V p\u016flce \u00fanora jsme psali<\/a> o pokroku ve v\u00fdvoji na\u0161eho olejov\u00e9ho chlazen\u00ed, konkr\u00e9tn\u011b o olejov\u00e9 van\u011b nejnov\u011bj\u0161\u00ed verze v4.3, kter\u00e1 se stala prototypem pro ostr\u00e9 testov\u00e1n\u00ed.

Olejovou vanu v4.3 u\u017e n\u00e1m dokon\u010dili ve specializovan\u00e9 v\u00fdrobn\u00ed hale. Jak jsme psali nakonec se konstrukce musela upravit vzhledem k dostupn\u00fdm materi\u00e1l\u016fm a pou\u017eit\u00fdm technologi\u00edm. Vana pojme jen dv\u011b serverov\u00e9 sk\u0159\u00edn\u011b HPE Moonshot (dohromady 90 server\u016f) m\u00edsto p\u016fvodn\u00edch \u010dty\u0159ech (dohromady 180 server\u016f).<\/p>\n

Aby bylo mo\u017en\u00e9 pou\u017e\u00edt \u010dty\u0159i, tak bychom vanu museli nechat vyrobit na zak\u00e1zku n\u011bkde v zahrani\u010d\u00ed na jin\u00fdch technologi\u00edch a nechat si vyrobit i speci\u00e1ln\u00ed plech. Bylo by nutn\u00e9 tak\u00e9 pos\u00edlit konstrukci, co\u017e by v\u00fdznamn\u011b nav\u00fd\u0161ilo cenu a hmotnost.<\/p>\n

Pro n\u00e1s men\u0161\u00ed vany naopak nejsou probl\u00e9m. Z hlediska provozu to nen\u00ed komplikace a bude to m\u00edt i v\u00fdhody v rozlo\u017een\u00ed rizik.<\/p>\n

Prototyp u\u017e je v DC2<\/h3>\n

Prototyp olejov\u00e9 vany, kde pob\u011b\u017e\u00ed ostr\u00e9 testy olejov\u00e9ho chlazen\u00ed, u\u017e stoj\u00ed na reg\u00e1le v na\u0161em druh\u00e9m datacentru a toto jsou prvn\u00ed rychle fotky…<\/p>\n

Vana je z nerezov\u00e9ho plechu, st\u011bny jsou t\u0159\u00edpl\u00e1\u0161\u0165ov\u00e9 (jsou tam 2 odd\u011blen\u00e9 a nez\u00e1visl\u00e9 okruhy chlazen\u00ed). Vy\u0161\u0161\u00ed bezpe\u010dnost, vy\u0161\u0161\u00ed spolehlivost.<\/p>\n

\"\"<\/a><\/p>\n

Na fotce nevypad\u00e1 tak velk\u00e1, tak\u017ee p\u0159id\u00e1me je\u0161t\u011b dva kolegy, a\u0165 si ud\u011bl\u00e1te p\u0159edstavu.<\/p>\n

Na zadn\u00ed stran\u011b se nach\u00e1z\u00ed pr\u016fchodky na kabel\u00e1\u017e. Ty mus\u00ed m\u00edt n\u011bkolik d\u016fle\u017eit\u00fdch vlastnost\u00ed, mezi kter\u00e9 pat\u0159\u00ed i odolnost proti vzl\u00ednavosti oleje.<\/p>\n

Ve van\u011b tedy bude olej a v oleji budou plavat servery. Ji\u017e brzo.<\/p>\n

\"\"<\/a><\/p>\n

D\u00edky nov\u00e9mu konceptu chlazen\u00ed nebude pot\u0159eba \u017eebrov\u00e1n\u00ed pro chlazen\u00ed oleje vodou. Oba chlad\u00edc\u00ed okruhy maj\u00ed p\u0159\u00edvod i vypus\u0165\u00a0 na spodn\u00ed stran\u011b vany. Dva chlad\u00edc\u00ed okruhy tam jsou z d\u016fvodu redundance a v\u011bt\u0161\u00ed odolnosti proti poruch\u00e1m.\u00a0 Oba okruhy jsme mohli spojit v jeden, ale rozhodli jsme se pro n\u00e1ro\u010dn\u011bj\u0161\u00ed \u0159e\u0161en\u00ed, kter\u00e9 do budoucna p\u0159inese n\u011bkolik dal\u0161\u00edch v\u00fdhod.<\/p>\n

\"\"<\/a><\/p>\n

Jak se uk\u00e1zalo, tak olejov\u00e9 vany jsou zevnit\u0159 velice prostorn\u00e9 a dokonce i pohodln\u00e9.\u00a0<\/p>\n

\"\"<\/a><\/p>\n

Jen pro zaj\u00edmavost. Nosnost jednoho reg\u00e1lu, kter\u00fd je pro 12 podobn\u00fdch van je 8.520 kg. Ka\u017ed\u00e1 vana m\u016f\u017ee v\u00e1\u017eit a\u017e 710 kg.
