\nMa\u010dke u podatkovnom centru. Tko je za? <\/i><\/p>\n

\u0160to mislite, ima li u modernom podatkovnom centru jastu\u010di\u0107a? Odgovaramo: da, i to mno\u0161tvo! I nisu potrebni samo da bi se umorni in\u017eenjeri i tehni\u010dari ili \u010dak ma\u010dka (iako, otkud ma\u010dka u podatkovnom centru, zapravo?) mogli odmoriti. Ovi jastu\u010di\u0107i odgovaraju za protupo\u017earnu sigurnost zgrade. Cloud4Y obja\u0161njava o \u010demu se radi.<\/i> <\/a><\/noindex><\/p>\n

Svaki podatkovni centar gradi se s obzirom na maksimalnu sigurnost opreme i pohranjenih podataka. Informacije moraju biti dostupne klijentima bez obzira \u0161to se doga\u0111a unutar podatkovnog centra. Stoga se na fazi projektiranja pridaje puno pa\u017enje izradi pouzdane sigurnosti i protupo\u017earne za\u0161tite. U idealnom slu\u010daju, sve u podatkovnom centru trebalo bi biti otporno na vatru. Tako su vrata, zidovi, pod i strop izra\u0111eni od protupo\u017earnih materijala. Teoretski, oni su sposobni sprije\u010diti \u0161irenje vatre iz prostorije gdje je do\u0161lo do po\u017eara.<\/p>\n

U praksi \u2013 nije. A sve zbog mre\u017ene opreme i kabela. Desetci kilometara kabela, kroz koje prolazi struja, povezuju raznu opremu. A kako se prote\u017eu kablovi? Kroz kabelske kanale, koji prolaze kroz velike rupe u podu i zidovima. A ako postoje otvori, postoji i put za vatru.<\/p>\n

Da, u\u010dinkovito ih zatvoriti betonskom smjesom ili drugim te\u0161kim protupo\u017earnim materijalima nije mogu\u0107e. U ove kabelske magistrale redovito se dodaju novi kablovi. I ako se rupa zapuni betonom, poslije \u0107e se morati ubrzano sve iskopati natrag. To je izgubljeno vrijeme, dodatni financijski tro\u0161kovi, kao i veliki rizik da netko slu\u010dajno prere\u017ee posebno va\u017ean kabel. A po zakonu podlosti, upravo \u0107e se to dogoditi, provjereno.<\/p>\n

Tu su jo\u0161 i protupo\u017earne mase i kompozitne plo\u010de (plahte, kako ih ponekad nazivaju). Tako\u0111er su u\u010dinkovite, ali svejedno zahtijevaju dodatne napore prilikom monta\u017ee i demonta\u017ee.<\/p>\n

Dakle, mnogo je u\u010dinkovitije koristiti druge protupo\u017ene materijale koji se lako transportiraju, brzo mijenjaju i preure\u0111uju. Postali su to napuhani protupo\u017earni jastu\u010di\u0107i.<\/p>\n

\nProtupo\u017earni jastu\u010di\u0107i za podatkovne centre su mali, laki blokovi kojima je lako oblo\u017eiti kanale, potpuno zatvaraju\u0107i otvore. \u010cvrsto ih postavljaju\u0107i izme\u0111u kablova i zida, mo\u017ee se posti\u0107i dobra otpornost na vatru. Tajna je u tome \u0161to se jastu\u010di\u0107i u slu\u010daju po\u017eara pove\u0107avaju, nekoliko puta prema\u0161uju\u0107i prvobitni volumen. Tako se posti\u017ee efikasno zaptivanje oko in\u017eenjerskih prolaza. Protupo\u017earni jastu\u010di\u0107i mogu izdr\u017eati vatru do 4 sata. To je puno. Za 4 sata, protupo\u017earni sistem podatkovnog centra mora se nositi s bilo kojim po\u017earom.<\/p>\n

Prednost takvih jastu\u010di\u0107a je u tome \u0161to nude suvo, \u010disto i jednostavno re\u0161enje za instalaciju. A to je presudan faktor za tako va\u017ean objekat kao \u0161to je podatkovni centar. Osim toga, budu\u0107i da se oprema u podatkovnom centru redovno modernizuje, mogu\u0107nost brzog prolaska dodatnih kablova kroz zid, ne uni\u0161tavaju\u0107i ga gotovo potpuno, veoma je cenjena. Tako da bez jastu\u010di\u0107a u podatkovnom centru nikako.<\/p>\n
