DCNM_root_directory/java/jdk11

Server Requirements

Cisco DCNM Release 11.5(2), supports the Cisco DCNM server on these 64-bit operating systems:

• SAN Deployments:

  • Microsoft Windows 2016

  • Microsoft Windows 2012 R2 update 2919355

  • Red Hat Enterprise Linux Release 7.8, 8.1, and 8.2

  • Open Virtual Appliance (OVA) with an integrated CentOS Linux release 7.8

  • ISO Virtual Appliance (ISO) with an integrated CentOS Linux release 7.8

• LAN Fabric Deployments:

  • Open Virtual Appliance (OVA) with an integrated CentOS Linux release 7.8

  • ISO Virtual Appliance (ISO) with an integrated CentOS Linux release 7.8

Database Requirements

Cisco DCNM Release 11.5(2) 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	Oracle 12c pluggable database version installation is not supported.

• Oracle 12c RAC (nonpluggable installation)

• PostgreSQL 10.15 - For OVA/ISO deployments

• PostgreSQL 10.15 - For Linux/OVA/ISO deployments

• PostgreSQL 10.15 - For Windows deployments

Note

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.

Note	The ISO and OVA installations support only the embedded PostgreSQL database.

Server Resource (CPU/Memory) Requirements

Note	If you install Cisco DCNM on a virtual machine, you must reserve resources equal to the server resource requirements to ensure a baseline with the physical machines.

If the existing Elasticsearch database is more than 250GB, Cisco DCNM Server requires more than 500GB HDD space to complete reindexing.

Ensure that there is enough disk space to the root partition or mount another disk where the /tmp directory can be mounted during the installation or upgrade.

Allocate sufficient disk space to the root partition to complete DCNM installation and for stable continuous operation of the DCNM applications. Refer to the applications’ User guides for disk space requirements. You can mount another disk where the /tmp directory can be mounted during the installation or upgrade. You can also add additional disk space and the disk file system using appmgr system scan-disks-and-extend-fs command.

Note

From Release 11.3(1), Cisco DCNM Windows deployments does not support the SAN Insights feature. Cisco SAN Insights feature is only supported with the Huge deployment. Every federation deployment consists of three large configuration nodes. From Cisco DCNM Release 11.2(1), synchronize the Federation nodes from the Primary node only.

Client Hardware Requirements

Cisco DCNM SAN desktop client and Cisco Device Manager support Microsoft Windows 10, Microsoft Windows 2012, Microsoft Windows 2016, and Red Hat Linux. The following table lists the minimum hardware requirements for these client systems.

If you install Cisco DCNM on a virtual machine, reserve resources equal to the server resource requirements to ensure a baseline with the physical machines.

Some Cisco DCNM features require a license. Before using the licensed features, install a Cisco DCNM license for each Nexus-managed or MDS-managed platform.
