System Requirements for Cisco DCNM, Release 11.0(1)
Note |
We recommend that you do not upgrade any underlying third-party software separately. All the necessary software components will be updated during the inline upgrade procedure. Upgrading the components outside of DCNM upgrade will cause performance issues. |
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

-
Red Hat Enterprise Linux Release 7.3 and 7.4
-
-
LAN Fabric, Classic LAN, and IP For Media (IPFM) Deployments:

Note |
Cisco DCNM 11.0(1) for LAN is not supported with an external database. |
Note |
The ISO/OVA installation only supports the embedded PostgreSQL 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. If you choose Oracle database, we recommend that you use Oracle SE or Enterprise edition, instead of Oracle XE due to table space limitations. |
Note |
You are responsible for all the support that is associated with the Oracle databases, including maintenance, troubleshooting, and recovery. We recommend that you take regular database backups, either daily or weekly, to ensure that all the data is preserved. |
Cisco DCNM Release 11.0(1) supports the ISO installation on a bare-metal server (no hypervisor) on the following server platforms:1
