Una dintre cele mai eficiente metode de cre\u0219tere a eficien\u021bei energetice a unui centru de date modern \u0219i de reducere a costurilor de exploatare este reprezentat\u0103 de sistemele de izolare. Acestea sunt cunoscute \u0219i sub denumirea de sisteme de contenerizare a coridoarelor calde \u0219i reci. Motivul este c\u0103 principala utilizatoare a puterii excesive \u00een centrul de date este sistemul de r\u0103cire. \u00cen consecin\u021b\u0103, cu c\u00e2t sarcina asupra acestuia este mai mic\u0103 (reducerea facturilor la electricitate, distribu\u021bia uniform\u0103 a \u00eenc\u0103rc\u0103turii, reducerea uzurii sistemelor tehnice), cu at\u00e2t eficien\u021ba energetic\u0103 este mai mare (raportul dintre puterea total consumat\u0103 \u0219i puterea util\u0103 (cheltuit\u0103 pe \u00eenc\u0103rc\u0103tura IT)). <\/p>\n

Aceast\u0103 abordare a c\u00e2\u0219tigat popularitate. Este un standard recunoscut la nivel mondial \u0219i \u00een Rusia a centrelor de date<\/a>. Ce trebuie s\u0103 \u0219ti\u021bi despre sistemele de izolare pentru a le utiliza la maximum eficien\u021ba? <\/p>\n

Pentru \u00eenceput \u2013 cum este construit\u0103 \u00een general \u0219i cum func\u021bioneaz\u0103 sistemul de r\u0103cire. \u00cen centrul de date se afl\u0103 dulapuri de montare (rack-uri) \u00een care este instalat\u0103 echipamentul IT. Acest echipament are nevoie de r\u0103cire constant\u0103. Pentru a evita supra\u00eenc\u0103lzirea, este necesar s\u0103 se furnizeze un flux de aer rece c\u0103tre u\u015fa din fa\u021b\u0103 a dulapului \u0219i s\u0103 se extrag\u0103 aerul cald, care iese din partea din spate. Dar, dac\u0103 \u00eentre cele dou\u0103 zone \u2013 rece \u0219i cald \u2013 nu exist\u0103 o barier\u0103, cele dou\u0103 fluxuri se pot amesteca, reduc\u00e2nd astfel r\u0103cirea \u0219i cresc\u00e2nd sarcina asupra unit\u0103\u021bilor de climatizare.
\nPentru a preveni amestecarea aerului cald \u0219i rece, este necesar s\u0103 se construiasc\u0103 un sistem de contenerizare a aerului.<\/p>\n

\"Sistemele
\n<\/a><\/noindex>
\nPrincipiul de func\u021bionare:<\/u> un volum \u00eenchis (container) acumuleaz\u0103 aerul r\u0103cit, \u00eempiedic\u00e2ndu-l s\u0103 se amestece cu aerul cald \u0219i permi\u021b\u00e2nd dulapurilor cu sarcin\u0103 mare s\u0103 primeasc\u0103 o cantitate adecvat\u0103 de r\u0103cire.<\/p>\n

Loca\u021bie:<\/u> containerul de aer ar trebui s\u0103 se afle \u00eentre dou\u0103 r\u00e2nduri de dulapuri de montare sau \u00eentre un r\u00e2nd de dulapuri \u0219i zidul camerei. <\/p>\n

Construc\u021bie:<\/u> toate laturile containerului care separ\u0103 zonele calde de cele reci trebuie s\u0103 fie delimitate cu perete desp\u0103r\u021bitor astfel \u00eenc\u00e2t aerul rece s\u0103 treac\u0103 doar prin echipamentele IT. <\/p>\n

Cerin\u021be suplimentare:<\/u> Containerul nu trebuie s\u0103 \u00eempiedice instalarea \u0219i func\u021bionarea echipamentelor IT, desf\u0103\u0219urarea comunica\u021biilor, func\u021bionarea sistemelor de monitorizare, iluminat, de stingere a incendiilor, precum \u0219i s\u0103 permit\u0103 integrarea \u00een sistemul de control al accesului \u00een sala de ma\u0219ini.
\nCostul: acesta este un aspect suficient de pozitiv. \u00cen primul r\u00e2nd, sistemul de containerizare nu este, de departe, cea mai costisitoare parte a \u00eentregului sistem de climatizare. \u00cen al doilea r\u00e2nd, nu necesit\u0103 cheltuieli ulterioare pentru \u00eentre\u021binere. \u00cen al treilea r\u00e2nd, are un impact pozitiv asupra economiei, deoarece separarea fluxurilor de aer \u0219i eliminarea punctelor de supra\u00eenc\u0103lzire localizat\u0103 reduc \u0219i distribuie uniform sarcina \u00eentre aer condi\u021bionat. \u00cen general, efectul economic depinde de dimensiunea s\u0103lii de ma\u0219ini \u0219i de arhitectura sistemului de r\u0103cire. <\/p>\n

Recomandare:<\/u> \u00een cazul \u00eenlocuirii echipamentului IT cu unul mai performant, nu este \u00eentotdeauna obligatorie actualizarea aparatelor de aer condi\u021bionat cu modele mai puternice. Uneori, este suficient s\u0103 se instaleze un sistem de izolare, ceea ce poate oferi un rezerv\u0103 de 5\u201310% din capacitatea de r\u0103cire.
