In this era of digital transformation and business resiliency, continuous innovation is critical for organizations to succeed, and experiencing downtime along the way is not an option. Users increasingly demand more features and better usability, reliability, and environmental sustainability from the applications they use.
The network plays a huge role in meeting such demands, and provisioning reliable data-center and cloud-networking services as fast as possible, when and where organizations need them, is a must. However, network infrastructure management is becoming more complex, diverse, and distributed, with multiple configuration points, monitoring tools, and vast amounts of data being generated every second (Figure 1).
Cisco Nexus Dashboard software does not require an additional license and it is included with all Cisco Nexus 9000 switch tiered-license purchases. Cisco Nexus Dashboard provides a single focal point to unite disparate network configurations and views of multiple switches, data centers, and clouds (Figure 2). Through its Insights service, network operators can now accelerate time to resolution and preserve compliance in their networks by leveraging years of Cisco knowledge hosted on Nexus Dashboard’s analytics engine.
Cisco Nexus Dashboard and services
Cisco Nexus Dashboard Insights supports Cisco® Application Centric Infrastructure (Cisco ACI®), standalone Cisco NX-OS switches, and networks with Cisco Nexus Dashboard Fabric Controller (NDFC). It is a microservices-based service natively hosted on Cisco Nexus Dashboard.
The operational intelligence engine of Cisco Nexus Dashboard Insights incorporates a set of advanced alerting, baselining, correlation, and forecasting algorithms to provide deep insights into the behavior of the network by utilizing telemetry data obtained from networking and compute components.
Cisco Nexus Dashboard: Operational intelligence engine
Cisco Nexus Dashboard Insights accelerates troubleshooting and helps rapid root-causing and early remediation. Compliance rules keep the network state aligned with operator intent. It simplifies audits and ensures compliance while also helping infrastructure owners comply with SLA requirements for their users.
Nexus Dashboard provides a cluster of compute nodes that are horizontally scalable. The sizing and number of compute nodes required for Nexus Dashboard Insights depends on the number of sites, the number of switches in each site, and the workflows per second that the users want the application to support.
