Hi Ross, 

I've noticed recently that both the throttle and overshoot temperature are the same, but we state that the drive should be operable without performance loss at up to 70°C. The throttling SPEC seemingly guarantees lossless performance up to 76°C. The SPEC should have the following update added: 


OP-TH-2 The SSD shall operate normally (without losing performance) with

composite temperature (measured by the thermal sensor) to be between

0 C and 70°C (should be changed to 0 °C and 76°C or 77°C depending on which action is taken below). 

TTHROTTLE-5 A composite temperature of 77 C (170.6 F) shall be used for throttling.


1) the drive is allowed to operate up to 76°C for < 1% of the year with throttling starting at 77°C. 
2) the drive is allowed to operate up to 77°C for < 1% of the year with throttling starting at 78°C. 

Regards,
Brandon G.

Agenda: OCP Storage Monthly - Thursday - December-09-2021 - 3-4pm Pacific

Dave Landsman
 

Hi,

This month, we are doing some “inter-OCP” collaboration updates.  That is, we have presentations from two other projects with comments/thoughts on Storage:

 

  1. Sustainability – Jonmichael Hands (Chia) will present on behalf of OCP Sustainability project on some aspects the team has been discussing regarding storage.
  2. Security re: Datacenter NVMe SSD – Arie van der Hoeven (or others from OCP Security) will present on gaps/conflicts between the SSD NVME specification and OCP Security Specs and suggest strategies for aligning the two projects.

 

Hope to “see” you on Thursday.  Dave

Cancelling tomorrow's OCP Storage Group Monthly

Dave Landsman
 

Well, we actually tried but with the OCP Summit coming there was no taker for a topic this month.  So, we are cancelling the October meeting tomorrow.  We will not do the November meeting due to the OCP Summit being the same week.  We do plan to have a presentation for the December monthly.  More on that as we get closer.   

 

Michael Schill, can you please cancel tomorrow’s OCP Storage monthly, and also the November monthly?  Thanks, Dave

 


HDD Vibration -- Thursday September 23 2021

Matt Shumway
 

Thursday September 23 4PM PST

Agenda:  
Two topics for this meeting from the FB team. 
  1. A Vibro-acoustical surrogate that FB recently built and have been testing with. This is mostly for inspiration for phase 2 of the workstream as we might have areas that need improvement. (20mins including Q&A)
  2. Multi-disciplinary optimization analysis (cost vs performance vs thermal, etc) to point at optimal chassis level solutions to reduce acoustical and structural vibrations at HDD. This is interesting on the simulation side and optimization side to help design a chassis without going through multiple revs of it. (30 mins including Q&A

Request for Survey Responses - Please share your opinion on Software-Defined Memory (SDM)

Michael Schill
 

Hi all,

We are still hoping for your help by completing a survey on Software-Defined Memory (SDM) . We have had a lot of good responses, but need a few more to reach our target sample size, and are holding the survey open for a short time. Your response would be very important to us in guiding our planning in how we can better serve our members and the community at large. We are reaching out in hopes of collecting insight into industry trends and requirements for memory needs in your infrastructure. 

Again, you can access the survey by clicking on this link: https://www.surveymonkey.com/r/5DRZFMX.  All your responses are kept confidential and all results are presented in aggregate, keeping your responses private.

If you have any concerns or questions prior to responding, please feel free to reach out.

We are skipping our September monthly

Dave Landsman
 

Hi all,

Well, Jason and I are both committing ourselves to not doing this, but we did not get to lining up an agenda for September.  We are going to for October, as some kind of pre-Summit thing. That’s a marker, being put down!!  Words may be eaten, but we intend not.  😊

 

So, no meeting tomorrow.  Michael, will you please take off the calendar.   Talk to you all in October.  Dave and Jason


HDD Vibration Meeting for Thursday August 26 2021

Matt Shumway
 

Thursday August 26 at 4PM PST

Agenda: 
  1. Call for demonstration results from the acoustic surrogate for the OCP Global Summit
  2. Complementary to our published paper, the team was working to publish the associated CAD, and Matt and Archna are still working through that, so I suspect Matt can give an update.
  3. Relevant vibration parameters – in last meeting Cathy had presented, and although I had offered to present this time, obviously I will be out, but others may have additional HDD Dynamics vibration data to discuss
  4. Timeline, milestones, and desired outcome of Phase 2 of OCP HDD Dynamics on vibration surrogate – it probably makes sense to clearly define these so we align upfront on expectations rather than, as occurred with the HDD Dynamics acoustical paper, found ourselves asking the questions as we were completing

Re: Confirmation: NVMe HDD Meeting Agenda for 8/19/2021 (tomorrow)

Mohamad Elbatal
 

Hi All,

After some internal discussions, Seagate decided to wait for Jason Adrian to come back before we continue the review of the proposed NVMe-HDD connector signals.
In the meantime, please comment on the existing OCP requirements doc.

Best,
Mohamad

Re: Topic for August OCP Storage meeting

Brandon,

 

I would encourage you to attend the OCP storage meetings.  This is a FB contribution based on FB hardware.  I would encourage MSFT to contribute their flash boxes to OCP to make them available to the entire community.

Hi Ross and team,

 

I think we should continue the trend of 9.5mm, 15mm, 25mm. Only considering 9.5mm and 25mm seems to be a vast oversight for those who may benefit from the utility of increased VM’s. That is to say the following:

 

9.5mm: provides the highest distribution of memory utilization at lower power for those who want to fully front load a server.

15mm: provides the balance between VM’s and memory performance.  

25mm: provides highest potential for both fast and VM limited solutions.

 

If we’re going to build standards around storage we should consider all applications and I think 9.5mm, 15mm, and 25mm provide widths that are applicable to corner cases amongst each heat sink height, mechanical integration, and E1.S qty. In addition to everything that I’ve typed above, adding back in 15mm will maintain consistency with the thermal validation document for E1.S.

 

Regards,

Brandon G.
