Chapter 1 Before Configuring SN 5428-2 Storage Router Software

Zoning Overview

Once initiator WWPN1 and initiator WWPN2 are configured, the SN 5428-2 will support fabric zoning using the WWPNs of each FC storage device attached, either directly or on a fabric. The IP hosts participate in zoning via the access list. See the “SCSI Routing Mapping and Access Control” section on page 1-6for more information about access lists.

Figure 1-22shows an example network that employs SN 5428-2 FC fabric zoning. In the figure, the SN 5428-2 is connected to IP hosts A and B through the Gigabit Ethernet interface; the SN 5428-2 Fibre Channel interfaces are connected to FC storage and a zoned FC switched fabric. The IP hosts are allowed access to storage devices in both zones (Y and Z) and storage devices attached to the SN 5428-2. Zone Y has access to all the SN 5428-2 storage devices and zone Z has access to one storage device on the SN 5428-2.

Zoning comprises zones, zone sets, aliases, and zone databases.

A zone is a named group of devices that can communicate with each other. Membership in a zone is defined by the device WWPN. Zone members can communicate only with members of the same zone. The SN 5428-2 supports the soft zone type. Soft zones can overlap; that is, a device can be a member of more than one soft zone.

To make it easier to add devices to one or more zones, you can create an alias. An alias is a named set of devices that are grouped together for convenience. You can add an alias to one or more zones. However, you cannot add a zone to an alias, nor can an alias be a member of another alias.

You can also use an alias to name a single device. This allows you to refer to the device by the alias name rather than the WWPN of the device.

A zone set is a named group of zones. A zone can be a member of more than one zone set.
