dachary | bauzas: https://wiki.openstack.org/wiki/OpenStack_Upstream_Training/Setup_DevStack on va utiliser ça pour init les devstack des participants qui seront en difficulté. | 13:40 |
---|---|---|
dachary | sileht: va me montrer comment faire sur l'infrastructure de http://tetaneutral.net/ | 13:41 |
bauzas | dachary: ca me va | 13:42 |

pfreund_ | quelqu'un aurait un bon doc sur le type de matos à acheter pour faire du stockage objet ? (ceph / swift, plutot swift dans un premier temps) | 14:32 |
pfreund_ | type de disques, ratios CPU/RAM/DISK, type de serveurs, etc | 14:32 |
pfreund_ | dachary: aurais-tu une bonne référence pour du ceph ? (hello ^^) | 14:33 |

dachary | pfreund_: l'infrastructure de http://tetaneutral.net/ est un bon exemple | 14:45 |
dachary | http://chiliproject.tetaneutral.net/projects/tetaneutral/wiki/Openstack_Installation_TTNN | 14:45 |
dachary | je ne sais pas si le materiel est document'e qq part sileht ? | 14:45 |
sileht | dachary, http://chiliproject.tetaneutral.net/projects/tetaneutral/wiki/Openstack | 14:46 |
dachary | pfreund_: mais ,ca depend vraiment de ce que tu veux faire en fait | 14:46 |
sileht | http://chiliproject.tetaneutral.net/projects/tetaneutral/wiki/Openstack#Ressources | 14:46 |
dachary | sileht: merci ! | 14:46 |
pfreund_ | dachary: merci je vais regarder | 14:46 |
dachary | pfreund_: avec Ceph tu peux tailler ton materiel au plus juste de ton usage. C'est pour faire quoi ? | 14:46 |
sileht | dachary, c'est pas à jour, on a rajouté 2 machines avec plein de disque/ssd en plus | 14:47 |
dachary | ok | 14:47 |
pfreund_ | dachary: fournir du stockage objet sur de l'openstack | 14:48 |
dachary | ok donc API swift / S3 ? pour quel genre d'usage ? | 14:48 |
pfreund_ | on va lancer des stacks sur de l'openstack, et dans les ressources de la stack il y a un container pour plein de trucs, logs/backups/ potentiellement des fichiers de l'appli | 14:51 |
*** pasquier-s has joined #openstack-fr | 14:52 | |
dachary | c'est quoi des stacks pfreund_ ? | 14:56 |
dachary | donc j'imagine que c'est du swift | 14:57 |
dachary | tu sais combien il y aura de debit en ecriture sur les backups / logs ? | 14:59 |
dachary | ou le nombre de machines virtuelles / physiques qui vont ecrire des logs / faire des backups | 14:59 |
dachary | pour avoir un ordre de grandeur | 15:00 |
dachary | logs et backups c'est plutot froid comme utilisation donc tu voudras qqc d'assez different de ttn qui utilise Ceph pour les disques des VM | 15:01 |
pfreund_ | pour le moment on ne peut pas mesurer | 15:01 |
pfreund_ | ce que j'entends par "stack", c'est un ensemble de ressources isolés qui fournit un service web, par exemple mediawiki | 15:02 |
pfreund_ | (dns / loadbalancer / serveurs / bdd / et un bucket par exemple) | 15:03 |

pfreund_ | dachary: tetaneutral c'est une infra plutot petite, je pensais plutot à une infra qui pourrait aller jusqu'au péta. | 15:22 |
pfreund_ | avec un début à 100 To | 15:22 |
dachary | pfreund_: l'infra de ttn ira jusqu'au peta ;-) | 15:22 |
pfreund_ | ah ok :) | 15:23 |
dachary | pfreund_: tu as une idée du débit en ecriture ? | 15:23 |
pfreund_ | pas encore, je vais pouvoir mesurer vers novembre | 15:23 |
dachary | global, au debut. c'est genre 1MB/s en continu ? 1GB/s ? | 15:23 |
dachary | pfreund_: tu as une idée de l'ordre de grandeur j'imagine | 15:24 |
pfreund_ | je sais exactement ce qui va tourner dessus, mais aucune idée du débit que ca va utiliser pour le stockage objet | 15:25 |
pfreund_ | je vais essayer de mesurer ca avant de penser au matos | 15:25 |
dachary | il faut au moins que tu ai l'ordre de grandeur avant de te décider pour l'architecture, tu penses pas ? | 15:25 |
dachary | voila, bonne idee | 15:25 |
