As mission-critical workloads migrate to virtual servers, visibility into the virtual switching infrastructure
becomes critical to manage end-to-end service delivery. The virtual switching layer extends the network
to the virtual servers. Lack of insight into this layer affects the ability of network administrators to manage
application services. In addition, the fluidity of the virtual infrastructure, in terms of workload-driven
dynamic resource allocation or virtual server migrations across hosts, poses a new set of management
challenges. In this dynamic environment, network administrators are not only responsible for
troubleshooting application performance issues but also for making sure that the network is ready to
support resource scaling in real time. This demands deeper network visibility and analytics to present
meaningful and consistent performance information for network administrators.
Product Overview
Cisco Nexus 1000V Network Analysis Module (NAM) Virtual Service Blade (VSB) allows network administrators to
extend operational visibility into Cisco Nexus 1000V Switch deployments (Figure 1). The Cisco Nexus 1000V Switch
is a software switch on a server that delivers Cisco Virtual Network Link (VN-Link) services to virtual machines (VMs)
hosted on that server. This distributed switch has two major components: the Virtual Ethernet Module (VEM) and the
Virtual Supervisor Module (VSM), which manages the VEMs. A VSM can itself be deployed as a virtual machine; as
Modules.
Integrated with the Cisco Nexus 1010 appliance, the Cisco NAM VSB offers combined network and application
performance visibility essential to address service delivery challenges in next-generation data centers. The Cisco
NAM VSB allows you to effectively use embedded management features, such as Encapsulated Remote Switched
Port Analyzer (ERSPAN) and NetFlow, on the Cisco Nexus 1000V Switch to:
●
Analyze network usage behavior by application, host/VM, and conversation to identify bottlenecks that may
affect performance and availability
●
Troubleshoot performance issues with extended visibility into VM-to-VM traffic, virtual interface statistics, and
transaction response times
●
Assess impact on network behavior due to changes such as VM migration, new application deployment, and
port profile update
●
Improve the efficiency of your virtual infrastructure and distributed application components with
comprehensive traffic analysis
As a distinctive advantage, Cisco NAM allows you to monitor the network and virtual machines uninterrupted by
VMotion operations.
