Fred,

This feature is being touted by many rumours sites around the web, many of them showing different methods of getting to the feature.

I can’t possibly see how you’ve come to the conclusion that this is fake.

And for the record, build 326 never existed, not even as an internal build.

“Unless this is from the latest Apple Internal build (326), THIS IS FAKE.”

Or its intel only …

Looks like a fake. I’m using Leopard Build 321 on PPC, and there’s no ZFS support there in Disk Utility. In fact, in that build they’ve removed UFS and FAT32 from the options, so there’s only HFS with and without Journaling.

Unless this is from the latest Apple Internal build (326), THIS IS FAKE.

To spatialguru: Time Machine is built solely on HFS at this point. It is likely that ZFS will eventually be supported.

So that’s how they will handle the underlying requirements of their time machine technology.. I was wondering how they’d make it rock…

Wonderful insight, Gerrit.

Would you mind taking a look at the following PDF (http://www.opensolaris.org/os/community/zfs/docs/zfs_last.pdf), page 19 lists the figures I gave, how do they match up with those of Wikipedia?

*ZFS has a data storage capacity of 256 quadrillion zettabytes and a maximum file size of 16 exabytes (that’s 17179869184 terabytes).*

Practically speaking, ZFS has a maximum volume and maximum file size of 16 exabytes (EB), and that’s actually not equal to 17179869184 terabytes:

In decimal, one exabyte is 10^18 bytes (one quintillion bytes, using US English place value names), and one terabyte is 10^12 byes (one trillion bytes, US English place values). In terms of usable space (capacity), one binary exabyte (exbibyte, EiB) is 1024^6 = (2^10)^6 = 2^60 bytes, and one binary terabyte (tebibyte, TiB) is 1024^4 = 2^40 bytes.

A little stochiometry tells us:

1. 16EB * (10^18 bytes/EB) * (10^-12 TB/byte) = 16 * 10^6 TB = 16,000,000 (sixteen million terabytes in 16 exabytes).

2. 16 EiB * 2^60 bytes/EiB * 2^-40 TiB/byte = 16 * 2^20 = 2^4 * 2^20 = 2^24 = 16,777,216 (sixteen million seven hundred seventy-seven thousand two hundred sixteen binary terabytes in 16 binary exabytes).

3. 17,179,869,184 TiB is actually 16 binary zettabytes (2^70 bytes). One zettabyte is roughly one sextillion (US English units) bytes, 10^21. Even though the filesystem’s name is ZFS, the limitations are presently in exabytes (see the Wikipedia article):

17,179,869,184 TiB * 2^40 bytes/TiB * 2^-60 EiB/byte = 16,384 EiB
17,179,869,184 TiB * 2^40 bytes/TiB * 2^-70 ZiB/byte = 16 ZiB

Solaris can’t yet [officially] boot from ZFS, so the odds that OS X is booting from ZFS is slim to none. However, ZFS is an awesome filesystem and anyone with an OS X non-root storage array will probably want to convert. I’ve gone ahead and built a ZFS stoarge server running OpenSolaris for my OS X machine, though native support for ZFS on the Mac is great news, though this brings up another question…When will Apple finally take all of Solaris and build it’s GUI easy-to-use-goodness on top?Now that would be an OS to take over in the corporate environments as well as at home.

Hope they’re sticking close to the current code; lately ZFS has added features like hot spares and RAIDZ2 (~RAID-6, two parity disks). Seems to keep getting better and better. (I also had a plan to convert a home storage server from Linux to Solaris Express; now I can just keep it all-Mac…)

Ok - it is always cool when a ‘better’ technology gets included, but what I can’t stop asking myself is this… Why did they do it? Apple usually only makes moves like this when there is serious product around the decision. So my other question is when will this product be avail? Is it a XServe Raid ZFS based on Leopard…?

Hooray for Sun/ZFS and Apple! ZFS will make an outstanding desktop filesystem. One of it’s built-in management features allows you to “snapshot” points in time as backups, which sounds very much like apple’s “time travel” feature - I wonder if there’s been some discussion there?
