storage of management information using an SQL database. The Management
Server maintains a database of all Director Agents and their inventory. All alerts
from the agents flow to the management server, which also acts as a central point
of configuration for Event Action Plans and System Tasks.

The

Agent

resides on the NAS Appliances and other systems that IBM Director

manages. IBM Director recognizes two types of managed systems: native agents
(IBM Director Agent installed) and nonnative agents (SNMP agent installed). The
Agent comes preinstalled on all IBM NAS appliances. It runs as a service that is
automatically started at boot time. IBM Director Agent provides valuable information
to IBM Director management server and other supported management applications.
In addition to its native interface with the Director Management Console, it provides
point-to-point remote management of client systems through a Web browser
window.

You perform administrative tasks at the

Console

. It is a Java application that serves

as the user interface to the Director-managed environment. The console provides
comprehensive hardware management using a single click or drag-and-drop
operation. You can install the console on a machine at a remote location from the
server. Consoles are not licensed, so you can distribute them freely among
unlimited number of machines. In addition, there is no limit to the number of IBM
Director Consoles that can connect into the Management Server.

Dependencies

The IBM Director 3.1 Agent (the version included in this release) must be managed
by an IBM Director 3.1 Management Server. If your Management Server is running
an earlier version of IBM Director (V2.2 or earlier), then you must upgrade it to
ensure proper operation. This includes Director Consoles as well. The IBM Director
3.1 Management Server contains an Agent software distribution package that you
can use to upgrade pre-version 3.1 Agents. This allows easy and automated
upgrading of the entire system to version 3.1. You can check the version of IBM
Director Agent running on a NAS appliance by issuing: http://<system_name>:411/
on a local Web browser.

Hardware requirements

It is highly recommended that you install the IBM Director Server on a server
separate from the IBM NAS appliance. The IBM Director Server running on an IBM
NAS appliance will significantly reduce its performance. The server must meet
these minimum requirements:

Hardware vendor

Must be IBM. The management tools of IBM
Director and Director Extensions require IBM
equipment.

CPU

A 733 MHz PIII processor is recommended.
Standard PII processors can be functional, but
these processors might not be sufficient during
heavy usage.

Memory

512 MB RAM is recommended. During idle times,
while using the standard JET database, the
Management Console can consume 300+ MB
RAM. The number of managed agents, active
consoles, and amount of alerts being processed
increases the amount of memory needed.
