2. HDLM Functions
9
2.2 System Configuration
HDLM is available in two SAN environment types: FC-SAN and IP-SAN. Note that
the EMC DMX series, EMC CX series, and HP EVA series can only be used in an
FC-SAN environment.
2.2.1 System Configuration Using an FC-SAN
In an FC-SAN, fiber cables connect hosts to storage systems. The cable port on the
host is called a host bus adapter (HBA). The cable port on the storage system is called
a port (P) on a channel adapter (CHA).
A logical unit (LU), which lies in a storage system, is either an input target or an output
target to or from a host. The areas within an LU are called Devs.
A route that connects a host to a Dev in an LU is called a path.
HDLM assigns a unique ID to each management-target path. This ID is called
AutoPATH_ID. Sometimes, the path is also just simply called a management target.
Figure 2-1: Configuration of an HDLM System When Using an FC-SAN shows the
configuration of an HDLM system using an FC-SAN.
