Here are some examples of the untenable problems facing network administrators: Never before have the challenges of maintaining visibility into the inner workings of the datacenter network been as great as they are today. Lack of visibility facing IT operations teams continues to grow with the addition of high-density server virtualization, multi-tenant cloud environments and big data applications like Hadoop. In effect, many IT organizations have conceded that they are “flying blindfolded” to the actual traffic patterns in their datacenter. The challenges of examining and analyzing massive amounts of data to diagnose network problems, troubleshoot applications, assure performance and secure the modern datacenter are becoming insurmountable with traditional technology. With the introduction of the Arista 7280R and 7500R-series switches, Arista has now extended the Universal Leaf and Spine use cases to monitoring with the DANZ feature set on EOS. DANZ can be further enhanced by leveraging Arista CloudVision® for automation, provisioning and monitoring of the visibility infrastructure, whether implemented in-band in the production network or out-of-band for a separate visibility network. DANZ provides a solution to monitoring and visibility challenges at 10 to 100Gbps and higher with unmatched scale, price performance and bandwidth. Automate configuration and management of the monitoring infrastructureĪrista Data ANalyZer (DANZ) is an integrated feature set in Arista’s Extensible Operating System and is currently available on Arista Networks 7150-series, 7280SE-series, 7500E-series, 7280R-series and 7500R-series switches.Manage overall customer satisfaction and response times.Perform traffic interception when required such as for Lawful Intercept.Troubleshoot applications and performance problems.Maintain security, compliance and reporting for all types of traffic.The challenge remains in that IT organizations have requirements to perform the following functions with increasingly higher data volumes and higher network bandwidths, while controlling or reducing costs: Owing to the large volumes of traffic, traditional methods of capturing and analyzing traffic flows require a dramatic rethink in density and performance for data aggregation and visibility. To handle these loads, deployments of multi-path 100Gbps Ethernet spine and leaf architectures are becoming the norm. A single application or storage server, now connecting at speeds of 10Gbps, 25Gbps and even 50Gbps, can now generate bi-directional flow rates in excess of tens of billions of packets per day with aggregate daily traffic in many cloud data centers measurable in petabytes and beyond. Traffic volumes are exploding in the datacenter due to the increasing efficiency and density of highly-virtualized cloud computing infrastructures.
