and a brief history of UNIX

History of UNIX? (no)

These are not operating systems.These are distributions of Linux.

Linux isn’t (quite) UNIX.

Linux friendlier

Saturday, June 1, 13

The stage was set...

• 2005: Solaris 10... and OpenSolaris• x86_64 support

• Trusted Extensions

• iSCSI

• Zones (Linux branded zones)

• Crossbow (network virtualization)

• ZFS, then boot, then root, then dedup

• Xen domU support

• fast reboot

Then the unthinkable happened.

• Sun decided that Solaris was a loss-leader

• To compete, go open (harder that it sounds)

• Started with DTrace & ended with OpenSolaris

Saturday, June 1, 13

Ended...

• It ended with OpenSolaris...

• Sun sold to Oracle and...

Kicked Butt,Had Fun,

Didn’t Cheat,Loved Our Customers,

Changed Computing Forever

Interestingly...

Funny enough Oracle decidedto bother having a Solaris 11... good for them.

The rest of us were promised an open future...

and we got Illumos.

Illumos

We reject: kings, presidents and voting.We believe in: rough consensus and running code.

- David D. Clark

Innovation...

• ZFS multi-vendor collaboration (feature flags in the ZFS SPA)

• ZFS + refration (to track compression)

• ZFS + estimated send/recv times

• ZFS I/O throttling across zones

• UNMAP on STMF (efficient ZFS-backed iSCSI LUNs)

• DTrace USDT provider reaping (huge win for Apache and Postgres)

• DTrace + CTF-aware print()

• TCP accept filters and initial congestion window API.

• KVM support

OmniTI stepped into the ring.

Saturday, June 1, 13

OmniOS

• IPS packaging system

• The core OS contains only the packages required to build the core OS.

• with a few exceptions: (zsh, screen, tmux, etc.)

• ZFS-based network installer: Kayak

• Rigorous 6 month release cycles w/ a 2 year long tail.

• Because core is tiny, we encourage a layered-cake approach

• internals are kept current.

• ideal for building appliances.

• Rule: keep your shit to yourself.

• Available on EC2.
