Hardware Requirements of Ethernet PCI Adapters

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 2-7describes 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 2-14.

Table 2-7. U575 PCI Adapter Slot Locations

System	Slot-Location Requirements and Recommendations
Express5800/32	For maximum throughput, install U574 PCI adapters and U575 PCI
0Ma 3.2 GHz,	adapters in a two-way symmetric multiprocessing (SMP) system. The
3.6 GHz, and	data load between teamed gigabit Ethernet PCI adapters is balanced
Dual-Core	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 3.2 GHz system,
	install the AK533 attachment kit. See the Express5800/320Ma:
	Operation and Maintenance Guide for more information.)

Table 2-8lists the maximum number of Ethernet PCI ports that Express5800/320Ma systems support.
