Dnes sme sa stretli s prehriat\u00edm karty MegaRAID 9361-8i v s\u00favislosti s t\u00fdm, \u017ee platforma nec\u00edtila<\/strong> prehriatie, zatia\u013e \u010do RAID ovl\u00e1da\u010d ho c\u00edtil.<\/strong>.<\/p>\n

Nieko\u013eko d\u00f4le\u017eit\u00fdch bodov, ktor\u00e9 s\u00favisia s t\u00fdmto serverom<\/a> a prostred\u00edm prev\u00e1dzky:<\/p>\n

<\/p>\n

In\u017einier, ktor\u00fd zostavil platformu, \u0161peci\u00e1lne umiestnil pred kartu dva ventil\u00e1tory, preto\u017ee vie, \u017ee LSI ovl\u00e1da\u010de sa ve\u013emi prehrievaj\u00fa. V\u0161imnite si z\u00e1kladn\u00fa dosku, t\u00e1 sa takmer nedost\u00e1va pod ovl\u00e1da\u010d, kon\u010diac 3 cm po slote PCI-E.<\/p>\n

<\/p>\n

Ako vid\u00edte, v\u0161etky ventil\u00e1tory s\u00fa \u0161tandardne pripojen\u00e9 k z\u00e1kladnej doske Supermicro a v re\u017eime Optimal<\/strong> \"f\u00faknu\" v z\u00e1vislosti od senzorov na \u0148om, teploty CPU.<\/p>\n

<\/p>\n

V tejto platforme je nain\u0161talovan\u00fd Xeon E-2236 \u2014 pomerne chladn\u00fd CPU, ktor\u00fd sa klientovi zjavne ani v\u00fdrazne neprehieval.<\/p>\n

<\/p>\n

D\u00e1tov\u00e9 centrum, v ktorom sa nach\u00e1dza tento server, je ve\u013emi chladn\u00e9 \u2014 chladn\u00fd koridor poskytuje 18-20 stup\u0148ov.<\/p>\n

<\/p>\n

Kombin\u00e1cia t\u00fdchto faktorov viedla k ve\u013emi zauj\u00edmav\u00e9mu jav \u2014 prehriatiu RAID ovl\u00e1da\u010da.<\/p>\n

<\/p>\n

Mo\u017en\u00fd sled udalost\u00ed, ako k tomu do\u0161lo,<\/h3>\n

<\/p>\n

    \n
  1. chladn\u00fd procesor a z\u00e1kladn\u00e1 doska informovali ventil\u00e1tory, \u017ee m\u00f4\u017eu slab\u0161ie f\u00faka\u0165.<\/li>\n
  2. Z\u00e1kladn\u00e1 doska pod RAID-om ch\u00fdbala a neexistovali senzory, ktor\u00e9 by zaznamen\u00e1vali prehriatie.<\/li>\n
  3. Ventil\u00e1tory, by\u0165 nakonfigurovan\u00e9, v re\u017eime Optimal f\u00fakali slabo, v s\u00falade s potrebami z\u00e1kladnej dosky a CPU.<\/li>\n
  4. Ovl\u00e1da\u010d, nedost\u00e1vaj\u00fac dostato\u010dn\u00fd pr\u00fad vzduchu, sa prehrial.<\/li>\n<\/ol>\n

    <\/p>\n

    \u010co sme urobili:<\/h3>\n

    <\/p>\n

    Prep\u00ednali sme ventil\u00e1tory do re\u017eimu \"\u0160tandard\", v pr\u00edpade potreby prepneme do vy\u0161\u0161ieho re\u017eimu v\u00fdkonu.<\/p>\n

    <\/p>\n

    Zhrnutie<\/h3>\n

    <\/p>\n

    Pravdepodobne, keby bol chladn\u00fd koridor d\u00e1tov\u00e9ho centra menej chladn\u00fd, alebo by klient intenz\u00edvne vyu\u017e\u00edval CPU, t\u00e1to probl\u00e9m by sa nemusel vyskytn\u00fa\u0165, preto\u017ee ventil\u00e1tory by pracovali v intenz\u00edvnej\u0161om re\u017eime.<\/p>\n

    <\/p>\n

    Pre seba sme sa rozhodli ur\u010dite zmeni\u0165 re\u017eim pr\u00e1ce ventil\u00e1torov na serveroch<\/a> s RAID z Optimal na re\u017eim s vy\u0161\u0161ou rot\u00e1ciou.<\/p>\n
