What is HDLM? With the widespread use of data warehousing and increasing use of multimedia data, the need for high-speed processing of large volumes of data on networks has rapidly grown. To satisfy this need, networks dedicated to the transfer of data, such as SANs, are now being used to provide access to storage systems. HDLM manages the access paths to these storage systems. HDLM provides the ability to distribute loads across multiple paths and switch to another path if there is a failure in the path that is currently being used, thus improving system availability and reliability. Figure 1-1 Connections Between Hosts and Storage systems on page 1-2 illustrates the connections between various hosts and storage systems. An ESXi server that connects to a storage system via a SAN is called a host. A machine that connects to a host via a LAN and uses commands and utilities to control it is called a remote management client.

What is HDLM?
With the widespread use of data warehousing and increasing use of
multimedia data, the need for high-speed processing of large volumes of data
on networks has rapidly grown. To satisfy this need, networks dedicated to
the transfer of data, such as SANs, are now being used to provide access to
storage systems.
HDLM manages the access paths to these storage systems. HDLM provides
the ability to distribute loads across multiple paths and switch to another path
if there is a failure in the path that is currently being used, thus improving
system availability and reliability.

illustrates the connections between various hosts and storage systems.
An ESXi server that connects to a storage system via a SAN is called a host. A
machine that connects to a host via a LAN and uses commands and utilities
to control it is called a remote management client.
