You can download it here. I must say that it's truly amazing what people behind Nexenta are doing. Just after one year Open Solaris hit the streets they provide almost fully working GNU distribution based on Open Solaris and Debian. I'm really impressed.
"This release of NexentaOS brings to you fully integrated Ubuntu/Dapper Drake userland. Today NexentaOS APT repository contains more than 11,000 Ubuntu/Dapper packages. This number is constantly growing, driven mostly by our industry-strength AutoBuilder."
In addition, Alpha 5 contains:
Sun's Java SE 5.0 Java Development Kit (JDK(tm)) distributed under the new Distributor's License for Java. Available via NexentaOS APT repository.
Live Upgrade. Starting from Alpha 5 we are supporting out-of-APT upgrade of the OpenSolaris core. Use Debian tools to bring your system up to the bleeding edge..
Minimal and full installation, safe mode boot option, removable drive support.
OpenOffice.org 2.0, natively compiled on NexentaOS.
OpenSolaris build #40, non-DEBUG kernel.
GNOME 2.14.x with a bunch of neat features, in particular Application Add/Remove.
KDE 3.5.2 and XFCE 4.3 alternative desktop environments.
And on top of that:
Samba 3.0 (server and client included with InstallCD), iSCSI, ZFS with the latest fixes and updates.
* Graphical .deb Package Installer
* Apache, MySQL, and Perl/Python/PHP
* Rhythmbox Notification
* Better Applications Menu Organization
* Firefox 1.5, Thunderbird 1.5
* Search Results in Nautilus
* New Log Out Dialog
* New polished look and feel
And 11,000 more packages, including the most popular office applications, graphics, and multi-media.
The point is that it's easy to get your code integrated to Open Solaris and you don't have to be a developer - if you are for example a system admin and you find something annoying (or lack of something) in Open Solaris you can easily fix it and share your fix with others. And that's one of the main goals of Open Solaris, isn't it?
There are people afraid that contributing code to Open Solaris could actually mean worse code - fortunately it's NOT the case as even if you are not from Sun you have to submit your changes to code review, ARC, follow coding style in Open Solaris, etc. and fortunately for you (submitters) Sun people will take care of this - you just write changes. That way a high quality of code in Open Solaris is preserved.
Here you can find other bug fixes by non-Sun people into Open Solaris. There are quite a lot of them just after one year Open Solaris is here.
To celebrate PLOSUG formation and Open Solaris anniversary we had a first PLOSUG meeting yesterday.

Just after last Unix Days - Andrzej and I decided to create Polish Open Solaris User Group - PLOSUG. We were supposed to do it few weeks ago but... Anyway here we are. Tomorrow (June 14th) is the one year anniversary of Open Solaris so we think it's a good opportunity to get together and celebrate both: the anniversary and a creation of PLOSUG.
You can find more info about tomorrow meeting on PLOSUG page.
If you are from Poland and want to participate, talk, etc. about Open Solaris and its technologies, and also meet from time to time then please join to us.
PL-OSUG mailing-list is here.
PL-OSUG archives are here.
ps. this entry is in English however we'll mostly talk in Polish on PLOSUG mailing-list I guess.

Last time I tried ZFS on SATA disks and to my surprise - just after 3 days I got few hundreds checksum error - well, that explains a lot. Then it stabilized and now from time to time I see occasional errors.
Sometimes we had to live with some problems for so long without any alternative that we have forgotten about a problem and got accustomed to fsck, some bad files, etc.
I would say that ZFS changes that picture radically.
Thanks to ZFS there's no need to fsck, proper data are returned to applications, no mangled fs entries, etc.
It already save our data :)
ps. I haven't yet seen checksum errors reported by ZFS on SCSI, FC or SAS disks...

To make things worse you can't buy T1000 with a Bronze support - you have to buy Silver at least - but that means quite a cost in a 2nd and 3rd year if you want 3 years "warranty" - I know you get more but sometimes you don't need more and all you need is a simple (cheap) warranty.
IMHO it should be corrected as soon as possible so Niagara servers are treated at least the same way as Opteron servers - 3yrs warranty by default. Bronze support should also be offered (at least it's not possible to buy bronze support for T1000/T2000 here in Poland).

So if you want to use raid-z in your environment first carefully consider your workload and if many raid-z in one pool aren't good solution for you then use different raids offered by ZFS. Fortunately other raids in ZFS are NOT affected that way.
If you need more details then read Roch's blog entry on it.
