The server administrator is not required to know the details about interconnect configurations

Because a logical interconnect is managed as a single entity, the server administrator is isolated from the details of interconnect configurations. For example, if the network administrator configures the logical interconnect to ensure redundant access from each server bay in the enclosure to each Ethernet data center network, the server administrator must only ensure that a server profile includes two connections to a network or to a network set that includes that network.

Relationship to other resources

A logical interconnect resource is associated with the following resources in the resource summary diagram (page 29):

•Zero or more interconnects. For a logical interconnect to be usable, it must include at least one interconnect. If there are zero interconnects, the enclosure and its contents do not have any uplinks to the data center networks.

•Exactly one logical interconnect group, which defines the initial configuration of the logical interconnect, including its uplink sets. Using logical interconnect groups, you can easily and quickly replicate the same logical interconnect configuration across multiple enclosures. After a logical interconnect is created and associated with a logical interconnect group, it continues to be associated with that group and reports if its configuration differs from the configuration of the group. This feature enables you to manage any number of logical interconnects as though they were one by making all the configuration changes to the logical interconnect group, and then, for each logical interconnect, using a single action to update the configuration from the group.

•Zero or more uplink sets, which associate zero or more uplink ports and zero or more networks.

2.14 Uplink sets

An uplink set assigns data center networks to uplink ports of interconnects. The uplinks must be from physical interconnects that are members of the logical interconnect to which the uplink set belongs. An uplink set is part of a logical interconnect. For each logical interconnect:

•An uplink set cannot include a network set.•A network can be a member of one uplink set only.•An uplink set can contain only one Fibre Channel network.•An uplink set can contain multiple Ethernet networks.•You cannot assign two instances of the same network to the same physical port.

Relationship to other resources

An uplink set is part of a logical interconnect or a logical interconnect group.
