They needed a tailored, research-ready platform that could scale, adapt, and deliver consistently.

VMs wurden mit minimaler Unterbrechung \u00fcbertragen, und die Ausfallzeit beschr\u00e4nkte sich auf nur ein oder zwei Tage. <\/p>\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cDKRZ\u2019s transition to FishOS was smooth indeed: it was <strong>a well-orchestrated process<\/strong> from both sides <strong>without major disruptions<\/strong>.

Seit der FishOS-Implementierung hat das DKRZ seine Rechenkapazit\u00e4t mehr als verdreifacht \u2013 von 268 auf 928 Kerne bis 2025. Der Wechsel von Bare-Metal-Servern zu VMs erm\u00f6glichte eine verbesserte Ressourcennutzung und gr\u00f6\u00dfere Flexibilit\u00e4t, insbesondere da Projekte wie die <a href=\"https:\/\/esgf.llnl.gov\/\" target=\"_blank\" rel=\"noopener\" title=\"\"><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-primary-1-color\">Earth System Grid Federation (ESGF)<\/mark><\/a> skalierbare, cloud-native Architekturen erforderten.  <\/p>\n\n<p class=\"wp-block-paragraph\">ESGF ist eine Peer-to-Peer-Datenf\u00f6deration, die globalen Zugang zu Klimamodellausgaben und Beobachtungsdatens\u00e4tzen bietet. In diesem Rahmen spielt das DKRZ eine doppelte Rolle als Datenknoten und Gateway und hilft dabei, den nahtlosen Austausch und die Analyse massiver Datens\u00e4tze zwischen Institutionen weltweit sicherzustellen. <\/p>\n\n<p class=\"wp-block-paragraph\">Das Storage-Backend erhielt ebenfalls ein gro\u00dfes Upgrade. Der Ceph-Cluster wurde in ein <strong>Vollflash-System<\/strong> umgewandelt, wodurch die Kapazit\u00e4t von <strong>140TB auf 265TB<\/strong> erh\u00f6ht wurde. Diese \u00c4nderung verbesserte die Leistung f\u00fcr Workflows mit hohem Durchsatz und gro\u00dfangelegte Simulationen dramatisch.  <\/p>\n\n<p class=\"wp-block-paragraph\">Um alles modern und stabil zu halten, folgt das DKRZ einem regelm\u00e4\u00dfigen Upgrade-Zyklus \u2013 etwa einmal im Jahr \u2013 und stellt sicher, dass Forscher immer Zugang zu aktuellen Werkzeugen haben, ohne das Risiko einer Systemunterbrechung einzugehen.<\/p>\n\n<h4 class=\"wp-block-heading\"><strong>Eine Self-Service-Cloud, konzipiert f\u00fcr Wissenschaftler<\/strong><\/h4>\n\n<p class=\"wp-block-paragraph\">Heute betreibt das DKRZ zwei Virtualisierungsumgebungen: eine zur Unterst\u00fctzung zentraler Infrastrukturdienste wie Authentifizierung und E-Mail, und eine andere \u2013 eine FishOS-betriebene OpenStack-Cloud \u2013 speziell f\u00fcr Forscher zugeschnitten.<\/p>\n\n<p class=\"wp-block-paragraph\">Dieses Self-Service-Setup hat sich als bahnbrechend erwiesen. Anstatt auf Systemadministratoren zu warten, k\u00f6nnen Forscher nun Recheninstanzen starten, ihre Simulationen durchf\u00fchren, Ergebnisse analysieren und Erkenntnisse teilen \u2013 alles nach ihrem eigenen Zeitplan. <\/p>\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-1024x576.png\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-1024x576.png\" alt=\"\" class=\"wp-image-72507\" srcset=\"https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-1024x576.png 1024w, https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-300x169.png 300w, https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-768x432.png 768w, https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-1536x864.png 1536w, https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote-1390x782.png 1390w, https:\/\/www.sardinasystems.com\/wp-content\/uploads\/2025\/04\/Carsten-quote.png 1600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n<p class=\"wp-block-paragraph\">Diese dezentralisierte und flexible Cloud bringt das DKRZ n\u00e4her an die Art und Weise, wie moderne Forschung funktioniert \u2013 agil, schnell beweglich und global vernetzt.
