Ceph Day Sunnyvale Presentations

Ceph Day Sunnyvale Presentations

[Patrick McGarry]

Hey cephers,

I have all but one of the presentations from Ceph Day Sunnyvale, so
rather than wait for a full hand I went ahead and posted the link to
the slides on the event page:

http://ceph.com/cephdays/ceph-day-sunnyvale/

The videos probably wont be processed until after next week, but I’ll
add those once we get them. Thanks to all of the presenters and
attendees that made this another great event.

Hi,

I was reading this presentation from SK telecom about flash optimisations

AFCeph: Ceph Performance Analysis & Improvement on Flash [Slides]
http://fr.slideshare.net/Inktank_Ceph/af-ceph-ceph-performance-analysis-and-improvement-on-flash
Byung-Su Park, SK Telecom


They seem to have made optimisations in ceph code. Is there any patches reference ? (applied to infernalis/jewel ?)


They seem also to have done ceph config tuning and system tunning, but no config details is provided :(
It could be great to share with the community :)

Regards,

Alexandre

Alexandre,

Based on discussion with them at Ceph day in Tokyo JP, they have their own frozen the Ceph repository.
And they've been optimizing codes by their own team to meet their requirements.
AFAICT they had not done any do PR. 

Cheers,
Shinobu

I have read the SK‘s performance tuning work too, it's a good
job especially the analysis of write/read latancy on OSD.
I want to ask a question about the optimize on 'Long logging time', what's
the meaning about 'split logging into another thread and do it later',
AFAIK, ceph does logging async by logging thread.
Can you share more info?
