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.

We recommend that you deploy Cisco UCS Central on a standalone rack server 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 TCP ports must be open between Cisco UCS Manager and a registered Cisco UCS domain for the firmware management and backup functionality to work correctly:
The following table describes the minimum requirements for the standalone rack server on which you deploy Cisco UCS Central.
Requirement | ESX Minimum Requirement | Hyper-V Minimum Requirement |
---|---|---|
Disk space |
60 GB |
60 GB |
RAM |
4 GB |
4 GB |
VCPU cores |
1 core |
2 cores |
Disk read speed |
> 75 MBps >125 MBps is the recommended speed. |
> 75 MBps >125 MBps is the recommended speed. |
Note |
Performance of Cisco UCS Central is not guaranteed if you deploy it on a server that does not meet the minimum disk read speed requirement. |
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 |

When you deploy Cisco UCS Central, you need to provide the following information:
A password is required for each locally authenticated user account. A user with admin, aaa, or domain-group-management privileges can configure Cisco UCS Central to perform a password strength check on user passwords. If the password strength check is enabled, each user must have a strong password.
Cisco recommends that each user have a strong password. If you enable the password strength check for locally authenticated users, Cisco UCS Central rejects any password that does not meet the following requirements:
