Logical interconnects resource associations
A logical interconnect is a single entity for multiple physical interconnects
A logical interconnect is a single administrative entity that consists of the configuration for a set of 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 is called logical downlinks.
Internal networks, which are used for server-to-server communications without traffic egressing any uplinks.
Stacking links, if used, join interconnects either through connections inside the enclosure or external cables between the face plate 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, or two interconnects are defined in separate logical interconnect groups.
The logical interconnect has at least one uplink set that includes uplinks to the network from at least two physical interconnects.
HPE OneView 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.
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 model summary diagram:
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.
One or more Logical Interconnect Groups associated with an enclosure group, which define the initial configuration of the logical interconnects.
Zero or more Uplink sets, which associate zero or more uplink ports and zero or more networks.
Zero or one Logical Enclosures.
