Configuring the Optional
Entry-Level DRM Solutions
This chapter describes the entry-level DRM solutions and explains how to set up and
configure them.
This chapter covers the following topics:
■ Dual-Switch Single-Site Configuration‚ page 150
■ Single-Switch Configuration‚ page 152
■ Single-Fabric Configuration‚ page 154
Note: It is a good idea to keep a copy of this manual at both the initiator and target sites to ensure
a successful and identical setup at both sites. Two copies also eliminate confusion if more than one
person is configuring DRM.
