Zoning

Figure 5-7
Directors and fabric switches support a user configuration that
partitions attached devices into restricted-access groups called zones.
Devices in the same zone can recognize and communicate with each
other through switched port-to-port connections. Devices in separate
zones cannot recognize name server or route table information and
therefore cannot communicate with each other.

Director Zoning

Zoning is enabled and enforced by one of the following processes:
• Software-enforced zoning - For earlier versions of director or
fabric switch firmware (prior to E/OSc Version 6.0), device
configuration at a fabric element enforces zoning by limiting
access to name server information in response to a device query.
Only devices in the same zone as the requesting device are
returned in the query response. This type of zoning is also called
name server zoning or soft zoning.
• Hardware-enforced zoning - For later versions of director or
fabric switch firmware (E/OSc Version 6.0 and later), device
configuration at a fabric element enforces zoning by
programming route tables that strictly prevent Fibre Channel
traffic between devices that are not in the same zone. This type of
zoning is also called hard zoning.
