Virtualization and cloud technologies present exciting opportunities for business transformation, innovative services delivery models, and improved economics. At the same time, they introduce a new dimension of application delivery challenges. To take advantage of the new paradigm, it is essential to have comprehensive application intelligence and deeper visibility into the network technologies that form the foundation of the fabric of the next-generation data center.
The Cisco Nexus® 7000 Network Analysis Module (NAM-NX1) is a high-performance services module (Figure 1) that offers comprehensive application awareness, rich performance analytics and deeper network visibility to simplify data center operations. It empowers network administrators with actionable details to characterize application experience, optimize use of network resource, and troubleshoot performance issues, improving service delivery in today's dynamic IT environment.
Integrated with Cisco Nexus 7000 Switches, the Cisco NAM-NX1 delivers the visibility you need to take maximum advantage of the fabric for efficient service delivery in a distributed environment. It helps you to:
• Monitor application experience and isolate the cause of latency in the event of performance degradation.
• Gain deeper insight into virtualization and overlay technologies such as OTV, LISP, and VXLAN to optimally design the network for distributed and efficient services delivery. For instance, in OTV environments, Cisco NAM-NX1 can look inside each overlay to provide traffic statistics, application performance metrics, and their breakdown by host, applications, conversations, and ways to help you analyze and ensure effective use of these technologies.
• Accelerate troubleshooting with interactive reports and purpose-built workflows; you can analyze data in the context of the specific application, site, client, and server; and extend visibility consistently across physical and virtual environments.
• Preserve investment in existing management assets, supporting integration using standards-based API.
Designed to meet the rigorous demands of the data center, Cisco NAM-NX1 takes advantage of leading edge hardware and backplane integration with the Cisco Nexus 7000 Series chassis. The integration provides greater investment protection, lower total cost of ownership (TCO), improved power management, and reduced the network footprint saving premium rack space. It also enables collection of packets from the backplane, continuously or on demand, ensuring high reliability and accurate analytics.
Cisco Nexus 7000 NAM-NX1 Features and Benefits
The Cisco Nexus 7000 NAM-NX1 offers an extensive set of features that provide a multidimensional view into network and application performance to help you successfully tackle the service delivery challenges in today's dynamic IT environment (Table 1).
Table 1. Cisco Nexus 7000 NAM-NX1 Features and Benefits
Advanced application performance analytics
Characterize the application experience for TCP-based applications and isolate application response-time problems to the network, server, or application, to accelerate troubleshooting.
Application traffic analysis
View short-term and long-term network utilization by application, host, conversation, Differentiated Services Code Point (DSCP) group, and various overlay network technologies so you can make better network resource allocation decisions.
IEEE1588-based time synchronization
Packet capture from the backplane combined with a precise hardware time stamp improves accuracy of performance measurements such as Jitter, application response time. The IEEE 1588 hardware time stamps also facilitate accurate packet capture analysis when merging captures from multiple NAMs to investigate complex application performance problems.
Visibility into Cisco OTV
Maximize the benefits of Cisco OTV-based extended Layer 2 implementations across data centers. The Cisco NAM deployed with Cisco Nexus 7000 Series Switches lets you profile traffic and troubleshoot OTV deployment problems.
Cisco TrustSec® policy validation
Validate Cisco TrustSec policy by using security group tags (SGTs) and evaluating the endpoints and hosts, applications, and conversations participating in one or more security groups.
Insight into Data Center Protocols
Design Data Center overlay networks for optimal delivery of distributed applications. Supported protocols include OTV, LISP, MPLS, VXLAN, etc.
Comprehensive voice quality monitoring and real-time troubleshooting
Gather real-time reports on mean opinion scores (MOSs) and other key performance indicators (KPIs) such as jitter and packet loss to understand and improve the way that the end user experiences the delivery of voice services. MOS is computed based on ITU-T Recommendation G.107, offering accurate characterization of voice quality. Combine monitoring with real-time troubleshooting using prepackaged dashboards to improve end-user service levels.
WAN-optimized network visibility
Obtain end-to-end proof points demonstrating how Cisco Wide Area Application Services (WAAS) has improved application delivery (for example, decreased application transaction times and improved WAN bandwidth utilization). Accelerate return on investment (ROI) by assessing the best site and application candidates for optimization as part of a phased rollout plan.
Deep, insightful packet analysis
Solve complex performance problems with trigger-based captures, scheduled captures, filters, decodes, and error scan features. Packet captures can be triggered based on performance thresholds, allowing you to focus on specific performance concerns. In addition, you can use external storage to collect extensive packet captures for offline analysis.
Advanced hardware and software filters
Reduce the time to gather critical network data, accelerating troubleshooting and analysis of network traffic behavior. Examples of the filter includes: MPLS label, VLAN ID, Frame length, L4 Protocol, Pattern Match.
Preserve investment in existing management assets through integration based on a standards-based REST/XML) application programming interface (API).
