\nKatter i datacentret. Vem \u00e4r f\u00f6r? <\/i><\/p>\n

Vad tycker ni, finns det kuddar i moderna datacenter? Svaret \u00e4r ja, och m\u00e5nga! De \u00e4r inte bara f\u00f6r att tr\u00f6tta ingenj\u00f6rer och tekniker, eller till och med en katt (\u00e4ven om en katt i datacentret \u00e4r tveksamt, eller?). Dessa kuddar bidrar till brand s\u00e4kerheten i byggnaden. Cloud4Y f\u00f6rklarar vad som g\u00e4ller.<\/i> <\/a><\/noindex><\/p>\n

Varje datacenter byggs med syftet att s\u00e4kerst\u00e4lla maximal s\u00e4kerhet f\u00f6r utrustningen och de lagrade uppgifterna. Informationen m\u00e5ste vara tillg\u00e4nglig f\u00f6r kunderna oavsett vad som h\u00e4nder inom datacentret. D\u00e4rf\u00f6r \u00e4gnas stor tid \u00e5t att skapa tillf\u00f6rlitliga s\u00e4kerhets- och brandskyddsl\u00f6sningar redan under projekteringsfasen. Idealiskt sett borde allt i datacentret vara brands\u00e4kert. S\u00e5 d\u00f6rrar, v\u00e4ggar, golv och tak \u00e4r tillverkade av brandbest\u00e4ndiga material. Teoretiskt sett \u00e4r de kapabel att f\u00f6rhindra spridning av brand fr\u00e5n det rum d\u00e4r en brand utbryter.<\/p>\n

I praktiken \u2013 nej. Och det beror p\u00e5 n\u00e4tverksutrustningen och kablarna. Tio mil kablar som leder elektrisk str\u00f6m f\u00f6renar olika typer av utrustning. Hur drar man kablar? Genom kabelkanaler som passerar genom stora h\u00e5l i golv och v\u00e4ggar. Och finns det h\u00e5l finns det ocks\u00e5 en v\u00e4g f\u00f6r elden.<\/p>\n

Ja, det \u00e4r faktiskt om\u00f6jligt att effektivt st\u00e4nga dem med hj\u00e4lp av betongblandningar eller andra tunga brandbest\u00e4ndiga material. Nya kablar kan regelbundet l\u00e4ggas till i dessa kabelledningar. Och om man fyller h\u00e5let med betong, m\u00e5ste man sedan i k\u00f6r tempo bryta upp allt igen. Det \u00e4r f\u00f6rlorad tid, extra kostnader och en stor risk att n\u00e5gon oavsiktligt sk\u00e4r av en s\u00e4rskilt viktig kabel. Och enligt lagarna om otur, det \u00e4r precis vad som kommer att h\u00e4nda, det \u00e4r bepr\u00f6vat.<\/p>\n

Det finns ocks\u00e5 brandhindrande t\u00e4tningsmedel och kompositpaneler (\u00e4ven kallade ark). De \u00e4r ocks\u00e5 effektiva, men kr\u00e4ver \u00e4nd\u00e5 extra insatser vid installation och demontering.<\/p>\n

S\u00e5 det \u00e4r mycket effektivare att anv\u00e4nda andra brands\u00e4kra material som kan transporteras enkelt, snabbt bytas och omplaceras. Det har blivit sv\u00e4llande brands\u00e4kra kuddar.<\/p>\n

\nDen h\u00e4r kudden \u00e4r tillverkad av finmaskigt, t\u00e4tt och mekaniskt starkt glasfiber med ett speciellt fyllnadsmaterial och kan lagras obegr\u00e4nsat l\u00e4nge p\u00e5 ett lager (torrt och varmt) tills den beh\u00f6vs. Den inneh\u00e5ller inga mineralfibrer, \u00e4r motst\u00e5ndskraftig mot atmosf\u00e4risk korrosion och fukt. Vissa tillverkare garanterar att deras kudde kan h\u00e5lla l\u00e4nge i fuktiga, of\u00f6rsedda lokaler.<\/p>\n

\nEldresistenta kuddar f\u00f6r datacenter \u00e4r sm\u00e5, l\u00e4tta byggstenar som enkelt kan placeras runt ledningarna och helt t\u00e4cka \u00f6ppningarna. Genom att f\u00f6rsiktigt placera dem mellan kablarna och v\u00e4ggen kan man uppn\u00e5 bra brands\u00e4kerhet. Hemligheten ligger i att kuddarna expanderar vid brand, flera g\u00e5nger \u00f6ver deras ursprungliga volym. Detta ger en effektiv t\u00e4tning runt tekniska genomf\u00f6ringar. Eldresistenta kuddar kan motst\u00e5 eld i upp till 4 timmar. Det \u00e4r mycket. Inom 4 timmar m\u00e5ste datacenterets brandbek\u00e4mpningssystem hantera varje brand.<\/p>\n

F\u00f6rdelen med dessa kuddar \u00e4r att de erbjuder en torr, ren och l\u00e4ttinstallerad l\u00f6sning. Detta \u00e4r en avg\u00f6rande faktor f\u00f6r en s\u00e5 viktig anl\u00e4ggning som ett datacenter. Dessutom, eftersom utrustningen i datacenter regelbundet uppgraderas, v\u00e4rderas m\u00f6jligheten att snabbt dra fler kablar genom v\u00e4ggen utan att helt f\u00f6rst\u00f6ra den mycket h\u00f6gt. S\u00e5 utan kuddar g\u00e5r det helt enkelt inte i ett datacenter.<\/p>\n
