TL;DR;<\/strong> Configurarea modului de operare al sistemului de r\u0103cire al serverului Supermicro Optimal nu asigur\u0103 stabilitatea func\u021bion\u0103rii controller-ului LSI MegaRAID 9361-8i \u00een centrul de date rece.<\/p>\n

<\/p>\n

\u00cencerc\u0103m s\u0103 nu folosim controllere hardware RAID, dar avem un client care prefer\u0103 configura\u021bii cu LSI MegaRAID. Ast\u0103zi ne-am confruntat cu supraincalzirea pl\u0103cii MegaRAID 9361-8i din cauza c\u0103 platforma nu sim\u021bea<\/strong> suprainc\u0103lzirea, \u00een timp ce controller-ul RAID o sim\u021bea.<\/strong>.<\/p>\n

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

Aspectul platformei cu placa RAID este prezentat \u00een imaginile de mai jos:<\/p>\n

<\/p>\n

\"A<\/p>\n

<\/p>\n

\"A<\/p>\n

<\/p>\n

C\u00e2teva aspecte importante legate de aceasta serverul<\/a> \u0219i mediul de exploatare:<\/p>\n

<\/p>\n

Inginerul care a asamblat platforma a plasat special dou\u0103 ventilatoare \u00een fa\u021ba pl\u0103cii, \u0219tiind c\u0103 controllerele LSI se \u00eenc\u0103lzesc considerabil. Observa\u021bi placa de baz\u0103; aceasta nu se extinde aproape deloc sub controller, termin\u00e2ndu-se la aproximativ 3 cm dup\u0103 slotul PCI-E.<\/p>\n

<\/p>\n

A\u0219a cum vede\u021bi, toate ventilatoarele sunt conectate corespunz\u0103tor la placa de baz\u0103 Supermicro \u0219i \u00een modul Optimal<\/strong> \"sufl\u0103\" \u00een func\u021bie de senzorii de pe ea, temperatura CPU.<\/p>\n

<\/p>\n

\u00cen aceast\u0103 platform\u0103 se afl\u0103 un Xeon E-2236 \u2013 un CPU destul de rece, care, probabil, nu s-a mai \u00eenc\u0103lzit semnificativ la client.<\/p>\n

<\/p>\n

Centrul de date \u00een care se afl\u0103 acest server este destul de rece \u2013 corridorul rece men\u021bine o temperatur\u0103 de 18-20 de grade.<\/p>\n

<\/p>\n

\u00centreaga combina\u021bie de factori a dus la un fenomen foarte interesant \u2013 suprainc\u0103lzirea controller-ului RAID.<\/p>\n

<\/p>\n

Ciclul probabil, cum s-a \u00eent\u00e2mplat acest lucru<\/h3>\n

<\/p>\n

    \n
  1. CPU-ul rece \u0219i placa de baz\u0103 informau ventilatoarele c\u0103 pot suflat slab.<\/li>\n
  2. Placa de baz\u0103 sub RAID era absent\u0103 \u0219i nu erau senzori care s\u0103 \u00eenregistreze supraincalzirea.<\/li>\n
  3. Ventilatoarele, fiind configurate, \u00een modul Optimal sufla slab, conform cerin\u021belor pl\u0103cii de baz\u0103 \u0219i CPU-ului.<\/li>\n
  4. Controller-ul, neprimind un flux de aer suficient, s-a supraincalzit.<\/li>\n<\/ol>\n

    <\/p>\n

    Ce am f\u0103cut<\/h3>\n

    <\/p>\n

    Am comutat ventilatoarele \u00een modul \"Standard\"; \u00een caz de nevoie, le vom trece \u00eentr-un mod de performan\u021b\u0103 mai ridicat.<\/p>\n

    <\/p>\n

    Conclusions<\/h3>\n

    <\/p>\n

    Cel mai probabil, dac\u0103 corridorul rece al centrului de date nu ar fi fost at\u00e2t de rece sau clientul ar fi utilizat intens CPU-ul, aceast\u0103 problem\u0103 nu ar fi ap\u0103rut, deoarece ventilatoarele ar fi func\u021bionat \u00eentr-un mod mai intens.<\/p>\n

    <\/p>\n

    Pentru noi, am decis cu siguran\u021b\u0103 s\u0103 schimb\u0103m modul de func\u021bionare al ventilatoarelor de servere<\/a> la RAID de la Optimal la un mod cu o frecven\u021b\u0103 de rota\u021bie mai mare.<\/p>\n
