The illumos Home Data Center

Dan McDonald on illumos Day.

Many of the features in Illumos are already being exploited in the Enterprise and Cloud settings. Features like ZFS (for flexible, robust storage), Zones (for both lightweight hosts and even full Virtual Machine containment), and Crossbow (network traffic shaping and bandwidth management) can easily be spotted in the wild today.

A combination of all of the above features can be exploited in a home or small-business setting to great effect on a single physical machine. This talk will present a home and a small-business deployment of Illumos which eliminates multiple boxes, and uses rock-solid illumos technology.

Four Years Ago / Today

It’s now November, 2012. I will be 50 at the end of this month. Around the time of my birth, my parents – living in Louisiana – participated in the fight for Civil Rights. Their part was small, but it was not without danger. Others, as we know, paid with their lives.

Four years ago, though racism is far from dead in this country, we saw a black man elected president of the United States. I cried with pride, because it showed then how much America deserved to be called a great nation and a world leader.

I have since been often appalled at the number of my fellow citizens who are apparently mortally offended (or fearful) at what made me so happy. They don’t all dare use the racist words of 50 years ago, but it’s there, in code.

The war for Civil Rights is not over. The war for gay rights has barely begun. And the GOP is trying to roll back women’s rights, also hard-won decades ago. They want it to be “their” world again, a world “safe” for straight white men.

Yes, I feel very strongly about this. I was raised to believe in “liberty and justice for all”, though I knew from an early age that that was a goal not yet achieved.

So, if you’re one of those people trying to turn back the tide of history, I want to hear why you think this is a good idea. Step up. You know who you are. I’m waiting.

DevOps Demystified – An introduction to the ideas that are driving DevOps

Ben Rockwood is Joyent’s Director of Systems Engineering. Ben will speak about adopting the new philosophy of DevOps. It is about more than what tools you use, its about people first, process second, and then and only then tools. In this talk we’ll discuss the heart of DevOps, deconstruct culture, examine the fields of study upon which DevOps ideas are being drawn, and consider just what makes a tool a “DevOps tool”. You’ll get an overview of where DevOps is today and where it is going in the future.

Enhanced OS Virtualization for the Cloud

Joyent’s Jerry Jelinek speaks at illumos Day.

SmartOS is an Illumos-derived distro developed by Joyent as the base OS for their cloud. This presentation focuses on the OS virtualization capabilities of SmartOS and details the extensive
enhancements made to the OS, based on real-world production experience deploying SmartOS in the Joyent cloud.

Why 4K?

George Wilson at ZFS Day

For over 30 years, hard drives have designated the smallest storage location as 512 bytes. In January 2011, all major hard drive manufactures began shipping their hard drive platforms using a new standard called Advanced Format. To aid in the transition, these new hard drives provide a 512 byte emulation mode that allows the drives to advertise themselves as a 512 byte addressable devices. This can severely impact write performance resulting in the need for read-modify-write operations for any misaligned or partial writes that are issued.

The problem is not limited to just physical hardware. Other storage platforms may also provide LUNs (logical unit number) that presents themselves as a 512 byte addressable devices when, in fact, they use a 4K sector size internally. Although ZFS has built-in support for 4K sectors, it has no automatic way of dealing with the lies that the storage devices tell. This talk will focus on the methods that have been developed to work around the lies that hard drive storage platforms tell and will discuss the challenges and drawbacks that come with using 4K sectors.
