Enchance the cooling algorithm to work for chassis

rlhui commented 1 year ago

Hi @arlakshm , wondering what's the priority of this one? And background of this? Thanks.

kenneth-arista commented 1 year ago

Basic cooling algo has been added via https://github.com/aristanetworks/sonic/commit/302c32be14c1dc2bb0bb5a01f8ff30dbfaab8422. More enhancements will be discussed with the community.

@arlakshm there's been some development in this area. I'm refactoring our cooling algorithm so it can gather sensor information from CHASSIS_STATE_DB. It should be ready in the coming weeks on master and 202305.

Changes related to the cooling algorithm have merged in master and 202305. Here is the PR for 202305 https://github.com/sonic-net/sonic-buildimage/pull/16702 The only thing that cannot be taken into account is the linecard transceivers temperatures since it's not available to the supervisor. Ideally these should be populated into CHASSIS_STATE_DB as well. Marking this issue as solved.
