\nPisici \u00een Data Center. Cine este de acord? <\/i><\/p>\n

Crede\u021bi c\u0103 \u00een centrele de date moderne exist\u0103 perne? R\u0103spunsul este: da, \u0219i multe! \u0218i nu sunt folosite pentru ca inginerii \u0219i tehnicienii obosi\u021bi sau chiar pisica (de\u0219i, de unde ar veni o pisic\u0103 \u00een Data Center, nu-i a\u0219a?) s\u0103 poat\u0103 trage un pui de somn. Aceste perne contribuie la siguran\u021ba \u00eempotriva incendiilor \u00een cl\u0103dire. Cloud4Y explic\u0103 de ce.<\/i> <\/a><\/noindex><\/p>\n

Fiecare Data Center este construit av\u00e2nd \u00een vedere asigurarea unei securit\u0103\u021bi maxime pentru echipamente \u0219i datele stocate. Informa\u021biile trebuie s\u0103 fie accesibile clien\u021bilor, indiferent de ceea ce se \u00eent\u00e2mpl\u0103 \u00een interiorul centrului de date. De aceea, \u00eenc\u0103 din etapa de proiectare, se acord\u0103 mult timp cre\u0103rii unor m\u0103suri de securitate \u0219i de stingere a incendiilor fiabile. Ideal, totul \u00een Data Center ar trebui s\u0103 fie rezistent la foc. Astfel, u\u0219ile, pere\u021bii, podeaua \u0219i tavanul sunt fabricate din materiale ignifuge. Teoretic, acestea ar trebui s\u0103 \u00eempiedice r\u0103sp\u00e2ndirea incendiului din camera \u00een care a avut loc aprinderea.<\/p>\n

\u00cen practic\u0103 \u2013 nu. \u0218i totul din cauza echipamentului de re\u021bea \u0219i a cablurilor. Zeci de kilometri de cablu care transport\u0103 curent conecteaz\u0103 tot felul de echipamente. \u0218i cum se trage cablul? Prin canale de cablu care trec prin g\u0103uri mari \u00een podea \u0219i pere\u021bi. \u0218i cum sunt aceste g\u0103uri, exist\u0103 \u0219i o cale de acces pentru foc.<\/p>\n

Da, este imposibil s\u0103 le \u00eenchidem eficient cu mortar de beton sau alte materiale ignifuge grele. Aceste magistrale de cablu pot fi \u00een mod constant extinse cu cabluri noi. \u0218i dac\u0103 umpli g\u0103urile cu beton, ulterior va trebui s\u0103 deschizi totul \u00eenapoi cu viteza fulgerului. Aceasta este o pierdere de timp, costuri financiare suplimentare \u0219i un mare risc ca cineva s\u0103 taie accidental un cablu extrem de important. \u0218i, din p\u0103cate, exact a\u0219a se va \u00eent\u00e2mpla, dovedit.<\/p>\n

Exist\u0103, de asemenea, chituri ignifuge \u0219i panouri compozite (care sunt numite uneori foi). Acestea sunt eficiente, dar tot necesit\u0103 eforturi suplimentare la montare \u0219i demontare.<\/p>\n

A\u0219a c\u0103 este mult mai eficient s\u0103 folosim alte materiale ignifuge, care pot fi transportate u\u0219or, schimbate rapid \u0219i reposate. Acestea au fost transformate \u00een perne ignifuge expandabile.<\/p>\n

\nPernele rezistente la foc pentru centre de date sunt mici c\u0103r\u0103mizi u\u0219oare, care pot fi folosite pentru a acoperi conductele, \u00eenchiz\u00e2nd complet orificiile. A\u0219ez\u00e2ndu-le str\u00e2ns \u00eentre cabluri \u0219i perete, se poate ob\u021bine o bun\u0103 rezisten\u021b\u0103 la incendiu. Secretul const\u0103 \u00een faptul c\u0103 pernele se expand\u0103 \u00een timpul incendiului, dep\u0103\u0219ind de c\u00e2teva ori volumul ini\u021bial. Astfel, se realizeaz\u0103 o etan\u0219are eficient\u0103 \u00een jurul trecerilor inginere\u0219ti. Pernele rezistente la foc pot rezista timp de p\u00e2n\u0103 la 4 ore. Acesta este un timp considerabil. \u00cen 4 ore, sistemul de ap\u0103rare \u00eempotriva incendiilor al centrului de date ar trebui s\u0103 fac\u0103 fa\u021b\u0103 oric\u0103rei fl\u0103c\u0103ri.<\/p>\n

Avantajul acestor perne este c\u0103 ofer\u0103 o solu\u021bie uscat\u0103, curat\u0103 \u0219i u\u0219or de instalat. Aceasta este un factor decisiv pentru un obiect at\u00e2t de important precum un centru de date. \u00cen plus, av\u00e2nd \u00een vedere c\u0103 echipamentele din centrele de date sunt modernizate regulat, posibilitatea de a trece rapid cabluri suplimentare prin perete, f\u0103r\u0103 a-l distruge aproape complet, este foarte apreciat\u0103. A\u0219adar, f\u0103r\u0103 perne, \u00een centrul de date nu se poate.<\/p>\n
