Un refroidissement efficace des data centers am\u00e9liore les performances des serveurs et optimise l\u2019ensemble des processus op\u00e9rationnels. C\u2019est pourquoi diverses m\u00e9thodes de refroidissement ont \u00e9t\u00e9 d\u00e9velopp\u00e9es au fil des ann\u00e9es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-81d230e e-flex e-con-boxed e-con e-parent\" data-id=\"81d230e\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5ab0d38 elementor-widget elementor-widget-text-editor\" data-id=\"5ab0d38\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Pourquoi le refroidissement des data centers est-il important ?<\/h2><p>Les data centers abritent un grand nombre de serveurs utilis\u00e9s \u00e0 des fins diverses. Ces serveurs ont un point commun : leur charge de travail \u00e9lev\u00e9e, qui pousse leurs processeurs et leurs puces \u00e0 d\u00e9gager une quantit\u00e9 importante de chaleur.<\/p><p>Pour mieux le comprendre, pensez \u00e0 votre ordinateur portable ou \u00e0 votre ordinateur personnel. Lorsqu\u2019il est sollicit\u00e9 au-del\u00e0 de sa charge habituelle, remarquez avec quelle intensit\u00e9 le ventilateur fonctionne et combien de chaleur l\u2019appareil produit.<\/p><p>Les serveurs \u00e9tant souvent qualifi\u00e9s de superordinateurs, ils produisent eux aussi beaucoup de chaleur. Si cette chaleur n\u2019est pas \u00e9vacu\u00e9e, les performances des serveurs diminueront progressivement et ceux-ci ne pourront plus fonctionner aussi efficacement qu\u2019auparavant. Un environnement comme un data center, qui h\u00e9berge de nombreux serveurs, doit donc \u00e9galement disposer d\u2019un syst\u00e8me de refroidissement adapt\u00e9.<\/p><p>Aujourd\u2019hui, les syst\u00e8mes de refroidissement sont devenus l\u2019un des principaux crit\u00e8res pris en compte par les entreprises lorsqu\u2019elles choisissent un data center. Compte tenu de leur importance pour les performances des serveurs, de nombreuses m\u00e9thodes de refroidissement ont \u00e9t\u00e9 mises au point pour les data centers. Certaines se sont r\u00e9v\u00e9l\u00e9es pratiques, d\u2019autres non. Une chose est toutefois certaine : \u00e0 mesure que l\u2019utilisation des serveurs s\u2019est intensifi\u00e9e, le besoin de nouvelles technologies de refroidissement s\u2019est lui aussi accru.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-feefc5a e-flex e-con-boxed e-con e-parent\" data-id=\"feefc5a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-c3f1a76 elementor-widget elementor-widget-text-editor\" data-id=\"c3f1a76\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>M\u00e9thodes de refroidissement des data centers<\/h2><p>Plusieurs m\u00e9thodes permettent de refroidir les data centers ; nous allons les examiner dans cette section.<\/p><ul><li><h3>Refroidissement par air<\/h3><\/li><\/ul><p style=\"padding-left: 40px;\">Cette m\u00e9thode de refroidissement utilise des ventilateurs, des syst\u00e8mes de climatisation, des bouches d\u2019a\u00e9ration et d\u2019autres \u00e9quipements pour cr\u00e9er un flux d\u2019air. Le refroidissement par air \u00e9vacue l\u2019air chaud produit \u00e0 l\u2019int\u00e9rieur du data center et le remplace par de l\u2019air frais. Il s\u2019agit de l\u2019une des m\u00e9thodes les plus r\u00e9pandues, pr\u00e9sente dans de nombreux data centers.<\/p><p style=\"padding-left: 40px;\">Par le pass\u00e9, le refroidissement par air suffisait \u00e0 r\u00e9pondre \u00e0 de nombreux besoins. Aujourd\u2019hui, cependant, les charges de travail ont augment\u00e9 en volume comme en intensit\u00e9, si bien que cette m\u00e9thode n\u2019est plus forc\u00e9ment adapt\u00e9e ni suffisamment efficace pour tous les data centers.<\/p><p style=\"padding-left: 40px;\">Le refroidissement par air est g\u00e9n\u00e9ralement utilis\u00e9 pour les baies dont la densit\u00e9 de puissance est inf\u00e9rieure \u00e0 20 kW.<\/p><ul><li><h3>Refroidissement liquide<\/h3><\/li><\/ul><p style=\"padding-left: 40px;\">Dans le refroidissement liquide direct, le liquide de refroidissement est achemin\u00e9 par un r\u00e9seau de tuyaux jusqu\u2019aux composants qui produisent de la chaleur, comme les CPU et les GPU. En traversant des \u00e9l\u00e9ments tels que les plaques froides, le liquide absorbe la chaleur. Une fois r\u00e9chauff\u00e9, il retourne dans la boucle de refroidissement pour \u00eatre refroidi puis remis en circulation.<\/p><p style=\"padding-left: 40px;\">Dans cette m\u00e9thode, le liquide est en contact direct avec les puces ou leurs composants de refroidissement, mais le serveur n\u2019est pas enti\u00e8rement immerg\u00e9.<\/p><ul><li><h3>Refroidissement par immersion<\/h3><\/li><\/ul><p style=\"padding-left: 40px;\">Dans cette m\u00e9thode, le serveur est enti\u00e8rement immerg\u00e9 dans un liquide. On pourrait croire que cela endommagerait le serveur tout en \u00e9vacuant la chaleur, mais ce n\u2019est pas le cas. Avec le refroidissement par immersion, le serveur est plong\u00e9 dans un liquide non conducteur, ce qui n\u2019endommage aucunement ses composants.<\/p><p style=\"padding-left: 40px;\">Le liquide absorbe la chaleur produite et emp\u00eache le serveur de surchauffer. Cette m\u00e9thode est si efficace qu\u2019elle permet de d\u00e9ployer des \u00e9quipements \u00e0 tr\u00e8s haute densit\u00e9 dans des installations initialement con\u00e7ues pour des densit\u00e9s de puissance faibles ou moyennes.<\/p><p style=\"padding-left: 40px;\">Le refroidissement par immersion peut \u00eatre utilis\u00e9 pour pratiquement tous les types de serveurs et de charges de travail.<\/p><ul><li><h3>Refroidissement par \u00e9vaporation<\/h3><\/li><\/ul><p style=\"padding-left: 40px;\">Comme le refroidissement par air ne suffit plus \u00e0 lui seul \u00e0 r\u00e9pondre aux besoins de nombreux data centers, et que le remplacement complet du syst\u00e8me de refroidissement peut s\u2019av\u00e9rer extr\u00eamement co\u00fbteux, le refroidissement par \u00e9vaporation peut constituer la meilleure option pour ces installations.<\/p><p style=\"padding-left: 40px;\">Des ventilateurs font entrer l\u2019air ext\u00e9rieur dans le data center pour le refroidir. Avant que cet air n\u2019atteigne les \u00e9quipements, l\u2019\u00e9vaporation de l\u2019eau lui retire de la chaleur et abaisse sa temp\u00e9rature.<\/p><ul><li><h3>Free cooling<\/h3><\/li><\/ul><p style=\"padding-left: 40px;\">Le free cooling (refroidissement naturel) est une m\u00e9thode qui exploite les ressources naturelles disponibles pour abaisser la temp\u00e9rature d\u2019un data center lorsque les conditions environnementales s\u2019y pr\u00eatent, ce qui r\u00e9duit la n\u00e9cessit\u00e9 de faire fonctionner en continu les \u00e9quipements de refroidissement conventionnels. Dans cette m\u00e9thode, l\u2019air ext\u00e9rieur ou des sources d\u2019eau naturellement fra\u00eeche peuvent jouer un r\u00f4le important dans le transfert de chaleur.<\/p><p style=\"padding-left: 40px;\">Des technologies telles que les \u00e9conomiseurs, le refroidissement indirect par air, les roues thermiques et les \u00e9changeurs de chaleur \u00e0 plaques peuvent \u00eatre utilis\u00e9es pour mettre en \u0153uvre ce syst\u00e8me de refroidissement.<\/p><p style=\"padding-left: 40px;\">La possibilit\u00e9 d\u2019utiliser cette m\u00e9thode d\u00e9pend du climat et du microclimat du site du data center. Les conditions environnementales du site doivent donc \u00eatre \u00e9valu\u00e9es avec soin avant de la choisir. Lorsque les conditions s\u2019y pr\u00eatent, le free cooling peut r\u00e9duire la consommation d\u2019\u00e9nergie et les \u00e9missions de carbone. Il peut se r\u00e9v\u00e9ler particuli\u00e8rement efficace pour les data centers qui prennent en charge des charges de travail exigeantes comme l\u2019IA et le calcul haute performance

des data centers consiste \u00e0 r\u00e9duire au maximum son impact environnemental. Certaines m\u00e9thodes existantes ont fait leurs preuves et peuvent continuer \u00e0 \u00eatre largement utilis\u00e9es. Cependant, les m\u00e9thodes susceptibles de se g\u00e9n\u00e9raliser \u00e0 l\u2019avenir offrent davantage d\u2019avantages environnementaux et des moyens plus efficaces de g\u00e9rer la chaleur r\u00e9siduelle. En voici quelques-unes :<\/p><ul><li><strong>Refroidissement adaptatif :<\/strong> dans cette m\u00e9thode, l\u2019intelligence artificielle ajuste le niveau de refroidissement en fonction de l\u2019\u00e9tat et de la charge de travail actuels des serveurs. Cela \u00e9vite un refroidissement excessif et une consommation d\u2019\u00e9nergie inutile.<\/li><li><strong>Data centers edge :<\/strong> le recours croissant aux data centers edge permet de traiter les donn\u00e9es au plus pr\u00e8s des utilisateurs. Ces installations peuvent adopter des m\u00e9thodes de refroidissement plus r\u00e9centes, adapt\u00e9es \u00e0 leurs conditions sp\u00e9cifiques.<\/li><li><strong>\u00c9nergie durable :<\/strong> l\u2019utilisation de l\u2019\u00e9nergie solaire et \u00e9olienne, associ\u00e9e \u00e0 des batteries et \u00e0 des syst\u00e8mes de stockage d\u2019\u00e9nergie, peut aider les data centers \u00e0 r\u00e9duire leur consommation d\u2019\u00e9nergie et leur empreinte carbone.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ac1b695 e-flex e-con-boxed e-con e-parent\" data-id=\"ac1b695\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5ddd0c7 elementor-widget elementor-widget-text-editor\" data-id=\"5ddd0c7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Quels grands data centers utilisent le refroidissement liquide ?<\/h2><p>De grands op\u00e9rateurs de data centers comme Google, Amazon et Hetzner se sont appuy\u00e9s pendant de nombreuses ann\u00e9es sur le refroidissement par air. Leurs syst\u00e8mes de refroidissement n\u2019ont pas beaucoup \u00e9volu\u00e9 au cours de cette p\u00e9riode, m\u00eame si certains ont \u00e9galement adopt\u00e9 le refroidissement par \u00e9vaporation. Toutefois, comme ces syst\u00e8mes peuvent \u00eatre co\u00fbteux \u00e0 installer et soulever des pr\u00e9occupations environnementales, notamment en ce qui concerne la consommation d\u2019eau et son rejet dans le milieu naturel, ils ne sont pas utilis\u00e9s partout.<\/p><p>\u00c0 l\u2019heure actuelle, peu de donn\u00e9es ou d\u2019informations d\u00e9taill\u00e9es sont disponibles sur les m\u00e9thodes de refroidissement utilis\u00e9es dans les data centers d\u00e9di\u00e9s \u00e0 l\u2019IA. Cependant, l\u2019infrastructure qui fait fonctionner des plateformes comme OpenAI, Claude et Gemini doit forc\u00e9ment recourir \u00e0 des technologies de refroidissement liquide, au moins pour les serveurs qui traitent des charges de travail extr\u00eamement exigeantes.<\/p><p>En 2018, Microsoft a \u00e9galement immerg\u00e9 au fond de la mer un data center \u00e9tanche de la taille d\u2019un conteneur afin de tester l\u2019id\u00e9e de construire des data centers sous l\u2019eau.

La temp\u00e9rature relativement basse et stable de l\u2019eau de mer environnante contribuait \u00e0 refroidir les serveurs.<\/p><p>Ces serveurs ont fonctionn\u00e9 sous l\u2019eau pendant environ deux ans. Malgr\u00e9 le potentiel consid\u00e9rable du projet pour r\u00e9duire les co\u00fbts de construction et de refroidissement des serveurs, aucune entreprise ni aucun op\u00e9rateur de data center n\u2019a depuis adopt\u00e9 cette approche \u00e0 grande \u00e9chelle.<\/p><p>La construction de data centers sous l\u2019eau pourrait avoir des effets n\u00e9gatifs sur la faune marine et perturber les \u00e9cosyst\u00e8mes aquatiques \u00e0 long terme.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-6f1e4ce e-flex e-con-boxed e-con e-parent\" data-id=\"6f1e4ce\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-00466f7 elementor-widget elementor-widget-text-editor\" data-id=\"00466f7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<h2>Pour finir : comment le refroidissement adaptatif am\u00e9liore-t-il l\u2019efficacit\u00e9 des data centers ?<\/h2><p>Le refroidissement adaptatif s\u2019appuie sur l\u2019intelligence artificielle et sur des donn\u00e9es en temps r\u00e9el pour ajuster en permanence le niveau de refroidissement en fonction de la charge de travail des serveurs et des conditions environnementales.
