Inktank’s Ceph: An Open Source Storage Solution for the Enterprise

Editor’s Note: This profile is part of an ongoing weekly series on Leaders of the Open Cloud in advance of CloudOpen, Aug. 29-31 in San Diego.

Ross Turk InktankLaunched in May, Inktank is one of the newest companies to enter the still very new open source cloud computing industry.  But it’s got a great head start as the enterprise support arm of the Ceph storage system. The one-time doctoral thesis of founder Sage Weil, Ceph has been incubating as an open source project with L.A.-based web hosting company DreamHost over the last eight years.

“The founders and the community realized that in order for companies to adopt Ceph and use it, it needed to have commercial support available,” said Ross Turk, VP of community at Inktank. “The technology created a necessity for the company, instead of a company creating technology to make money.”

That technology is an object, block, and file storage platform, often used to provide storage for virtualization. It has a compatible API to Amazon S3 and Swift, so companies can build on any cloud stack or hypervisor. And it’s massively scalable, Turk said, capable of striping a virtual image across an entire cluster or quickly spinning up a thousand virtual machines, for example.  

“It’s storage that’s built specifically to be elastic and massively scalable,” he said. “Building something that can scale the way Ceph does requires a different mentality than building something that’s merely big.”

Because Ceph is built to run on commodity hardware and across platforms, Inktank developers have been involved in multiple open source cloud projects including OpenStack and CloudStack, as well as working with proprietary vendors.

Leaders of the Open Cloud logo“We believe in choice,” Turk said.  “Linux changed the way the server room runs and cloud technologies are going to do the same thing again.

“It’s essential to make sure the technology that drives that revolution is open, standardized and flexible,” he said.

Inktank is hiring and growing quickly to accommodate its new enterprise focus. And on July 10 it released its “Argonaut” version of Ceph with long-term support, focused on stability and easy deployment for enterprise use.

But it’s also working with integrators, storage manufacturers, service providers and others to expand the Ceph community and institute more governance on the open source project.

“It’s an interesting point in the growth of the community,” Turk said.

LMDE’s “gnome2-frozen” Repository Discontinued

In the latest Update Pack to Linux Mint Debian (UP4) released in March, MATE 1.2 and Cinnamon 1.4 were made available as well as an option called “gnome2-frozen” which allowed users to stick to Gnome 2 and skip the Update Pack altogether.

Moving forward and in preparation for Update Pack 5, this repository is now discontinued.

An rsync archive was made available for users and mirrors interested in acquiring a copy of the content of Update Pack 3. This archive will remain open for a couple of weeks and is available at the following address:

  • rsync://debian.linuxmint.com::gnome2-frozen

This is our last goodbye to Gnome 2, a desktop we enjoyed working with since 2006 and which we can unfortunately no longer provide. Although there are still a few technologies which weren’t ported to newer desktops, we’re really proud of the work done by the MATE team and the results we’re getting with Cinnamon. Desktops like KDE and Xfce have also matured a lot and new solutions such as Shell and Unity provide additional alternatives to users.

The loss of Gnome 2 was a traumatic experience not only for users but for desktop distributions. Most of our focus in Linux Mint 12 and Linux Mint 13 went towards making this transition as smooth as possible. With Linux Mint 14 we’ll see the focus switch back towards iterative development/innovations and incremental improvements. Cinnamon will continue to improve and gain momentum but the focus will switch back to developing tools and improving the Linux Mint desktop experience itself, across all editions.

Make Way for the Software-Defined Data Center

The messaging in VMware’s announcement of its planned acquisition of Nicira offers insight into both the company’s view of the deal and the current state of cloud computing. In essence, without virtualization, cloud computing is an amorphous pipe dream. However, virtualization alone — or of one type or in just one portion of the IT infrastructure — isn’t enough to support truly agile, elastic, efficient and reliable compute clouds.
