The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter lists the tested and supported hardware and software specifications for Cisco Prime Data Center Network Management (DCNM) server and client architecture. The application has been tested in English locales only.
This section includes the following:
The Cisco Prime DCNM Server is distributed with JRE 1.7.0_72 or later. The Cisco Prime DCNM installer installs JRE 1.7.0_72 into the following directory:
DCNM_root_directory/java/jre1.7
Cisco Prime DCNM client is supported on JRE 1.7.0_76 or a later 1.7 version.
Cisco Prime DCNM, Release 7.2(x), supports the Cisco Prime DCNM Server on these operating systems:
Microsoft Windows 2008 R2 SP1
Microsoft Windows 2008 Standalone SP2
Microsoft Windows 2012 R2
Red Hat Enterprise Linux Release 5.6 and 5.7
Red Hat Enterprise Linux Release 6.3 and 6.4 (64-bit)
OVA and ISO with integrated operating system
Cisco Prime DCNM, Release 7.2(x), supports the following databases:
Oracle 10g, Oracle11g Express (XE), Standard, and Enterprise Editions, and Oracle 11g Real Application Clusters (RAC)
PostgreSQL 9.4
High-Availability internal database with Release 7.2(x)
Oracle 12c Enterprise Edition (Conventional)–(nonpluggable installation)
Note | Cisco Prime DCNM Release 7.2(x) does not support Oracle 12c pluggable database version installation. |
Oracle 12c RAC (nonpluggable installation)
Note | From Cisco Prime DCNM Release 7.2(x), the 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. We recommend that you use Oracle SE or Enterprise edition instead of Oracle XE due to table space limitations. |
Note | Customers are responsible for all the support associated with the Oracle database, including maintenance, troubleshooting, and recovery. We recommend that customers perform regular database backups, either daily or weekly, to ensure that all the data is preserved. |
Cisco Prime DCNM, Release 7.2(x), supports the running of the Cisco Prime DCNM server on the following hypervisors:

If you install Cisco DCNM in a virtual machine, you must reserve resources equal to the server resource requirements to ensure a baseline with the physical machines.
Some Cisco Prime DCNM features require a license. Before using the licensed features, you must install the Cisco Prime DCNM license.
Note | Ensure that you set the correct time zone value on the client system's clock, for example, UTC. Otherwise, Cisco Prime DCNM cannot manage the switch properly. |

Network Time Protocol
General Guidelines
Do not deploy Cisco Prime DCNM when network latency is more then 50 ms from the switch management subnet to the Cisco Prime DCNM server and Cisco Prime DCNM database.
Deploy Cisco Prime DCNM on high-performance tier storage (2 to 4 ms response time).
Create users with the same password digest and encryption algorithm in the device (for example, Digest, MD5) and encryption algorithm (for example, DES). Cisco Prime DCNM will not authenticate the devices with different digest and encryption passwords.
Deploy Cisco Prime DCNM-SAN in a federation configuration when either of the following conditions is met:
Windows Operating System
Virtual Machines
