Minul\u00fd t\u00fdden n\u00e1m p\u0159ivezli dieselagreg\u00e1t pro z\u00e1lohovan\u00e9 nap\u00e1jen\u00ed na\u0161eho datacentra. Jedn\u00e1 se zat\u00edm o stroj s men\u0161\u00edm v\u00fdkonem 220 kVA, kter\u00fd v\u0161ak pokryje pot\u0159eby cca 1500 server\u016f.<\/p>\n\n\n\n\n\n\n\n

Jak jsme psali ve \u010dl\u00e1nku\u00a0Jak si vedeme 2 m\u011bs\u00edce od spu\u0161t\u011bn\u00ed slu\u017eeb<\/a>, spu\u0161t\u011bn\u00ed dedikovan\u00fdch server\u016f se oproti pl\u00e1n\u016fm velmi opozdilo. Cel\u00e9 to stoj\u00ed na elekt\u0159in\u011b. Nejv\u011bt\u0161\u00ed probl\u00e9m byl s gener\u00e1torem. Zaprv\u00e9 v \u010cR jsou dieselagreg\u00e1ty z n\u011bjak\u00e9ho d\u016fvodu v\u00fdrazn\u011b dra\u017e\u0161\u00ed ne\u017e v okoln\u00edch zem\u00edch. Zadruh\u00e9 kdy\u017e u\u017e jsme se s jedn\u00edm \u010desk\u00fdm dodavatelem dohodli na zaj\u00edmav\u00e9 cen\u011b a zaj\u00edmav\u00fdch podm\u00ednk\u00e1ch, tak se po objedn\u00e1n\u00ed za\u010daly vyno\u0159ovat n\u011bjak\u00e9 dodatky a dal\u0161\u00ed podm\u00ednky, o kter\u00fdch p\u0159edt\u00edm \u0159e\u010d nebyla, a celkov\u011b s vidinou n\u00e1s jako jist\u00e9ho z\u00e1kazn\u00edka snaha upadla. Tud\u00ed\u017e jsme to rychle ukon\u010dili.<\/p>\n\n\n\n

Nakonec jsme po\u0159\u00eddili gener\u00e1tor v Polsku, kter\u00fd n\u00e1m byl minul\u00fd t\u00fdden p\u0159ivezen a tento nebo p\u0159\u00ed\u0161t\u00ed t\u00fdden bude zapojen. Teprve pot\u00e9 m\u016f\u017ee doj\u00edt ke spu\u0161t\u011bn\u00ed dedikovan\u00fdch server\u016f.

Gener\u00e1tor byl je\u0159\u00e1bem um\u00edst\u011bn na „zahr\u00e1dku“ za na\u0161\u00ed budovou. Nyn\u00ed jen \u010dek\u00e1me na elektrik\u00e1\u0159e, a\u017e p\u0159iprav\u00ed zapojen\u00ed.<\/p>\n\n\n\n
