TL;DR;<\/strong> Ustawienie trybu pracy uk\u0142adu ch\u0142odzenia serwera Supermicro Optimal nie zapewnia stabilno\u015bci pracy kontrolera LSI MegaRAID 9361-8i w zimnym centrum danych.<\/p>\n

<\/p>\n

Staramy si\u0119 nie u\u017cywa\u0107 sprz\u0119towych kontroler\u00f3w RAID, ale mamy jednego klienta, kt\u00f3ry preferuje konfiguracje z LSI MegaRAID. Dzi\u015b napotkali\u015bmy problem przegrzewania karty MegaRAID 9361-8i w zwi\u0105zku z tym, \u017ce platforma nie odczuwa\u0142a<\/strong> przegrzania, a kontroler RAID odczuwa\u0142<\/strong>.<\/p>\n

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

Widok platformy z kart\u0105 RAID przedstawiono na poni\u017cszych rysunkach:<\/p>\n

<\/p>\n

<\/p>\n

\"Kr\u00f3tka<\/p>\n

<\/p>\n

Kilka istotnych kwestii zwi\u0105zanych z tym serwerem<\/a> i \u015brodowiskiem eksploatacyjnym:<\/p>\n

<\/p>\n

In\u017cynier, kt\u00f3ry zmontowa\u0142 platform\u0119, specjalnie umie\u015bci\u0142 naprzeciwko karty dwa wentylatory, poniewa\u017c wie, \u017ce kontrolery LSI mocno si\u0119 nagrzewaj\u0105. Zwr\u00f3\u0107 uwag\u0119 na p\u0142yt\u0119 g\u0142\u00f3wn\u0105, praktycznie nie wchodzi pod kontroler, ko\u0144cz\u0105c si\u0119 3 cm za slotem PCI-E.<\/p>\n

<\/p>\n

Jak wida\u0107, wszystkie wentylatory s\u0105 prawid\u0142owo pod\u0142\u0105czone do p\u0142yty g\u0142\u00f3wnej Supermicro i w trybie Optimal<\/strong> "wieje" w zale\u017cno\u015bci od czujnik\u00f3w na nim, temperatury CPU.<\/p>\n

<\/p>\n

W tej platformie znajduje si\u0119 procesor Xeon E-2236 \u2014 do\u015b\u0107 ch\u0142odny CPU, kt\u00f3ry u klienta, najprawdopodobniej, nie nagrzewa\u0142 si\u0119 zbytnio.<\/p>\n

<\/p>\n

Centrum danych, w kt\u00f3rym znajduje si\u0119 ten serwer, jest do\u015b\u0107 zimne \u2014 zimny korytarz daje 18-20 stopni.<\/p>\n

<\/p>\n

Suma tych czynnik\u00f3w prowadzi\u0142a do bardzo interesuj\u0105cego zjawiska \u2014 przegrzania kontrolera RAID.<\/p>\n

<\/p>\n

Prawdopodobny ci\u0105g zdarze\u0144, jak to si\u0119 sta\u0142o<\/h3>\n

<\/p>\n

    \n
  1. zimny procesor i p\u0142yta g\u0142\u00f3wna informowa\u0142y wentylatory, \u017ce mo\u017cna dmucha\u0107 s\u0142abo.<\/li>\n
  2. p\u0142yta g\u0142\u00f3wna pod RAID-em by\u0142a nieobecna i nie by\u0142o czujnik\u00f3w, kt\u00f3re rejestrowa\u0142yby przegrzanie.<\/li>\n
  3. Wentylatory, b\u0119d\u0105c skonfigurowanymi w trybie Optimal, dmucha\u0142y s\u0142abo, zgodnie z potrzebami p\u0142yty g\u0142\u00f3wnej i CPU.<\/li>\n
  4. Kontroler, nie otrzymuj\u0105c wystarczaj\u0105cego przep\u0142ywu powietrza, przegrza\u0142 si\u0119.<\/li>\n<\/ol>\n

    <\/p>\n

    Co zrobili\u015bmy<\/h3>\n

    <\/p>\n

    Prze\u0142\u0105czyli\u015bmy wentylatory w tryb "Standard", w razie potrzeby przestawimy na wy\u017cszy tryb wydajno\u015bci.<\/p>\n

    <\/p>\n

    Wnioski<\/h3>\n

    <\/p>\n

    Prawdopodobnie, gdyby zimny korytarz centrum danych nie by\u0142 tak zimny, lub gdyby klient intensywnie korzysta\u0142 z CPU, ten problem m\u00f3g\u0142by nie wyst\u0105pi\u0107, poniewa\u017c wentylatory dzia\u0142a\u0142yby w bardziej intensywnym trybie.<\/p>\n

    <\/p>\n

    Dla siebie postanowili\u015bmy z pewno\u015bci\u0105 zmieni\u0107 tryb pracy wentylator\u00f3w na serwerach<\/a> z RAID z Optimal na tryb z wy\u017csz\u0105 pr\u0119dko\u015bci\u0105 obrotow\u0105.<\/p>\n
