TL;DR;<\/strong> De instelling van de koelmodus van de Supermicro-server zorgt niet voor een stabiele werking van de LSI MegaRAID 9361-8i-controller in een koud datacenter.<\/p>\n

<\/p>\n

We proberen geen hardware RAID-controllers te gebruiken, maar we hebben een klant die de voorkeur geeft aan configuraties met LSI MegaRAID. Vandaag kregen we te maken met oververhitting van de MegaRAID 9361-8i kaart, omdat het platform geen gevoel had<\/strong> voor de oververhitting, terwijl de RAID-controller die wel voelde<\/strong>.<\/p>\n

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

De afbeelding van het platform met de RAID-kaart is hieronder weergegeven:<\/p>\n

\"Korte<\/p>\n

<\/p>\n

\"Korte<\/p>\n

<\/p>\n

Enkele belangrijke punten hierover server<\/a> en de gebruiksomgeving:<\/p>\n

<\/p>\n

De ingenieur die het platform heeft opgebouwd, heeft speciaal twee ventilatoren tegenover de kaart geplaatst, omdat hij weet dat LSI-controllers sterk opwarmen. Let op het moederbord; het komt praktisch niet tot de controller, het eindigt op 3 cm na de PCI-E-sleuf.<\/p>\n

<\/p>\n

Zoals u kunt zien, zijn alle ventilatoren normaal aangesloten op het Supermicro moederbord en functioneren zij in de modus Optimal<\/strong> \"blazen\" afhankelijk van de sensoren op de CPU, temperatuur.<\/p>\n

<\/p>\n

In dit platform is een Xeon E-2236 ge\u00efnstalleerd \u2014 een vrij koele CPU, die bij de klant blijkbaar niet veel is opgewarmd.<\/p>\n

<\/p>\n

Het datacenter waarin deze server zich bevindt is vrij koud \u2014 de koude gang biedt 18-20 graden.<\/p>\n

<\/p>\n

De combinatie van deze factoren leidde tot een interessant fenomeen \u2014 de oververhitting van de RAID-controller.<\/p>\n

<\/p>\n

De waarschijnlijke keten van hoe dit is gebeurd<\/h3>\n

<\/p>\n

    \n
  1. koude processor en moederbord gaven de ventilatoren door dat ze zwak konden blazen.<\/li>\n
  2. Het moederbord onder de RAID was afwezig en er waren geen sensoren die de oververhitting konden vastleggen.<\/li>\n
  3. De ventilatoren, die geconfigureerd zijn, bliezen in de modus Optimal zwak, volgens de behoeften van het moederbord en de CPU.<\/li>\n
  4. De controller, die niet genoeg luchtstroom kreeg, oververhitte.<\/li>\n<\/ol>\n

    <\/p>\n

    Wat we deden<\/h3>\n

    <\/p>\n

    We hebben de ventilatoren in de \"Standaard\" modus gezet, indien nodig schakelen we over naar een hogere prestatiemodus.<\/p>\n

    <\/p>\n

    Conclusies<\/h3>\n

    <\/p>\n

    Waarschijnlijk, als de koude gang van het datacenter niet zo koud was geweest, of als de klant de CPU intensief had gebruikt, zou dit probleem zich misschien niet hebben voorgedaan, omdat de ventilatoren in een intensievere modus zouden hebben gewerkt.<\/p>\n

    <\/p>\n

    Voor onszelf hebben we besloten om de ventilatormodus van servers<\/a> de RAID van Optimal naar een hogere snelheid modus te wijzigen.<\/p>\n
