Ceph

h2. %{color:black}CDS Jewel%

The Ceph Developer Summit for Jewel will occur on 1-2 July, 2015.  This summit is where planning for the upcoming Jewel release will happen, and attendance is (as always) open to all.  If you're interested in Ceph, please join us!  It will be a virtual summit (no travel!) using IRC, etherpad, and the BlueJeans conferencing system.

h3. %{color:gold}Session Goals%

After careful consideration of submitted blueprints, Sage and Patrick have created a schedule that allows time for discussing many of them. These should be interactive discussions, not lectures!  Each session will be moderated by the owner of its associated blueprint, with these goals: 

* Identify a blueprint owner, if necessary

* Discuss the possible ways the blueprint might be implemented

* Identify the necessary work items and record them in the session's etherpad

* Determine whether the work can be completed before the Jewel feature freeze

* Identify interested parties and discuss ownership of work items

h3. Tools

We choose to make this a small, online event so that more people can attend and contribute in a meaningful way without having to disrupt their lives with travel time and cost.  In order to facilitate these virtual discussions, we will all be using a few tools.

*IRC*: We have a special logged IRC channel set up for the summit.  This allows us to deal with housekeeping, make announcements, and interact with attendees who aren't in the video conference.  If you can, please join "#ceph-summit":irc://irc.oftc.net/ceph-summit on irc.oftc.net!

*BlueJeans*: We are using an interactive tool for videoconferencing. Because everyone is able to join, users are muted on entrance, so be sure to unmute if (and only if) you would like to speak.

*Etherpad*: Each session will have an associated etherpad for collaborative note taking during the session. This should allow us to capture work items and other notes during the sessions.

The community team will be hanging out in #ceph during the summit to help if anything goes awry. If you have questions before then, please "contact us":mailto:community@ceph.com.
