Environment
You can view the overall environmental status for the attached array by
launching the Command View SDM web interface. This interface opens in
another browser window and gives you more detailed information about the
array. The Command View SDM web interface lets you see more specific
status information. For example, you can view a graphical representation of
the array and its components. By clicking on the components, you can get
further detailed information about the component and its status.
In the Status area on the Command View SDM, you also are able to review
the total capacity of your array, including both allocated and unallocated
storage.
Performance
You can view performance information on the array by launching the
Command View SDM web interface. This interface opens in another browser
window. You can obtain performance on any of 27 different performance
metrics. You are able to select the specific performance parameters that you
are interested in reviewing, add them to a graph, and view the information at
an interval rate you select. Some of the performance parameters that you can
review include:
■ Read or write cache hits
■ Read or write command latency
