SANtegrity Binding Planning Considerations
Fabric and switch binding enhance data security by controlling and monitoring
director, fabric switch, and device connectivity. The name server zoning feature
also provides data security by partitioning devices into restricted-access zones.
Use of the SANtegrity Binding and zoning features in conjunction with each other
must be carefully planned and coordinated. Refer to “Name Server Zoning” on
page 132 for additional information about zoning.
It is recommended you obtain planning assistance from the HP professional
services organization before implementing the SANtegrity Binding feature with
director or switch zoning, especially for multiple fabrics.
Open Trunking
Open Trunking is a feature that optimizes ISL bandwidth use in a fabric
environment. The feature monitors Fibre Channel data rates through multiple
ISLs, dynamically applies a fibre shortest path first (FSPF) networking algorithm
to calculate the optimum path between fabric elements, and load balances Fibre
Channel traffic (from congested links to uncongested links) accordingly. Open
Trunking is shown in Figure 51.
