Talari Networks, innovator of the most reliable SD-WAN technology, engineers the branch and edge network for maximum business impact, delivering superior application performance and network resiliency, while unlocking the benefits of seamless cloud connectivity services.
Talari T5200 Appliance
The Talari T5200 Appliance is designed for large data centers, branch offices, and call centers with a 10G fiber infrastructure. It has four 10G optical ports and four 10/100/1000 ethernet ports.
The T5200 supports WAN bandwidth aggregation 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.
Talari SD-WAN Controller – Network Control Node (NCN)
The Talari T5200 Appliance can be designated as the Talari SD-WAN master controller, and the central point of administration, for all Talari SD-WAN appliances. The primary purpose of the SD-WAN controller, also called the network controller node (NCN), is to establish and administer conduits to multiple Talari SD-WAN appliances, synchronizing time between appliances, arbitrating end-to-end bandwidth reservations, and establishing dynamic connections between the SD-WAN appliances.
Enterprises are looking to centralize data center services with predictable application performance over a cost-effective WAN infrastructure with high reliability. The Talari T5200 eliminates 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 Talari 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 Talari’s geographic redundancy feature, any Talari Appliance can function as a secondary NCN. 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 NCN for the entire Talari SD-WAN.
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 the case of unforeseen interruptions in a Talari appliance.
SD-WAN Cloud Security
Talari’s jointly validated solution with Zscaler enables Talari SD-WAN edge nodes to transparently forward all Internet traffic to the Zscaler™ cloud over IPsec tunnels, providing a faster user experience, reducing bandwidth costs and simplifying operations. Key features include:
Integrated WAN Optimization
Talari SD-WAN solutions now provide native support for core WAN-optimization features, such as data compression and deduplication of data, in addition to congestion controls. Talari WAN Optimization (WAN-Op) is a composite feature that increases efficiency across the WAN for bulk file-transfer traffic, especially for data requested by more than one user at the same location. By combining WAN-Op with Talari SD-WAN software, organizations can simplify the branch office and create cost efficiencies to network administrators’ IT procurement scope.
