Tyto pol\u0161t\u00e1\u0159e maj\u00ed na starosti protipo\u017e\u00e1rn\u00ed bezpe\u010dnost budovy. Cloud4Y vysv\u011btluje, co a jak.<\/i> <\/a><\/noindex><\/p>\n

Ka\u017ed\u00e9 datov\u00e9 centrum je navr\u017eeno s ohledem na zaji\u0161t\u011bn\u00ed maxim\u00e1ln\u00ed bezpe\u010dnosti za\u0159\u00edzen\u00ed a uchov\u00e1van\u00fdch dat.

Proto se ji\u017e ve f\u00e1zi n\u00e1vrhu v\u011bnuje mnoho \u010dasu vytvo\u0159en\u00ed spolehliv\u00e9 bezpe\u010dnosti a protipo\u017e\u00e1rn\u00ed ochrany. Ide\u00e1ln\u011b by m\u011blo b\u00fdt v\u0161e v datov\u00e9m centru ohnivzdorn\u00e9. Tak\u017ee dve\u0159e, st\u011bny, podlaha a strop jsou vyrobeny z ohnivzdorn\u00fdch materi\u00e1l\u016f. Teoreticky by m\u011bly zabr\u00e1nit \u0161\u00ed\u0159en\u00ed ohn\u011b z m\u00edstnosti, kde do\u0161lo k po\u017e\u00e1ru.<\/p>\n

V praxi \u2013 ne. A to v\u0161echno kv\u016fli s\u00ed\u0165ov\u00e9mu vybaven\u00ed a kabel\u016fm. Des\u00edtky kilometr\u016f kabel\u016f, kter\u00fdmi proch\u00e1z\u00ed elektrick\u00fd proud, spojuj\u00ed r\u016fzn\u00e9 za\u0159\u00edzen\u00ed. A jak se tahaj\u00ed kabely? Skrze kabelov\u00e9 kan\u00e1ly, kter\u00e9 proch\u00e1zej\u00ed velk\u00fdmi otvory v podlaze a st\u011bn\u00e1ch. A jeliko\u017e jsou zde otvory, existuje tak\u00e9 skulina pro ohe\u0148.<\/p>\n

Ano, efektivn\u011b je uzav\u0159\u00edt pomoc\u00ed betonov\u00e9 sm\u011bsi nebo jin\u00fdch t\u011b\u017ek\u00fdch ohnivzdorn\u00fdch materi\u00e1l\u016f nen\u00ed mo\u017en\u00e9. Do t\u011bchto kabelov\u00fdch trat\u00ed mohou pravideln\u011b p\u0159ib\u00fdvat nov\u00e9 kabely. A pokud d\u016fkladn\u011b zalijete otvor betonem, n\u00e1sledn\u011b budete muset v\u0161e zp\u011bt rozebrat v rychl\u00e9m tempu. To je ztracen\u00fd \u010das, dodate\u010dn\u00e9 finan\u010dn\u00ed n\u00e1klady, a tak\u00e9 velk\u00e9 riziko, \u017ee n\u011bkdo omylem p\u0159e\u0159\u00edzne zvl\u00e1\u0161\u0165 d\u016fle\u017eit\u00fd kabel. A podle z\u00e1kona podlosti se p\u0159esn\u011b tohle stane, ov\u011b\u0159eno.<\/p>\n

Existuj\u00ed tak\u00e9 protipo\u017e\u00e1rn\u00ed tmely a kompozitn\u00ed panely (pl\u00e1ty, jak je n\u011bkdy naz\u00fdvaj\u00ed). Ty jsou tak\u00e9 efektivn\u00ed, ale st\u00e1le vy\u017eaduj\u00ed dal\u0161\u00ed \u00fasil\u00ed p\u0159i mont\u00e1\u017ei a demont\u00e1\u017ei.<\/p>\n
