Gluster Community Adds New Members Citrix, Harvard FASRC and Expands Governing Board
Citrix, Harvard University FASRC and long-time contributors join the Gluster Community Board to drive the direction of open software-defined storage

February 5, 2014 – The Gluster Community, the leading community for open software-defined storage, announced today two new organizations have signed letters of intent to join: Citrix, Inc. and Harvard University's Faculty of Arts and Science Research Computing (FASRC) group. This marks the third major expansion of the Gluster Community in governance and projects since mid-2013. Downloads of GlusterFS per month have tripled since the beginning of 2013, and traffic to has increased by over 50% over the previous year. There are now 45 projects on the Gluster Forge and over 200 developers, with integrations either completed or in the works for OpenStack Swift, CloudStack, OpenStack Cinder, Ganeti, Archipelago, Xen, QEMU/KVM, Ganesha, the Java platform, and SAMBA, with more to come in 2014.

Citrix and FASRC will be represented by Mark Hinkle, Senior Director of Open Source Solutions, and James Cuff, Assistant Dean for Research Computing, respectively, joining two individual contributors: Anond Avati, Lead GlusterFS Architect, and Theron Conrey, a contributing speaker, blogger and leading advocate for converged infrastructure. Rounding out the Gluster Community Board are Xavier Hernandez (DataLab); Marc Holmes (Hortonworks), Vin Sharma (Intel), Jim Zemlin (The Linux Foundation), Keisuke Takahashi (NTTPC), Lance Albertson (The Open Source Lab at Oregon State University), John Mark Walker (Red Hat), Louis Zuckerman, Joe Julian, and David Nalley.


Citrix has become a major innovator in the cloud and virtualization markets. They will drive ongoing efforts to integrate GlusterFS with CloudStack ( and the Xen hypervisor. Citrix is also sponsoring Gluster Community events, including a Gluster Cloud Night at their facility in Santa Clara, California on March 18.

Open Matters

Posted by on in Open Source

This is my first post here at Open@Citrix, so I thought I'd start with an introduction and a story about openness. 

Who is this guy: My name is Lars Kurth and am the community manager for the Xen Project; more recently I have also been elected to be the chairman of the Xen Project Advisory Board.

My mission: help the Xen Project do well and prosper!

My background: a lot of different things. My first contact with the open source community took place in 1997 when I worked on various parts of the ARM toolchain - that is compilers, debuggers and instruction set simulators. This set in motion a chain of events that led to a passion for open source, building communities and above all people. Of course technology always was a passion of mine. I worked in a lot of different industries: parallel computing - I was involved in designing development tools for the Eureka Prometheus Project (the largest R&D project ever in the field of driverless cars), semiconductors, mobile and now the cloud industry. I did loads of tools and infrastructure work for ARM, Symbian and Nokia and my journey eventually led me to look after the Xen Project. I also happen to work for Citrix, in the newly formed Open Source Solutions team.

My other passions: travelling to weird and wonderful places, gardening and growing orchids. My favourite weird places: Socotra and Roraima. My favourite orchids: Neomoorea irrorata and Arachnis flos-aeris insignis.

Since my last post on the analysis of the CloudStack community, we have graduated and became a top-level project. It's about time to give an update on what can be seen as a metric of the health of our community.

All the data presented is based on the analysis of the mailing lists, the data is publicly accessible, I have used it previously, just when we graduated March 22nd, in January and back in November when I did some social network analysis. This study was inspired by John Jiang, now working at Eucalyptus, you can read his analysis, note that he moved it to the Eucalyptus website.

Methodology: As explained in previous posts, a Contributor is considered as someone who sent an email to one of the CloudStack mailing lists. This is not to be confused with a Committer which at the ASF is meant to represent someone with write access to the code. Not all code contributors have write access. I identify Companies as the email domain used by the Contributors. This is because Contributors are none-affiliated in the ASF. Obviously it has some limitations as email domains such as can represent different companies. All emails are loaded in a mongodb database and queries are performed to extract the plots that you will see below. We currently have seven mailing lists of varying traffic: announce, users, users-cn, dev, marketing, commits, issues. Note that all JIRA emails are now sent to the issues list. Subscription to these lists and number of messages last month is as follows:

* dev@ 609 subs / ~2600 msgs in Apr
* users@ 782 subs / ~800 msgs in Apr
* issues@ 109 subs / ~2400 msgs in Apr
* commits@ 166 subs / ~3300 msgs in Apr
* marketing@ 85 subs / ~260 msg in Apr
* users-cn@ ~300 subs / ~260 msgs in Apr

Contributors: The plots below show the number of contributors per month since we became an ASF project as well as an accumulation to date. Comparison with traffic prior to joining ASF can be seen in the previous posts. The number of monthly contributors in dev is reaching 225 , while the number of monthly contributors in users is reaching 175. Most notable is that the number of contributors in the users list seem to be closing on the number of contributors in dev. It may indicate a stabilization of the number of developers and an increase in the user base. The accumulation on both lists is now over 500. A comparison of both contributor sets gives us an estimate of 806 for the entire CloudStack community. Of course this does not include people who may only participate in the marketing or announce list, but they are much lower traffic lists. It also does not include participants in the Chinese user lists. This will be in the next post hopefully. From the subscription data listed above you can also see that we have roughly a 30% activity ratio, meaning that 1/3 of the subscribers actually send emails to the lists. Difficult to know if this is a good or bad number, one would need to compare with other ASF projects.

What Do You Want From a CloudStack Preso?

Posted by on in Cloud News

This weekend, I’m heading to Los Angeles for The Eleventh Annual Southern California Linux Expo and then to Portland, Ore. for ApacheCon NA 2013. Why? Well, other than the fact they’re fantastic events, I’m going to spread the word about Apache CloudStack, and have time to meet with other folks who work on CloudStack.

Part of that is giving presentations. I’m speaking on Sunday, February 24th at SCALE, and on Tuesday, February 26th at ApacheCon.

The talks are at an introductory level – not an “I don’t know what cloud is” level, but an “I’ve never deployed an IaaS before” level. (Or perhaps a “I deployed an IaaS and it wasn’t what I hoped it would be, what’s different about CloudStack?” level.)

My question is: What do you want to know about CloudStack? I’d like to make sure the presentations are hitting the points that people care about, and not spending time on things they don’t care about.

Things that are covered now:

Citrix supports the open source community via developer support and evangeslism. We have a number of developers and evangelists that participate actively in the open source community in Apache Cloudstack, OpenDaylight, Xen Project and XenServer. We also conduct educational activities via the Build A Cloud events held all over the world.
