Disk Because the Management Server software requires
only 250 MB, and the JET database has a
maximum size of 1 GB, 9 GB of disk space is
sufficient. Use a 4 GB partition for the operating
system (including the swap file).
All IBM NAS products exceed the minimum hardware requirements for operating an
IBM Director Agent.
Director extensions
A portfolio of advanced management tools for IBM-specific hardware is provided by
IBM Director as a set of optional enhancements. These tools integrate into IBM
Director and provide management capabilities from a single console with a
consistent look and feel. These extensions are provided as part of the preinstalled
IBM Director Agent on the IBM NAS appliances:
v Management Processor
v
Assistant Capacity Manager
v Cluster Systems Management
v
Rack Manager
v Software Rejuvenation
v
Systems Availability
To use these extensions, you must load them on the IBM Director Management
Server during installation.
Naming conventions
All IBM Director Agents have a Director system name that it is known by the
Management Server and Consoles. This Director System Name is defaulted to the
computer name during the NAS appliance preinstallation process
1
. The Director
system name does not have to be the same as the computer name. The Director
system name is displayed on the IBM Director Console to identify the NAS
Appliance under the Group Contents column. You can optionally change the
Director System Name on an agent using the following procedure:
1. Open a command prompt window and enter the following IBM Director Agent
command to open the GUI interface:
twgipccf.exe
2. Type the new Director System Name and click OK .
The change takes place immediately.
Note: You might need to delete the NAS appliance from the Group Contents and
have it rediscover the appliance by its new name.
Web-based access
IBM Director Agent uses an Apache Web Server for Web-based access. All traffic,
even logon, is certificate-based encrypted. The Web server requires two ports. One
port (411) accepts non-SSL HTTP requests and automatically redirects to the
second port (423), which handles SSL requests.
1. Although you can do so, it is recommended that you not change the default computer name to avoid the chance of propagating
misidentification through the system. And, if you are using IBM Director to manage your appliance, and you change the default
name, the default name continues to appear in IBM Director.
