But if someone needs to sum up a data center\u2019s size using a single number, it\u2019s likely to be a measure of how many megawatts of energy flow into it.<\/span><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">In some respects, this approach makes sense. The major advantage of measuring data center capacity based on power input offers is that it\u2019s a relatively consistent proxy for how many servers and workloads a data center can support. More workloads require more power, so more power generally correlates with more capacity.<\/span><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">On the other hand, a major downside is that total energy input doesn\u2019t always translate linearly to total server capacity. A server&#8217;s power requirements can fluctuate widely based on its components, the specific workloads it hosts, and the efficiency of the cooling system that protects it.<\/span><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">For this reason, total power input measurements are more meaningful if they\u2019re accompanied by PUE metrics, since PUE reflects which percentage of available energy inside a data center can be used to power servers. For example, a 100 MW data center with poor power usage effectiveness might not be able to support as many workloads as an 80 MW data center that uses electricity more efficiently, thanks to energy-saving innovations like <\/span><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\"><a class=\"ContentText-BodyTextChunk ContentText-BodyTextChunk_link\" target=\"_self\" href=\"https:\/\/www.datacenterknowledge.com\/cooling\/don-t-fear-immersion-liquid-cooling-in-the-data-center\">immersion cooling<\/a><\/span><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">.<\/span><\/p>\n<p data-component=\"related-article\" class=\"RelatedArticle\"><span data-testid=\"related-article-title\" class=\"RelatedArticle-Title\">Related:<\/span><a class=\"RelatedArticle-RelatedContent\" href=\"https:\/\/www.datacenterknowledge.com\/cooling\/a-guide-to-data-center-water-usage-effectiveness-wue-and-best-practices\" target=\"_self\" data-discover=\"true\">A Guide to Data Center Water Usage Effectiveness (WUE) and Best Practices<\/a><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">That said, other metrics for assessing data center capacity, like square footage or server rack count, are also imperfect measurements of what a data center can actually do. The size of servers and server racks can vary, so server room square footage doesn\u2019t translate neatly to how much infrastructure a facility can host. The number of servers you can fit in a rack can also vary. And even when physical space is not a constraint, cooling limitations might be.<\/span><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">Thus, if the industry defaults to focusing on total energy input, it may be because there is no better alternative.<\/span><\/p>\n<h2 class=\"ContentText ContentText_variant_h2 ContentText_align_left\" data-testid=\"content-text\" id=\"Size Matters: Accurately Calculating Data Center Capacity\" style=\"scroll-margin-top:10rem;scroll-snap-margin-top:10rem\">Size Matters: Accurately Calculating Data Center Capacity<\/h2>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">Ultimately, the best way to measure data center size is by considering a number of factors, including but not limited to energy input \u2013 and to remember that assessments of data center capacity only roughly correlate with how many workloads a facility can actually host.<\/span><\/p>\n<p class=\"ContentParagraph ContentParagraph_align_left\" data-testid=\"content-paragraph\"><span class=\"ContentText ContentText_variant_bodyNormal\" data-testid=\"content-text\">Data centers are inherently complex, and there\u2019s no single size metric that can capture that complexity without losing a lot of detail.<\/span><\/p>\n<\/div>\n<p><script defer=\"\" async=\"\" src=\"https:\/\/connect.facebook.net\/en_US\/sdk.js#xfbml=1&amp;version=v18.0\" data-ot-ignore=\"true\"><\/script><br \/>\n<br \/><\/p>","protected":false},"excerpt":{"rendered":"<p>You don\u2019t measure the size of a car based on how much gas it can fit in its tank.
