Hardware Requirements Of Ethernet Pci Adapters; Table 2-7. U575 Pci Adapter Slot Locations; Table 2-8. Maximum Number Of Ethernet Pci Adapters - NEC Express5800/320Ma Manual

Requirements and configuration procedures for the embedded Ethernet PCI adapters
are similar to the procedures for the other Ethernet PCI adapters.

Hardware Requirements of Ethernet PCI Adapters

For fault tolerance, install Ethernet PCI adapters that are in the same team in different
I/O elements. Although teamed Ethernet PCI adapters in the same I/O element are
marked as duplexed in ftSMC, they are not fault tolerant. If the I/O element fails, or if
you remove the physical enclosure that contains the adapters (in a system with more
than one enclosure), network connectivity is lost.
Table 2-7 describes the slot-location requirements and recommendations for the
U574 PCI adapter and the U575 PCI adapter. If you plan to configure Ethernet PCI
adapters into teams, also consider the configuration requirements described in
"Configuring Ethernet Teams" on page

Slot-Location Requirements and Recommendations
For maximum throughput, install U574 PCI adapters and U575 PCI
, adapters in a two-way symmetric multiprocessing (SMP) system. The
data load between teamed gigabit Ethernet PCI adapters is balanced
only in systems with two CPUs in each CPU enclosure.
For best performance, install multi-port Ethernet PCI adapters in slot 2 or
slot 3. (To add slots 2 and 3 in an Express5800/320Ma
install the AK533 attachment kit. See the Express5800/320Ma:
Operation and Maintenance Guide for more information.)
