Thanks. The part that surprised me most was how well ZFS fits object storage and extended to pNFS too!

ZeroFS doesn't exploit ZFS strengths with no native ZFS support, just an afterthought with NBD + SlateDB LSM Good for small burst workloads where everything kept it in memory for LSM batch writes. Once compaction hits all bets off with

Yes that is the value prop. Cheap S3 instead of expensive EBS. EBS limitations: - Per-instance throughput caps - Pay for full provisioned capacity whether filled or not S3: - Pay only for what you store - No per-instance bandw

For RDBMS pages on object storage - you might be thinking of Neon.tech. They built a custom page server for PostgreSQL that stores pages directly on S3.

I hope you are not having that massive storage storage on public-cloud then you would need MayaNAS to reduce storage costs. For S3 as frontend use MinIO gateway - serves S3 API from your ZFS filesystem

It is all part of ZFS architecture with two tiers: - Special vdev (SSD): All metadata + small blocks (configurable threshold, typically <128KB) - Object storage: Bulk data only If the workload is randomized 4K small data blocks - tha

Yes, this is a core use case ZFS fits nicely. See slide 31 "Multi-Cloud Data Orchestration" in the talk. Not only backup but also DR site recovery. The workflow: 1. Server A (production): zpool on local NVMe/SSD/H

The fun part is you can even develop from Linux using MinGW32 Cross Compile environment which produces native windows programs. Crossmeta FUSE also includes sshfs, fuse-nfs for remote file access and s3backer to connect to any S3 compatible

It has NO low level fuse api https://github.com/billziss-gh/winfsp/issues/94 Newer FUSE version 3 mostly address their limitations within Linux implementation. It adds support for concurrent writes and large

Crossmeta kernel has read/write support for XFS and EXT2/3/4 It has readonly support for reiserfs,Apple HFS+ All kernel drivers can be unloaded when not in use. From FUSE it has support for sshfs and NFS client V3 and V4.

The alternative project has no FUSE low-level API support. This is required to implement any real file system with FUSE on windows. Also they have dependency on cygwin project if your code requires some POSIX semantics, which they all do si
