TL;DR;<\/strong> Serveri Supermicro Optimal jahutuss\u00fcsteemi t\u00f6\u00f6re\u017eiimi seadistamine ei tagada LSI kontrolleri MegaRAID 9361-8i stabiilset toimimist k\u00fclmas andmekeskuses.<\/p>\n

<\/p>\n

P\u00fc\u00fcdleme selle poole, et mitte kasutada RAID riistvarakontrolle, kuid meil on \u00fcks klient, kes eelistab just LSI MegaRAID konfiguratsioone. T\u00e4na kohtasime MegaRAID 9361-8i kaardi \u00fclekuumenemist, kuna platvorm ei tundnud<\/strong> \u00fclekuumenemist, kuid RAID-kontroller seda tundis.<\/strong>.<\/p>\n

<\/p>\n

M\u00f5ned t\u00e4htsad punktid, mis on seotud sellega serveriga<\/a> ja t\u00f6\u00f6tingimustega:<\/p>\n

<\/p>\n

Insener, kes platvormi kokku pani, paigaldas kaardi ette kaks ventilaatorit, teades, et LSI-kontrollerid kuumenevad tugevalt. Pange t\u00e4hele, et emaplaat ei ulatu praktiliselt kontrollerini, l\u00f5ppedes 3 cm p\u00e4rast PCI-E pesa.<\/p>\n

<\/p>\n

Nagu n\u00e4ete, on k\u00f5ik ventilaatorid \u00fchendatud emaplaadi Supermicro juurde ja re\u017eiimis Optimal<\/strong> \"puhuvad\" s\u00f5ltuvalt sellel olevatest sensoritest, CPU temperatuurist.<\/p>\n

<\/p>\n

Selles platvormis on Xeon E-2236 \u2014 \u00fcsna jahe CPU, mis kliendil, n\u00e4ib, et ei ole tugevalt kuumeneda suutnud.<\/p>\n

<\/p>\n

Andmesenter, kus see server asub, on v\u00e4ga k\u00fclm \u2014 k\u00fclm koridor annab 18\u201320 kraadi.<\/p>\n

<\/p>\n

Need tegurid on viinud v\u00e4ga huvitava n\u00e4htuseni \u2014 RAID-kontrolleri \u00fclekuumenemine.<\/p>\n

<\/p>\n

T\u00f5en\u00e4oline ahel, kuidas see juhtus<\/h3>\n

<\/p>\n

    \n
  1. k\u00fclmprotsessor ja emaplaat teatasid ventilaatoritele, et nad saavad t\u00f6\u00f6tada madalal kiirusel.<\/li>\n
  2. emaplaati RAID-i all ei olnud ja puudusid sensorid, mis fikseerisid \u00fclekuumenemist.<\/li>\n
  3. Ventilaatorid, olles konfigureeritud, t\u00f6\u00f6tasid Optimal re\u017eiimis madalal, vastavalt emaplaadi ja CPU vajadustele.<\/li>\n
  4. Kontroller, saamata piisavalt \u00f5huvoogu, kuumenes \u00fcle.<\/li>\n<\/ol>\n

    <\/p>\n

    Mida me tegime<\/h3>\n

    <\/p>\n

    L\u00fclitasime jahutusventilaatorid \"Standard\" re\u017eiimi, vajadusel viime need k\u00f5rgema j\u00f5udluse re\u017eiimi.<\/p>\n

    <\/p>\n

    J\u00e4reldused<\/h3>\n

    <\/p>\n

    T\u00f5en\u00e4oliselt, kui andmesiiru k\u00fclm koridor ei oleks nii k\u00fclm v\u00f5i kui klient oleks intensiivselt kasutanud CPU-d, ei oleks see probleem v\u00f5ib-olla juhtunud, kuna ventilaatorid oleksid t\u00f6\u00f6tanud intensiivsemalt.<\/p>\n

    <\/p>\n

    Otsustasime endale, et peame ventilaatorite t\u00f6\u00f6re\u017eiimi kindlasti muutma serverites<\/a> RAID-i Optimal re\u017eiimist k\u00f5rgema p\u00f6\u00f6rdemomendi re\u017eiimile.<\/p>\n
