If you are installing Cisco UCS Central in a standalone mode, make sure you have the following system requirements.
We recommend that you deploy Cisco UCS Central on a VMware or Hyper-V hypervisor running on standalone rack server(s) that is not managed by Cisco UCS Manager or integrated into a Cisco UCS domain. The server must have a high-speed data store, preferably one provisioned from a high-speed storage array.
The following ports must be open between Cisco UCS Central and a registered Cisco UCS domain to enable management communication between Cisco UCS Central and Cisco UCS domain:

If the disk read speed on the server is lower than the required minimum during the deployment of Cisco UCS Central, the installer displays a warning message but you can complete the deployment. However, if the disk read speed is lower than the required minimum during operation, Cisco UCS Central raises a fault, as shown in the following table, depending upon how low the disk read speed is:
Disk Read Speed on Server | Fault Level |
---|---|
<75 MBps |
Critical fault |
75 to 100 MBps |
Major fault |
100 to 125 MBps |
Minor fault |
>125 MBps |
N/A |
The following are the supported database servers for statistics collection:
When the statistics data is stored in external database server, Consider the following as a reference data for disk space requirements on the database server:
The minimum memory required for client system is 4 GB. However if you have 40 or more registered Cisco UCS Domains, it is recommended to have at least 8 GB memory on the client system.
If you want to enable high availability and install Cisco UCS Central in cluster mode, you must have all the requirements specified for standalone installation, and have the following Shared Storage:
