Subject: [ocp-acf] Reviewing support for "Immersion Requirements rev2"

 

Dear members of the OCP ACS and DCF groups,

 

I would like to let you know that the new Immersion Requirements Rev2 document has been prepared for broader community review. Since these requirements also relate to facilities and operators, I wish to request review support of both our communities.

 

Document link:

https://docs.google.com/document/d/1VN0yd5bySgiIxwWTpWUcOejionp6cz5D/edit#heading=h.haapch

 

Review scope:

We welcome your support by reviewing the overall content, scope and quality of information.

Please do NOT comment on formatting, grammar or spelling. This will be too difficult to keep track of at this stage.

Please exclude the appendices, as these will be built and completed in the following stages of the document.

 

Special request to ACF group:

I kindly request your attention to chapter 6, “Datacenter Interface Requirements”, as this requires harmonisation with on-going activities.

 

On-going work

The document is still work in progress, so keep in mind that the following is still on-going:

  • Specific content related to fluid references is still being discussed and may be subject to change;
  • All requirements still need to be rewritten and more specifically categorised;
  • Intro and appendices will be finalised at the near-completion stage.

 

Feedback:

Please provide your feedback by means of comments in the document.

Please suggest change proposals or content additions in the following document:

Dear Rolf Brink, Don Mitchell and coolant manufacturers,

 

I want to ask you one question on how to maintain the quality and performance of coolant for a long time. If you already have an answer, I would be very grateful if you could guide me.

In the case of liquid cooling, it is very important to prevent the quality of the coolant from external moisture or contamination. When you talk about the 10-15 year lifespan you are talking about, please give your opinion on how to maintain the quality of coolant.

 

Stay safe and wish all nice summer vacation.

 

Thanks,

JB KIM

Re: [OCP-ACS-Immersion-Cooling] [ocp-acf] Reviewing support for "Immersion Requirements rev2"

 

Hi Raul,
let's keep a conversation free from advertising, brand names - you are doing a great job and with that scarcity of immersion cooling vendors' anybody knows Submer brand already. 

Secondly, I believe JB KIM is not asking "how to prevent water-glycol" from moisture ;) and all understand that immersion systems use hydro carbonated fluids (dielectric oils) and not water-glycol for actual immersion :). 

Anyway JB KIM with the closed immersion enclosures and usual immersion system temperature range + steel tanks -  it is unlikely to get moisture content in the dielectric oil, even in mobile applications without good ambient temp control. Most dielectric fluids are hydrophobic also, so water content is isolated to some extent.
Since insulating oils are used in transformers mostly, there is a lot of expertise in Transformer / insulating oil long-term maintenance. Companies use different oil purification systems from simple multi-filter carts to more sophisticated purification/dehydration / "drying" plants and mobile purifiers/machines. 
Even contaminated dielectric oil, after treatment with vacuum, the multi-stage purifier, will have extremely low water content and will be clean from all impurities. So basically it's about observation, testing of water content (cheap to do on-site or in a remote lab) and if needed - purchase of own filter or ordering quick filtering service from a company dealing with insulation oils. Simple as that, and the immersion system will run for multiple years without any dielectric fluid change.

Hi Kim,

Raúl Álvarez, Lead Solution architect at Submer. We are an immersion cooling vendor who engineers and produces it's own Technological (Systems and accessories) and chemical (liquid) stack.

Those lifespans are highly dependant on the chemistry of the liquids. Our SmartCoolant liquid, is hydrocarbon-based, which by itself has a minimal amount of moisture, and not water-glycol based. Moreover, we constantly monitor the quality of the fluid with on-board sensors.

Hope I've helped to move you in the right direction.

Dear Rolf Brink, Don Mitchell and coolant manufacturers,

I want to ask you one question on how to maintain the quality and performance of coolant for a long time. If you already have an answer, I would be very grateful if you could guide me.

In the case of liquid cooling, it is very important to prevent the quality of the coolant from external moisture or contamination. When you talk about the 10-15 year lifespan you are talking about, please give your opinion on how to maintain the quality of coolant.

Stay safe and wish all nice summer vacation.

Dear members of the OCP ACS and DCF groups,

 

I would like to let you know that the new Immersion Requirements Rev2 document has been prepared for broader community review. Since these requirements also relate to facilities and operators, I wish to request review support of both our communities.

 

Document link:

https://docs.google.com/document/d/1VN0yd5bySgiIxwWTpWUcOejionp6cz5D/edit#heading=h.haapch

 

Review scope:

We welcome your support by reviewing the overall content, scope and quality of information.

Please do NOT comment on formatting, grammar or spelling. This will be too difficult to keep track of at this stage.

Please exclude the appendices, as these will be built and completed in the following stages of the document.

 

Special request to ACF group:

I kindly request your attention to chapter 6, “Datacenter Interface Requirements”, as this requires harmonisation with on-going activities.

 

On-going work

The document is still work in progress, so keep in mind that the following is still on-going:

  • Specific content related to fluid references is still being discussed and may be subject to change;
  • All requirements still need to be rewritten and more specifically categorised;
  • Intro and appendices will be finalised at the near-completion stage.

 

Feedback:

Should ACS vendors be expected to provide BIM LoD 350 Content of their products?

Don Mitchell
 

In the Advanced Cooling – Facilities (ACF) subproject today, presentation was provided on the impact of BIM in data center construction and adaptation.

If you did not see the discussion, recommend watching the replay, particularly after the 6 minute point. https://www.youtube.com/watch?v=aWFs1wCsxM0

 

One of the “Asks” from ACF is that ACS provides modeling that can be designed as a BIM projec that can be accurately fabricated offsite, delivered and installed with precision, speed, accuracy (within 1/16th inch)

 

Key questions–

  • Does providing BIM LoD model present any challenges to vendors (is the cost too high, is there an IP concern)?
  • Do you see the value of BIM LoD content (reduces design & fabrication cost and time)

 

Today, when engineers design in BIM they use product models – if high level content is not available from the vendor, the engineer spends time and money to  create product models to design the solution

 

Contractors and fabricators often take the engineers design and redo to make sure it has the accuracy required to fabricate (or they just custom construct).  Once again, time and cost is added to the project

 

If high level BIM content is available from vendors, the time and cost to go from concept to fabrication (offsite) to installation drops significantly.

While BIM has been around for decades, the employment of BIM LoD 400 has only been around a couple years, and it is transforming the industry.

 

Regardless of whether ACF adds this as a recommendation or a requirement, the industry will likely drive the issue in the coming years.

Would like to position OCP to be leaders on this topic.  Let me know your insights

 

 

Kind Regards

Use of BIM to harmonize Advanced Cooling Solutions with Data Center Facilities - request for revit models from vendors

Don Mitchell
 

Action request – Revit models of ACS products

 

12/8 Advanced Cooling – Facilities (ACF) subproject is hosting a discussion on use of BIM to enable addition of ACS solutions into data centers.

 

Please advise if any ACS vendors provide modeling of their solutions. 

Would also value insights on barriers, benefits of sharing this information

 

For the purposes of next weeks discussion, we are primarily seeking for next week’s discussion/demonstration:

  • Correct geometry for the products, including dimensional accuracy

 

Additional details for optimal integration would include items listed below

 

Anyone interested in seeing how BIM solutions can greatly simplify adding ACS to data centers feel free to attend next Tuesday at 1100 ET/1600 GMT

BIM Documentation requirements from ACS Vendors:

  1. Correct geometry for the products, including dimensional accuracy
  2. Revit piping and electrical connectors (at a minimum)
    1. Correct system specification (ie hydronic supply and return, NOT chilled water)

                                                               i.      Ideally, they would program in the dP vs flow rate table into the pressure drop parameter, but that’s not a requirement IMO.

    1. Correct voltage, with correct load classification and kW parameters
    2. Connection locations to be dimensionally accurate

                                                               i.      If multiple connection locations are available, include all available in the RFA

    1. CDUs should have the TCS pumps included (ie power connection and power characteristics
  1. Proper hosting which, IMO, should be hosting to the floor

 

Once the dimensionally accurate geometry is produced, the remainder of the above information can be added to the RFA in a few hours.

OpenComputeProject - specifying Offsite/Prefab Precision to address the challenge of cooling adaptability [EXT]

Don Mitchell
 

On next week’s OCP call, we are planning on hosting a discussion on use of Revit in future planning of addition of liquids to data centers. 

Would value response from vendors that have products accurately modeled in Revit content libraries

 

Presentation Goals:

  • ease, speed, accuracy of transforming a reference design into BOM (bill of materials), ready to ship
  • Adding content from libraries.  Demonstrate how easy it is to include, integrate Revit library content into a dwg
  • onsite assembly with minimal (No?) jobsite modification/engineering. 
  • Is this possible, is it happening now – would value insights from any vendors that are already providing this service for customers, either directly or via partnership with MEPs

 

Are you available to support this Tuesday 8 December at 1100 ET

 

Kind Regards

Hi Don,

 

I have to drop early from the call I’m afraid, I’m getting pulled into something unexpected. Really interesting conversation and presentation.

 

Were you planning on discuss the topic of BIM? I’d be happy to join a future call and provide a presentation on our design capabilities.

 

Thanks, Steve

Steve – appreciate the insights and discussion. 

 

As mentioned, I will be hosting an OCP call 1 December-  “Using Perfect prefab to add liquid cooled IT solutions”

 

Would value your attendance, and possibly Amy as well due to her understanding of data centers

Will add you both to the call invite for 1 December. 

Also inviting other MEPs, vendors and owners with familiarity on capability of Revit

 

The vision is that with proper use of BIM/VDC technologies and facility discipline, adding liquid cooled IT could be a pre planned evolution with minimum/no jobsite customization.

A key question is whether to recommend/require this approach?.

 

Data Centers are evolving to add liquids to improve performance and efficiency

Thanks for leading the change

Case 1 – Attaching to existing loop

  • Planning for Pipe Connections –
    • Size, Flow, KW
    • Pipe Path
      • Prefab vs jobsite craftwork
      • “Last Meter” - Loop to ITE connection – topic for 11/24
  • CDU/HX Vs Direct Connection (discussions 11/17)
    • Direct connection, with ACS vendor providing CDU/HX functions as needed
      • Examples –
        • Asperitas uses internal HX, no need for CDU
        • GRC provides CDU for group of Immersion Tanks
        • CoolIT provides CDU for row of coldplate
        • RearDoor HX typically connect direct to FWS
  • Risk Considerations,  Reliability Considerations
    • Myth Vs Real Risk – Data Center pipe solutions have demonstrated decades of reliable performance.  As the data center design migrates to an environment where pipes are run above floor, risk concern can be minimized by following basic guidelines
      • FMEA – Failure Mode & Effects Analysis – process recommended for evaluation of protection from leaks, condensation.  Examples –
        • Condensation Protection - Historically, liquid cooling water supplies were at risk of dewpoint/condensation, and drip trays were often recommended.  Many data centers and liquid cooled solutions today operate above dewpoint.  FMEA analysis should be considered for Cost and design impact of condensation collection where there is no risk of condensation, need for drip trays, condensation
        • Maintenance requirements, location and protection – valves and components that anticipate maintenance should be located in minimal risk areas or protected during periods of maintenance
      • MTBF/Warranty/Inspection
        • Pipe integrity is exceptional when properly installed, inspected and maintained. Key potential risks
          • Weld Integrity – MTBF data is not available for welds.  Inspection process for welds per ASME B31.3 recommended
          • Grooved Coupling Solutions – Mission Critical coupling solutions when properly installed and inspected have demonstrated and designed performance that exceeds building lifespan (30+ years).  MTBF > 150M hours and manufacturer’s warranty of 20+ years are recommended
            • Key components of Mission Critical grade components
              • Traceable quality control to date, location of manufacture
              • Certified installation and inspection process that delivers required MTBF and warranty.
          • Flanges [Alignment, Torque Requirement – more discussion needed]
          • Flex Connectors, movement devices  [Alignment, Torque Requirement, Maintenance, lifespan – more discussion needed]
          •  
    • Condensation risk 
      • Operation above dewpoint is preferred when possible [more discussion needed}
      • Condensation protection/Detection/Collection – [more discussion needed}
    • Concurrent Maintainability – Aligning with The Uptime Institute Tier Guidance
      • Tier 4 looks at reliability through failure, i.e. would data center function continue if pipe failed. 
      • Tier 3 focus
        • concurrent maintainability – can data center operations continue through planned maintenance.
          • Internal redundancy of the ITE is not a “tier issue”.  For example, cooling supply to the immersion tank, doorHX, coldplate is a Tier III consideration.  Distribution of liquid and components inside the ITE is not an issue. 
            • Impact of opening a doorHX could be an issue if it affects adjacent ITE
          • Redundancy of ITE might be a consideration.  i.e.  multiple HPC racks providing identical function set up in N+1 configuration
        • Leak, condensate detection, collection requirements generally recommended, but would vary with owner and risk evaluation.
        •

Steve – greatly appreciate the interest.  Not sure your familiarity with OpenComputeProject (founded in 2010? By FB) but they have expanded their focus to include addition of liquid cooled IT into data centers.  The Advanced Cooling – Facilities (ACF) subproject of OpenComputeProject is developing guidance, reference designs, and case studies around deployment of liquid cooled IT in data centers.

 

Question was raised on whether Offsite manufacturing and precision prefab could/should be developed as a standard as part of the lifecycle vision of a data center to add liquids

Looking for insights that would support that premise. 

 

Let me know if you have time to talk Monday, my schedule is very busy, but flexible.

 

We are hosting weekly calls, will add you to invite.  Meeting notes from 27 Oct and Agenda for 3 Nov attached, meetings scheduled 1100 ET/1600GMT Tuesdays.

 

3 Nov Focus –– Considerations to maximize reliability, cost effectiveness:

  • FMEA (Failure Mode & Effects Analysis) -  Method to evaluate level of protection, redundancy vs risk    (past discussions have looked at using specification of  MTBF data, Manufacturer’s warranty, Offsite Prefab precision as means of controlling risk)
  • “Concurrent Maintainability”.  Adding Liquid cooled IT to air cooled data centers can impact the “concurrent maintainability level of the data center as a whole.  When is that an issue?

 

Meeting focus 27 Oct –Reference Design Considerations, CDU requirements

(Notes attached)

 

Would greatly value your insights and participation. 

Please advise if you object to being added to the mailing/invite list.

Hi Don,

 

Amy (copied) forwarded your email, my apologies for the delay in responding!

 

My name is Steve Butler and I’m an Industry Strategist in our Building Design division at Autodesk, responsible for our MEP business line. In addition, I own our cross-disciple DfMA strategy from a ‘design‘ perspective. A relatively new initiative for Autodesk. Nice to meet you, albeit virtually.

 

Your OpenComputeProject sounds very interesting. Would you be free for a quick call next week to discuss this in more detail? If you can send me your availability, I’ll try to adjust my schedule accordingly. I’ve worked with Victaulic for a number of years as you are MEP Strategic Industry Partners.

 

Kind regards,

Steve

Amy  –  Hope all is well.  Seeking advice on setting up guidance around offsite/prefab quality and LoD

 

Do you currently see any specifications that reference LoD and/or component MTBF?

Would value your insights on how to specify Offsite/prefab to address challenges in adaptability of liquid distribution in data centers

 

I was recently invited to lead a team at OpenComputeProject on Advanced Cooling – Facilities (ACF)

Mission is to develop best practices, collaboration documents and common guidelines facilitating the integration/addition of Liquid cooling into data center facilities.

 

In addition to developing reference designs and layout recommendations, looking at introducing guidance to ensure reliability, scalability and adaptability.

  • Deployment of liquid distribution solutions in operating data center IT spaces creates need for new/additional guidance to support adaptability with reliability
  •  Advances in construction technologies and delivery methods can be aligned with reliability science tools to provide “life of the data center” solution expectations

 

Have bi-weekly discussions on spec development, tomorrows topics include:

Discussion Points  – Considerations to maximize reliability and cost effectiveness:

  • Leakage Protection/Detection Strategy - Where/when should leakage protection and detection be required, recommended? 
  • MTBF data – can it be applied / required for pipe solution reliability?
  • Manufacturer’s warranty, recommended solution life – how can this be applied to optimize design reliability
  • Is Perfect Prefab a solution?- How to maximize/specify use of offsite manufacturing “precision prefab” processes (BIM LoD 350, 400) to minimize risk

 

Please advise if you object to being added to the mailing/invite list.

 

Future Meeting Schedule:

  • Meeting  10/27 :  Reference Design Development
  • Meeting 11/3:  OCP Guidelines for FWS/CWS Piping, Valves, & Specialties

How is ACS being deployed in data centers today?

Don Mitchell
 

The purpose of this message is to collect input from ACS vendors (DoorHX, cold plate, immersion) on current methodology and issues associated with connecting liquid cooled solutions to medium-large scale data centers using slab floor designs.  Please respond with any insights (please advise if you prefer anonymity).

 

  • In a 2MW-10MW slab floor data center, what source of cooling liquid would you connect to
    • Direct to existing loop, using cooling loop liquids, temperatures, dP
    • Direct to existing loop, using a CDU/HX to align temperatures, pressures and dP  (including CDUs integrated with ITE solutions)
    • Independent loop to external HX
  • In a slab floor data center, how would you connect to the liquid distribution loop  (select or comment on all that apply)
    • flexible drop (hose) vs fixed pipe
    • balancing valve vs no balancing valve
    • Thread connection, flange connection, grooved coupling solution, braised/fused connection
      • Does the current connect solution meet your needs

 

The Advanced Cooling – Facilities (ACF) subproject of OpenComputeProject continues  - developing guidance, reference designs, and case studies around deployment of liquid cooled IT in data centers.

A “Map” of the ACF vision is attached at the bottom of this message.  We have been covering a lot of foundational discussions in preparation for delivery of reference designs and guidance

 

Discussions on Tuesday, 17 November will include TheUptimeInstitute addressing Tier rating impacts as well as continued discussions on use of CDUs and HX

Future discussions will include

  • Connection types – what is the best method to connect ACS to FWS
  • Prefab Perfection – inviting design leaders and members of BIM solutions to discuss practicality of defining “perfect prefab” – offsite constructed, prefabd solutions that require no jobsite adaptationl

 

Would greatly value your insights and participation. 

Please advise if you object to being added to the mailing/invite list.

 

OpenComputeProject Tech Week was very successful, a lot of key insightsl.  Sessions are recorded.  Go back and listen if you were not able to attend

Re: Heat Reuse designs, metrics, market - Creation of workstream [EXT]

Archibald, Matthew
 

On the back of what Francois stated, the CDU should be regulating the fluid flow and temperature on both the primary (FWS) and secondary (TCS) loops.

 

On the primary side, the flow can be controlled to get a more consistent primary return temperature while still maintaining tight operating conditions for the secondary loop.  One of the easiest ways to accomplish this is with dynamic flow on the primary, and CDUs with lower and constant approach temperature support across the operating range.

Hi all,

 

I am very interested in that topic.

Regarding adoption, we may avoid talking about direct heat reuse, as the water outlet temperature is not always stable. To avoid facility management to pushback, we might advise to use the same strategy as the Swedish public hot water loop and install a heat pump between the DC water loop and the facility hot water loop.

 

The heat pump will have a COP of 6 to 8 and will act as a regulator of the facility water temp. Anytime I saw colleagues advocating for direct heat reuse, we saw pushback from facility management.

 

Also, we should not advocate on “running dummy code” to heat the system (I really saw people using that…) as the COP of a CPU is 1… regulation by the CPU load is not a sustainable strategy.

 

Last but not least, the facility management investment is a 10 to 25y CAPEX, while IT is a 3 to 7y. the heat pump will ensure the hot water loop and the DC loop will remain compatible.

If you look at Facility (DC) projections on CPU density, you will see that they  never ever planned 200W CPU. So, whoever can forecast rack density and temperatures 20y ahead is a genius.

My 2 (or maybe 3) cts.

 

François.

Here in hot & humid Singapore/Tropics, we are working to use low grade waste heat (~40°C) from DC for regeneration of desiccant dehumidification which can be coupled with IEC for DC cooling. Will be most glad to be part of this work stream.

Heat reuse is gaining momentum in regions that are cool, have district heating infrastructure, motivated by sustainability

Northern EMEA has all three.  China is also advancing in these areas,

 

USA generally is warmer or does not have district heating type applications near data centers

Agricultural applications are also common, but rather superficial in many ways (growing bananas in Norway is not really a promotion of sustainability).

 

Increasing the quality of heat (higher temperature liquid) broadens application options beyond cold climate agriculture and district heating

30 C waste heat is almost useless outside of cold climates, but 60C waste heat liquid has many applications

Input from Intel is needed to validate whether 60C waste heat makes sense

 

Cloud&Heat is an example of edge data centers providing utility that can be applied almost anywhere https://www.cloudandheat.com

Key goal is promotion of vision to drive development of solutions that are cost effective and efficient.

 

Open to correction and insights

Message goal –

·       Coordination of organizations in OCP and external to OCP seeking to address sustainability metrics

·       Coordination of efforts in OCP and external to OCP seeking to advance energy reuse metrics

Action Request

·         creation of workstream or wiki page/collaboration site to update with progress in these areas

·         Notification of organizations involved in sustainability metric development applicable to data centers

 

Sustainability is rapidly becoming the top issue for the data center industry, many are working on development of better methods of measuring sustainability.

Energy Reuse is a key factor in data center sustainability.  Enablement of Energy Reuse is a key potential benefit of increased use of liquids in data center operation.

 

Advancement of Energy Reuse applications requires market awareness, data center design, metric evolution

·         Market awareness – happening in EMEA, APAC now, creeping slowly into North America

·         Data Center Design – ACF will be progressing in this area, most likely in 2021

·         Metric evolution – Metrics are essential in acceleration of awareness, incentives and mandates.  PUE is the most widely known metric of data center efficiency, but is well known to lack alignment with liquid cooling and energy reuse.  TheGreenGrid is seeking to evolve PUE, but no longer has legal right to make changes without permission
