McDATA ULTRANETTM EDGE STORAGE ROUTER 3000 Manual Do Utilizador

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. 

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.
