieve a linear scalability HP recommends up to a maximum of two
A6826As to be installed in the right IO backplane (Physical slots 7 to 12) and up to a maximum of two A6826As
to be installed in the left IO backplane (Physical slots 1 to 6).
rp5450
rp5450 is designed to be low end mid range system with limited IO capabilities. HP recommends A6826A on
rp5450 to be used as a connectivity solution.
