1. Overview of HDLM

1.1 What is HDLM?
The widespread use of data warehousing and increasing use of multimedia data have
increased the need for high-speed processing of large volumes of data on networks. To
satisfy this need, networks dedicated to data transfer, such as a SAN, are now being
used to provide access to storage systems.
The HDLM software manages access paths to storage systems. HDLM uses MPIO
functionality supported by AIX 5L V5.2 or later.
HDLM, as an extended module of MPIO, provides functionality for distributing the
load across paths and switching to another path if there is a failure in a path being used,
thus improving system availability and reliability.
Figure 1-1: Connections between hosts and storage systems illustrates the
connections between hosts and storage systems. A server on which HDLM is installed
is called a host.

HDLM supports the following storage systems.
