VaultFS can use any SMR (or CMR, or inter mixed, or capacity) disk

[Enquiries]

Our parallel distributed VaultFS (Vault file system for datacenters) can intermix CMR with SMR (latest tested is WD HC690 30TB) and any intermixed capacities.

ZFS can do neither. ZFS is limited to a single server.

Lustre can do SMR with difficulty, Fraunhofer's BeeGFS and CERN's EOS cannot.

None of the above have built-in parity (they depend upon layering above a ZFS scheme).

VaultFS overcomes all these limitations. You are welcome to try on a (possibly mixed) cluster of i86 or ARM.

Thank you for reaching out and sharing information about VaultFS. It’s impressive to hear that VaultFS supports mixed SMR and CMR drives—including large-capacity models like the WD HC690 30TB—and offers flexibility that traditional systems like ZFS, Lustre, and BeeGFS currently do not.

Your points on integrated parity and the ability to scale across mixed architecture clusters (x86 and ARM) are particularly interesting, especially for large-scale or edge use cases where hardware uniformity isn’t always possible.

I’ll take a closer look at the VaultFS entry on Wikipedia and explore your offering in more depth. If you have additional documentation or benchmarks comparing VaultFS with ZFS or other file systems in mixed-disk environments, I’d be happy to review them.

Thanks again for the introduction—this could be a valuable solution for high-capacity, heterogeneous environments.
