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:

Port type	Description
Uplinks	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.
Downlinks	Downlinks are physical ports that connect the interconnect to the server hardware through the
	enclosure midplane.
Stacking links	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.

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.

•An interconnect must be a member of a logical interconnect. For an interconnect to be usable, it must be installed in an enclosure and must be defined as part of a logical interconnect. Each physical interconnect can contribute physical uplink ports to an uplink set.

•Firmware baselines and firmware updates for physical interconnects are managed by the logical interconnect.
