44 | 4 | Laurent GUERBY | |
45 | 4 | Laurent GUERBY | Calamari is a management and monitoring system for Ceph storage cluster. It provides a beautiful Dashboard User Interface that makes Ceph cluster monitoring amazingly simple and handy. Calamari was initially a part of Inktank’s Ceph Enterprise product offering and it has been open sourced few months back by Red Hat. Hence Calamari is a matured enterprise level software which is now Open Source. - See more at: http://ceph.com/category/calamari/#sthash.XpksGKGg.dpuf |

53 | 1 | Laurent GUERBY | <pre> |
54 | 1 | Laurent GUERBY | <mherrb> est-ce que l'un de vous connait CEPH ? (http://ceph.com et https://github.com/ceph) ? |
55 | 2 | Thierry Boudet | <djanos> mherrb: Je l’ai testé à INP-net/net7 |
56 | 5 | Laurent GUERBY | <djanos> On est finalement reparti sur du DRBD avec heartbeat. La haute disponibilité intégré dedans c’est assez pratique, |
57 | 5 | Laurent GUERBY | mais les perf n’étaient pas au rendez-vous. Mais j’ai peut-être pas assez passé de temps pour trouver les bon réglages. |
58 | 5 | Laurent GUERBY | Ceci dit, c’est Laurent qui nous en avait parlé, d’autre à ttn l’utilise je crois. |
59 | 5 | Laurent GUERBY | <sileht> ca marche bien et cote setup c'est facile d'avoir des mauvaises perfs, pour attendre le débit des disques |
60 | 5 | Laurent GUERBY | des machines du cluster, il faut mettre un SSD pour n disk |
61 | 1 | Laurent GUERBY | <sileht> n = IOPS_SSD/(nombre de disk * IOPS disk) |
62 | 2 | Thierry Boudet | <sileht> et décrire dans la conf de ceph comment sont connecté physique tes machines machines/disques/switches |
63 | 2 | Thierry Boudet | <sileht> c'est pas trivial mais une fois installé ca marche bien |
