About High Availability
High Availability (HA) ensures that a vShield Edge appliance is always available on your virtualized network.
You can enable HA either when installing vShield Edge or on an installed vShield Edge instance.
Stateful High Availability
The primary vShield Edge appliance is in the active state and the secondary appliance is in the standby state.
All vShield Edge services run on the active appliance. The primary appliance maintains a heartbeat with the
standby appliance and sends service updates through an internal interface.
If a heartbeat is not received from the primary appliance within the specified time (default value is 6 seconds),
the primary appliance is declared dead. The standby appliance moves to the active state, takes over the interface
configuration of the primary appliance, and starts the vShield Edge services that were running on the primary
appliance. When the switch over takes place, a system event is displayed in the System Events tab of Settings
& Reports. Load Balancer and VPN services need to re-establish TCP connection with vShield Edge, so service
is disrupted for a short while. Virtual wire connections and firewall sessions are synched between the primary
and standby appliances, so there is no service disruption during switch over.
If the vShield Edge appliance fails and a bad state is reported, HA force syncs the failed appliance in order to
revive it. When revived, it takes on the configuration of the now-active appliance and stays in a standby state.
If the vShield Edge appliance is dead, you must delete the appliance and add a new one.
vShield Edge replicates the configuration of the primary appliance for the standby appliance or you can
manually add two appliances. VMware recommends that you create the primary and secondary appliances
on separate resource pools and datastores. If you create the primary and secondary appliances on the same
datastore, the datastore must be shared across all hosts in the cluster for the HA appliance pair to be deployed
on different ESX hosts. If the datastore is a local storage, both virtual machines are deployed on the same host.
vShield Edge ensures that the two HA vShield Edge virtual machines are not on the same ESX host even after
you use DRS and vMotion (unless you manually vMotion them to the same host). Two virtual machines are
deployed on vCenter in the same resource pool and datastore as the appliance you configured. Local link IPs
are assigned to HA virtual machines in the vShield Edge HA so that they can communicate with each other.
You can specify management IP addresses to override the local links.
If syslog servers are configured, logs on the active appliance are sent to the syslog servers.
