Comparable in effectiveness, it is cheaper to implement and operate. Moreover, it theoretically avoids the risk of liquid leaks inside expensive server equipment.<\/p>\n<p><\/p>\n<p>Last year, our first experimental rack was installed in the DataPro data center. It consists of forty identical Supermicro servers. The first twenty of these have a standard cooling system, while the next twenty have been modified. The aim of the experiment is to test the suitability of our cooling system in a real data center, in a real rack, with real servers.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" alt=\"KTT in server solutions \u2014 what does it look like?\" src=\"\/wp-content\/uploads\/e36280c51148bec3d9c8444a4300eacb.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/p>\n<p><\/p>\n<p>I apologize for the quality of some photos.

At the bottom \u2014 the heat exchange bus with compression devices for unusual, (almost) fanless servers. Fans remain only for cooling the memory.

It will also be located at the DataPro data center. But what do we need for this? Nothing too complicated \u2014 forty identical hot servers. <\/p>\n<p><\/p>\n<p>We are ready to purchase some hot servers, even if they are not brand new, for our needs. But before that, it would be a missed opportunity not to inquire within the Habr community. Perhaps someone would like to contribute their hardware to our experiment?<\/p>\n<p><\/p>\n<p>In that case, we would have the chance to work with something much newer than what we would acquire ourselves. And, significantly more valuable, this would operate under real, rather than synthetic, loads.<\/p>\n<p><\/p>\n<p>In exchange from us \u2014 free integration of our cooling system into your server rack. The approximate market value of such an upgrade is about 1.5 million rubles. From our partners, DataPro, there is a discount for placing such a modified rack in their data center. The size of the discount will be discussed further with the interested party. <\/p>\n<p><\/p>\n<p>We have the ability to make modifications to server equipment while maintaining warranty obligations. Partnerships have already been established with Lenovo, IBM, and DELL, and we are working on expanding this list. <\/p>\n<p><\/p>\n<p>I would be happy to see all the brave souls in private messages. <noindex><a rel=\"nofollow\" href=\"https:\/\/habr.com\/ru\/users\/webself\/\" class=\"user_link\">webself<\/a><\/noindex> here on Habr or through any contact listed in my profile.
