\"Kas
\nAndmed keskuses. Kes on selle poolt? <\/i><\/p>\n

Kuidas arvate, kas t\u00e4nap\u00e4eva andmekeskuses on padjad? Vastame: jah, ja palju! Need ei ole sugugi selleks, et v\u00e4sinud insenerid ja tehnikud v\u00f5i isegi kass (kuigi kust v\u00f5iks andmekeskuses kass olla?) saaksid neile tukkuma j\u00e4\u00e4da. Need padjad on vajalikud hoone tuleohutuse tagamiseks. Cloud4Y selgitab, millest on juttu.<\/i> <\/a><\/noindex><\/p>\n

Iga andmekeskus ehitatakse, et tagada seadmete ja salvestatud andmete maksimaalne turvalisus. Informatsioon peab olema klientidele kergesti ligip\u00e4\u00e4setav, s\u00f5ltumata sellest, mis andmekeskuses toimub. Seet\u00f5ttu p\u00f6\u00f6ratakse juba kavandamisetapis palju aega usaldusv\u00e4\u00e4rse turvalisuse ja tulekustutuse loomisele. Ideaalis peaks andmekeskuses olema k\u00f5ik tulekindel. Seet\u00f5ttu on uksed, seinad, p\u00f5rand ja lagi valmistatud tulekindlatest materjalidest. Teoreetiliselt suudavad need takistada tule levikut ruumi, kus tulekahju on toimunud.<\/p>\n

Praktikas \u2013 ei. Ja k\u00f5ik t\u00e4nu v\u00f5rguseadmetele ja kaablitele. K\u00fcmneid kilomeetreid kaablit, mille kaudu voolab elekter, \u00fchendavad erinevaid seadmeid. Kuidas neid kaableid vedada? Kaablikanalite kaudu, mis l\u00e4bivad suuri auke p\u00f5randas ja seintes. Kui on augud, eksisteerib ka tuleohtudele tee.<\/p>\n

Jah, neid on efektiivselt suletud betoonisegude v\u00f5i muude raskete tulekindlate materjalidega. Neid kaabelmagistraale v\u00f5ivad pidevalt uusi kaableid lisada. Kui valada auk betooniga, tuleb see hiljem kiiresti tagasi l\u00f5hkuda. See on raisatud aeg, lisakulud ja suur risk, et keegi l\u00f5ikab kogemata l\u00e4bi eriti olulise kaabli. Ja seaduse j\u00e4rgi juhtub alati just nii, see on kontrollitud.<\/p>\n

On veel tulekindlaid pahtlid ja komposiitpaneelid (lehed, nagu neid m\u00f5nikord nimetatakse). Need on samuti t\u00f5husad, kuid n\u00f5uavad siiski lisaprotsesse paigaldamisel ja demonteerimisel.<\/p>\n

Seep\u00e4rast on palju t\u00f5husam kasutada teisi tulekindlaid materjale, mida saab lihtsalt transportida, kiiresti vahetada ja \u00fcmber paigutada. Need on paisuvad tulekindlad padjad.<\/p>\n

\nSelline padi, mis on valmistatud peenetapilisest, tihedast ja mehaaniliselt tugevast klaaskangast spetsiaalse t\u00e4iteainega, v\u00f5ib piiramatult kaua ladustada (kuivas ja soojas kohas), kuni seda vajatakse. See ei sisalda mineraalkiude, on vastupidav atmosf\u00e4\u00e4ri korrosioonile ja niiskuse m\u00f5jule. M\u00f5ned tootjad garanteerivad, et nende padi suudab pikka aega vastu pidada niisketes ventileerimata ruumides.<\/p>\n

\nTulekindlad padjad andmekeskustes on v\u00e4ikesed, kergekaalulised telliskivid, millega on mugav kaabeldus t\u00e4ielikult sulgeda. Paigutades need tihedalt kaablite ja seina vahele, saavutatakse hea tulekindlus. Saladus peitub selles, et p\u00e4\u00e4smed suurenevad tulekahju korral mitme korra v\u00f5rra. Nii saavutatakse t\u00f5hus tihend insenerikommunikatsioonide \u00fcmber. Tulekindlad padjad suudavad vastu pidada tulele kuni 4 tundi. See on palju. Nelja tunni jooksul peab andmekeskuse tuleohutuss\u00fcsteem suudma igasuguste tulekahjude vastu toime tulla.<\/p>\n

Nende padjade eelis on see, et need pakuvad kuiva, puhast ja lihtsalt paigaldatavat lahendust. See on kriitilise t\u00e4htsusega tegur sellise olulise objekti nagu andmekeskus jaoks. Lisaks, kuna andmekeskuse seadmeid uuendatakse regulaarselt, on v\u00f5imalus kiiresti lisakaableid l\u00e4bi seina tuua, mitte seinu praktiliselt t\u00e4ielikult l\u00f5hkuda, v\u00e4ga hinnatud. Seega ei saa andmekeskustes ilma padjadeta kuidagi hakkama.<\/p>\n
