Cloud Filesystem HekaFS
Jeff Darcy
Modern open-source distributed filesystems make it possible to provide
file services at a scale and level of availability that's finally
competitive with proprietary options. What they don't do - yet - is
enable secure sharing of those resources between multiple user bases
or organizations who pay for them. This talk will focus on how
GlusterFS works to solve the first set of problems, and how HekaFS -
which is based on GlusterFS - is solving the second. If you're tired
of having to deal with umpteen departmental file servers, each
configured differently, this approach might provide some relief.
Jeff Darcy has been working with network, cluster, and distributed
filesystems for about twenty years - since DECnet was still relevant
and NFSv2 was new. Since then he has gained scars from EMC's MPFS (for
which he was one of the initial developers), Lustre, and GlusterFS. He
is currently at Red Hat, where he's the project lead for HekaFS and
all-around "cloud storage" expert.

Converged Networks, Voice / Video / Storage / Data
Ryan Sutton
How do you keep everything running smoothly while giving technologies
that require low or constant latency what they need and still be able
to watch that dog skateboarding on YouTube. Will discuss how Quality
of Service (QoS) works on both Layer 2 and Layer 3 devices and why you
probably need both. How should traffic be tagged and retagged with
policy decisions. If time permits we may even have some time to go
into why net neutrality isn't as cut and dry as you may think.
Technical details will be based off of Cisco devices but most concepts
will translate to any modern equipment.
Our speaker, Ryan Sutton, is a Systems Engineer at a local Gold
Certified Cisco Partner. Ryan specializes in large scale Routing and
Switching, Voice, and Data Center designs and implementations. His
solutions often include interworking between multiple networking
vendors and technologies. Current projects include sub-second core
convergence, and multi-city/multi-vendor VoIP installations.

Ruby: More Batteries, Fewer Brackets
Aaron D. Ball
Ruby may be most familiar as the language behind the Rails web
framework, and Perl as the "Swiss Army chainsaw" that no sysadmin can
live without, but they have a lot more in common than you might
think. Ruby comes out of the box with a great set of sysadmin tools,
from text processing to Unix system interfaces to TCP servers, and has
a syntax about as terse as Perl but with object-oriented and
functional-programming idioms that make your code easier to write and
understand. Whether you're new to scripting or you've been typing line
noise since 1987, this talk will show you another way.

Automating Inventory, Deployment and Configuration of Your Windows Infrastructure
Dan Stolts
Like most IT professionals, you are an administrator in a
heterogeneous environment. You have a myriad of tools to inventory,
deploy and configure your Unix/Linux machines but how do you do this
for the rest of your machines? Come to this session to learn about the
tools you must have in your toolbox to inventory, deploy, and remotely
configure your windows desktops and servers. We will discuss the free
tools as well as the top of the line fully automatable solutions
available by Microsoft.
Dan Stolts is a technology specialist with more than 24 years in the
industry. He is proficient with many Microsoft products especially
those in the server area and holds many certifications including MCT,
MCITP, MCSE, TS, etc. Dan is currently specializing in Systems
Management and Security and is also very passionate about
virtualization technologies. Dan is and has been a very active member
of the community. He is the current president of Boston User Groups.

The Path to Senior Sysadmin
Adam Moskowitz
Being a senior system administrator is about more than knowing all the
options to mount(8) or that modprobe is what's used to replace that
buggy kernel module with the latest version. Rather, a good senior
sysadmin will have a wide knowledge of relevant technical topics,
in-depth knowledge of one or more technologies, good interpersonal
skills, and the ability to manage "problem users" and will be
comfortable making presentations to and negotiating with mid- and
upper-level management. This talk will cover the skills a senior
sysadmin needs and why they are necessary and will provide some
suggestions for how to acquire these skills.
For nearly one-third of his sysadmin career, Adam Moskowitz held
titles such as Senior System Administrator, System Architect, and IT
Manager. Despite having returned to his roots as a programmer, Adam
remains active in the sysadmin community, including running the LISA
Advanced Topics Workshop and serving on the LOPSA Leadership
Committee. He claims he does all of this only to support his hobby

How Splunk manages our Junk
Jim Donn and Tim Hartmann
As environments grow and systems become more complex, building and
managing a usable centralized logging infrastructure can be a daunting
task. In this talk, we will walk through our real-life experiences
implementing Splunk as our centrali zed logging infrastructure for our
Network, Systems, Security, and Application teams. Over the past three
years, we have had to change our strategies and architecture to
account for organic customer growth, changes in team requirements, and
evolutions in technology.

Using MySQLtuner 2.0 to monitor and improve mysql performance
Sheeri K. Cabral
With help from Major Hayden, mysqltuner's original author, Sheeri
K. Cabral of the Pythian Group has modified mysqltuner to be more
comprehensive, to output information and to have a "spreadsheet" mode
where the results of mysqltuner are outputted as a single column, so
that you can easily compare subsequent runs of the modified
mysqltuner -- for example, running it monthly or weekly to see how
performance is progressing (or degrading). There is also a truly
offline mode that requires no database connectivity where files
containing the output of SHOW GLOBAL STATUS and SHOW GLOBAL VARIABLES
are used. This talk will go through how the the modified mysqltuner
works including how easy it is to change what is checked and the
thresholds, so that you can easily do one-off sanity checks as well as
regular monitoring.
Sheeri K. Cabral (The Pythian Group) is a noted MySQL community activist who recently wrote The MySQL Administrator's Bible.
Keep up with her MySQL writings at http://www.pythian.com/news/author/sheeri/.
