TL;DR;<\/strong> Inst\u00e4llningen av kylsystemets arbetsl\u00e4ge p\u00e5 Supermicro-servern Optimal s\u00e4kerst\u00e4ller inte stabil drift av LSI MegaRAID 9361-8i-controllern i en kall datacenter.<\/p>\n

<\/p>\n

Vi f\u00f6rs\u00f6ker att inte anv\u00e4nda h\u00e5rdvaru-RAID-kontroller, men vi har en kund som f\u00f6redrar konfigurationer med LSI MegaRAID. I dag st\u00f6tte vi p\u00e5 \u00f6verhettning av MegaRAID 9361-8i-kortet p\u00e5 grund av att plattformen inte k\u00e4nde<\/strong> \u00f6verskottsv\u00e4rme, men RAID-kontrollern k\u00e4nde<\/strong>.<\/p>\n

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

Denna plattforms vy med RAID-kortet visas p\u00e5 bilderna nedan:<\/p>\n

\"Kort<\/p>\n

<\/p>\n

N\u00e5gra viktiga punkter relaterade till detta servern<\/a> och driftsmilj\u00f6n:<\/p>\n

<\/p>\n

Ingenj\u00f6ren som byggde plattformen satte speciellt tv\u00e5 fl\u00e4ktar mittemot kortet, eftersom han vet att LSI-kontrollerarna blir mycket varma. Observera moderkortet, det g\u00e5r knappt under kontrollern, utan slutar efter 3 cm efter PCI-E-slotten.<\/p>\n

<\/p>\n

Som ni ser \u00e4r alla fl\u00e4ktar korrekt anslutna till Supermicro-moderkortet och i l\u00e4get Optimal<\/strong> \"bl\u00e5ser\" beroende p\u00e5 sensorerna p\u00e5 den, CPU-temperatur.<\/p>\n

<\/p>\n

I denna plattform finns Xeon E-2236 \u2013 en mycket kall CPU, som troligen inte har blivit s\u00e5 varm hos kunden.<\/p>\n

<\/p>\n

Datacentret d\u00e4r denna server st\u00e5r \u00e4r mycket kallt \u2013 den kalla korridoren ger 18-20 grader.<\/p>\n

<\/p>\n

Kombinationen av dessa faktorer ledde till ett mycket intressant fenomen \u2013 \u00f6verhettning av RAID-kontrollern.<\/p>\n

<\/p>\n

Den troliga kedjan f\u00f6r hur detta h\u00e4nde<\/h3>\n

<\/p>\n

    \n
  1. den kalla processorn och moderkortet rapporterade till fl\u00e4ktarna att de kunde bl\u00e5sa svagt.<\/li>\n
  2. moderkortet under RAID:en saknades och det fanns inga sensorer som registrerade \u00f6verhettning.<\/li>\n
  3. Fl\u00e4ktarna, som var konfigurerade i l\u00e4get Optimal, bl\u00e5ste svagt, i enlighet med moderkortets och CPU:ns behov.<\/li>\n
  4. Kontrollern, utan att f\u00e5 tillr\u00e4cklig luftstr\u00f6m, \u00f6verhettades.<\/li>\n<\/ol>\n

    <\/p>\n

    Vad vi gjorde<\/h3>\n

    <\/p>\n

    Vi har st\u00e4llt in fl\u00e4ktarna p\u00e5 \"Standard\"-l\u00e4ge, och om det beh\u00f6vs kan vi byta till ett h\u00f6gre prestandal\u00e4ge.<\/p>\n

    <\/p>\n

    Slutsatser<\/h3>\n

    <\/p>\n

    Sannolikt om den kalla korridoren i datacentret inte hade varit s\u00e5 kall, eller om kunden hade anv\u00e4nt CPU:n intensivt, skulle detta problem kanske inte ha intr\u00e4ffat, eftersom fl\u00e4ktarna skulle ha fungerat i ett mer intensivt l\u00e4ge.<\/p>\n

    <\/p>\n

    F\u00f6r v\u00e5r del har vi beslutat att definitivt \u00e4ndra fl\u00e4ktarnas arbetsl\u00e4ge f\u00f6r servrar<\/a> med RAID fr\u00e5n Optimal till ett l\u00e4ge med h\u00f6gre rotationshastighet.<\/p>\n
