<\/p>\n

Sna\u017e\u00edme se nepou\u017e\u00edvat hardwarov\u00e9 RAID kontrol\u00e9ry, ale m\u00e1me jednoho klienta, kter\u00fd preferuje konfigurace s LSI MegaRAID. Dnes jsme se setkali s p\u0159eh\u0159\u00e1t\u00edm karty MegaRAID 9361-8i kv\u016fli tomu, \u017ee platforma nec\u00edtila<\/strong> p\u0159eh\u0159\u00e1t\u00ed, zat\u00edmco RAID kontrol\u00e9r to c\u00edtil.<\/strong>.<\/p>\n

N\u011bkolik d\u016fle\u017eit\u00fdch bod\u016f souvisej\u00edc\u00edch s t\u00edmto serverem<\/a> a provozn\u00edm prost\u0159ed\u00edm:<\/p>\n

<\/p>\n

In\u017een\u00fdr, kter\u00fd platformu sestavoval, um\u00edstil proti kart\u011b dva ventil\u00e1tory, proto\u017ee v\u00ed, \u017ee LSI kontrol\u00e9ry se hodn\u011b zah\u0159\u00edvaj\u00ed. V\u0161imn\u011bte si, \u017ee z\u00e1kladn\u00ed deska prakticky \u201enezasahuje\u201c pod kontrol\u00e9r, kon\u010d\u00ed 3 cm po slotu PCI-E.<\/p>\n

<\/p>\n

Jak vid\u00edte, v\u0161echny ventil\u00e1tory jsou p\u0159ipojeny standardn\u011b k z\u00e1kladn\u00ed desce Supermicro a v re\u017eimu Optimal<\/strong> "foukaj\u00ed" v z\u00e1vislosti na senzorech na n\u00ed, teplot\u011b CPU.<\/p>\n

<\/p>\n

Na t\u00e9to platform\u011b je procesor Xeon E-2236 \u2014 velmi chladn\u00fd CPU, kter\u00fd u klienta pravd\u011bpodobn\u011b ani moc nezah\u0159\u00edval.<\/p>\n

<\/p>\n

Datov\u00e9 centrum, ve kter\u00e9m se tento server nach\u00e1z\u00ed, je velmi chladn\u00e9 \u2014 chladn\u00fd koridor poskytuje 18-20 stup\u0148\u016f.<\/p>\n

<\/p>\n

Kombinace t\u011bchto faktor\u016f vedla k velmi zaj\u00edmav\u00e9mu jevu \u2014 p\u0159eh\u0159\u00e1t\u00ed RAID kontrol\u00e9ru.<\/p>\n

<\/p>\n

Pravd\u011bpodobn\u00fd sled, jak k tomu do\u0161lo,<\/h3>\n

<\/p>\n

    \n
  1. chladn\u00fd procesor a z\u00e1kladn\u00ed deska informovaly ventil\u00e1tory, \u017ee mohou slab\u011b foukat.<\/li>\n
  2. Z\u00e1kladn\u00ed deska pod RAIDem chyb\u011bla a nebyly tam senzory, kter\u00e9 by zaznamen\u00e1valy p\u0159eh\u0159\u00e1t\u00ed.<\/li>\n
  3. Ventil\u00e1tory, by\u0165 konfigurovan\u00e9, v re\u017eimu Optimal foukaly slab\u011b, podle pot\u0159eb z\u00e1kladn\u00ed desky a CPU.<\/li>\n
  4. Kontrol\u00e9r, nedost\u00e1vaj\u00edc\u00ed dostate\u010dn\u00fd pr\u016ftok vzduchu, se p\u0159eh\u0159\u00e1l.<\/li>\n<\/ol>\n

    <\/p>\n

    Co jsme ud\u011blali,<\/h3>\n

    <\/p>\n

    P\u0159epnuli jsme ventil\u00e1tory do re\u017eimu "Standard", v p\u0159\u00edpad\u011b pot\u0159eby je p\u0159epneme do vy\u0161\u0161\u00edho v\u00fdkonov\u00e9ho re\u017eimu.<\/p>\n

    <\/p>\n

    Z\u00e1v\u011bry<\/h3>\n

    <\/p>\n

    Pravd\u011bpodobn\u011b, kdyby chladn\u00fd koridor datov\u00e9ho centra nebyl tak chladn\u00fd, nebo kdyby klient intenzivn\u011bji pou\u017e\u00edval CPU, tento probl\u00e9m by se nemusel st\u00e1t, proto\u017ee ventil\u00e1tory by pracovaly v intenzivn\u011bj\u0161\u00edm re\u017eimu.<\/p>\n

    <\/p>\n

    Rozhodli jsme se, \u017ee ur\u010dit\u011b zm\u011bn\u00edme re\u017eim pr\u00e1ce ventil\u00e1tor\u016f na serverech<\/a> s RAID z Optimal na re\u017eim s vy\u0161\u0161\u00ed frekvenc\u00ed ot\u00e1\u010den\u00ed.<\/p>\n
