These are the notes for Tim's talk at OSS BarCamp, held in Dublin on September 19th 2009. Operating System Advocacy...

An Introduction to OpenSolaris pg 2

Doing operating system advocacy is hard. There's a tendancy for two things to happen:

●You come across as the guy in the picture, content that your OS is the best thing in the world and being overly pushy about it ●You end up talking to people like the guy in the picture, who knows he's already running the best OS in the world, and is intending to tell you all about it

Obviously neither situation is good – hopefully in this talk, I'll be able to avoid either of these. Please throw something at me if we start to veer in the wrong direction :-) Solaris 10 & history of OpenSolaris

S10 released in 2004 Why the decision to open source?

An Introduction to OpenSolaris pg 3

Solaris 10 was arguably one of the most important Solaris releases in Sun's history, including some incredible innovations like DTrace, SMF and Zones.

It did a good job of catering to the needs of the existing Solaris install-base, however it wasn't addressing the small developer or student market.

It also wasn't open source, which was becoming a strong selling point of Linux distributions, which were very successful in those markets – Sun used to be strong in those markets, but in recent years had lost focus.

Open sourcing Solaris could address that, and make it easier for Sun to work with their partners. OpenSolaris release

An Introduction to OpenSolaris pg 4

The release of the code was staggered – DTrace was released initially, one of the “crown jewels” in Solaris 10, showing the world we were serious.

The main release of the ON consolidation code happened in June, and over time, as more code was cleared from a legal perspective, it was released. See also: http://blogs.sun.com/jimgris/entry/opensolaris_at_two

As more code gets cleared, it gets released. Otherwise it gets rewritten. Distributions

An Introduction to OpenSolaris pg 5

There's a heap of OpenSolaris distributions, both from Sun and outside, and run the gamut from small, one- man distributions to full commercially supported operating systems.

Sun currently has two OpenSolaris distributions – OpenSolaris, and Solaris Express Community Edition. The latter, closer to the current Solaris 10 tree in terms of install & packaging tools is stopping soon. Platforms

x86/x64 Sparc ARM System Z Power PC

An Introduction to OpenSolaris pg 6

The two main platforms are x86 and sparc – both 32/64 bit for x86 (a single OS image can boot either 32-bit or 64-bit) and 64-bit for sparc.

Show Solaris in a new light Testing ground for new features Install Packaging ZFS 6-month release cycle Became the OpenSolaris distribution The future

An Introduction to OpenSolaris pg 7

Project Indiana was a focal point for several projects that were running inside Sun – exploring a new installer, a new packaging system and changing some of the system defaults to be more familiar to Linux users.

Rather than making the changes in the ongoing Solaris Express distribution, they were made here, targetting the student/developer market. Ultimately Project Indiana became the OpenSolaris distribution from Sun, which is paving the way for the next maj. enterprise- oriented Solaris release.

Some of the features of OpenSolaris. There's lots more detail on each feature in the given links. Features: Storage http://opensolaris.org/os/community/zfs ZFS Combines volume management with a filesystem Hybrid storage pool approach Checksums everything Unlimited snapshots & clones with rollback For “free” - COW nature

An Introduction to OpenSolaris pg 9

ZFS is one of the ground breaking features of OpenSolaris. It's been ported to FreeBSD & NetBSD and there's an ongoing port to Mac OSX.

It integrated into the OpenSolaris code base on 31st Oct. 2005, and was backported to a production-ready Solaris 10 update in June 2006. Features: Storage (cont.) http://opensolaris.org/os/community/storage

An Introduction to OpenSolaris pg 10

Storage on OpenSolaris isn't just about ZFS though - the Storage community is particularly active – lots of interesting technology here. Features: Networking http://opensolaris.org/os/community/networking Crossbow IPFilter NWAM

An Introduction to OpenSolaris pg 11

Crossbow is one of the big networking features in OpenSolaris. It virtualises the network stack, taking advantage of hardware capabilites in your network card where possible.

Crossbow allows one to create virtual nics or switches and set bandwidth limits right down to the individual protocol or network port. Feel like limiting https ?

# flowadm add-flow -l bge0 -a transport=TCP,local_port=443 https-1 # flowadm set-flowprop -p maxbw=500M,priority=high https-1 IPFilter is builtin, and getting more closely integrated with SMF. NWAM makes setting up laptops easy. Features: Desktop http://opensolaris.org/os/community/desktop GNOME 2.26 (nearly 2.28) Time Slider

S3 Suspend/resume Wifi :-)

An Introduction to OpenSolaris pg 12

OpenSolaris bundles a recent version of GNOME. It includes accellerated 3D drivers from Intel and Nvidia meaning we can haz whizzy compiz effects too :-) Time Slider integrates ZFS more closely with the desktop file manager, allowing the user to browse snapshots that are taken periodically. S3 suspend/resume works on supported hardware and there's been a push to get more wifi drivers bundled – a complete list is at http://opensolaris.org/os/community/laptop/wireless/ Features: Virtualisation

An Introduction to OpenSolaris pg 13

OpenSolaris has a range of virtualisation features, each targetting a different use-case. Explore opensolaris.org
