Cisco DCNM Web UI

Cisco DCNM Web UI allows operators to monitor and obtain reports for Cisco MDS and Nexus events, performance, and inventory from a remote location using a web browser. Licensing and discovery are part of the Cisco DCNM Web UI.

Performance Manager

Performance Manager presents detailed traffic analysis by capturing data with SNMP. This data is compiled into various graphs and charts that can be viewed on the Cisco DCNM Web UI. Performance Manager stores data into Elastic search time series database. API access to Elastic search is not supported.

collection will backup files on Elastic Search which aids in better scalability and API access.

Standalone Server

All types of installers are packaged along with PostgreSQL database. The default installation steps for the respective installers result in this mode of deployment.

High Availability for Virtual Appliances

The DCNM Virtual appliances, both OVA and ISO, can be deployed in High Availability mode to have resilience in case of application or OS failures.

Java Requirements

The Cisco DCNM Server is distributed with JRE 1.8.0_152 into the following directory:

DCNM_root_directory/java/jre1.8

Server Requirements

Cisco DCNM, Release 11.0(1), supports the Cisco DCNM Server on these 64 bit operating systems:

• LAN Fabric, Classic LAN, and IP For Media (IPFM) Deployments:

  • Open Virtual Appliance (OVA) with integrated Operating System

  • ISO Virtual Appliance (ISO) with integrated Operating System

Cisco DCNM Release 11.0(1) supports the following databases:

• PostgreSQL 9.4.5

Note	Cisco DCNM 11.0(1) for LAN is not supported with an external database.

Note	The ISO/OVA installation only supports the embedded PostreSQL database.

Note	The Cisco DCNM database size is not limited, and increases according to the number of nodes and ports that the DCNM manages with Performance Manager Collections enabled. You cannot restrict the database size.

Cisco DCNM Release 11.0(1) supports ISO installation on a bare-metal server (no hypervisor) on the following server platform:

Note	Cisco DCNM can work on alternative computing hardware as well, despite Cisco is only testing on Cisco UCS.

Cisco DCNM Release 11.0(1) supports the running of the Cisco DCNM Server on the following hypervisors:

• VMware ESXi 5.5

• VMware ESXi 6.0

• VMware ESXi 6.5

• VMware ESXi 6.7

• VMware ESXi 6.7 U1

• VMware vCenter 6.0

• VMware vCenter 6.5

• VMware vCenter 6.7

• VMware vCenter 6.7 U1

Note

vCenter server is mandatory to deploy the Cisco DCNM OVA Installer. When you log into the VMware vSphere Web Client, the Adobe Shockwave Flash crashes with the latest Google Chrome 62.0.3202.62 (64 bit), Mozilla Firefox 56.0.1 (64 bit), and Internet Explorer 8.0.7601.17514. Hence you cannot install Cisco DCNM on VMware ESX using VMware vSphere Web Client. This is a known issue with Adobe Shockwave Flash version 27.0.0.159.
