Red Hat Storage Predictions for 2013

Looking through a storage crystal ball, here are our top predictions for storage in 2013. Should these predictions come true, not only will the landscape of the IT industry change, but more importantly, innovation will happen at the pace customers need and not at the pace vendors dictate.

Storage Silos Come Crashing Down!

We predict there will be an emergence of storage solutions that provide a unified approach to procuring, provisioning, and managing enterprise data – solutions that are agnostic to the type of data, such as files, objects, blocks, and semi-structured or unstructured data.

Taxis, Zipcars and Cloud Storage

Ben Golub has a new blog post up, titled Taxis, Zipcars and Cloud Storage. Not sure how those things are related? Well, when having a recent discussion on the topic of what kind of car will we be driving in the year 2020, Ben got this interesting insight:

One person, however, suggested a more novel idea. “The car I will be driving,” he said, “is one that I will not own.” Instead, he argued, we’d all be using rent-by-the-hour cars such as those provided by Zipcars and others. Gas, maintenance, insurance, parking, and other costs would all be taken care of by others.

In other words, the biggest innovation would be in the form of provisioning, management, and ownership, rather than any underlying technology.

As in, forget the ownership society – we’re moving to a rental / timeshare society. Remember mainframe computers? Everything old is new again.

The question is not whether these models are viable, but to what extent. After all, the fact that these types of services are proliferating is a testament to their filling a gap in the market:

There is no question that cloud storage, like Zipcars or other rent-by-the-hour car services such as taxis, has a great deal of utility and a great deal of appeal. However, it is interesting to speculate about the extent to which these services can replace the more traditional user-owned and operated models.

For fun, I compared the price of storing 100 GB in various cloud services for one month to the cost of using on-premise storage. To make the comparison more apples-to-apples, I divided the cost of the on-premise storage by 36, assuming they had a three-year life span.

On the surface, the cloud storage seems ridiculously expensive — as much as 20 times the price of on-premise storage.

And therein lies the rub – is there a place in the world for a service that is, on the surface, more than double the price of its nearest competitor? As Ben goes on to note, the premium you pay is for the flexibility – the ability to buy a service whenever you want, however much you want. There are no permanent costs, and you’ll only pay for the time you use the service. In this context, the taxi cab model is a useful analogy. Obviously, riding everywhere in a cab would be prohibitively expensive, but that’s not how one uses a cab. We don’t know whether cloud storage will “take over the world”, but we do know that there are times when it’s superior to other alternatives, depending on the parameters of a given project. Do you use cloud storage services? What do you think?

Gluster Documentation Links – Now Fixed

Some of you noticed an error resulting from our DNS changeover last Friday, resulting in users finding themselves redirected to the storage portal when attempting to reach the Gluster documentation. I’m happy to announce that this has now been fixed.

All links to Gluster documentation should now go through Update your documentation links to point here.

Additionally, there are new docs for the Red Hat Storage Software Appliance (SSA). From now on, you’ll see new SSA docs appear there, and GlusterFS docs will show up on

Let me know if this doesn’t work as described.

Welcome to Red Hat Storage!

Beginning today, you will have noticed some changes with, beginning with the domain name As you may have already noticed, we now redirect to the newly created Red Hat Storage web site – assuming all the DNS changes have propagated. There you will find everything you need to get started with the Red Hat Storage Software Appliance. Oh! did I mention we also released the first Red Hat Storage product?

The newly re-organized documentation now lives within Red Hat’s documentation for all product families.

And, of course, this blog now redirects from to

One more thing that will change is the URL of the bug tracker. The migration is currently in process, but upon completion, will redirect to Red Hat’s bugzilla page.

If you’re looking for, that site will remain as is. Look for a new wiki, documentation and more coming to the community site very soon.

Our goal is to bring new content and features to our greater community of customers, users and developers as seamlessly as possible. If you experience difficulty locating something, post a comment below, and someone will respond as quickly as possible.

Gluster Community Profile: Louis ‘Semiosis’ Zuckerman

Our 3rd and final community profile features Louis ‘Semiosis’ Zuckerman. Semiosis maintains a repository of GlusterFS binaries for Ubuntu on While he came in 2nd in the contest based on his contributions on our Community Q&A forums, many of you may know him from his participation on #gluster on Freenode.

Louis 'Semiosis' Zuckerman

The following is an exchange I had with him a few weeks ago.

Q&A with Louis Zuckerman

How long have you used GlusterFS?

Since November 2010, glusterfs version 3.1.1.

What was it that led you to try it?

I wanted to move my production network from dedicated hosting to EC2.  The biggest hurdle was figuring out how to replace a hardware RAID array NFS server with EBS storage in the AWS cloud.  I needed more capacity than a single EBS volume, and more performance & reliability than any single-server solution could provide.  I was also constrained by my application’s requirement for a POSIX-compliant mounted filesystem.  After reviewing every distributed filesystem I could find, GlusterFS turned out to be a perfect match for my needs across the board, from its technical capabilities and open source license, to the availability of both community and commercial support.

What should everyone know about your participation in the GlusterFS community (if they don’t know already)

I’m co-maintainer, with Patrick Matthaei, of the Debian project’s GlusterFS packages.  I also independently maintain Ubuntu packages of the latest 3.1, 3.2 & 3.3 series versions of GlusterFS.  I publish these packages to Launchpad PPAs, making both client/server and pure-client binary packages publicly available for Ubuntu i386 and amd64 architectures.

I discovered & solved a bug which prevented mounting local glusterfs volumes at boot on Ubuntu, and contributed the solution (an upstart job) to Gluster for inclusion in future versions.  I also provide Ubuntu packages that include the new upstart job (instead of an initscript) for glusterd in separate PPAs.

I participated in the first Ubuntu Cloud Days event, giving a presentation called “Scaling shared-storage web apps in the cloud with Ubuntu & GlusterFS.”  In this tutorial I introduced glusterfs and outlined the concepts and techniques involved in managing a glusterfs storage cluster, paying special attention to the opportunities & issues which arise specifically from running glusterfs in EC2.

I’m one of the few regulars in the gluster IRC channel with experience running glusterfs in production on either EC2 or Ubuntu, and maybe the only one using them all together.

I’m semiosis on Freenode IRC #gluster, on twitter

Why do you participate in the Gluster community?

When I started using glusterfs there was minimal support for Debian & Ubuntu from Gluster or from the community.  The Debian project’s glusterfs packages were broken and the Ubuntu project’s packages were very outdated.  The official packages for Debian & Ubuntu provided by Gluster were only for amd64 and included the full client/server installation; no i386 or pure-client packages were available.  As a result of this situation, and my need for such packages, I set out to build my own to solve the problem.  Contributing my work back to the community seemed like the right thing to do because if I needed these packages, then others surely did as well.

I participate in the gluster IRC channel because when I was starting out with glusterfs I learned a ton by asking questions there, and also from reading the chat logs, and like to give back in kind.  Last but not least, I enjoy sharing my knowledge & experience, and learn a lot by helping & observing others troubleshoot their glusterfs installations.

What was a Gluster Community Moment ™ that you’ll never forget?

The earliest was when Debian & Ubuntu developer Al Stone (ahs3) appeared in the gluster IRC channel to thank me for my packaging work bringing current versions of glusterfs to the Ubuntu i386 architecture.

Bonus: Other than yourself, who’s your favorite Gluster community member, and why?

I appreciate all of the community members I’ve had the pleasure of speaking with on IRC and would have a hard time choosing a favorite.  Each of us has a unique background & skill set we bring to the community and I enjoy that diversity.  However having said that, if I had to pick one, I would say glusterbot because he’s never wrong.
