Talari Appliance T5000
Designed to bring WAN reliability and higher bandwidth to large data centers and call centers, the 2U rack-mountable Talari Appliance T5000 supports aggregation of WAN bandwidth up to 3 Gbps uplink/3 Gbps downlink (3 Gbps full-duplex)
Additionally, the T5000 runs the same software as the other models, supporting gigabits of WAN bandwidth across the union of private WAN links and public Internet connections and providing support for a vastly larger number of branch connections and application flows.
Network Control Node (NCN)
The Talari Appliance T5000 acts as the master controller of the Talari-enabled WAN and the central point of administration for the client nodes. The network control node’s primary purpose is to establish and utilize a conduit with one or more Talari client nodes across the network for enterprise site-to-site communications. A particular network control node can administer and have conduits to multiple client nodes.
For enterprises looking to centralize more services at their data centers, predictable application performance over a cost effective WAN infrastructure and high reliability are key requirements. The Talari T5000 Appliance high-availability functionality eliminates the Talari appliance as a single point of failure in the network by providing complete redundancy between two Talari appliances. The pre-designated “standby” appliance monitors the state of the “active” appliance and, in the event of a failure, takes over all appliance services. Using a specialized protocol, the Talari high availability system can detect a failure in the active appliance and switch over all functions to the standby appliance in a fraction of a second, in a way that is transparent to most active applications.
With the geographic redundancy feature, any other Talari appliance can also function as a secondary network control node. In the event of a primary data center failure, the backup data center should be operational and the secondary Talari appliance would act as the network control node for the Talari-enabled network.
The T5000 appliance include four pairs of fail-to-wire ports, automatically enabling a passive pass-through mode even in case of unforeseen interruptions in a Talari appliance.
