Alarms in Linux Media Servers
Issue 1 June 2005 37
ARB (Arbiter)
S8700 | 8710 only
The Arbiter process runs on S8700 Media Servers to:
● Decide which server is healthier and more able to be active
● Coordinate data shadowing between servers, under the Duplication Manager’s control
At the physical and data-link layers, an Ethernet-based duplication link provides an inter-arbiter
UDP communication path to:
● Enable this arbitration between the active and standby servers
● Provide the necessary status signaling for memory refreshes
