Apple Looking To Port ZFS for Mac OS X?

According to an OpenSolaris mailing list, the ZFS team at Sun has been contacted by Apple's Filesystem Development Manager to discuss porting ZFS to Mac OS X.

ZFS is a relatively new open-source file system backed by Sun. As such, it is included in recent versions of Solaris for SPARC and x86 architectures. A comparison of HFS+ (what Mac OS X currently uses as its default file system) and other file systems including ZFS can be found on this wikipedia page.

One of ZFS's features is "adaptive endian-ness", meaning that you can use a disk with a ZFS filesystem on either a big-endian or little-endian platform and it's portable back and forth.

With its variable-size adaptive block sizes and constant-time directory operations, it promises great performance too.

Apple's changing their file system with 10.5?

This could only be a good thing? Perhaps a proverbial slap in the face to MS after their non change with Vista? (j/k) I understand it is much deeper than that.

So what you would end up with is one little, two little, three little endian?

Sorry...

HFS+ can do this too, if I'm not mistaken... The Macintels are still using HFS+, right? Can't you still interchange them?

No, this is most likely the next system. If Apple has JUST contacted Sun, it wouldn't be for inclusion in an OS that is probably going to be released near the end of the year or beginning of next.

Ummm....in English please?

Who cares about this stuff. The average consumer sure doesn't. Just show us the merchandise!

So....ZFS can store "16 billion billion times the capacity of current 64-bit systems" (acc. to wikipedia). So I would actually expect MS to integrate this into Vista, which is estimated to be 16 billion billion times the size of XP.

Ah. Good point. Back to writing my paper...

Thats a 16 billion billion better chance of a BSOD

The maximum size of a ZFS file system, file, or attribute is 16 exabytes, just like HFS+. ZFS just has so many different improvements that it's quite neat. I'm looking forward to it being ported over, as I'm downloading Solaris for x86 to play around with ZFS as we speak.
