2.2 System Configuration
HDLM is available in two SAN environment types: FC-SAN and IP-SAN. However, a single host
can connect to either the FC-SAN or IP-SAN. Note that the EMC DMX series, EMC CX series,
and HP EVA series is available only in an FC-SAN environment.
2.2.1 System Configuration Using an FC-SAN
In an FC-SAN, fiber cables connect hosts and storage systems. The cable port on the host is a
host bus adapter (HBA). The cable port on the storage system is a port (P) on a channel
adapter (CHA).
A logical unit (LU) contained in a storage system is the target of input to, or output from,
the host. An area in an LU is called a Dev.
A route that connects a host and a Dev in an LU is called a path.
HDLM assigns an ID to the management-target path. This ID is called a path management
PATH_ID. Also, the path might be called a management target.
Figure 2.1 shows the HDLM system configuration using the FC-SAN.
