Specifications - IBM SAN24B-6 Product Manual

Organizations can easily enable Access Gateway mode via IBM Network Advisor or a
command-line interface (CLI). Access Gateway mode includes these key benefits:
Improved scalability for large or rapidly growing server and virtual server environments
Reduced management of the network edge because Access Gateway does not have a
domain identity and appears transparent to the core fabric
Support for heterogeneous SAN configurations without reduced functionality for server
connectivity
