Apple considers Sun's ZFS for Mac OS X

ZFS for Mac OS X?

Apple is considering porting Sun's modern performance file system to Mac OS X. Developed for Sun's Solaris 10 operating system, the ZFS file system offers extremely fast performance, support for virtually unlimited capacity, advanced data integrity routines, and more. ZFS, based on a transactional object model, removes most of the traditional constraints on the order of issuing I/Os, which results in "huge performance gains," according to Sun. An email message sent by Sun's Eric Kustarz says that Apple's CoreOS team is interested in porting ZFS to Mac OS X. "Chris Emura, the Filesystem Development Manager within Apple's CoreOS organization is interested in porting ZFS to OS X," the message read. Apple currently uses the HFSX file system, a slightly modified version of the HFS Plus or Mac OS X Extended system.

Sun touts the ZFS as "endian-neutral," allowing users to use storage disks in different computers with different processors. Sun also says that ZFS is the first 128-bit file system for greater storage capacity, offering features that enable "self-healing" or the ability to repair itself. Using 64-bit checksums, the file system is able to detect and correct silent data corruption, according to the company.

"We've rethought everything and rearchitected it," says Jeff Bonwick, Sun distinguished engineer and chief architect of ZFS. "We've thrown away 20 years of old technology that was based on assumptions no longer true today."

If Apple

If Apple go ahead and port this thing, I hope that if the claims are true and Apple starts using it as it's default format that older apps will work with it. Specifically Carbon apps that are from the transition from OS 9 to X. Many of those apps can't use really long file names (no problem) or work with other file systems like UFS. If Apple uses ZFS then they would need to implement it in a way that makes it transparent to these older programs. Many of us still use old versions of apps because they suit us and there isn't anything in the newer versions we need.

The problem would be to make it backward compatible, they'd have to modify the file system to support dual-naming (if it doesn't support it). But, theoretically, most apps shouldn't care if they're written correctly (don't assume a disk format, but use built in API) and let the API be updated.

Then again, Apple doesn't care about backwards compatibility. If the program isn't relatively new, they could care less if they broke compatibility.

Aren't there current issues with writing to NTFS? Shouldn't that be getting dealt with first? Especially since Windows bootable Macs (according to an article I read) can handle fat32, but only read ntfs.

NTFS is always an option, but who knows whether MS has licensing rights to it.

why? oh you missed the signs for the trap you fell in, just because they see a marketing advantage with Boot Camp and it's trivial implementation, Apple is not going to embrace/extend core technologies just because it makes their hardware run Windows better. This is about moving forward…
