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.
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 32) :
•
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 .
