Performance balancing is the paired arrangement of expansion boards for optimal
performance based on the bus architecture of the expansion slots. Properly balancing the
boards across buses can improve performance. To balance expansion boards, populate slots
across different buses before populating two slots on the same bus. The table below shows
the preferred order of installation.
Slot 1 133 MHz / 64-bit PCI-X Slot 2 133 MHz / 64-bit PCI-X Slot 3 100 MHz / 64-bit PCI-X Slot 4 100 MHz / 64-bit PCI-X Slot 5 100 MHz / 64-bit PCI-X Slot 6 100 MHz / 64-bit PCI-X Slot 7 100 MHz / 64-bit PCI-X
Slot 8 / 100 MHz / 64-bit PCI-X

Networking
The ProLiant DL585 server has an integrated, dual-port NC7782 Gigabit Server Adapter. The
NC7782 is a PCI-X based LOM (LAN on Motherboard) embedded chip that supports
10/100/1000 Mbps Ethernet speeds and a PCI-X 64-bit/100-MHz data path that is
compatible with existing PCI bus architectures. This LOM supports the standard HP network
controller drivers and functionality, including teaming and failover to the other embedded
NIC port or to stand-up PCI-X expansion card-based NICs.
