Hi all,

Last week’s working session minutes attached.

 

The thought last week is we give ourselves a week to think thru the proposal and meet again during this week’s monthly sub-group meeting.  

 

  • Action item: Nvidia/Dell/HPE/Intel to get together brainstorm scalable height EMI face plate solutions
  • Action item: HPE to share case study of next gen hot aisle implementation using standard form factor
  • Proposal to be included in survey for feedback: Move forward with TFF (17.8mm) and provision for dual height to tackle cases whereby TFF unable to satisfy.
    • TFF fully utilized 1RU space
    • TFF can be paired with PCIe CEM in 1OU space
    • Dual TFF is forward looking and we system vendor can decide when to support dual TFF cards

Hi Haifang,

The purpose of dual height TFF is a catch all for what TFF cannot cover today:

  1. OSFP
  2. 400G for system that unable or unwilling to provide 700+ LFM
  3. 800G

 

Despite ETFF (20.1mm) helps in above use-cases, there are a lot of use-case that can be satisfied by TFF (17.8mm) in the near future.

 

Ability to stack two TFF is key for this form factor to be used more than just NIC.

Another thing is TFF can still stack with PCIe CEM in 1 OpenRack unit.

 

There was a discussion whether we will need to go to ETFF in the future and whether we just increase to ETFF now.

Hence the proposal is we do not go ETFF (20.1mm), when we need taller than TFF (17.8mm) then we go dual height.

 

This is just a proposal to be discussed tomorrow.

 

All, please feedback and thanks Haifang for doing this.

Hi all,

Last week’s working session minutes attached.

 

The thought last week is we give ourselves a week to think thru the proposal and meet again during this week’s monthly sub-group meeting.  

 

  • Action item: Nvidia/Dell/HPE/Intel to get together brainstorm scalable height EMI face plate solutions
  • Action item: HPE to share case study of next gen hot aisle implementation using standard form factor
  • Proposal to be included in survey for feedback: Move forward with TFF (17.8mm) and provision for dual height to tackle cases whereby TFF unable to satisfy.
    • TFF fully utilized 1RU space
    • TFF can be paired with PCIe CEM in 1OU space
    • Dual TFF is forward looking and we system vendor can decide when to support dual TFF cards

[EXTERNAL EMAIL]

Hi all,

Last week’s working session minutes attached.

 

The thought last week is we give ourselves a week to think thru the proposal and meet again during this week’s monthly sub-group meeting.  

 

  • Action item: Nvidia/Dell/HPE/Intel to get together brainstorm scalable height EMI face plate solutions
  • Action item: HPE to share case study of next gen hot aisle implementation using standard form factor
  • Proposal to be included in survey for feedback: Move forward with TFF (17.8mm) and provision for dual height to tackle cases whereby TFF unable to satisfy.
    • TFF fully utilized 1RU space
    • TFF can be paired with PCIe CEM in 1OU space
    • Dual TFF is forward looking and we system vendor can decide when to support dual TFF cards
