Topology

An interconnected set of nodes.

A logical topology, in the context of storage partitioning definitions, is a collection of Default Host Group , Host Group , Host and Host Port nodes in the Topology View.

A physical topology, for storage subsystems with fibre channel host interfaces, is the interconnect method between a storage subsystem controller and a host. The Storage Subsystem >> Profile option displays one of the following values in the Topology field:

Topology

Description

Point-to-Point

The controller port and host port are directly connected as N-ports (non-loop).

Arbitrated Loop - Public

The controller port is connected to a switch port via a fibre channel arbitrated loop. The host port may be on the local loop or connected to the switch.

Devices on the loop and devices attached to the switch can communicate with each other.

Arbitrated Loop - Private

The controller port and host port are connected by a fibre channel arbitrated loop.

Fabric Attach

The controller port is connected as an N-port to the fabric (switch) port. The host port is connected somewhere else in the fabric. The switch facilitates communication between the controller port and the host port.
