Hi all,
A few months ago we discussed feature requirements for future tape drives. One of the actions was for the team to draft a document and list the supporting companies at the bottom of the document. I would encourage everyone to review the document and comment where you see fit and add your company's name to the bottom of the list if you support this feature request.

Canceling the next two Tape Durability Modeling Calls

Michael Schill
 

Hi all,

We are canceling the next two occurrences while we try to find volunteers to help drive this forward. Some have expressed interest and work in the durability modeling space that will hopefully have the ability to bring the effort and move it forward. 

Thanks,

Tape Durability workgroup updates

Jason Adrian
 

Hi all,
We are going to pause the tape durability calls for a few weeks, and resume them in June. We have a few people interested in bringing some new ideas to the table, but will need time to work through this beforehand. You should see a cancellation for today;s call and the next 2 occurrences.

Re: 4/9 Tape Durability Call

Jason Adrian
 

Hi all,
Since I didn't get any emails with topics for today, let's cancel this occurrence. If we want to keep the tape durability effort moving forward, we will need to bring in new ideas and areas to discuss. As previous calls have discussed, the problem is complex, and there are no obvious answers. However, by working together and looking at very large data sets, we should in theory be able to at least move in the right direction, even if there is no clear cut answer or model. 

Please reach out to the mailing list, or me directly if you have ideas or suggestions.

Jason

Hi Jason,

Happy to moderate, but will need topics for the agenda. If there are no issues to discuss, then maybe we should cancel.

Hi All,
Do we have any new topics for the 4/9 call? Gordon is on vacation, and I have a conflict. We can choose to cancel this occurrence unless others have topics or would be willing to host the meeting?

Storage call on 4/11 - request for topics

Jason Adrian
 

Hi all,
I hope everyone enjoyed the summit in San Jose a few weeks ago. All of the presentations were recorded and can be found via the schedule here: https://2019ocpglobalsummit.sched.com/overview/type/EW%3A+Storage 

There were announcements during the summit around some upcoming contributions that we will bring into the group in the coming meetings. Please reach out to Jorge and I if you have proposals for the 4/11 call, and we will get an agenda out a few days prior to the call.

Storage Wiki updates & February call slides

Jason Adrian
 

Hi All,
Thanks to Michael, we worked on cleaning up the Storage wiki to make things easier to navigate, including finding the sub-projects such as archival storage tracks. 

You can find the main landing page in the same place here, but it is much more streamlined and hopefully easier to navigate. ( https://www.opencompute.org/wiki/Storage )

One of the sub-pages now combines the monthly call presentations and the face to face meetings. The direct link is here, where you can also find the presentations from the last call: https://www.opencompute.org/wiki/Storage_Presentations_and_In_Person_Meetings#Storage_Presentations_and_In_Person_Meetings 

If you have any questions, feedback, etc, please let us know how we can organize the wiki to make things easier to find.

Regards,
Jason


2/12/2019 Tape Durability call recording

Jason Adrian
 

Hi everyone,
The recording for today's call is located below. We're starting to get many voices involved now, both from the customer use case and the technology providers. Great to see this effort starting to gain some traction. 

Thank you again to Vladamir for today's presentation!

reminder: 9am PST tape durability call today

Jason Adrian
 

Hi all,
Just a reminder that we moved this instance of the tape durability call to accommodate a presentation by Vladimir from CERN on their tape study paper. Hope to see you all in an hour.

Re: Tape Durability call today @ 4PM PST

Vladimir Bahyl
 

Dear Jason,

Tuesday 12 February 2019 starting 18:00 CET (Zurich, Switzerland time)
would work for me.

I can prepare few slides about what we have done, let me know what
platform will you use to share them.

Best regards,

Vladimir

According to Jason Adrian:

Hi Vladimir and others on the mailing list, how would moving one of the
occurrences to 9am PST (6PM in Zurich) work? The next meeting is 2/12 (next
week). Vladimir, if that works for you, we can move the 2/12 occurrence.

Dear Jason,

I could summarise the work CERN has done with the SCSI monitoring at
one of the next bi-weekly calls.

However, I would appreciate if the call could be during working hours
in Europe or at least not in the middle of the night.

When is the next call? Can it be moved in time?

Best regards,

Vladimir
