00:22:07 Greg Stover/VERTIV: Greetings from Laguna Hills my OCP Ecosystem friends :-) 00:23:16 Archna Haylock: hi Greg!! 00:23:20 Kate Hendle: Welcome to Day 1 of the Cooling Environments Tech Talk! Please put any questions for the speakers here in the chat and keep yourself on mute if you are not speaking. 00:23:20 John Menoche: Welcome Greg! Glad to see you 00:24:15 Archna Haylock: this call is recorded. Call recordings and chat transcripts for this and other Tech Talks can be found here: https://www.opencompute.org/events/past-events 00:24:43 Archna Haylock: Cooling Environments Project - https://www.opencompute.org/projects/cooling-environments 00:25:19 Archna Haylock: please subscribe to the mailing list to keep up with all the activities. 00:34:52 Joshua Au: Just to sure this is a rear door exchange 00:35:17 Kenneth Kiernan: correct 00:35:53 Henry Amistadi: Is there a link to this briefing? 00:41:42 Gaby Mindreci m-i2i.com: Hello to all! 00:43:05 Archna Haylock: hi Gaby !!! 00:43:06 Jaime Comella (C&H): 👋🏻 00:50:20 John Gross, JMGE: Hey Cosimo, hold my beer :-) 00:51:45 Archna Haylock: 😅 00:52:09 Cosimo Pecchioli: 😄 00:52:42 Archna Haylock: @John Gross - Is it a cold “American” beer and are you re-using the heat? 00:54:03 John Gross, JMGE: I was thinking a nice temperate Guiness, you know, for energy efficiency. 00:54:49 Joshua Au: Would and should the reuse of heat change how PUE is calculated 00:55:09 Jaime Comella (C&H): happy to discuss this afterwards 00:55:10 Archna Haylock: Heat Reuse Sub-Project - https://www.opencompute.org/projects/heat-reuse-incubation 00:55:18 Jaime Comella (C&H): 👍🏻 00:55:47 John Gross, JMGE: @Joshua Au, PUE struggles to deal with almost all liquid cooling solutions due to the removal of the heat sink and power supply cooling fans, and the resultant decrease in the denominator of the PUE calculation. 00:56:01 John Gross, JMGE: Heat reuse adds yet another challenge. 00:58:19 Jaime Comella (C&H): Guiness for breakfast is always good 00:59:18 Joshua Au: PUE simply can’t and I think as a community we need to reconcile the two 01:02:20 Joshua Au: The performance indicator alludes to the trade offs involved in PUE and the different risk appetites of different operators but the point was lost on the community of operators 01:04:20 Kenneth Kiernan: Very important discussion, thanks for helping to explain the background of PUE, @Don Mitchell and team! 01:10:47 Joshua Au: It’s hard to go so far as ISO14000 and see it from a lifecycle perspective and the Barrier to entry is the almost impossible effort taken to trace all the parameters 01:12:43 Kenneth Kiernan: Interesting.. PUE… ‘Power’ is only one of the metrics we should consider. Shall we consider EUE? environment usage effectiveness?? 01:13:23 Jaime Comella (C&H): There is already WUE as a metric 01:13:33 Jaime Comella (C&H): WUE, ERE, PUE 01:13:36 John Gross, JMGE: We do have WUE for water usage effectiveness, which gives us initial coverage over the two most critical resources for the site use. 01:14:48 Conrad, Peter: What are the temperature ranges that we are talking about? 01:15:11 Jaime Comella (C&H): low temperatures: 30-40 °C 01:15:16 Cosimo Pecchioli: low grade is around 30C, high grade is 50C and above 01:17:00 Conrad, Peter: You guys were discussing beer - the brewing process needs roughly 65C for mashing grains - sounds to me like this could be a very symbiotic relationship. 01:17:13 Jaime Comella (C&H): definitely 01:17:23 Jaime Comella (C&H): it is one of the industrial use cases 01:38:07 Steve Helvie: Will these BIM models become OCP contributions...or will it be a component of a larger Spec that may be contributed by a vendor? 01:39:45 Gaby Mindreci m-i2i.com: Great topic, but sorry, I have to drop off. 01:41:09 Don Mitchell: The immediate goal is a library of vendor provided BIM models. 01:44:03 Cosimo Pecchioli: not to toot my own horn, but something along these lines: https://www.bimobject.com/en-us/alfa-laval 01:44:17 Joshua Au: I wonder if this might change how CFD might work in conjunction with DCIM. Perhaps some of the data of the BIM could make the CFD assessments more realistic 01:56:10 Paul Isherwood: 18:05 here in England 02:11:25 Vadim Heyfitch: Any consideration for earthquakes when choosing a type of connection to use? 02:14:22 Don Mitchell: Seismic and pipe movement are key aspects of holistic design considerations 02:20:20 Paul Gwin (Intel): Something to consider is semiconductor fabs utilize well established industry proven standards and also have significant alignment in piping, connections, etc to liquid cooling in data centers. Do the practices here align with semi fabs best known methods (very similar in connections) - is it prudent to cross reference BKM's from a well established similar industry? 02:25:47 Cosimo Pecchioli: Link here too: 02:25:50 Cosimo Pecchioli: https://www.opencompute.org/wiki/Data_Center_Facility/Heat_Reuse 02:44:50 Gaby Mindreci m-i2i.com: LoL... steeping corn apparently is done at 50ºC, it is a big industry, it may be worthwhile checking into it 02:50:55 Gaby Mindreci m-i2i.com: 🙂👍🏼 02:51:10 Jaime Comella (C&H): 🌽 02:52:50 Gaby Mindreci m-i2i.com: https://en.wikipedia.org/wiki/Corn_wet-milling 03:28:45 Gaby Mindreci m-i2i.com: Bye to all!
