\nOdolnos\u0165 DPC 'Tu\u0161ino' zodpoved\u00e1 \u00farovni Tier II. V podstate to znamen\u00e1, \u017ee d\u00e1tov\u00e9 centrum sa nach\u00e1dza v norm\u00e1lne pripraven\u00fdch priestoroch, s\u00fa pou\u017eit\u00e9 z\u00e1lo\u017en\u00e9 zdroje nap\u00e1jania a s\u00fa k dispoz\u00edcii redundatn\u00e9 syst\u00e9mov\u00e9 zdroje. <\/p>\n

Av\u0161ak, v opa\u010dnom pr\u00edpade ako je roz\u0161\u00edren\u00e9 myln\u00e9 predstavenie, \u00farovne Tier necharakterizuj\u00fa 'skvelos\u0165' DPC, ale stupe\u0148 jeho s\u00faladu s aktu\u00e1lnymi obchodn\u00fdmi \u00falohami. A medzi nimi sa nach\u00e1dza mno\u017estvo tak\u00fdch, pre ktor\u00e9 vysok\u00e1 odolnos\u0165 nie je d\u00f4le\u017eit\u00e1, alebo nie je tak d\u00f4le\u017eit\u00e1, aby za \u0148u zaplatili 20-25 tis\u00edc rub\u013eov ro\u010dne, \u010do m\u00f4\u017ee by\u0165 v podmienkach kr\u00edzy pre z\u00e1kazn\u00edka ve\u013emi bolestiv\u00e9.<\/p>\n

Odkia\u013e sa vzala tak\u00e1 suma? Presne ona predstavuje rozdiel medzi cenami za umiestnenie inform\u00e1ci\u00ed v d\u00e1tov\u00fdch centr\u00e1ch<\/a> \u00farovniach Tier II a Tier III v prepo\u010dte na jeden server. \u010c\u00edm viac d\u00e1t, t\u00fdm vidite\u013enej\u0161ia potenci\u00e1lna \u00faspora.<\/p>\n

Ak\u00e9 \u00falohy sa myslia? Napr\u00edklad, uchov\u00e1vanie z\u00e1lo\u017en\u00fdch k\u00f3pi\u00ed alebo \u0165a\u017eba kryptomien. V t\u00fdchto pr\u00edpadoch jednoduch\u00e9 servera<\/a>, pr\u00edpustn\u00e9 Tier II, vyjde lacnej\u0161ie ako Tier III.<\/p>\n

Praxe ukazuje, \u017ee vo v\u00e4\u010d\u0161ine pr\u00edpadov je \u00faspora d\u00f4le\u017eitej\u0161ia ako zv\u00fd\u0161en\u00e1 odolnos\u0165. V Moskve funguje len p\u00e4\u0165 DPC certifikovan\u00fdch pod\u013ea Tier III. A \u00faplne certifikovan\u00fdch pod\u013ea Tier IV nie je v\u00f4bec. <\/p>\n

Ako je usporiadan\u00fd syst\u00e9m nap\u00e1jania DPC 'Tu\u0161ino'?<\/h3>\n

\nPo\u017eiadavky na syst\u00e9m elektrick\u00e9ho z\u00e1sobovania d\u00e1tov\u00e9ho centra \u201eTu\u0161ino\u201c zodpovedaj\u00fa podmienkam \u00farovne Tier II. Ide o redundantn\u00e9 nap\u00e1jacie linky pod\u013ea sch\u00e9my N+1, redundanciu zdrojov bezpreru\u0161en\u00e9ho nap\u00e1jania pod\u013ea sch\u00e9my N+1 a rezerv\u00e1ciu diesel-gener\u00e1torovej stanice pod\u013ea sch\u00e9my N. N+1 v tomto pr\u00edpade znamen\u00e1 sch\u00e9mu s jedn\u00fdm rezervn\u00fdm prvkom, ktor\u00fd zost\u00e1va nevyu\u017eit\u00fd, pokia\u013e v syst\u00e9me ned\u00f4jde k poruche jedn\u00e9ho z hlavn\u00fdch prvkov, a N \u2014 sch\u00e9mu bez rezerv\u00e1cie, pri ktorej porucha ak\u00e9hoko\u013evek prvku vedie k zastaveniu celej s\u00fastavy.<\/p>\n

R\u00f4zne probl\u00e9my spojen\u00e9 s energetick\u00fdm z\u00e1sobovan\u00edm sa rie\u0161ia spr\u00e1vnou vo\u013ebou umiestnenia d\u00e1tov\u00e9ho centra. D\u00e1tov\u00e9 centrum \u201eTu\u0161ino\u201c sa nach\u00e1dza na \u00fazem\u00ed podniku, kam u\u017e prich\u00e1dzaj\u00fa dve linky 110 kV z r\u00f4znych mestsk\u00fdch elektr\u00e1rn\u00ed. Na zariaden\u00ed samotn\u00e9ho z\u00e1vodu je vysok\u00e9 nap\u00e4tie transformovan\u00e9 na stredn\u00e9, pri\u010dom na vstup d\u00e1tov\u00e9ho centra prich\u00e1dzaj\u00fa dve nez\u00e1visl\u00e9 linky 10 kV. <\/p>\n

Transform\u00e1torov\u00e1 stanica vo vn\u00fatri budovy d\u00e1tov\u00e9ho centra transformuje stredn\u00e9 nap\u00e4tie na spotrebite\u013esk\u00e9 240-400 V. V\u0161etky linky s\u00fa veden\u00e9 paralelne, tak\u017ee zariadenia d\u00e1tov\u00e9ho centra z\u00edskavaj\u00fa energiu z dvoch nez\u00e1visl\u00fdch vonkaj\u0161\u00edch zdrojov.<\/p>\n

N\u00edzke nap\u00e4tie z transform\u00e1torov\u00fdch stan\u00edc je priveden\u00e9 na automaty na zavedenie rezervy, ktor\u00e9 zabezpe\u010duj\u00fa prechod medzi mestsk\u00fdmi sie\u0165ami. Na automatick\u00fdch prepojovac\u00edch rel\u00e9 (A\u0412P) in\u0161talovan\u00e9 motorov\u00e9 pohony vy\u017eaduj\u00fa na t\u00fato oper\u00e1ciu 1,2 sekundy. Po\u010das cel\u00e9ho tohto \u010dasu sa z\u00e1\u0165a\u017e pren\u00e1\u0161a na zdroje bezpreru\u0161en\u00e9ho nap\u00e1jania.<\/p>\n

Samostatn\u00e9 A\u0412P je zodpovedn\u00e9 za automatick\u00e9 zapnutie diesel-gener\u00e1tora v pr\u00edpade, \u017ee nap\u00e1janie zlyh\u00e1 na oboch link\u00e1ch. Spustenie diesel-gener\u00e1tora \u2014 proces nie je r\u00fdchly a trv\u00e1 pribli\u017ene 40 sek\u00fand, po\u010das ktor\u00fdch sa elektrick\u00e9 z\u00e1sobovanie \u00faplne pren\u00e1\u0161a na bat\u00e9rie UPS. <\/p>\n

Na plnej n\u00e1dr\u017ei dieselgener\u00e1tor zabezpe\u010duje prev\u00e1dzku d\u00e1tov\u00e9ho centra po dobu 8 hod\u00edn. Zoh\u013ead\u0148uj\u00fac to, d\u00e1tov\u00e9 centrum uzavrelo dve zmluvy s nez\u00e1visl\u00fdmi dod\u00e1vate\u013emi dieselov\u00e9ho paliva, ktor\u00ed sa zaviazali doviez\u0165 nov\u00fa d\u00e1vku paliva do 4 hod\u00edn po v\u00fdzve. Pravdepodobnos\u0165, \u017ee sa u oboch dod\u00e1vate\u013eov vyskytn\u00fa nejak\u00e9 mimoriadne okolnosti, je extr\u00e9mne n\u00edzka. T\u00fdm p\u00e1dom m\u00f4\u017ee samostatnos\u0165 trva\u0165 tak dlho, ako je potrebn\u00e9 oprav\u00e1rensk\u00fdm t\u00edmom na obnovenie nap\u00e1jania aspo\u0148 z jednej z mestsk\u00fdch siet\u00ed.<\/p>\n

Ako sa \u013eahko uk\u00e1\u017ee, nie s\u00fa tu \u017eiadne in\u017einierske vyn\u00e1lezy. Je to o to viac dan\u00e9 t\u00fdm, \u017ee pri v\u00fdstavbe in\u017einierskej infra\u0161trukt\u00fary sa pou\u017e\u00edvali hotov\u00e9 moduly, ktor\u00fdch v\u00fdrobcovia sa zameriavaj\u00fa na takzvan\u00e9ho \u201epriemern\u00e9ho u\u017e\u00edvate\u013ea\u201c.<\/p>\n

Nezvratne, ka\u017ed\u00fd IT \u0161pecialista povie, \u017ee priemernos\u0165 je \u201eani ryba, ani m\u00e4so\u201c a navrhne vyvin\u00fa\u0165 jedine\u010dn\u00fa sadu komponentov pre konkr\u00e9tny syst\u00e9m. Av\u0161ak, t\u00ed, ktor\u00ed s\u00fa ochotn\u00ed za to plati\u0165, zjavne netvoria dlh\u00e9 rady. Preto by sme mali by\u0165 realistami. V praxi to bude vyzera\u0165 takto: n\u00e1kup hotov\u00e9ho vybavenia a zostavenie syst\u00e9mu, ktor\u00fd bude rie\u0161i\u0165 aktu\u00e1lne obchodn\u00e9 \u00falohy. T\u00fdch, ktor\u00ed nes\u00fahlasia s t\u00fdmto pr\u00edstupom, r\u00fdchlo vr\u00e1ti na zem hlavn\u00fd finan\u010dn\u00fd riadite\u013e podniku.<\/p>\n

Ako sa \u013eahko uk\u00e1\u017ee, po\u010det \u201evstupn\u00fdch\u201c a \u201ez\u00e1\u0165a\u017eov\u00fdch\u201c panelov sa nezhoduje \u2014 druh\u00fdch je takmer dvakr\u00e1t menej. To sa stalo mo\u017en\u00e9 preto, \u017ee projektanti infra\u0161trukt\u00fary d\u00e1tov\u00e9ho centra sa rozhodli pou\u017e\u00edva\u0165 ve\u013ek\u00e9 panely, aby mohli pripoji\u0165 tri a viac prich\u00e1dzaj\u00facich l\u00edni\u00ed.

Tak\u017ee niekedy pou\u017eitie v\u00e4\u010d\u0161\u00edch modelov umo\u017e\u0148uje u\u0161etri\u0165 vz\u00e1cny priestor. Len preto, \u017ee ve\u013ek\u00fdch panelov bude potrebn\u00e9 menej. <\/p>\n
