4. Key mechanical updates: | |||
- Agreed on guiding feature and card sizes | |||
- Reduce to 2x sizes (Small and Large form factors; detail see latest spec draft) | |||
To be closed: | |||
- Front bracket / latching mechanism design for small and large form factors | |||
- Right Angle connector vertical offset(3.05mm vs. 3.50mm); Need to decide and close based on Tolerance analysis | |||
- Straddle Mount connector offset and PCB footprint; Need to decide and close based on 1U use case study | |||
5. Coming working sessions and proposal of agenda: | |||
-#7 12/6 : 2hr working session; ME and EE runs in parallel; close on ME opens and clarify the rest of draft work | |||
-#8 12/13: 3-4hr: All draft work due for 1st pass of edit of all chapters. 1st cross review with changes suggested and agreed | |||
-#9 12/20: 3-4hr: Review changes and post 1st draft | |||
'''11/20 update''' | |||
1. Updated specification(11/12) and pin definition(11/15) to the "updated doc session"; The spec still needs a lot of work in the coming a few weeks. | |||
2. Thermal deck v7 is uploaded (same material as presented on 11/15) | |||
'''10/31 update''' | |||
1. We did 4x working session so far and made good progress in pinout and mechanical profile | |||
- 10/11 11:30am-3pm(PDT) - Done: TE/Dell-EMC/Intel/FB | |||
- 10/18 9am-2pm(PDT) - Done: TE/Dell-EMC/Lenovo/Broadcom/Intel/FB | |||
- 10/27 8am - 11am(PDT) Done: – TE/Dell-EMC/Lenovo/Broadcom/Intel/FB | |||
- 10/31 8:30am - 10am(PDT) Done: - (Pinout specific session) Mellanox / Broadcom / Intel / Dell-EMC / FB | |||
- 11/3 8am-11am(PDT) | |||
- 11/15 9am-5pm(PST) | |||
2. Latest pin out and ME deck are posted at [http://www.opencompute.org/wiki/Server/Mezz#Updated_doc Table above] | |||
3. Plan to post WIP specification draft after 11/3 workshop for broader review | |||
4. We will cancel the 2017/11/01 meeting as FB team has a conflict | |||
'''10/18 Update''' | |||
- Intel/Dell-EMC/TE/FB joined the spec drafting working session on 10/11 and worked on these topics: [http://files.opencompute.org/oc/public.php?service=files&t=089dc36e019eadfcbdc590837e7e0dc6 framework], sections, pinout, connector, specification drafting logistics. | |||
- With many inputs from community, FB updated Mechanical deck to v3; Key changes are 1) fine tuning module width by 2mm 2) proposing 1 extra sizes, and total 3x sizes with different width. Detail see [http://files.opencompute.org/oc/public.php?service=files&t=520161aaf734e0b8690a9003b73bd57c Mechanical Discussion_v03_20171018] | |||
- Pinout is being actively working on. Intel is taking lead on proposing and maintaining the draft; an updated version can be found [http://files.opencompute.org/oc/public.php?service=files&t=aa9736b73845229c4dcd6cf47c74296e [here]] | |||
- We will move from Fuze to GoToWebinar for project calls in Nov. 10/18 call is likely the last call on Fuze. More details to follow in mailing list and calendar. | |||
'''9/20 Update''' | |||
- The subgroup closed on all other major options after a few months of iterations. #14 is the clear preference in subgroup. Details and specification will be worked out around this option. | |||
