\nKatter i datasenteret. Hvem er med? <\/i><\/p>\n

Hva tror du, finnes det puter i moderne datasentre? Svaret er ja, og mange av dem! Og de er ikke bare for at slitne ingeni\u00f8rer og teknikere, eller til og med katter (selv om, hvor kommer katten fra i datasenteret, egentlig?). Disse putene bidrar til brannsikkerheten i bygningen. Cloud4Y forklarer hva som skjer.<\/i> <\/a><\/noindex><\/p>\n

Hvert datasenter er bygget med tanke p\u00e5 \u00e5 sikre maksimal sikkerhet for utstyret og de lagrede dataene. Informasjonen m\u00e5 v\u00e6re tilgjengelig for kundene uansett hva som skjer inne i datasenteret. Derfor blir det lagt mye tid tidlig i designfasen p\u00e5 \u00e5 skape en solid sikkerhet og brannslukking. Ideelt sett b\u00f8r alt i datasenteret v\u00e6re brannsikkert. D\u00f8rene, veggene, gulvet og taket er laget av brannsikre materialer. Teoretisk skal de kunne hindre brannens spredning fra rommet der brannen oppsto.<\/p>\n

I praksis \u2013 nei. Alt p\u00e5 grunn av nettverksutstyret og kablene. Dutzener av kilometer med kabler, som leder str\u00f8m, forbinder forskjellige typer utstyr. Og hvordan trekker de kablene? Gjennom kabelkanaler som g\u00e5r gjennom store hull i gulv og vegger. Og siden det finnes hull, finnes det ogs\u00e5 en vei for flammen.<\/p>\n

Ja, det er effektivt umulig \u00e5 tette dem med betong eller annet tungt brannsikkert materiale. Nye kabler kan legges til disse kabelkanalene regelmessig. Og hvis man fyller hullene med betong, m\u00e5 man senere rive alt opp igjen for \u00e5 f\u00e5 det tilbake. Dette er tapt tid, ekstra finansielle kostnader, og det er en stor risiko for at noen ved et uhell kutter en spesielt viktig kabel. Og if\u00f8lge loven om j\u00e6velskap skjer akkurat det, det er bevist.<\/p>\n

Det finnes ogs\u00e5 brannsikre fugemasser og komposittplater (noen ganger kalt ark). De er ogs\u00e5 effektive, men krever fortsatt ekstra innsats ved montering og demontering.<\/p>\n

S\u00e5 det er mye mer effektivt \u00e5 bruke andre brannsikre materialer, som er lette \u00e5 transportere, raskt skifte ut og omplassere. Disse er blitt til brannhemmende puter.<\/p>\n

\nDenne puten laget av finmasket, tett og mekanisk sterk glassfiber med spesialfyll kan lagres p\u00e5 lager (t\u00f8rt og varmt) i ubegrenset tid inntil den trengs. Den inneholder ikke mineralfiber, er motstandsdyktig mot atmosf\u00e6risk korrosjon og fuktighet. Noen produsenter garanterer at putene deres kan vare i lang tid i fuktige, d\u00e5rlig ventilerte rom.<\/p>\n

\nBrannbestandige puter for datasentre er sm\u00e5, lette blokker som er praktiske for \u00e5 omgi hovedledninger ved \u00e5 helt dekke \u00e5pningene. Ved \u00e5 plassere dem tett mellom kablene og veggen, kan man oppn\u00e5 god brannmotstand. Hemmeligheten er at putene utvider seg ved brann, mange ganger i volum sammenlignet med den opprinnelige st\u00f8rrelsen. Dermed oppn\u00e5s en effektiv tetning rundt tekniske gjennomf\u00f8ringer. Brannbestandige puter kan motst\u00e5 brann i opptil 4 timer. Det er mye. Innen 4 timer m\u00e5 brannslukkingssystemet i datasenteret h\u00e5ndtere enhver brann.<\/p>\n

Fordelen med slike puter er at de tilbyr en t\u00f8rr, ren og enkel l\u00f8sning for installasjon. Dette er en avgj\u00f8rende faktor for en s\u00e5 viktig enhet som et datasenter. I tillegg, siden utstyret i datasentre jevnlig oppgraderes, verdsettes muligheten for raskt \u00e5 dra ekstra kabler gjennom veggen uten \u00e5 \u00f8delegge den altfor mye, sv\u00e6rt h\u00f8yt. S\u00e5 uten puter er datasenteret umulig.<\/p>\n
