Microsofts new filesystem =)

[HFS+]

Finally Microsoft has made a new filesystem! (besides fat filesystem family)

It is called REFS!

The key features of ReFS are as follows (note that some of these features are provided in conjunction with Storage Spaces).

Metadata integrity with checksums
Integrity streams providing optional user data integrity
Allocate on write transactional model for robust disk updates (also known as copy on write)
Large volume, file and directory sizes
Storage pooling and virtualization makes file system creation and management easy
Data striping for performance (bandwidth can be managed) and redundancy for fault tolerance
Disk scrubbing for protection against latent disk errors
Resiliency to corruptions with "salvage" for maximum volume availability in all cases
Shared storage pools across machines for additional failure tolerance and load balancing

However it does look like a clone of ZFS or BTRFS though, but who cares?

NTFS isn't Microsoft's?

I am actually very happy MS cloned ZFS. Good for them, good for all of us.

 

[greenhawk]

that sounds good, so when is it on offer to the home market and not the big iron data warehousing?

It's just a rewrite of NTFS and renamed for release under Windows 8.

more like CSV. thin provisioning, raid-1,1+1,raid-5 - slick stuff here.

too bad you can't boot off it.

where does it say that?

It will be only in Windows Server 8 at first for non-boot volumes only, then it will come to Windows 8 but still non-boot volumes only, then they will let you boot off of it. They are not giving any kind of timelines or even hints at when they will release these upgrades to ReFS.

This plus Storage Spaces has me *really* looking forward to Windows 8's release.

Me too, but those aren't the only reasons!

It would only be good news if MS didn't throw in a bunch of patents in their version of ZFS, to prevent others from supporting it.

then it would be called Linux. lol

NTFS isn't Microsoft's?

Regardless of it's origins, it's effectively been theirs for at least 2 decades. I believe it started with their collaboration with IBM and thus has some roots in HPFS (and shares the partition ID which is just plain dumb) but can't find any proof either way.

then it would be called Linux. lol

Linux is a filesystem now?

1. How this in any way different from NTFS?
2. How does this in any way make it not a superior FS to NTFS

 

[HFS+]

if only if apple would implement ZFS instead of hfs+

Apple would never do something so technically beneficial to their users. And with Oracle's purchase of Sun, I would be leery of doing anything with ZFS as well.

Not going to be on initial realease of WIN 8, will be on MS Exchange Server 8. Might show up in a service pack for WIN 8.

I never said it was any different than NTFS it terms of 3rd party support, and I didn't say it wasn't superior to what windows has now...
I just meant that it would have been good news if they would open it up from the start so everyone can adopt it, instead of only MS machines.
As it is now, I wouldn't call it good news since everyone only using later editions of windows 8 (no backports to vista/7 it seems?) can use it.

I see what you mean...
then again, I would rather have ZFS, BTRFS, and REFS (assuming its as good as it sounds and not another overhyped junk from MS) segmentation than sticking to inferior FS based on tech and assumptions that have been obsolete for decades such as NTFS and Ext4. based on decades old tech doesn't mean its decades old just FYI... they are far ahead of their predecessors like the original FAT. But still very primitate compared to ZFS, BTRFS, and (presumably) REFS

 

[HFS+]

ext4 is based off of ext2 which is an ancient filesystem, except with extent supports

Has Microsoft ever designed their first file system yet? Do they even know how? Or did Microsoft steal all their file system designs?

Without some kind of third party test, how does the average person know anything about file system design? It is all Latin!

If by steal you mean "buy out the company that designed it for a pittance" then yes they always do that. But they can have those guys design it. Since buying a company gets you employees too.
