shaohe_fengzhenguo: will we support multi pod manager?08:17
shaohe_fengzhenguo: then how to configure them? and how to schedule them?08:17
shaohe_fengzhenguo: just RR iterate?08:19
zhenguoshaohe_feng: not sure, if we schedule multi podm, it's more like a nova scheduling08:21
shaohe_fengzhenguo: we start only one pod?08:54
zhenguoshaohe_feng: do you know how pure RSD users manage multi podm?08:57
shaohe_fengzhenguo: no, at present. now, our developer just use on podm09:03
zhenguoshaohe_feng: so, I think we can just make one podm work :D09:04

openstackgerritShaoHe Feng proposed openstack/mogan master: [RSD SUPPORT] add rsd conf  https://review.openstack.org/52412310:27
shaohe_fengzhenguo: shall we support batch server create for RSD?10:43
shaohe_fengzhenguo: if one of server failure, what should we do?10:43
zhenguoshaohe_feng: IMO, we should just follow what we do for common servers10:44
shaohe_fengzhenguo: common servers, will destroy all?10:45
zhenguoshaohe_feng: no10:45
zhenguoshaohe_feng: we have a min, max10:46
shaohe_fengthen what will it do?10:46
zhenguoshaohe_feng: if you reach the min number, then it will succeed10:46
shaohe_fengzhenguo: OK, so there is a min number10:47
zhenguoshaohe_feng: but that check happened before real creation :(10:47
zhenguoshaohe_feng: not sure how should we handle composing failure10:47
shaohe_fengzhenguo: if less than min number, what should we do?10:47
zhenguoshaohe_feng: seems that's just quota check10:47
shaohe_fengzhenguo: yes, I'm thinking about composing failure.10:47
shaohe_fengzhenguo: for batch create, it will failure during composing10:48
shaohe_fengzhenguo: for example, user want to create 5 server,10:48
shaohe_fengonly compose 3, what should we do?10:48
zhenguoshaohe_feng: podM support butch compsing?10:48
zhenguoshaohe_feng: or you will request 3 times10:48
shaohe_fengzhenguo: I'm not sure, we mogan can help to call podM compse  5 times.10:49
zhenguoshaohe_feng: if so, maybe retry if one request failed?10:51
shaohe_fengzhenguo: do our mogan support batch create for common server?10:51
zhenguoshaohe_feng: yes10:51
shaohe_fengzhenguo: OK, so RSD should support batch create.10:52
shaohe_fengzhenguo: what's the parameters would you like.10:53
zhenguoshaohe_feng: not sure what parameters podM supported10:54
shaohe_fengzhenguo: I means mogan create API.10:54
shaohe_fengzhenguo: I know podM10:54
zhenguoshaohe_feng: yes, depends on what parameters you need10:54
zhenguoshaohe_feng: you can define a new pattern regardless of flavor thing10:55
shaohe_fengzhenguo: it support very details parameters. not only cpu numbers, but also Frequence10:55
shaohe_fengand others.10:55
zhenguoshaohe_feng: what's the mini set of parameters10:56
shaohe_fengsame with RAM, and others10:56
shaohe_fengzhenguo: let me show you a redfish api10:56
shaohe_fengzhenguo: https://www.intel.com/content/dam/www/public/us/en/documents/technical-specifications/pod-manager-api-specification.pdf10:58
zhenguoshaohe_feng: maybe we can define some traits10:59
zhenguoshaohe_feng: users can list the traits we supported11:00
shaohe_fengzhenguo: page 3511:00
shaohe_feng4.11.1.411:00
shaohe_fengzhenguo: only admin define traits?11:01
shaohe_fengzhenguo: right?11:01
zhenguoshaohe_eng: yes11:01
zhenguoshaohe_feng: yes11:02
zhenguoshaohe_feng: something like DISK_SSD_500GB?11:02
shaohe_fengzhenguo: so the data center purchase some RSD, they are same cpu and ram specfic11:02
shaohe_fengzhenguo: then they tag it CPU_E5_V3_2.2G, RAM_2.3G, DISK_NVME11:03
shaohe_fengand purchase another RSD with the different specfic of the previous11:04
shaohe_fengzhenguo: then tag it CPU_E5_V4_2.4G, RAM_2.4G, DISK_NVDIMM11:05
shaohe_fengzhenguo: riht?11:05
zhenguoshaohe_feng: yes, wdyt?11:05
shaohe_fengzhenguo: agree, I just wonder can we detect the hadware specfic automatically´╝č11:07
shaohe_fengzhenguo: then mongan can help to tag the traits?11:08
zhenguoshaohe_feng: does PodM support that?11:08
shaohe_fengzhenguo: I think redfish can support, let me check with lin.11:09
