Update: It is official. See here. Then come back and read the rest of this post. Thanks to alert reader Oskar for the tip.
French website Mac4Ever reports – thanks to Babelfish translation:
. . . the few innovations of Leopard, one read these last months, several rumours on the integration of a new filing system, the ZFS, which presents a revolution in the field of the storage of data. This rumour seems to be confirmed, since one sees finally apparaitre in the utility of discs of Leopard, an option to create images and partitions in this format.
They include this section of a screenshot:
Which seems pretty convincing. Or at least someone had fun with Photoshop. For the record, I believe.
I forget, so why is this cool?
See ZFS On Leopard: How Cool Is That? for more details, but the main coolness is:
- No more disk utilities. The entire data store is self-validating.
- No RAID controllers needed: ZFS gives you fast RAID for free. Just add drives.
- No more volumes and, therefore, no more volume management. ZFS eliminates the whole volume concept. Add a disk to your system and it joins your storage pool. More capacity. Not more management.
- Easy, fast backup through snapshots which means that Time Machine could give you a view of your data every hour on the hour, all day long.
FWIW, StorageMojo called it first . . .
Competitive analysis is not for the faint of heart, and I confess I wavered on whether or not Apple was really doing ZFS, until the iTV announcement three months ago. Then it all became clear – to me – while the silence from the rest of the Mac community was deafening (see Means, Motive & Opportunity: Apple Kills the Media Center PC). I even tried to bet the inimitable John Siracusa of Ars Technica a drink – only to find he doesn’t bet or drink!
The StorageMojo take
Why is this even slightly important? For the same reason I said four months ago:
StorageMojo.com has devoted time to this issue because today’s computer business is largely driven by consumer computing, not enterprise computing. Putting a really modern integrated file and storage management system on a consumer OS would raise the bar for everyone else.
No doubt Apple will first recommend ZFS for Mac OS X Server, just as they did with HFS+. Yet it won’t be long before it becomes the default file system, and not a moment too soon.
Update: I updated this post with some additional explanatory material, for those few people who haven’t been following ZFS and Leopard as avidly as I have.
YAU: Looks like Leopard’s Disk Utility also supports iSCSI natively. Another plus.
Comments welcome, of course.
