Redundant Physical Connection for Virtual Servers (Erl, Naserpour)

How can a virtual server be kept connected when its physical connection fails?

Redundant Physical Connection for Virtual Servers

Problem

If the virtual switch uplink port used by a virtual server fails, the virtual server becomes isolated and unable to connect to the network or any of its hosted IT resources.

Solution

A redundant, physical backup network connection is established for virtual servers

Application

A second physical network card is added to the physical host and is configured as a hot standby uplink port for the virtual switch.
Redundant Physical Connection for Virtual Servers: Redundant uplinks are installed on a physical server hosting several virtual servers. When one fails, another takes over to maintain the virtual servers’ active network connections.
