WekaFS vs Ceph for AI GPU Starvation: A Storage Showdown

By PulseAugur Editorial · [1 sources] ·

WekaFS and Ceph are compared for their effectiveness in AI training pipelines, specifically addressing GPU starvation. WekaFS offers extreme DPDK speed but comes with high software licensing fees, while Ceph provides petabyte-scale storage on 100G networks with no lock-in. The article also suggests using iommu=pt in GRUB to fix NVMe CPU spinlocks and mandates the use of CephFS (RWX) over RBD for shared LLM weights in Kubernetes environments. AI

IMPACT Optimizing storage solutions can reduce costs and improve efficiency in AI training, potentially accelerating model development.

RANK_REASON The item discusses storage solutions for AI training pipelines, which is a technical tool/infrastructure topic rather than a core AI release or significant industry event.
