TL;DR;<\/strong> La configuration du mode de fonctionnement du syst\u00e8me de refroidissement du serveur Supermicro Optimal ne garantit pas la stabilit\u00e9 du contr\u00f4leur LSI MegaRAID 9361-8i dans un Data Center froid.<\/p>\n

<\/p>\n

Nous essayons d'\u00e9viter l'utilisation de contr\u00f4leurs RAID mat\u00e9riels, mais nous avons un client qui pr\u00e9f\u00e8re sp\u00e9cifiquement les configurations avec LSI MegaRAID. Aujourd'hui, nous avons rencontr\u00e9 un probl\u00e8me de surchauffe de la carte MegaRAID 9361-8i en raison du fait que la plateforme ne d\u00e9tectait pas<\/strong> la surchauffe, alors que le contr\u00f4leur RAID la d\u00e9tectait.<\/strong>.<\/p>\n

<\/a><\/noindex><\/p>\n

La vue de la plateforme avec la carte RAID est pr\u00e9sent\u00e9e dans les illustrations ci-dessous :<\/p>\n

<\/p>\n

\"Note<\/p>\n

<\/p>\n

\"Note<\/p>\n

<\/p>\n

Quelques points importants concernant cela serveur<\/a> et l'environnement d'exploitation :<\/p>\n

<\/p>\n

L'ing\u00e9nieur qui a assembl\u00e9 la plateforme a d\u00e9lib\u00e9r\u00e9ment plac\u00e9 deux ventilateurs en face de la carte, car il sait que les contr\u00f4leurs LSI chauffent beaucoup. Notez que la carte m\u00e8re n'atteint pratiquement pas le contr\u00f4leur, se terminant environ 3 cm apr\u00e8s le slot PCI-E.<\/p>\n

<\/p>\n

Comme vous pouvez le voir, tous les ventilateurs sont branch\u00e9s normalement sur la carte m\u00e8re Supermicro et en mode Optimal<\/strong> \"soufflent\" en fonction des capteurs \u00e0 bord, de la temp\u00e9rature du CPU.<\/p>\n

<\/p>\n

Cette plateforme est \u00e9quip\u00e9e d'un Xeon E-2236 - un CPU assez froid, qui, visiblement, ne s'est pas beaucoup \u00e9chauff\u00e9 chez le client.<\/p>\n

<\/p>\n

Le Data Center o\u00f9 se trouve ce serveur est tr\u00e8s froid - le couloir froid donne des temp\u00e9ratures de 18 \u00e0 20 degr\u00e9s.<\/p>\n

<\/p>\n

La combinaison de ces facteurs a conduit \u00e0 un ph\u00e9nom\u00e8ne tr\u00e8s int\u00e9ressant - la surchauffe du contr\u00f4leur RAID.<\/p>\n

<\/p>\n

La cha\u00eene probable de comment cela s'est produit<\/h3>\n

<\/p>\n

    \n
  1. le processeur froid et la carte m\u00e8re faisaient savoir aux ventilateurs qu'ils pouvaient souffler faiblement.<\/li>\n
  2. la carte m\u00e8re sous le RAID \u00e9tait absente et il n'y avait pas de capteurs pour d\u00e9tecter la surchauffe.<\/li>\n
  3. Les ventilateurs, \u00e9tant configur\u00e9s, en mode Optimal, soufflaient faiblement, en fonction des besoins de la carte m\u00e8re et du CPU.<\/li>\n
  4. Le contr\u00f4leur, ne recevant pas un flux d'air suffisant, s'est surchauff\u00e9.<\/li>\n<\/ol>\n

    <\/p>\n

    Que avons-nous fait<\/h3>\n

    <\/p>\n

    Nous avons chang\u00e9 les ventilateurs en mode \"Standard\"; si n\u00e9cessaire, nous les passerons \u00e0 un mode de performance plus \u00e9lev\u00e9.<\/p>\n

    <\/p>\n

    Conclusions<\/h3>\n

    <\/p>\n

    Probablement, si le couloir froid du Data Center n'\u00e9tait pas aussi froid, ou si le client utilisait intensivement le CPU, ce probl\u00e8me n'aurait pas pu se produire, car les ventilateurs auraient fonctionn\u00e9 \u00e0 un r\u00e9gime plus intense.<\/p>\n

    <\/p>\n

    Pour nous, nous avons d\u00e9cid\u00e9 de changer absolument le mode de fonctionnement des ventilateurs \u00e0 serveurs<\/a> de RAID de Optimal \u00e0 un mode avec une fr\u00e9quence de rotation accrue.<\/p>\n
