Multiswitch Fabric Support A Fibre Channel topology that consists of one or more interconnected switch (or director) elements is called a fabric. The director operational software provides the ability to interconnect directors (through E_Port connections) to form a multiswitch fabric. Fabric elements cooperate to receive data from the N_Port of an attached device, route the data through the proper switch ports (F_Ports), and deliver the data to the N_Port of a destination device. The data transmission path through the fabric is typically determined by the fabric elements and is transparent to the user. Subject to zoning restrictions, devices attached to any of the interconnected switches can communicate with each other through the fabric. A multiswitch fabric is typically complex, and provides the facilities to maintain routing to all device N_Ports attached to the fabric, handle flow control, and satisfy the requirements of the classes of Fibre Channel service that are supported. Figure 19 illustrates a multiswitch fabric supported by three directors. Figure 19 Example Multiswitch Fabric 74 Multiswitch Fabric Support

Multiswitch Fabric Support

A Fibre Channel topology that consists of one or more interconnected switch (or director)

elements is called a fabric. The director operational software provides the ability to

interconnect directors (through E_Port connections) to form a multiswitch fabric. Fabric

elements cooperate to receive data from the N_Port of an attached device, route the data

through the proper switch ports (F_Ports), and deliver the data to the N_Port of a

destination device. The data transmission path through the fabric is typically determined

by the fabric elements and is transparent to the user. Subject to zoning restrictions, devices

attached to any of the interconnected switches can communicate with each other through

the fabric.

A multiswitch fabric is typically complex, and provides the facilities to maintain routing to

all device N_Ports attached to the fabric, handle flow control, and satisfy the requirements

of the classes of Fibre Channel service that are supported. Figure 19 illustrates a

multiswitch fabric supported by three directors.
