Cisco UCS Server BIOS Tokens in Intersight Managed Mode

Introduction to Intersight Managed Mode Server BIOS Tokens

Intersight Managed Mode provides two methods for making global modifications to the BIOS settings on servers in Cisco UCS domain. You can create one or more BIOS policies that include a specific grouping of BIOS settings that match the needs of a server or set of servers, or you can use the Cisco provided predefined BIOS policy settings which are optimized for particular server platforms and use cases.

Both the BIOS policy and the default BIOS settings for a server platform enables you to fine tune the BIOS settings for a server managed by IMM.

Depending on the specific workload requirements of a data center such as CPU-intensive, I/O-intensive, or energy-efficient operations and so on, Cisco provides optimized, ready-to-use BIOS token configurations. These configurations are designed to streamline policy deployment and enhance system performance by aligning BIOS settings with workload demands. Additionally, custom policies can be created to meet unique requirements.

Cisco Intersight Managed Mode supports the following M5, M6, M7, and M8 servers:

Cisco UCS C220 M8, Cisco UCS C240 M8, Cisco UCS X210c M8 Compute Node

Note

This platform is supported from 4.3(6a) onwards.

Cisco UCS C225 M8 and Cisco UCS X215c M8 Compute Node

Note

This platform is supported from 4.3(5a) onwards.

Cisco UCS C245 M8
Cisco UCS X210c M7 Compute Node
Cisco UCS X410c M7 Compute Node
Cisco UCS X210c M6 Compute Node
Cisco UCS C220 M7
Cisco UCS C240 M7
Cisco UCS C220 M6
Cisco UCS C225 M6
Cisco UCS C240 M6
Cisco UCS C245 M6
Cisco UCS C220 M5
Cisco UCS C240 M5
Cisco UCS C480 M5
Cisco UCS B200 M6
Cisco UCS B200 M5
Cisco UCS B480 M5

Note

The Version column in the table denotes the minimum firmware version where the BIOS token is supported and its consecutive version support.

Note

For tokens having long value description, the Values column can be seen blank. In this case, you can scroll down the column to see their values.

Note

All tokens also include a 'Platform default' option. The Platform default is identified by the setting in bold font. The BIOS uses the value for this attribute contained in the BIOS defaults for the server type and vendor.

What's New

Note

This document includes BIOS token information starting from 4.3(3a) and continue to cover all subsequent versions. It does not cover any versions prior to 4.3(3a).
