System Requirements for Cisco DCNM
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. |
This section describes the various system requirements for proper functioning of your Cisco DCNM, Release 11.2(1).
Java Requirements
The Cisco DCNM Server is distributed with JRE 1.8.0_201 into the following directory:
DCNM_root_directory/java/jre1.8
Server Requirements
Cisco DCNM, Release 11.2(1), supports the Cisco DCNM Server on these 64-bit operating systems:
-
SAN Deployments:
-
Microsoft Windows 2016
-
Microsoft Windows 2012 R2
-
Red Hat Enterprise Linux Release 7.3, 7.4, and 7.6
-
-
IP for Media, LAN Fabric, and Classic LAN Deployments:
-
Open Virtual Appliance (OVA) with an integrated CentOS Linux release 7.6
-
ISO Virtual Appliance (ISO) with an integrated CentOS Linux release 7.6
-
Cisco DCNM Release 11.2(1) supports the following databases:
-
Oracle11g Express (XE), Standard, and Enterprise Editions, and Oracle 11g Real Application Clusters (RAC)
-
Oracle 12c Enterprise Edition (Conventional)—(Nonpluggable installation)
Note
Cisco DCNM Release 11.2(1) does not support the Oracle 12c pluggable database version installation.
-
Oracle 12c RAC (nonpluggable installation)
-
PostgreSQL 9.4.5
Note |
The ISO/OVA installation only supports the embedded PostgreSQL database. |
Note |
The Cisco DCNM database size is not limited. The database size 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 an 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 backup of the database; either daily or weekly, to ensure that all the data is preserved. |
Cisco DCNM Release 11.2(1) supports the ISO installation on a bare-metal server (no hypervisor) on the following server platforms:
Server |
