About redundant connectivity with MPIO
The MPIO feature enables you to configure multiple physical I/O paths (interfaces) for redundant connectivity with the local network, storage system, and iSCSI initiator. Both Core and Edge offer MPIO functionality. However, these features are independent of each other and do not affect each other.
MPIO in Core
The MPIO feature enables you to connect Core to the network and to the storage system through multiple physical I/O paths. Redundant connections help prevent loss of connectivity in the event of an interface, switch, cable, or other physical failure.
You can configure MPIO at the following separate and independent points:
• iSCSI initiator—This configuration allows you to enable and configure multiple I/O paths between the Core and the storage system. Optionally, you can enable standard routing if the iSCSI portal is not in the same subnet as the MPIO interfaces.
• iSCSI target—This configuration allows you to configure multiple portals on the Edge. Using these portals, an initiator can establish multiple I/O paths to the Edge.
