Talari Appliance T5200
The Talari Appliance T5200 is designed for data centers and large branch offices with a 10G fiber infrastructure. It has four 10G optical ports and four 10/100/1000 ethernet ports.
T5200: designed for large data centers and call centers, the T5200 supports an aggregation of WAN bandwidth up to 5 Gbps uplink/5 Gbps downlink (5 Gbps full-duplex), two sets of fail-to-glass 10G optical ports, and two sets of fail-to-wire ethernet ports
Network Control Node (NCN)
The Talari Appliance T5200 can be designated to act as the master controller of the Talari Software Defined WAN and the central point of administration for the client nodes. The network controller’s nodes primary purpose is to establish and utilize a conduit with one or more Talari client nodes across the network for enterprise communications. A particular network control node can administer and have conduits to multiple client nodes. The controller synchronizes time between appliances as well as helps arbitrate end to end bandwidth reservations, and establishes dynamic connections between client appliances.
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 T5200 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 T5200 appliances include two pairs of fail-to-wire ports and two pairs of fail-to-glass ports, automatically enabling a passive pass-through mode even in case of unforeseen interruptions in a Talari appliance.
