Arista's DANZ capability is a simple and cost-effective approach to aggregating and tapping all traffic across the data center. When there may be a shortage of SPANs or network taps, Arista's precision aggregation enables ExtraHop's real-time analysis of all data in flight. Arista's precision time-stamping and simplified traffic aggregation are key in dynamic environments especially when it comes to software defined networking (SDN).
ExtraHop-Arista Persistent Monitoring Architecture for SDN
As enterprise IT organizations usher in a new era of next-generation software-defined datacenters, ExtraHop and Arista have formed a technology partnership that enables persistent monitoring and cross-tier visibility for these hyper-dynamic environments.
Legacy monitoring tools using inline devices and agents fail with SDN as there is no single point where an inline device can capture all requisite traffic and the provisioning, de-provisioning, and migration of VMs leaves blind spots for agents. Moreover, these products require manual naming and configuration to define applications.
The ExtraHop-Arista Persistent Monitoring Architecture provides a simpler solution that enables persistent, cross-tier operational visibility in dynamic environments. Arista's DANZ capability automatically aggregates a copy of all traffic and ExtraHop, which then automatically discovers, classifies, and maps dependencies of all applications and infrastructure without the use of agents.
The ExtraHop-Arista Persistent Monitoring Architecture capitalizes on DANZ capabilities in the Arista Extensible Operating System (EOS) so that IT teams can programmatically direct traffic to ExtraHop for real-time analysis. This enables IT teams to maintain persistent visibility across all network, infrastructure, and application performance before, during, and after changes to the environment. This persistent and cost-effective monitoring de-risks continuous provisioning, de-provisioning, and migration of VMs.
