A Look at the Ceph Cookbook

“Ceph is awesome and so is its community” and last year Packt Publishing and Karan Singh from community came up with very first book on Ceph titled “Learning Ceph“.

The overwhelming response to the first book + maturity and popularity of Ceph becomes the base for the next title on Ceph, “Ceph Cookbook“. Author and publisher together has spent several months to produce 326 pages quality content on Ceph including 100 ready to use recipes. And here is the deal, you will get 50% discount on both these books by using this discount code ceph-50 while purchasing the eBook online at packtpub.com. This offer is valid till 31Dec 2016.

When Ceph was originally designed a decade ago, the concept was that “intelligent” disk drives with some modest processing capability could store objects instead of blocks and take an active role in replicating, migrating, or repairing data within the system.  In contrast to conventional disk drives, a smart object-based drive could coordinate with other drives in the system in a peer-to-peer fashion to build a more scalable storage system.

Today an ethernet-attached hard disk drive from WDLabs is making this architecture a reality. WDLabs has assembled over 500 drives from the early production line and assembled them into a 4 PB (3.6 PiB) Ceph cluster running Jewel and the prototype BlueStore storage backend.  WDLabs has been working on validating the need to apply an open source compute environment within the storage device and is now beginning to understand the use cases as thought leaders such as Red Hat work with the early units.  This test seeks to demonstrate that the second generation converged microserver has become a viable solution for distributed storage use cases like Ceph. Building an open platform that can run open source software is a key underpinning of the concept.

The Ceph project would like to congratulate the following students on their acceptance to the 2016 Google Summer of Code program, and the Ceph project:

Student Project
Shehbaz Jaffer BlueStore
Victor Araujo End-to-end Performance Visualization
Aburudha Bose Improve Overall Python Infrastructure
Zhao Junwang Over-the-wire Encryption Support
Oleh Prypin Python 3 Support for Ceph

These five students represent the best of the almost 70 project submissions that we fielded from students around the world. For those not familiar with the Google Summer of Code program, this means that Google will generously fund these students during their summer work.

Thanks to everyone who applied this year, the selection process was made very challenging by the number of highly qualified applicants. We look forward to mentoring students to a successful summer of coding and Open Source, both this year and in the years to come.

v10.2.0 Jewel released

This major release of Ceph will be the foundation for the next long-term stable release. There have been many major changes since the Infernalis (9.2.x) and Hammer (0.94.x) releases, and the upgrade process is non-trivial. Please read these release notes carefully.

v10.0.4 released

This is the fourth and last development release before Jewel. The next release will be a release candidate with the final set of features. Big items include RGW static website support, librbd journal framework, fixed mon sync of config-key data, C++11 updates, and bluestore/kstore.

Note that, due to general developer busyness, we aren’t building official release packages for this dev release. You can fetch autobuilt gitbuilder packages from the usual location (http://gitbuilder.ceph.com).
