==Welcome==

Welcome to the OCP '''Immersion Cooling''' Sub-project to the Cooling Environments Project.

This Project is open to the public and we welcome all those who would like to be involved.

Disclaimer: Please do not submit any confidential information to the Project Community. All presentation materials, proposals, meeting minutes and/or supporting documents are published by OCP and are open to the public in accordance to OCP's Bylaws and IP Policy.

''For Cooling Envitonment Project leadership, please refer to the Cooling Environments Wiki page''
:- [https://www.opencompute.org/wiki/Cooling_Environments Cooling Environments Wiki]

''Workstream leadership''
:There are various workstreams within the immersion project with their own respective workstream leaderships. An overview can be found under [https://www.opencompute.org/wiki/Cooling_Environments/Immersion#Immersion_Project_and_Workstreams Immersion Project and Workstreams]
:See the orgchart on the right side (click to enlarge) for the full overview of all workstreams and responsibilities within the immersion project.

===Activities===
The Immersion sub-project enables community driven activities focused on facilitating OCP and industry progression of immersion cooling. Within the Cooling Environments (CE) group, this project also facilitates harmonization among other sub-projects and various other industry platforms.

===Related documentation===
Additions or changes to put on the agenda of different focus groups can be included in the "Suggested Changes" document.

==Immersion Requirements Qualification==
The Immersion Requirements sub-project is responsible for the generation and qualification of requirements for immersion solutions. The requirements are aimed at ensuring accurate and factual technology positioning and weeding out marketing claims vs solid engineering. Vendors need to qualify against the requirements which are outlined in the [https://www.opencompute.org/documents/ocp-acs-immersion-requirements-rev-2-v1-00-pdf Immersion Requirements document] to gain access to a variety of OCP domains, including marketplace or SPEC recognition. Some examples are as follows:
:- OCP immersion spec submission
:- OCP Logo accreditation for immersion solutions (accepted/inspired)
:- OCP solution branding
:- OCP Marketplace positioning
:- OCP Solution building

The qualification process is as follows:
:1- A qualification request with a filled-out [https://drive.google.com/u/0/uc?id=1-XnBAa8uDcvrPQkoEaxnBGHFysUln52z&export=download checklist] shall be sent to the Immersion Community project leads.
:2- The Project leads will assess the submission and checklist and when accepted, schedule a 20-minute presentation for the submitter in the next available community call time slot.
::a- The presentation shall be made available to the project leads at the latest 1 week before the scheduled community call.
::b- The presentation shall explain why and how the submitted solution qualifies against this Immersion Requirements document.
:3- A 60-minute interactive review will be scheduled by a community committee:
::a- The committee is overseen by one of the immersion project leads.
::b- The committee will consist of the Immersion Requirements authors which are invited by the project leads.
::c- All materials (checklist, community presentation, community questions and other collateral) are shared with the reviewers at least 1 week before the review meeting.
:::i- There will be 1 week to review materials, request additional feedback and ask follow-up questions after the review session;
:::ii- There will be 1 additional week to allow for all votes to be cast;
:::iii The committee will approve, decline or provide feedback to resolve before approval, based on the Immersion Requirements.
:4- The community committee is formed as follows:
::a- All authors of the Immersion Requirements document are invited to be panelists;
::b- One of the immersion project leads oversees the qualification process and panel;
::c- Each company represented in the panel counts as 1 vote (excluding the qualifying company);
::d- A quorum is achieved with a minimum of 5 votes present in the panel.
