Relationship to other resources

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

•Zero or more logical interconnects•Zero or more enclosure groups

The uplink sets defined by a logical interconnect group specify the initial configuration of the uplink sets of each logical interconnect in the group.

2.13 Logical interconnects

A logical interconnect is a single entity for multiple physical interconnects

A logical interconnect is a single administrative entity that consists of the configuration of the interconnects in an enclosure. This configuration includes:

•Interconnects, which are required for the enclosure to connect to data center networks.

•Uplink sets, which map data center networks to physical uplink ports. If no uplink sets are defined, the logical interconnect cannot connect to data center networks, and the servers attached to the downlinks of the logical interconnect cannot connect to data center networks.

•Downlink ports, which connect through the enclosure midplane to the servers in the enclosure. A logical interconnect includes all of the physical downlinks of all of the member interconnects. The downlinks connect the interconnects to physical servers. The set of downlinks that share access to a common set of networks are called logical downlinks.

•Stacking links, which join interconnects either through connections inside the enclosure or external cables between the stacking ports of the interconnects.

•The firmware baseline, which specifies the firmware version to be used by all of the member interconnects. The firmware baseline for physical interconnects is managed by the logical interconnect.

The network administrator configures multiple paths from server bays to networks

The network administrator can ensure that every server bay of an enclosure has two independent paths to an Ethernet data center network by creating a logical interconnect for which the following conditions are true:

•The logical interconnect has at least two interconnects that are joined by stacking links.

•The logical interconnect has at least one uplink set that includes uplinks to the network from at least two physical interconnects.

The appliance detects and reports a configuration or state in which there is only one path (no redundant paths) to a network or in which there are no paths to a network.
