While you're testing/installing/upgrading to this new release, let's check out the following top 7 cool things about Oracle Solaris 11 Express:
#1: Upgrading From OpenSolaris to Solaris 11 Express is Easy!
In fact, Oracle Solaris 11 Express is the one and only technical successor to Sun's OpenSolaris distribution. While the name, the branding and the licensing changed, the development path didn't. And so, it's actually no surprise that you can upgrade from OpenSolaris 2009.06 to Oracle Solaris 11 Express the same way you would to any other release of OpenSolaris.
The Oracle Solaris 11 Express upgrade process is well-documented and there are two changes compared to the traditional OpenSolaris upgrade process that reflect the branding and licensing changes:
The repository has changed to http://pkg.oracle.com/solaris/release/,
You need to accept the new license by adding
But again, the upgrade documentation will walk you through all the necessary steps.
Notice to Solaris 10 users: While a direct upgrade from Solaris 10 is not supported at this time, you can use the new Oracle Solaris 10 Containers feature to wrap your existing Solaris 10 installation inside a Solaris 11 system, comfortably living in its own container.
#2: Oracle Solaris 11 Express is Production Ready
You heard that right. This is not beta, this is not just a play thing, this is a real OS and you can use it for production, if you have a support contract. Check out Oracle Premier Support Options now.
Of course, Oracle itself uses Solaris 11 Express in production: From countless internal deployments to the Oracle ZFS Storage Appliances, which derive their Firmware out of the Oracle Solaris 11 Express codebase, to Oracle's Exadata Database Machine and Exalogic Elastic Cloud products, which are announced to be powered by Solaris 11 Express.
#3: Oracle Solaris 11 Express is Free for Development and Evaluation
Check out question #14 of the Oracle Solaris 11 Express FAQ Document: "Yes, you may use Oracle Solaris 11 Express for evaluation and development without a support contract under the Oracle Technical Network perpetual license."
A number of people contacted me with the question whether it's free for use as a home server or as a laptop system. My own personal interpretation (and I'm not a license lawyer so please decide this on your own) is that a home server that you use to test/develop stuff falls under this category, as well as a laptop that you use to test Solaris 11 features with.
The rule of thumb is: If you use Solaris 11 Express to make money, you should buy a support contract that gives you a proper license to do so. That's your way to share your profit that you got out of Solaris 11 Express. After all, the Solaris 11 Express development team has rents to pay and kids to feed, and you'll get first-class enterprise-grade support, so your money will be well spent.
#4: Solaris 10 Containers!
With any major release of an OS or other critical piece of software comes a "Gretchenfrage": How can one redesign a major part of the core without breaking backward compatibility?
In the case of Solaris 11 Express, the question becomes: "How can we redesign (read: fix) the Packaging, Install and Patch process without breaking upgradeability?"
The answer is Solaris 10 Containers (BrandZ to the initiated), which allow you to have the cake and eat it too: Migrate your existing Solaris 10 installation into a Container, and host it inside your shiny new Solaris 11 Express installation. This means you can have Solaris 11 Express and keep Solaris 10, too!
This feature is modestly called "Solaris 10 Containers", but it is an incredibly powerful way to effortlessly and risklessly upgrade your existing Solaris 10 installations to Solaris 11 without going through traditional upgrade hassles.
#5: ZFS Encryption!
And here's the other major big thing we've all been waiting for: ZFS Encrypted Datasets. Darren Moffat, the main architect behind this feature, has written a series of blog entries around this feature: Introducing ZFS Crypto in Oracle Solaris 11 Express, Assured delete with ZFS dataset encryption, Having my secured cake and Cloning it too (aka Encryption + Dedup with ZFS) and Choosing a value for the ZFS encryption property.
My home directory on my work laptop is now a nicely encrypted ZFS dataset :).
#6: Lots of Oracle Solaris 11 Express Videos to Watch
To learn more about Oracle Solaris 11 Express, there's a wealth of videos with developers and other cool people explaining key features that Deirdré Straughan has put together. Here's a list of videos available to date:
And those were just the recently released Solaris 11 related videos. There are many, many more videos available on the Oracle Solaris Video blog.

Update (2012-03-19): The links to Sun's blogs have changed from blogs.sun.com to blogs.oracle.com, with the old URLs no longer working. I have therefore updated the URLs and they should now work again.
