The CRS812 seems to be completely sold out too. Both say backorders are expected to fill in November… but I have work to do untouchable from the larcenist hands of big AI and months is a lifetime away.\n\nAnyone know a reputable place where I could get one?\n\nAlternatively, anyone recommend another way to set this cluster up??\n\nI’m non-technical trying to do technical things. It’s been a wonderful moving target for my curiosity but… just a lot. I’ll spare you all the long version of my journey and simply say - thank you.\n\nAlso to Wendell if you see this - you have my appreciation and gratitude", "url": "https://wpnews.pro/news/alternative-400gb-s-switch-for-4-dgx-spark-cluster", "canonical_source": "https://forum.level1techs.com/t/alternative-400gb-s-switch-for-4-dgx-spark-cluster/255948#post_1", "published_at": "2026-09-14 09:57:39+00:00", "updated_at": "2026-09-14 10:05:43.599447+00:00", "lang": "en", "topics": ["ai-infrastructure"], "entities": ["MikroTik", "MikroTik CRS804-4DDQ-hRM", "MikroTik CRS812", "NVIDIA DGX Spark", "Wendell"], "alternates": {"html": "https://wpnews.pro/news/alternative-400gb-s-switch-for-4-dgx-spark-cluster", "markdown": "https://wpnews.pro/news/alternative-400gb-s-switch-for-4-dgx-spark-cluster.md", "text": "https://wpnews.pro/news/alternative-400gb-s-switch-for-4-dgx-spark-cluster.txt", "jsonld": "https://wpnews.pro/news/alternative-400gb-s-switch-for-4-dgx-spark-cluster.jsonld"}}
