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 as a service. Meeting this challenge calls for unification of the management plane to enable holistic management of the data center infrastructure.
™ Data Center Network Manager (DCNM) provides centralized management of both Ethernet and Fibre Channel networks (Figure 1). The converged view enables network and storage administrators to analyze health and performance across the range of platforms running the Cisco NX-OS Software operating system for Cisco Nexus
® and Cisco MDS 9000 Family platforms, regardless of protocol type. Supported protocols and overlays include Fibre Channel, Fibre Channel over Ethernet (FCoE), Ethernet, IBM Fibre Connection (FICON), Small Computer System Interface over IP (iSCSI), Cisco FabricPath, and Cisco Overlay Transport Virtualization (OTV). Cisco Prime DCNM simplifies deployment of SAN and LAN components through wizard- and template-based provisioning and configuration. Role-based access control (RBAC) helps separate configuration of LAN and SAN networks on converged network switches. Support for TACACS+, RADIUS, and Lightweight Directory Access Protocol (LDAP) remote authentication helps organizations control user access to the switches and track changes made by users.

Detailed Summary of Key Main New Features and Enhancements
This section describes the main new features and enhancements in Cisco Prime DCMN 6.2 in detail.
• Highly available scale-out federated architecture: Cisco Prime DCNM adds automatic fabric failover to the scale-out federated architecture, which enables failover from the primary Cisco Prime DCNM federated server to the standby Cisco Prime DCNM server with no loss of fabric visibility. The highly available architecture calls for deployment of a two-node Oracle RAC database on the remote servers along with a shared file system exported to both federated servers. This architecture allows the IT administrator to continuously monitor the network without losing the visibility that is essential to diagnosis of connectivity problems and management of resources.
• VMware vCenter plug-in: The Cisco Prime DCNM plug-in for VMware vCenter adds a multihop view and monitoring of Ethernet and Fibre Channel Cisco Nexus and Cisco MDS 9000 Family topologies to VMware vCenter. 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.
• Heterogeneous storage array support: Heterogeneous array discovery provides visibility from the host down to the logical unit number (LUN) across block- and file-based storage through the storage dashboard. Cisco Prime DCNM also provides a snapshot of capacity utilization and array logical and physical inventory, and it maps the inventory to the hosts connected to the storage array. The feature shows the storage administrator the storage LUN and capacity that is allocated to the server and the access status of the LUN.
• SAN host path redundancy analysis: The SAN host redundancy feature checks against best-practices policy for path redundancy by taking into account configuration of the path, switch, and port status. In addition, Cisco Prime DCNM offers optional path redundancy checks to enhance redundancy correlation all the way down to the LUN by pulling information from the storage array. As a result of heterogeneous storage array discovery, Cisco Prime DCNM can correlate path redundancy down to the storage array LUN, helping ensure that Fabric A and Fabric B server paths are both seeing the same storage devices. Cisco Prime DCNM will list noncompliant hosts and recommend a solution to enable or restore redundancy.
• Cisco Nexus 1000V Switch for Microsoft Hyper-V support: Cisco Prime DCNM adds feature support for configuration, visualization, and monitoring of the Cisco Nexus 1000V Switch for Microsoft Hyper-V. Cisco Prime DCNM now supports Cisco Nexus 1000V Switches on both VMware and Microsoft hypervisors. The user can view the details of the logical networks, segment pools, network segments, and network uplinks as part of the topology and tabular views. The user also can monitor performance and create segments and port profiles on the Cisco Nexus 1000V in the context of Microsoft Hyper-V.
• One-command multiswitch command-line interface (CLI) access: The user can access a global CLI for multiple switches at the same time and view the output on those switches.
• Cisco Nexus 3000 Series Switch buffer use charts and tabular data for microburst monitoring: Cisco Prime DCNM can monitor active buffers on Cisco Nexus 3500 platform on a second-by-second basis and use the monitoring data to present statistics in histogram and tabular views. This feature uses statistics buckets on the switch to enable collection of detailed buffer use data from the low-latency Cisco Nexus 3000 Series Switches.
• On-board Trivial File Transfer Protocol (TFTP) server to enhance archiving and backup: Configuration files can be backed up using the built-in TFTP server rather than requiring installation of a separate Secure FTP (SFTP) server. The TFTP server is embedded in Cisco Prime DCNM.
• Fibre Channel flow wizard enhancement based on end-port traffic utilization: The enhancement to the Fibre Channel flow wizard enables the user to find source devices on the basis of the traffic utilization rate and to add the selected flows to the targets to which those devices are talking. This capability enables the user to customize the utilization threshold rate on the basis of peak rates or averages to identify Fibre Channel flows of interest and configure them for collection.
• Enhanced zone and alias discrepancy report: This report now provides a suggested resolution configuration to fix identified discrepancies. The suggested configuration is presented to the user through a shell script that can be run on the switch directly.
• Redundant SAN fabrics traffic comparison report: This report enables the user to see the distribution of traffic between two fabrics and their end devices. The report helps identify potential multipath software failures and unbalanced redundant links.
• Enhanced event forwarding based on syslog description: This feature allows the user to forward only certain events that match a specified description - for example, port-down events that match a particular interface (for instance, fc1/6) - using a description string or regular expression. A blank description is a wildcard. For example, this feature allows the user to specify event-forwarding rules for certain ports, failure types, and severity levels.
• Enhancement to compute and storage dashboards for multidevice selection: The user can select multiple hosts in compute dashboard or storage arrays in storage dashboard to view aggregate topology and performance for these devices. For example, the user can view the traffic and topology for a specific application cluster in a single view.

Customers with the Cisco Prime DCNM NXACC switch license under a valid service contract should follow the additional guidance in Table 2.
Table 2. Customers Upgrading with Cisco Nexus Access Switch License
Customers with Cisco Prime DCNM NXACC switch license under valid service contract:
The Cisco Prime DCNM NXACC advanced feature licenses are neither recognized nor supported by Cisco Prime DCNM 6.x releases. No license is required in Cisco Prime DCNM 6.xx for management of the Cisco Nexus 2000 Series Fabric Extenders and 4000 Series Switches or Cisco Nexus 1000V Series Switches, but users must upgrade to replacement Cisco Prime DCNM LAN Cisco 5000 Series Switch licenses to use Cisco Prime DCNM 6.x to manage Cisco Nexus 5000 Series Switches.
