-1C - Erasure Encoding as a Storage Backend¶
xiaoxi I cannot see anyone & any words,it's all blank 09:00 loicd sjust: \o 09:00 loicd that's what the summit is for, right ? ;-) 09:01 *** rturk is now known as rturk-away 09:01 *** rturk-away is now known as rturk 09:01 loicd http://wiki.ceph.com/01Planning/02Blueprints/Dumpling/Erasure_encoding_as_a_storage_backend 09:01 loicd http://pad.ceph.com/p/Erasure_encoding_as_a_storage_backend 09:02 *** sjustlaptop has joined #ceph-summit1 09:02 sagewk anybody else want to join the hangout? 09:03 nwl in future, i wonder if it's better to keep the blueprint out of the etherpad 09:04 nwl so one can just see the changes/comments etc 09:04 rturk the etherpad only contains the work items 09:04 rturk but ya, maybe it should just be for notes? 09:04 nwl rturk: yeah, so the notes can be then fed back into the blueprint, redmine etc 09:05 rturk (ideas welcome -> community@ceph.com, now or anytime!) 09:05 saras have you look at http://www.opencompute.org/projects/storage/ 09:05 *** liwang has joined #ceph-summit1 09:06 dmick saras: I have not; did you mean relative to the management API work specifically, or in general? 09:09 nwl saras: sage is involved in the project 09:09 saras thanks 09:10 nwl saras: we are not doing anything very actively though (as Inktank) 09:10 saras can you guy setup lower thirds 09:11 saras please 09:11 rturk lost your audio, loicd 09:12 yehuda_hm in practice an osd should not become full, unless something is misconfigured, or the entire cluster filled up 09:12 loicd damned 09:13 loicd ahahah 09:13 loicd I'm back 09:13 saras append would be great 09:13 *** maclin has joined #ceph-summit1 09:16 hskinner erasure encoding is of course most valuable with geo-dispersment 09:17 sagewk hskinner: true 09:17 sagewk it's also not latency-sensitive in this use case... 09:17 hskinner yes, ability to migrate to optimal region locality would be bonus 09:18 ksp erasure encoding is also valuable in metro cluster/distance; e.g. EMC Isilon OneFS is using such algorithms 09:21 saras is their paper that i can read about erasure encoding 09:22 dmick saras: a bunch of resources on http://wiki.ceph.com/01Planning/02Blueprints/Dumpling/Erasure_encoding_as_a_storage_backend 09:24 saras dmick: thanks 09:24 *** michael__ has joined #ceph-summit1 09:24 *** michael__ has quit IRC 09:24 *** yanzheng has quit IRC 09:26 *** michael_dreamhost has joined #ceph-summit1 09:26 ksp http://en.wikipedia.org/wiki/Erasure_code 09:27 *** yanzheng has joined #ceph-summit1 09:27 saras pg to be clear 09:28
