A lot of them actually. Ceph personally I've used. But there's a ton, some open source, some paid. Backblaze has a product Buckets or something. Dell powerscale. Cloudian has one. Nutanix has one.

Ceph is awesome for software defined storage where you have multiple storage nodes and multiple storage devices on each. It's way too heavy and resource intensive for a single machine with loopback devices.

I've been looking at microceph, but the requirement to run 3 OSDs on loopback files plus this comment from the docs gives me pause:

`Be wary that an OSD, whether based on a physical device or a file, is resource intensive.`

Can anyone quantify "resource intensive" here? Is it "takes an entire Raspberry Pi to run the minimum set" or is it "takes 4 cores per OSD"?

Edit: This is the specific doc page https://canonical-microceph.readthedocs-hosted.com/stable/ho...

    Ceph has multiple daemons that would need to be running: monitor, manager, OSD (1 per storage device), and RADOS Gateway (RGW). If you only had a single storage device it would still be 4 daemons.

ceph depends a lot on your use case

minio was also suited for some smaller use cases (e.g. running a partial S3 compatible storage for integration tests). Ceph isn't really good for it.

But if you ran large minio clusters in production ceph might be a very good alternative.
