Network Configuration Examples
Example of
Bi-directional
Configuration -
Zoning and
Optional LUN
Mapping Figure 8-3 provides an example of a bi-directional configuration
using FC/SCSI Tape Pipelining with Fibre Channel switch zones. The
zones for this example are defined in Table 8-2. See the “Required
Fibre Channel Switch Zoning” section on page -4 to determine when
zoning is necessary.
The Edge will do automatic host LUN mapping on a first learned
basis, which will fill the host LUN map from the lowest to the highest
order. Static LUN mapping can be used to designate the desired order
of the host LUN map, as in this example. To determine why and
when to do static mapping, see the “Required Static Edge LUN
Mapping” section. Table 8-4 and Table 8-5 (page -7) define the static
Edge LUN mapping for nodes 10 and 20.

Mapping
Required Fibre
Channel Switch
Zoning Fibre Channel switch zoning is required to isolate individual devices
from specific servers. When an UltraNet Edge 3000 is part of a
network configuration, it is automatically mapped to its peer. Devices
that are visible to one node are automatically mapped into the peer
node’s LUN map and vice versa. When a zone is defined, the devices
an Edge node has access to are determined by the members defined
in its zone.
