Inquiry Regarding CPU Configuration on PowerEdge R440 Servers

Hello everyone,

I am reaching out to seek guidance on a matter related to our Dell PowerEdge R440 servers.

Recently, we received communication from VMware regarding a potential increase in subscription prices. In an effort to manage costs, we are exploring options to optimize our hardware configuration. Specifically, we are considering reducing the number of active CPUs per server.

I am inquiring to understand if there is a supported method or feature within the PowerEdge R440 servers, accessible through iDRAC9 or other firmware settings, that would allow us to disable or deactivate one CPU without the need for physical removal.

Our objective is to explore potential cost-saving measures without compromising the overall performance and stability of our server infrastructure.

If direct CPU deactivation is not possible through iDRAC9 or firmware settings, we would appreciate any guidance or recommendations you can provide on achieving this goal while ensuring compliance with system specifications and warranty terms.

Additionally, if there are BIOS/UEFI configurations or other features that could assist in temporarily deactivating a CPU, we would like to explore those options.

We understand the importance of maintaining system integrity, and we appreciate your expertise in guiding us through this process. If further details or system information are required to address our inquiry, please let us know, and we will provide the necessary information promptly.

Thank you for your attention to this matter. We look forward to your guidance and assistance in optimizing our server configuration.

I am not certain of a way to disable the CPU as a whole, while it is still installed. Now I do know that you can disable Cores for each CPU as seen on the page here, but I am not sure if that is what you are looking for. 


 Let me know if this helps.

@DELL-Chris H​ Many thanks, it works for me . 

Now I can reduce the amount of cores per socket.
