Cisco Data Center Network Manager (DCNM) for SAN simplifies management of the virtual infrastructure by enabling management of the entire path through the physical to the virtual network across the whole data center environment. The VMpath views increase service availability by identifying bottlenecks in virtual machine and VMware ESX performance and extending visibility to the physical fabric. The virtual machine-aware (VM-aware) topology view shows all the dependencies from the virtual machine out to the physical host, through the fabric, and to the storage array with easy access to a detailed view of the path attributes. The VM-aware dashboard displays all the information needed to manage the virtual environment including performance charts, inventory information, events, and virtual machine and VMware ESX utilization information. Cisco DCNM for SAN maps paths all the way from the server to storage, enabling tracking of mission-critical workloads across the entire network.
Cisco DCNM for SAN helps IT ensure the resiliency of the Cisco SAN infrastructure by monitoring and providing alerts for fabric availability and performance. It provides near-real-time monitoring of fabrics with visibility into traffic spikes and establishes baseline traffic patterns. When predefined thresholds are breached, appropriate alerts are generated and can be forwarded to operations staff and enterprise operations consoles for incident management.
It provides real-time network health summary with detailed view of individual network components, enabling operations staff to respond quickly to events based on their severity and facilitates early detection and prevention of outages, increasing network availability.
Performance and capacity
It provides detailed visibility into real-time and historical performance statistics in the data center and insight into port and bandwidth utilization, error count, traffic statistics.
It provides view of VMpath through physical fabric to storage array and to the data store and capability to view performance for every switch hop all the way to the individual VMware ESX server and virtual machine.
It displays real-time operationally focused topology of the data center infrastructure and offers layer 2 topology maps to streamline the troubleshooting process and reduce the mean time to repair; mouse over topology to view detailed information about paths and switch attributes.
It lets you build custom reports from predefined templates across all fabrics, individual fabric, or VSANs and provides easy-to-schedule reports that can be exported for post processing or sent by email.
Using automated network discovery, it provides up-to-date physical and logical inventory information and tracks inventory and performance information in real time; information can be used as a source of truth for asset tracking or as a data source for a configuration management database (CMDB).
Configuration and change management
It provides pre-deployment validation of configuration changes, reducing opportunities for human error. Using historical configuration archive coupled with config-compare, enables you to identify the last-known good state if configuration problems occur.
