Availability
ExtremeCloud Appliance provides the availability feature to maintain service availability in the event of
an outage. The Availability Pair feature allows both AP and Client statistics to be available on both sides
of the High Availability configuration.
Go to Admin > System > Availability and configure the Availability Pair settings.
Availability
•
Standalone. The appliance does not have an availability partner in the event of a failover.
•
Paired. The appliance is paired with another appliance in the event of a failover.
When configuring an Availability Pair consider the following information:
•
ExtremeCloud Appliance directly balances capacity allocations across both appliances in an
Availability Pair. Adoption Capacity is additive. For example, to support a 600 AP Capacity, you can
purchase a 500 Device Capacity (30330) and a 100 Device Capacity (30329). The Availability pair
shares the installed capacity to the 600 limit. You can enter the entitlements on either system in the
pair. However, when purchasing capacity license SKUs, make sure that none of the license blocks
exceed the maximum adoption capacity for any individual system.
•
Availability pair can be configured only within the same ExtremeCloud Appliance models.
•
Enable and configure NTP: Network Time settings on each appliance of an Availability Pair must be
identical for the configuration update process to be successful.
•
Use the Network Health chart on the ExtremeCloud Appliance Dashboard to Monitor the Availability
Link Status and the Synchronization Status for an Availability Pair.
•
Switch configuration and statistics are synchronized between the primary and backup
ExtremeCloud Appliance.
The following status data is replicated on the partner node of an Availability Pair:
•
Client Records
•
Group Records
