End to end data integrity. Each block has a checksum stored in its parent block point, not in itself. A ZFS storage pool is a tree of blocks so the whole thing self validating. ZFS by itself can't fix it but it can tell you that data corruption has occured.
If you use raid-z, even across partitions on a single drive, you get self healing. Obviously raid-z is designed for multiple drives and you lose some space/performance and this is a seriously oddball configuration (if it works...I should try it sometime when I have time). It certainly won't help you when your drive fails.

It's the default filesystem for OpenSolaris 2008.5. OpenSolaris 2008.11 should be out next month (hence the .11). They're adding a few things to zfs in .11 if I recall correctly...compression, case insensitivity, etc. And a real CIFS (not Samba) for SMB shares.

So, Sun may have modified their implementation for OpenSolaris just as Apple did, but they sure as hell aren't going to re-invent the wheel on this, but will contribute and accelerate the release of Samba4.
Samba4 is definitely worth the effort and even Microsoft realizes if people are going to go to the trouble of making CIFS available across enterprises, they have to work in heterogenous networks, not the fantasy of just homogeneous networks.

"Served Via CIFS. No, this is not a re-packaged Samba with Solaris-specific tweaks. This is the real deal - a native, fully integrated CIFS server that implements the CIFS/SMB LM 0.12 protocol and MSRPC services. It can run in the simple Workgroup mode, or as a member of a Windows AD domain with the full ability to use a domain controller for conferring access and other rights, including the mapping of AD users to UNIX users (so this means that the ZFS or UFS filesystem that comprises a CIFS share can also be exported via NFS in dissimilar environments.) This makes OpenSolaris a truly viable alternative to Windows Server for high-performance, integrated CIFS share serving. Combined with the filesystem management of ZFS, this new CIFS server feature is very compelling. Have a ZFS filesystem that you need exported to some Windows (or Mac, or Linux) boxes? Just like it was with iSCSI, it?s this simple:
Code:
zfs set sharesmb=on pool/my/fs
You can set additional share parameters, such as its advertised name by replacing ?=on? with other arguments. See the section for the set option in the sharemgr(1m) man page. Management of LM users, groups and server mode are accomplished with the separate smbadm(1M) command. "
I guess I should have been more specific in terms of server vs client but with respect to ZFS the server aspect is the relevant one since if you mount a SMB share on your machine it isn't under ZFS. Which you might have figured out if you weren't so quick to try and score some points on me.
Sun is putting a bit of effort to work in the windows environment between upgrading the SMB shares and better Active Directory support. OpenSolaris 2008.5 was just okay but if they keep this level of advancement every 6 months it should be pretty cool. 2008.11 should be nice for both desktop and small server.
What they need is to get the hell off GNOME. Yes, it would be expensive but looking like Ubuntu doesn't buy them much. On the other hand I was never too impressed with Sun's other desktop efforts so maybe they kinda know the limits of their own DNA.
But if they taken Looking Glass and implemented a Zoomable User Interface (ZUI) that might have gotten them a good user experience with a unique interface. Had Sun picked up Piccolo and run with it, it'd be a lot more impressive than Compiz as a core and seeking to sorta equal OSX. ZUI's seem poised to be the next widespread interaction metaphor. Of course, arguably, they've been "poised" for a few years now with little forward traction or major sponsor. Kinda still lodged in academia. Still though, there are some obvious zoom aspects on the iPhone and with any touch surface.
I do take issue with one thing on their site though. They say RAID is limited to < 12 drives... I have a Dell MD1000 with 15 1TB drives in RAID6 running at work right now.
Othern that looks nifty though, gonna have to poke around to see how they're implementing their system under the hood, maybe raidz (too lazy to hunt through their site or google now :-p)...
That DROBO and drobo share look very neat. We have OSX Server unlimited for 10.5 but have never set it up due to time and learning curve restraints. We just want a big file server with redundancy backup that is a no fuss setup/install.

Pretty amazing little device to be honest, it runs pretty quiet, unless under heavy strain of traffic, its a very Mac like item, and its given me a great deal of peace of mind.
Firewire and USB, so even if Apple pull Firewire from everything, your still covered
I was relying on a 1TB drive (almost choked full) and backups of that on 400GB drives, just a mess of cables really, can't believe its all tucked away on on little device

by reliable we mean?

The Solaris smbfs implementation is a port from the Darwin smbfs implementation, which is Apple Computer's BSD variant used in Mac OS X.
Hate to shock you, but Darwin's smbfs is a port of Samba3.
Darwin's next version will be a port of Samba4.
If I check out Darwin: http://www.opensource.apple.com/darwinsource/Current/
I can get the samba port in Darwin.
The Samba4 project will do all the heavy lifting, and does get code back from Sun and Apple.

How about something that users really want, like resolution independence?
How is that something that users really want?
www.drobo.com get one, should change your life
we just got one - pretty darn nifty...

i want it.
I want I want

Don't get me wrong, I want too,
BTW "useless" ?? how much storage do you need?
