Modern data centers are becoming increasingly massive and complex. Proliferation of new technologies such as virtualization is adding yet another level of complexity while enabling higher workloads to be placed on the network. Innovations such as Cisco
® Unified Fabric unify storage and data networking to deliver convergence, scalability, and intelligence with reduced total cost of ownership (TCO) and faster return on investment (ROI). IT departments today are challenged to look beyond traditional silos of networking and storage to manage this converged, virtualized data center. Meeting this challenge calls for unification of the management plane to enable holistic management of the data center infrastructure.
™ Data Center Network Manager (DCNM) combines management of both Ethernet and storage networks in a single dashboard. The dashboard enables network and storage administrators to troubleshoot health and performance across the whole range of Cisco NX-OS Software platforms, including the Cisco Nexus
® and Cisco MDS 9000 Families, regardless of protocol type such as Fibre Channel, Fibre Channel over Ethernet (FCoE), Ethernet, IBM Fibre Connection (FICON), and Small Computer System over IP (iSCSI). By using Cisco DCNM, IT administrators can identify available port capacity, reclaim orphaned ports, and maintain inventory of logical and physical switch components. Cisco DCNM also simplifies deployment SAN and LAN components by providing wizard- and template-based provisioning and configuration. Role-based access control (RBAC) helps separate configuration of LAN and SAN networks on converged network switches. DCNM supports TACACS+, RADIUS, and now Lightweight Directory Access Protocol (LDAP) remote authentication protocols to help manage user access to switching infrastructure.
™ DCNM can be licensed for SAN and LAN environments separately or together. Majority of DCNM features used for provisioning and discovery are available for free with base image (essentials edition) while advanced features need an advanced edition license to unlock. DCNM is priced by switch platform and licensed per number of switches. In addition yearly service contract is required to upgrade from one major release to another.
The remainder of this document summarizes the Cisco Prime
™ DCNM features.

Features and Benefits
™ DCNM offers a number of features and benefits for the data center, discussed here and summarized in Table 1.
Virtual Machine-Aware Path Management
™ DCNM extends network visibility to virtual infrastructure by mapping the entire path from the virtual machine and switch to the physical storage and Ethernet networks. The Cisco VMpath feature that is part of the host dashboard provides views to help troubleshoot the performance of a virtual machine and virtual host while also reporting on the health and performance of the network and storage paths. The virtual machine-aware dashboard displays performance charts, path attributes, topology, path alerts, and information about the utilization of virtual machines and virtual hosts (Figure 2). The increased visibility into virtualized infrastructure helps IT administrators locate performance anomalies that may be causing service degradation as well as eliminate virtual computing and networking as a root cause of the problem.
Figure 2. VMpath View Extends to Storage and Ethernet Networks
Planning: Performance Trending and Forecasting
By analyzing historic performance and projecting future bandwidth consumption, Cisco Prime
™ DCNM helps IT departments understand the baseline traffic pattern for a deployed application and identify any performance anomalies that may affect customer service levels. Cisco Prime
™ DCNM also helps IT design teams plan new deployments and redesign existing deployments based on peak utilization information collected as far back as a year or more. By monitoring historic performance, the design team can optimize switch consolidation activities by choosing modules with higher port densities based on the performance of applications, thus reducing the need to deploy more switches, reducing power utilization, and leaving more tile space in the data center for computing and storage resources (also shown in Figure 2).
Troubleshooting: Event Management
™ DCNM consolidates all the events on the network, such as threshold breaches and switch and path alerts, and tracks configuration changes by individual network and storage administrators that may have caused outages or performance degradation. In addition, the Cisco Prime
™ DCNM event-forwarding mechanism notifies, in real time, the appropriate email address, pager, or third-party management application when predefined thresholds are breached or the health of the network affected (Figure 3). The IT administrator can then acknowledge the alert in the event dashboard and, after the problem is resolved, delete the alert.
Figure 3. Enhanced Event Management
Through the concept of domain dashboards, Cisco Prime
™ DCNM creates contextual views of the host, switch, and storage infrastructure (Figure 4). These views help IT administrators identify individual components and display their health and performance attributes. In addition, Cisco Prime
™ DCNM provides a search engine that launches these dashboards in the context of the search attributes. IT administrators can in seconds determine the source of a network problem, thus reducing the outage time or preventing an outage from occurring in the first place.
Figure 4. Switch and Storage Dashboards
Configuration and Provisioning: Web Templates
™ DCNM provides IT administrators with wizards and predefined scripts for deploying configuration changes to Ethernet and storage networks (Figure 5). Wizard-based provisioning guides IT staff through the provisioning of hosts, Inter-Switch Links (ISLs) and trunks, and storage ports, regardless of whether the ports reside on the physical or virtual Cisco switch. In addition, Cisco Prime
™ DCNM provides predefined template scripts for common tasks, which administrators also can customize; administrators also can import their own scripts into template formats and store them in the template repository.

Capacity Manager: Managing Port Capacity by Tier
Understanding resource consumption is essential to increase throughput of applications and projects into the data center. To help prevent the Ethernet or storage network from becoming a bottleneck in this process, Cisco Prime
™ DCNM helps track port utilization by tier, and through trending capacity manager predicts when an individual tier will be consumed (Figure 6). The information provides the capacity management team with enough time to order more ports or switches, thus reducing the risk that the network will become a bottleneck for application and project throughput. Increased throughput allows organizations to grow at a quicker pace, while reducing operational and capital expenses and most importantly improving overall customer experience.
Figure 6. Managing Port Capacity by Tier
The new release of Data Center Network Manager joins Cisco Prime Infrastructure family of management products on the journey to unify management of Cisco Data Center, Campus, and Collaboration-driven networks.
Cisco Prime is an innovative strategy and portfolio of management products that empower IT departments to more effectively manage their networks and the services they deliver. Cisco Prime is built upon a network services management foundation and a set of common attributes. It delivers an intuitive workflow-oriented user experience across Cisco architectures, technologies, and networks. Cisco Prime simplifies network management, improves operations efficiency, reduces errors, and makes the delivery of network services more predictable.
Data center management tools must scale to meet the needs of large and distributed data center deployments. Customers do not want to spend time switching between multiple servers and dashboards. Prime DCNM maintains a consolidated view of the entire network by leveraging scale-out node architecture. As a result, network operations centers (NOCs) can now have a single dashboard for monitoring network alerts and events across multiple data centers.
