The OS by default should cap the usage to 63 cores. The last core can then be used to run essential software, like ssh.<br/><br/>The performance reduction is only about 1/64, that is 1.5%. At the same time, you can be sure the system stays stable and reachable via ssh. 2025-02-28T20:05:13Z https://yabu.me/nevent1qqszg38prqpmc78ep8jhz5rde50naheec0k9pfnvyur0404uk99tmwqzyrpza8ykuwzkyw8qhh9x3ylrgdfd5me8x5tfrn9pq8a5fjjhf4nzxncjgwv In reply to <a href='/nevent1qqsfyz4slmv6xzu8sdsu42gsd68ashfhxvq4q4ewyu838rfdq5a9ync4r3pn9'>nevent1q…3pn9</a><br/>_________________________<br/><br/>Popular music streaming services (Apple Music, Deezer...) claim they have more than 90mln songs available.<br/><br/>Let&#39;s say you need to store 180mln songs, doubling Apple Music&#39;s library.<br/><br/>Let&#39;s say a full song takes 10MB.<br/><br/>10MB * 180M = 1800MMB = 1.8PB ?<br/><br/>If you store them in HDDs of 16TB (Seagate sells them at €200), you need <br/><br/>113 HDDs, so at least €22.600 worth of HDDs.<br/><br/>But you need at least a RAID 1 setup, so 226 HDDs<br/><br/>You can store the entire music library ever produced inside a shed 2024-09-24T20:00:48Z
