Introduction
StorNext is data management software that enables customers to
complete projects faster and confidently store more data at a lower
cost. Used in the world's most demanding environments, StorNext is the
standard for high performance shared workflow operations and
multitier archives. StorNext consists of two components: StorNext File
System (SNFS), a high performance data sharing software, and StorNext
Storage Manager (SNSM), the intelligent, policy-based data mover.
About StorNext File System
Quantum StorNext User’s Guide 1
StorNext File System streamlines processes and facilitates faster job
completion by enabling multiple business applications to work from a
single, consolidated data set. Using SNFS, applications running on
different operating systems (Windows, Linux, Solaris, HP-UX, AIX, and
Mac OS X) can simultaneously access and modify files on a common,
high-speed SAN storage pool.
This centralized storage solution eliminates slow LAN-based file
transfers between workstations and dramatically reduces delays caused
by single-server failures. In high availability (HA) configurations, a
redundant server is available to access files and pick up processing
requirements of a failed system, and carry on processing.
Chapter 1: Introduction
About StorNext Storage Manager
About Distributed LAN Clients
StorNext Storage Manager enhances the StorNext solution by
reducing the cost of long term data retention, without sacrificing
accessibility. SNSM sits on top of SNFS and utilizes intelligent data
movers to transparently locate data on multiple tiers of storage. This
enables customers to store more files at a lower cost, without having to
reconfigure applications to retrieve data from disparate locations.
Instead, applications continue to access files normally and SNSM
automatically handles data access – regardless of where the file resides.
As data movement occurs, SNSM also performs a variety of data
protection services to guarantee that data is safeguarded both on site
and off site.
StorNext supports
SAN client, a distributed LAN client does not connect directly to
StorNext via fibre channel or iSCSI, but rather across a LAN through a
gateway system called a
server is itself a directly connected StorNext client, but it processes
requests from distributed LAN clients in addition to running
applications.
Any number of distributed LAN clients can connect to multiple
distributed LAN servers. StorNext File System supports Distributed LAN
client environments in excess of 1000 clients.

Besides the obvious cost-savings benefit of using distributed LAN
clients, there will be performance improvements as well.
Distributed LAN clients must be licensed in the same way as StorNext
SAN clients. When you request your permanent StorNext license, you
will need to specify the number of distributed LAN clients you plan to
use. Naturally, you can always purchase additional distributed LAN client
licenses as your needs expand. For more information about StorNext
licensing, see
StorNext provides distributed LAN client information via the status
monitors on the StorNext home page. More detailed information is
available through the Clients Report and the Distributed LAN Client
Performance Report. For more information about StorNext reports, see
StorNext Reports on page 205.
Before you can fully use distributed LAN clients, you must first configure
a distributed LAN server and distributed LAN clients as described in the
StorNext Installation Guide

Purpose of This Guide
About Licensing Beginning with StorNext 4.0, licensing has changed significantly
compared to previous releases. Multiple licenses are now required for
various StorNext features, as well as to perform an upgrade to a new
release.
If you have not already installed StorNext 4.0 (or upgraded from a
previous release), be sure to read the procedure in the section
Licenses on page 19 before you proceed.
Step 2:
Purpose of This Guide
This guide is intended to assist StorNext users perform day-to-day tasks
with the software. This guide also describes how to generate reports.
Quantum recommends using the graphical user interface to accomplish
tasks, but an appendix provides alternative procedures for users who
wish to perform those tasks via the command line interface.

StorNext GUI Overview
This section describes how to access and navigate through the StorNext
GUI.
This chapter includes the following topics:
• Accessing the StorNext GUI
• The StorNext Home Page
Note: StorNext supports internationalization for the name space of
the file system. This support is fully UTF-8 compliant. It is up to
the individual client to set the proper UTF-8 locale.
Accessing the StorNext GUI
The StorNext GUI is browser-based and can be remotely accessed from
any machine with access to the StorNext server.
Use this procedure to access the StorNext GUI.
1 Open a Web browser.
Quantum StorNext User’s Guide 7
Chapter 2: StorNext GUI Overview
Accessing the StorNext GUI
Note: The following browsers have been tested to work with
StorNext. Browsers not listed may work but are not
recommended.
• Internet Explorer 7.x and 8.x
•FireFox 3.x
To ensure proper browser operation, all monitors must be set to
display at a minimum resolution of 1024 x 768. If you use a
popup blocker, be sure to enable pop-ups in order to ensure
that StorNext displays properly.
2 In the browser’s Address field, type the full address of the machine
and its port number, and then press Enter. For example: http://
<machine name>:<port number>. Use the name of the machine and
port number you copied when you installed the StorNext software.
Note: Typically, the port number is 81. If port 81 is in use, use the next
unused port number. (I.e., 82, 83, etc.)
