• Automatic Replication Trigger - In the Directory/File Based
Replication, a file is automatically replicated after it is closed (CIFS
shares) or after several minutes of inactivity (NFS shares) (see
Directory/File or Cartridge Based Replication on page 115). There is
no need for scripting to execute this function. This action makes
files at the target available for access without a local recovery
operation.
• Enhanced Usability - The user interface of the remote management
console has been updated and improved to make it easier to see
important information at a glance and perform the most common
tasks (see DXi4701 Remote Management on page 45).
Note: For a list of all menus and pages in the remote
management console, see DXi4701 Management Pages on
page 55. Use this list to help find the new location of
features in the remote manage console.
• Custom Network Configuration - You can now create a custom
network configuration using the remote management console as
well as through the CLI (command line interface). The custom
network option allows you to configure the DXi4701 with individual
IP subnet information for each physical interface (see Network on
page 303).
• Configuration Wizards - New wizards provide guided assistance to
help users configure key features of the DXi4701, such as storage
presentation and data replication. Each wizard leads you step-by-
step through the configuration process (see DXi4701 Configuration
Wizards on page 57).
