Preface
This book provides information for configuring an IBM
®
ServeRAID
™
controller,
installing device drivers, and installing and using the ServeRAID utility programs
and the IBM ServeRAID Cluster Solution.
Note: The IBM ServeRAID product can be either a controller on an adapter, such
as the one in this option package, or a controller on the system board of
your server. For consistency in this manual, the ServeRAID product is
referred to as a ServeRAID controller, unless it is specifically noted
otherwise.
To install device drivers and utility programs for an IBM ServeRAID controller
that comes as a standard feature on an IBM server system board, see the
installation instructions and CDs provided with your server for instructions.
