Connectivity of multiple devices overview
This chapter describes how to connect multiple devices to a switch in Access Gateway (AG) mode,
and discusses Edge switch compatibility, target aggregation, direct target attachment, port
requirements, NPIV HBA, and interoperability. AG does not support daisy chaining when two AG
devices are connected to each other in a loop configuration. Switches in AG mode can connect to
third-party fabrics with the following firmware versions:
•
M-EOSc v9.6.2 or later and M-EOSn v9.6 or later.
•
Cisco MDS Switches with SAN OS v3.0(1).
•
Loop devices and FICON channels/control unit connectivity are not supported.
•
When a switch is in AG mode, it can be connected to NPIV-enabled HBAs, or F_Ports that are
NPIV-aware. Access Gateway supports NPIV industry standards per FC-LS-2 v1.4.
Direct target attachment
FCP targets can directly connect to an AG module instead of through a fabric connection.
Even though target devices can directly be connected to AG ports we recommend that target
devices be connected to the core Fabric. Follow the
“Considerations”
below when connecting target
devices directly to an AG.
Considerations
•
Direct Target attachment to AG is only supported if the AG module is also connected to a core
fabric.
A switch module running in AG mode does not provide Name Services on its own, and
routing to the target devices will need to be established by the core fabric.
•
Hosts and targets can not be mapped to the same N-port.
