HP rp8400 servers with Server Expansion Units (SEU) like the one used in this demonstration are highly dependable, adaptable, and efficient midrange servers for the data center.

and High Availability To get the best performance as well as high availability using the A9782A/A9784A, HP recommends the following: • As shown in Figure 8, you can use two multi-function adapters together to achieve both the best performance and high availability. In the event of a system slot - HP 2G | PCI-X 2 Gigabit Fibre Channel and Gigabit EthernetPerformanceUsing the H - Page 13
that your systems are also configured with failover software such as HP Serviceguard and Logical Volume Manager.

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 of 8 equal capacity dual inline memory modules (DIMMs) to take advantage of memory interleaving.
