5 Bypass Terminology Explanation

5.1 Overview

DURAstream™ Bypass Switches allow you to customize various attributes of the
heartbeat packets that are used to determine appliance health. They are shipped
programmed with recommended settings, but can be changed dynamically. The default
settings are suited for most use cases, but can be easily modified to change the parameters
of how the DURAstream™ interacts with the appliance.

5.2 Heartbeat Frequency

The frequency setting will determine how often heartbeats are sent out to the appliance.
Setting the frequency setting to 100ms will cause the bypass switch to send out a total of
10 heartbeats every second.

As the heartbeat transmission rate is increased, the responsiveness to an appliance failure
can be increased.
