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.

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.
