Black Box iPATH ACR1000A-CTL-24 User Manual page 26

4.5.7 DASHBOARD > SETTINGS > SERVERS
This page is used to configure redundant operation for the iPATH servers.
Two or more servers can be added onto the same subnet or Vlan. One iPATH box is the Primary (or Master) the other is the
Backup (or Slave). If the Primary server fails for any particular reason then the Backup will take over until the Primary is repaired.
This functionality is only possible if the licenses of the both iPATH units match. Both iPATH units need to be able to control the
same number of endpoints.
When in Multi-subnet mode it is possible to place additional servers on a different subnet or Vlan. These servers are reffered to
as satellites.
Primary Timeout
The time (in seconds) for the Primary server to be unavailable before the Backup takes over.
Quiescent Timeout
The time after which an inactive (Quiescent) server is assumed to have disappeared.
Backup Check Interval
The interval between the Primary server querying its backups to determine if they are all on-line.
Backup Timeout
The period of time that a backup server can be off line or uncontactable before it is treated as a failed server.
Require Authentication
If set to 'Yes', then a new, unconfigured iPATH server will be unable to join the cluster automatically; it's behaviour will be to
report itself as unconfigured and quiescent, and request a password. Entering the cluster password will then allow it to join the
cluster as a Backup.
Cluster Password
This is the password that is used for iPATH-to iPATH https queries, if the Require Authentication option is enabled.
