NOTE: If you are setting up automated data store synchronization for the first time, you must
restart the HP EFS WAN Accelerator service on both the master and the backup HP EFS WAN
Accelerators to initialize data store synchronization. For detailed information about restarting
the HP EFS WAN Accelerator service, see the
“Starting and Stopping Services” on page 144 .
NOTE: In an out-of-path configuration, to implement failover support, you must also specify a
fixed target rule that specifies both master and backup target appliances. For detailed
information, see
“Setting In-Path Rules” on page 25 .
Enabling
NetFlow You enable and configure NetFlow support in the Advanced Networking - NetFlow
Export page.
NetFlow enables you to export network statistics that provide information about
network users and applications, peak usage times, and traffic routing. NetFlow records
information for each packet ingressing the specified network interface. This data is
then sent to a NetFlow collector, a software package provided by a third party vendor
or an open source.
IMPORTANT: Enabling NetFlow could adversely impact HP EFS WAN Accelerator
performance and increase bandwidth utilization.
Enabling NetFlow support is optional.
