2.10 Interconnect types
The interconnect type resource defines the characteristics of a model of interconnect, such as the
following:
• Downlink capabilities and the number of downlink ports
• Uplink port capabilities and the number of uplink ports
• Supported firmware versions
Relationship to other resources
An interconnect type resource is associated with the following resources in the resource summary
diagram (page 32):
• Zero or more interconnects
UI screens and REST API resources
NotesREST API resourceUI screen
The UI does not display or refer to the
interconnect type resource specifically,
but the information is used by the
appliance when you add or manage
an interconnect using the Interconnects
screen.

2.11 Interconnects
An interconnect is a physical resource that enables communication between hardware in the
enclosure and the data center Ethernet LANs and Fibre Channel SANs. The HP Virtual Connect
FlexFabric 10Gb/24-port Module is an example of a supported interconnect. For a list of supported
interconnects, see the HP OneView Support Matrix.
An interconnect has the following types of ports:
DescriptionPort type
Uplinks are physical ports that connect the interconnect to the data center networks. For example,
the X2 port of an HP Virtual Connect FlexFabric 10Gb/24-port Module is an uplink.
Uplinks
Downlinks are physical ports that connect the interconnect to the server hardware through the
enclosure midplane.
Downlinks
Stacking links are internal or external physical ports that join interconnects to provide redundant
paths for Ethernet traffic from servers to the data center networks.
Stacking links
In the resource model:
• Interconnects are an integral part of enclosures and enclosure groups. The interconnects
installed in an enclosure are added automatically when the enclosure is added to the appliance.
To remove an interconnect from the appliance, you must remove the enclosure from the
appliance.
• Interconnects can also be defined by a logical interconnect group, which in turn defines the
logical interconnect configuration to be used for an enclosure. When you associate an enclosure
with an enclosure group during an add operation, the appliance uses the interconnect
configuration defined by the logical interconnect group that is associated with the enclosure
group. The physical interconnect configuration in the enclosure must match the logical
interconnect group configuration before an interconnect can be managed.
