Has Anyone Used Refs Filesystems For Vmses?
A recent internal discussion asked the question about what filesystems are supported by the various VMS's. On the Windows side we usually see NTFS.
It was brought up because a customer asked about ReFS which was a new filesystem available in Server2012.
Resilient File System (ReFS), codenamed "Protogon", is a Microsoft proprietary file system introduced with Windows Server 2012 with the intent of becoming the "next generation" file system after NTFS.
It has support for built in recovery and very large volume support. Out of curiosity I found a Microsoft comparison about it here ReFS vs NTFS
Has anyone heard of this filesystem being supported in any VMS?
Has anyone tried using it?
No, but it would be interesting to hear of someone trying it. It does seem like it is inevitable that 5 years down the road we will be forced to use it due to volume size limits on NTFs. Either that or making a bunch of separate partitions.
I just formatted a disk as ReFS and network optix does recognised the disk.
It seems to be working fine.

That makes sense. I can't comment on Milestone, but in general I don't think most software vendors are using proprietary filesystem features. There's limited value in doing so, and very high risk of locking yourself into a single filesystem.
For Windows-based applications, as long as you utilize .NET or the basic API's provided by the language, the specifics of the filesystem are abstracted away and are essentially irrelevant.
As long as you're not taking advantage of these features of NTFS at the application level, it's probably safe to try ReFS:
The following features are unavailable on ReFS at this time:
| Functionality | ReFS | NTFS |
|---|---|---|
| File system compression | No | Yes |
| File system encryption | No | Yes |
| Data Deduplication | No | Yes |
| Transactions | No | Yes |
| Hard links | No | Yes |
| Object IDs | No | Yes |
| Short names | No | Yes |
| Extended attributes | No | Yes |
| Disk quotas | No | Yes |
| Bootable | No | Yes |
| Supported on removable media | No | Yes |
| NTFS storage tiers | No | Yes |
