This chapter provides an overview of the tasks you can perform with SGI InfiniteStorage NAS Manager and an introduction to the interface:

System Management and Monitoring with NAS Manager

NAS Manager is a web-based interface that lets you configure, manage, and monitor an SGI InfiniteStorage NAS Server.

You can use NAS Manager to do the following:

Perform initial system configuration using the Setup Wizard
Configure the system components
Perform general system administration tasks
Monitor current and historical views of a fileserver's state and performance (including disk space, CPU usage, and network throughput)
View connected clients and determine how each of these contribute to the current workload
Detect and investigate problems

Monitor the Data Migration Facility (DMF) and perform certain DMF configuration tasks

Note: DMF is a hierarchical storage management system for SGI environments. DMF version 3.4 and later is supported by NAS Manager. Consult the release notes for the procedure to activate the DMF monitoring screens. DMF support requires an additional license, in addition to those for DMF and the base NAS Manager products themselves.

NAS Manager Interface

To access the NAS Manager features, click on one of the menu options displayed across the top of the NAS Manager screen. As you page through NAS Manager, your location is shown below the menu options. You can also click on an item in this path to directly access that location. For example, Figure 1-1 shows the screen you would see if you selected the CPU Utilization item from the Resources category on the Monitoring menu page. This is menu path is shown in this guide as the following:
