OCP Positive Disruption of the Datacenter Hardware Ecosystem V2
Download as PPTX, PDF0 likes583 views
This document discusses positive disruptions to the traditional data center hardware ecosystem in the 21st century. It questions many common 20th century practices like using 19-inch racks, rear server cabling, raised floors, tight temperature controls, centralized UPS and battery rooms. It argues these were based on human design constraints but newer more open source and modular designs remove these limitations. The document aims to reset mindsets around data center design and operations for simpler, more resilient and sustainable solutions using open standards.

- 2. John Laban European Representative Reset Catalyst OCP Foundation @rumperedis 2
- 6. Subject title for Paulo’s email was Wilful Blindness !!
- 7. Laban’s job title is Reset Catalyst Kubler-Ross Change Curve Hold tight and get ready for my 21st century roller coaster bare knuckle ride at the OCP Data Centre World
- 8. Discrediting 20th Century Data Centres Why 19 inch racks ? Why cabling interfaces on the rear of servers ? Why access false floors in computer rooms ? Why tight control on relative humidity and temperature ? Why centralised UPS and battery rooms and mechanical chillers ? Why rapid break fix and hardware redundancy ? 8
- 9. Why 19 inch relay racks ? 9 Module Container
- 10. Why 19 inch racks… are not sacrosanct 10 Module see also Penguin 1/3 OCP servers Container
- 11. This human design makes sense 11 Module Container
- 12. Why are cabling interfaces on the rear of servers ? 12 LAN on front
- 13. Why access false floors in computer rooms ? 13
- 14. Why tight control on relative humidity and temperature ? 14 Heat aging and constrained air flows with 40mm fans
- 15. Why centralised UPS and battery rooms and mechanical chillers ? 15Thanks to Kushagra Vaid for graphics

- 20. Why rapid break fix and hardware redundancy ? 20 Screws x nuts x washers = tools x tools Complex = infinite rack configurations Complex = maximum materials Resilience = hardware redundancy Green Touch points = no tools Simple = just six rack configurations Simple = minimal materials Resilience = software & chaos monkey proof 20th Century 21th Century
- 21. Open Source Ethernet Clos Fabrics & SDN These remove the need for urgent break fix maintenance ask these guys why I can fix the component next week ?

Editor's Notes
- #2: Initially developed for Oct 2016 Frankfurt which was the first OCP event in Germany
- #3: Discrediting the traditional 20th century computer room practices ......a few teaser questions.... Reset Catalyst has …..Nothing to do with resetting proprietary cisco catalyst switches..its about mindsets
- #4: Ciara please stand up! And thanks to you all for coming ..talking to the rear wall is not so much fun !
- #5: Had my eureka OCP moment had when working at the Facebook data centre in Lulea Sweden. My mission is to tell the data centre industry about OCP solutions and to be a Reset Catalyst to move the 20th century data centre industry into the 21st century.
- #6: Email from Paulo (not his real name!) six days before the Frankfurt OCP event. Scribbled out his details to protect him. Paulo sells down flow CRAC cooling systems for enterprise data centres. He called his email “willfull blindness”
- #7: Read the book willful blindness….you will then understand what Paulo means!
- #8: Get ready for a 21st century roller coaster bare knuckle ride at Data Centre World I might be killing off your babies in the nest fifteen minutes!
- #9: Discrediting the traditional 20th century computer room practices ......a few teaser questions.... From the point of view of the 21st century what we did in the 20th century is lamentable and oh, oh, oh so wasteful and downright stupid.
- #10: 19ich width great for telegraph and railway electromechanical relays. Show of hands …how many of you are fitting relays like these into your data centre computer room racks…yes a big no!
- #11: OCP wide uses cabinet allows 25% increase in in HDDs . Width was more than optimising for 4inch wide HDD….see Amir email with reasons relating to the Freedom server. See the OCP third width servers on display outside of this room. Open Vault (old name Knox) offers high disk densities, holding 30 drives in a 2U chassis. Increasing rail widths does not increase overall width of rack so they would still fit a 2ft floor grid http://www.opencompute.org/blog/introducing-the-open-rack/
- #12: See my “screws screws screws why we do the things we do” presentation from Data Centre Conference South at the Barbican in 2015. This presentation takes it to a Monty Pyhonist level of ridiculous humour with candles and chickens. When people laugh there mindsets become malleable Barbican presentation available on request from john.laban@jrlaban.com
- #13: OCP server value engineering Cables on rear because started as a desk top PC befor being placed in a rack on a shelf.
- #14: Used for water pipes and not air cooling. Water pipes below so when they leaked the mainframe did not go pop! Air buoyancy means its better practice to pour cool denser air down into warmer room, and not blow it up from the bottom. Note printers and seat/desk positions for people in room. Back then people did not use black racks!!!!
- #15: Paper curls and jams printers in computer room if wide range of humidity. Paper today still has an up and down and should be placed in printers the right way up.
- #16: 3D graphic and next few slide provided by OCP_US2015_KushagraVaid_Microsoft_Keynote_final.pdf Available from John Laban or the OCP web site wiki and YouTube channel
- #19: LES uses Li-ion BBU (Battery Backup Unit) in white space rack/chassis
- #20: Slide taken from Kushagra’s OCP Summit 2015 keynote. LES = Local Energy Storage ; UPS in the computer room rack. MS OCP solutions puts Li-ion in server and storage chassis and other OCP solutions collocate with rectifier shelves in OCP open V2 racks.
- #22: Leads into their presentations at the Frankfurt event Mention impact of ocp on support staffing levels in data centres …a 99% reduction compared to 20th century designs and practices
- #23: Acceptance of the death does not occur until one has been through the earlier emotions. Reset Catalyst ….resetting peoples 20th century data centre mindsets so they can move on into the 21st century’s open source data centres
- #24: CE0 of a Black Box proprietary hardware solutions that lock-in the user and benefit the few at the expense of the majority
- #25: Discrediting the traditional 20th century computer room practices ......a few teaser questions.... Nothing to do with resetting proprietary cisco catalyst switches
- #29: This is a primer for the following presenters who will cover CORD and the telco transformation to OCP virtualised data centres
