About redundancy modes

Redundancy is used to prevent loss of connectivity in the event of a failure. An interconnect is duplicated so if it fails, a backup interconnect is available. HPE OneView uses the following modes of redundancy.

High Availability

Two interconnects on opposite sides of two enclosures that are both available to all enclosures connected with interconnect link modules. This configuration allows for the loss of any single interconnect or enclosure without affecting connectivity of the remaining enclosures.

Redundant

The same interconnect type on both sides of a single enclosure. This configuration allows for the loss of the interconnect on one side without affecting connectivity of the enclosure. The loss of the interconnects on both sides causes the enclosure to lose connectivity.

Non redundant side A

One interconnect in a single side A bay (1, 2, or 3) in an enclosure that can be connected to other enclosures that have an interconnect link module in the same bay. Loss of any interconnect results in loss of connectivity.

Non redundant side B

One interconnect in a single side B bay (4, 5, or 6) in an enclosure that can be connected to other enclosures that have an interconnect link module in the same bay. Loss of any interconnect results in loss of connectivity.
