In GKE version 1.37.0-gke.3570000 and later, you can split each Local SSD on a node between ephemeral storage and raw block storage. When you create a cluster or node pool, use the capacity property of the --ephemeral-storage-local-ssd flag to set how much Local SSD capacity GKE formats for ephemeral storage.
