Sun Solaris, OpenSolaris Due to me not working for OSNews these past eight weeks, I've been a bit out of the loop, as I didn't really follow technology news. I did notice that a lot is going on in OpenSolaris land, and today, Oracle has outlined what it has planned for Solaris 11 - and according to some, the fears about OpenSolaris' future were justified.

Also note that ZFS is "rampant layering violation",


ZFS is not a rampant layering violation, it is a re-organisation of the layers.

Instead of 8 or 9 or more layers between the apps and the disk, there are now 4 (physical, DMU, ZPU, filesystem, or something along those lines). Aka, stepping back, looking at the current state of storage, realising that the 30-year-old assumptions are no longer correct, and coming up with something better.

BTRFS is file system only.


Btrfs may have started as a simple filesystem only. But it's now a filesystem, a volume manager, and a RAID engine. With more on the way.

It is designed to be a file system and there is LVM for RAID and other stuff.


Nope, the volume management and RAID is built into Btrfs now. Just like ZFS.

That means that BTRFS is smaller and cleaner and needs less man-hours to get to production quality.


If only that were true. I'm guessing you don't read the btrfs-devel mailing list. Or you'd realise just how funny your comment is.

And it gets all the features of ZFS (and then some!),


Wow, you are so far out in left field on this, that it's no longer funny. Btrfs is still missing half of the features of ZFS:
single-parity raid (aka raidz1)
dual-parity raid (aka raidz2)
triple-parity raid (aka raidz3)
deduplication
encryption
multiple compression schemes
dataset streaming (zfs send/recv)

There's more, but that's a good start on the ZFS features that Btrfs is currently missing (with no plans for incorporation in the next 6-12 months).

Did I miss anything? I think I just proved you wrong about everything.


Actually, other than some corrections about Theo, you've proven your lack of factual information quite well. ;)
