Overview of Storage Navigator
The Hitachi Universal Storage Platform V and Hitachi Universal Storage
Platform VM (herein after referred to as USP V/VM) Storage Navigator enables
users to remotely manage the storage system. This section describes how the
Storage Navigator accesses the storage system.
The storage system has a computer called a service processor (SVP) that is
used for maintenance. The Storage Navigator accesses the SVP to obtain
storage system configuration and status information, and send user-requested
commands to the storage system. The Storage Navigator consists of a group
of Java™ application programs that run on the Java Virtual Machine™ (JVM™).
The SVP functions as a Web server on the JVM, while the Storage Navigator
functions as a Java client. The Java client that runs the Storage Navigator is
called a Storage Navigator computer.
The Storage Navigator communicates with SVPs on the storage systems via a
local-area network (LAN). The supported interfaces between the Storage
Navigator and the SVP are graphical user interface (GUI) and command line
interface (CLI).
Storage Navigator GUI
The Storage Navigator GUI allows users to perform operations on the storage
system using the Storage Navigator windows displayed on a Web browser.
The SVP contains Java applications that function as the Storage Navigator on
Java clients. Each time you log into the Storage Navigator and connect to the
SVP, a Java application is downloaded from the SVP to the Storage Navigator
computer.
The USP V/VM can be connected to two LANs. The USP V/VM-internal LAN is a
private LAN that is used to connect the SVPs of multiple storage systems. Your
intranet is a public LAN that allows you to access one or more SVPs from
individual Storage Navigator computers. This configuration allows you to easily
access and control the registered storage system. In a SAN environment,
where several storage systems may be connected together, you must
designate a primary SVP, which can be either an SVP connected to a storage
system, or a Web server with the exact same configuration as an SVP (see
Starting Up and Logging Into Storage Navigator).
The following figure shows an example of Storage Navigator computer and
SVP configuration.
