TMCNet Interview with Tom Trainer at Cloud Expo

We had a blast last week at Cloud Expo, with lots of customers, users and partners coming by to say hello. TMCnet was kind of enough to interview our in-house storage industry expert, Tom Trainer:

Gluster Joins Calxeda Trailblazer Initiative

Innovative cloud storage provider commits to ecosystem dedicated to working with ARM server innovator to improve datacenter and server efficiency

Sunnyvale, Calif. – June 14, 2011 – Gluster, the leading provider of scale-out, open source storage solutions, today announced it is among the first companies to join the Calxeda Trailblazer Initiative, an industry ecosystem of companies dedicated to improving server and datacenter efficiency. Gluster was selected by Calxeda to be a Trailblazer, and as such, will be first to begin proof of concept testing this fall. For more information, please see the release on the launch of the Calxeda Trailblazer Initiative, issued today.

“As volumes of information increase daily, storage continues to be the holy grail. Gluster’s scale-out NAS approach for cloud and virtual machine environments combined with Calxeda’s scale-out architecture will be a formidable player in all things datacenter storage,” said Barry Evans, CEO, Calxeda. “Collaborating, as we will do with Gluster as an early member of Trailblazer, will enable our two companies to make the datacenter of the future real in the very near term.”

Trailblazer partners will work with Calxeda to accelerate adoption of hyper-efficient servers, creating a rich ecosystem that end users will benefit from by ultimately delivering full systems faster. Since its August 2010 launch, Calxeda has created significant industry interest in its ARM-based servers. With Trailblazer, Calxeda is reacting to demand from customers and partners to get its chips into servers and datacenters, the first step being partner access to early silicon for Proof of Concept testing, expected this Fall. The Calxeda Trailblazer program will comprise a wide variety of industry players, software developers, hardware companies and systems integrators, including Gluster.

“The trend towards low-power and hyper-efficient compute resources matches what we are seeing in the storage market,” said AB Periasamy, founder and CTO, Gluster. “Organizations want to reduce costs associated with compute and storage infrastructure while maximizing performance and we are pleased to be participating in the Calxeda Trailblazer program.”

As a Trailblazer, Calxeda will provide Gluster with early access to hardware, operating system software, tools, applications and joint sales and marketing. Gluster will also receive first updates on valuable benchmarking and technical information, all intended to help both companies – and the entire ecosystem – deliver complete systems to end users faster, improving datacenter efficiency. Powered by Calxeda’s high-performance, low-power ARM chips, these new servers and next generation data centers will help solve the energy consumption crisis, and will significantly increase efficiency and save money for users along the way.

The Future of Cloud Storage talk – Video, Slides and Photos

Our co-founder and CTO, AB Periasamy, made the trek to to present his (and Gluster’s) vision of the future of cloud storage. Like everything else, storage is increasingly decoupled from the physical media that one normally associates with it, ie. disk drives and hardware. While the virtualization of the storage layer might lag the speed that compute power and everything else has been virtualized, things are now proceeding at a very fast pace. It feels good to know that Gluster is at the vanguard of this movement.

Here is video of AB’s presentation:

Monolithic Scale-Out NAS Is Out Of Gas

The cloudwashing that’s running rampant throughout the storage industry has clearly got to stop. My latest observation is that traditional monolithic scale-out NAS vendors are so aggressively selling their offerings for the cloud that their claims are completely out of control.

Please allow me to introduce myself…

As Gluster’s newly-annointed community guy, I wanted to give a big “Hello” to the Gluster community. After a 3-year hiatus from commercial open source projects, it feels great to be back in the saddle. A long, long time ago, in a galaxy far, far away, I was charged with building developer communities (we called them foundries) for Since then, I’ve been involved in a couple of startups, including Hyperic. Most recently, I was at Splunk. As great as that was – and it was pretty great – there was definitely something missing. That something was the good will that comes from empowering anyone with smarts and desire to create things out of the building blocks you gave them. Useful, productive things that power economies, stimulate innovation, and lift others out of poverty. Having dabbled on the other side of the fence for the last three years, I can now say with some authority that this is only possible with open source; everything else falls just short of granting a community the level of control and power they need to really own their involvement.

Of course, Gluster, Inc. is no non-profit, so it doesn’t hurt that giving free software to the world also gives us a competitive advantage in the storage industry. I was intrigued by the co-founders’ belief that the future of storage is in the software, and the industry-wide movement towards clouds and virtualization corroborate this view. The last generation of proprietary software tightly bound to a proprietary hardware layer simply doesn’t make sense in a world where abstraction layers blur where computing resources begin and end. It is now relatively easy to add memory and compute power, but storage is the final frontier for distributed computing. Now, with GlusterFS, we can add petabytes of storage, decoupled from specific devices and blocks for greater elasticity and scalability. Gluster provides high availability by synchronously replicating files locally with our n-Way replication and across large geographic distances with asynchronous Geo-replication, and – most importantly – we do it all elastically. As an added bonus, we give you this without requiring developers to re-write their code. It’s an open source community guy’s dream: rock-solid open source foundation, dynamic user and developer community, cutting edge cloud computing, and adding value for customers and community participants around the world.

I’m here because, frankly, we need to establish a more productive dialogue with our user and developer communities. If there are particular community-related topics you’d like to hear about, let me know! And if there’s anything you would like to see us do (or not do) vis a vis the Gluster community, write about it in the comments below. You can reach me in a myriad of ways:

On Twitter, I’m @johnmark and I often post under the @gluster handle. I’m ‘johnmark’ on our IRC channel, #gluster at, and I post to our Facebook page, too. And finally, if you must send me email, you may contact me at jwalker ‘at’

I look forward to seeing your comments in the space below, and elsewhere. Drop me a line!
