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.

. The distributed LAN
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 Distributed LAN Client Performance Report. For more information about StorNext reports, see
Chapter 10, StorNext Reports.
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 21 before you proceed.

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.)
