\nKassid andmekeskustes. Kes on n\u00f5us? <\/i><\/p>\n

Kuidas arvate, kas t\u00e4nap\u00e4evases andmekeskuses on padjad? Vastame: jah, ja palju! Ja nad ei ole seal mitte selleks, et v\u00e4sinud insenerid ja tehnikud v\u00f5i isegi kass saaksid sellele j\u00e4\u00e4da uina. (Kuidas kass andmekeskusesse satub, eks ole?) Need padjad vastutavad hoone tuleohutuse eest. Cloud4Y r\u00e4\u00e4gib, mis milleks.<\/i> <\/a><\/noindex><\/p>\n

Iga andmekeskuse ehitus toimub selleks, et tagada seadmete ja salvestatud andmete maksimaalne turvalisus. Informatsioon peab olema klientidele k\u00e4ttesaadav, olgu mis tahes toimub andmekeskuse sees. Seet\u00f5ttu pannakse juba projekteerimisetapis palju t\u00e4helepanu usaldusv\u00e4\u00e4rse turvalisuse ja tulekustutuse loomisele. Ideaalis peaks andmekeskuses k\u00f5ik olema tulekindel. Seega on uksed, seinad, p\u00f5randa ja lae valmistamiseks kasutatud tulekindlaid materjale. Teoreetiliselt suudavad need takistada tule levikut ruumis, kus tulekahju toimus.<\/p>\n

Kuid praktikas \u2013 mitte. K\u00f5ik on seotud v\u00f5rgu seadmete ja kaablitega. K\u00fcmneid kilomeetreid kaablit, mille kaudu vool liigub, \u00fchendavad erinevaid seadmeid. Kuidas kaablit vedada? Kaablikanalite kaudu, mis l\u00e4bivad suuri auke p\u00f5randas ja seintes. Ja kui augud on olemas, siis on ka tule jaoks kaugus.<\/p>\n

Jah, t\u00f5husalt sulgeda neid betoon segu v\u00f5i muu raske tulekindla materjaliga ei ole v\u00f5imalik. Neisse kaabliteedesse v\u00f5ib regulaarselt lisada uusi kaableid. Ja kui auk t\u00e4ita betooniga, tuleb see hiljem kiiresti uuesti lahti raiuda. See on kaotatud aeg, lisakulud ja suur risk, et keegi l\u00f5ikab kogemata l\u00e4bi eriti olulise kaabli. Ja paratamatuse seaduse j\u00e4rgi juhtubki see, see on t\u00f5estatud.<\/p>\n

On veel tuleohutuse t\u00e4iteained ja komposiitpaneelid (mida m\u00f5ned nimetavad lehtedeks). Need on samuti efektiivsed, kuid n\u00f5uavad siiski n\u00f5uavad lisaponnistusi paigaldamise ja demonteerimise korral.<\/p>\n

Seega on palju efektiivsem kasutada muid tulekindlaid materjale, mida saab h\u00f5lpsasti transportida, kiiresti vahetada ja paigaldada. Need on muutunud paisuvas tulekindlatesse padjadesse.<\/p>\n

\nSellukohal hoitamine, mis on valmistatud peenest, tihedast ja mehaaniliselt tugevast klaudrist, millel on spetsiaalne t\u00e4idis, v\u00f5ib ladustada piiramatu aja jooksul kuivas ja soojas keskkonnas, kuni seda on vaja. See ei sisalda mineraalikiude, on vastupidav ilmastiku korrosioonile ja niiskusele. M\u00f5ned tootjad garanteerivad, et nende padjad suudavad kaua kesta niisketes ventileerimata ruumides.<\/p>\n

\nTulekindlad padjad andmeserverites on v\u00e4ikesed kerged tellised, millega on mugav kattuda peamiste kaablitega, t\u00e4ielikult katabavad avad. Paigaldades need tihedalt kaablite ja seina vahele, saavutatakse hea tulekindlus. Saladus peitub selles, et padjad tulekahju korral paisuvad mitu korda, \u00fcletades oma algset mahtu. Nii saavutatakse t\u00f5hus tihend inseneri l\u00e4bip\u00e4\u00e4sude \u00fcmber. Tulekindlad padjad suudavad tulele vastu pidada kuni 4 tundi. See on palju. Nelja tunni jooksul peab andmeserverite tuleohutus s\u00fcsteem suutma toime tulla igasuguste tulekahjude tekkimisega.<\/p>\n

Selliste padjade eeliseks on see, et need pakuvad kuiva, puhta ja lihtsalt paigaldatava lahenduse. See on otsustav tegur nii olulise objekti, nagu andmeserver, jaoks. Lisaks, kuna andmeserveri seadmeid uuendatakse regulaarselt, on v\u00f5imalus kiiresti lisakaableid l\u00e4bi seina viia, ei h\u00e4vitades seda peaaegu t\u00e4ielikult, hinnatud v\u00e4ga k\u00f5rgelt. Nii et padjad on andmeserveris h\u00e4davajalikud.<\/p>\n
