Native ZFS VDEV for Object Storage (OpenZFS Summit)

4 months ago

MayaNAS and MayaScale were presented at OpenZFS Developer Summit 2025 in Portland, Oregon.
objbacker.io introduced as a native ZFS VDEV implementation for object storage, bypassing FUSE and achieving 3.7 GB/s read throughput.
OpenZFS Summit is a gathering of core developers and engineers maintaining ZFS across platforms.
MayaNAS and MayaScale form the Zettalane storage platform, with a deep dive into objbacker.io.
Cloud storage economics challenge NAS deployments with high costs for EBS and EFS.
MayaNAS leverages ZFS's special device architecture to optimize performance and cost.
objbacker.io uses a native ZFS VDEV type for direct communication with object storage via a character device.
Performance benchmarks show 3.7 GB/s sequential read and 2.5 GB/s sequential write on AWS.
MayaScale offers NVMe-oF block storage with sub-millisecond latency and Active-Active HA clustering.
Both MayaNAS and MayaScale are deployable across AWS, Azure, and GCP with consistent architecture.
The presentation is available on the OpenZFS YouTube channel.
MayaNAS with objbacker.io offers 70%+ cost savings over traditional cloud block storage.
MayaScale caters to latency-sensitive workloads with high IOPS and low latency.
