Product Overview

Modern data centers are becoming increasingly large and complex. New technology architectures such as cloud computing and virtualization are adding another level of complexity to the data center management plane. Today's IT departments are challenged to meet the business needs for scalability, flexibility, and agility in deploying and managing new technologies and services in the data center. To address this challenge, they depend on a variety of tools from numerous vendors to manage different parts of the network, which results in limited views of different parts of the data center and a lack of a holistic view of the health and performance of the overall infrastructure.
Cisco ® Data Center Network Manager (DCNM) is a Cisco management solution that increases overall data center infrastructure uptime and reliability, improving business continuity. Focused on supporting efficient operations and management of the data center network, Cisco DCNM provides a robust framework and rich feature set that meets the routing, switching, and storage administration needs of present and future data centers. In particular, Cisco DCNM automates the provisioning process, proactively monitors the SAN and LAN by detecting performance degradation, streamlines the diagnosis of dysfunctional network elements, and secures the network. Offering an exceptional level of visibility and control through a single pane to Cisco Nexus ® and Cisco MDS 9000 Family products, Cisco DCNM is the Cisco recommended solution for mission-critical data centers.

Features and Benefits

Innovative data center technologies, mainly related to network and server virtualization, are built into the Cisco Nexus Family platforms. Virtual device context (VDC), virtual PortChannel (vPC), Cisco FabricPath, and port profile technologies are powerful new networking constructs and create challenges from a management perspective. Cisco DCNM is built to provide visibility into these features, helping remove deployment hurdles and monitor their health.

VDC: Cisco DCNM enables network virtualization by creating VDCs, facilitating resource allocation across VDCs and providing independent management for each VDC. VDCs are managed transparently throughout the application; the role-based access control (RBAC) model and topology maps are VDC aware.

vPC: Cisco DCNM fully automates vPC operations. Two vPC peers can be managed as one logical device, allowing enforcement of the vPC peer configuration synchronization policy. Configuration mismatches between the primary and secondary vPC peers are prevented during the initialization phase, and vPC policy compliance is monitored on an ongoing basis. If an inconstancy is detected, it can be automatically repaired, bringing the network back to an operational state.

Cisco FabricPath: Because of the dynamic nature of Cisco FabricPath, which auto-regulates the traffic load across Layer 2 multiple paths, the operations team must get visual feedback as to where and how traffic is actually traversing the fabric. A dedicated Cisco FabricPath topology view with unicast, multicast, and broadcast graphs provides this visibility (Figure 1). The path taken by the traffic between two edge switches is identified. When the return path is different from the entry path, the return path is also clearly identified. An easy-to-use, prebuilt template enables quick, error-free provisioning of Cisco FabricPath across the data center fabric.

Cisco DCNM proactively measures bandwidth consumption and traffic patterns in the network, enabling early identification Cisco FabricPath hotspots, and thus congestion can be circumvented. The health of a Cisco FabricPath domain can be measured in real time for better service delivery.

Table 1 summarizes the main features and benefits of Cisco DCNM 5.1.

Table 1. Features and Benefits



Operational Monitoring of Data Center Infrastructure

Proactive monitoring

• The overall network health is summarized in a scoreboard-type interface, with at-a-glance, real-time, color-coded status information about all the faults in the data center.
• Monitoring facilitates early detection and prevention of outages, increasing network availability.
• There are no rules to write; monitoring works out of the box with prebuilt rules and thresholds.

Performance and capacity

• Get visibility into real-time and historical performance statistics in the data center.
• Gain insight into port and bandwidth utilization, error count, traffic statistics, security violations, etc. Reports can be offloaded for postprocessing.
• Get visibility into hardware resource utilization, ternary content addressable memory (TCAM) statistics, and environmental resource utilization information such as power draw and temperature.

Topology views

• View the real-time operationally focused topology of the data center infrastructure.
• Accurate stateful Layer 2 topology maps streamline the troubleshooting process and reduce the mean time to repair (MTTR).
• Technology-specific overlays for vPC, Cisco FabricPath, VDC, and VLAN enable provisioning and efficient management of these features.

Data Center Resource Management

Automated discovery

• Automated high-fidelity network discovery provides up-to-date physical and logical inventory information at a glance.
• Inventory information is tracked continuously and can be used as a source of accurate network asset and configuration information that can be integrated into configuration management databases (CMDBs).

Configuration and change management

• Pre-deployment validation of configuration changes based on domain rules reduces chances of misconfiguration.
• Out-of-the-box configuration wizards are provided for critical Cisco NX-OS Software features such as vPC, VDC, and Cisco FabricPath.
• Historical configuration archive coupled with configuration comparison and granular rollback enables an organization to return to a previously known good state in case of configuration problems.

Template-based provisioning

• Accelerate service rollout by using parameterized prebuilt templates for critical Cisco NX-OS features.
• Roll out bulk configuration changes with templates on demand or on a specified schedule.
• Templates help ensure consistency in configurations and reduce the likelihood of operator errors and mis-configuration.
• Multiple administrators can create, edit, and share templates across the entire operating staff.

Image management

• Easy-to-use, non-disruptive In-Service Software Upgrade (ISSU) mass deployment of Cisco NX-OS images can be scheduled or run on demand.
• Image upgrades are pre-validated, helping ensure compatibility with the running configuration, and in the event of a failure, rollback is initiated automatically.

Integration with Enterprise Systems

Web services APIs

• Abstract the network to implement IT service management frameworks and CMDB integration.
• Easy integration with third-party applications allows accurate flow-through provisioning and data mining.
• Out-of-the-box integration & coresidency with Cisco Fabric Manager.

Event forwarding

• Integrate with the enterprise network operations console (NOC) for alerts and events.
• Use email and alerts to notify operations staff of critical outages that may be service-impacting.
