About Fibre Channel Storage Systems and Networks (SANs)

Figure 1-4 A Switch Zone

If you do not define a zone in a switch, all adapter ports connected to

the switch can communicate with all SP ports connected to the

switch. However, access to an SP does not necessarily provide access

to the SP’s storage; access to storage is governed by the Storage

Groups you create (defined later).

Fibre Channel switches are available with 16 or 8 ports. They are

compact units that fit in 2 U (3.5 inches) for the 16-port or 1 U (1.75

inches) for the 8-port. They are available to fit into a rackmount

cabinet or as small deskside enclosures.

To illustrate switch zoning, this figure shows just one HBA per server and one

switch or hub. Normally, such installations will include two HBAs per server

and two switches or hubs.
