Delphix is hosting a developer-focused event for OpenZFS. The goal of the event is to foster cross-platform community discussions of OpenZFS work, and to make progress on some of the projects proposed for this community.
 
''We were previously calling this event "OpenZFS Day", but decided to rename it to reflect its target audience of ZFS developers.''

== Location ==
The event will be in the [http://www.delphix.com/company/about-delphix/ Delphix office] in San Francisco:
 
[https://www.google.com/maps/preview#!q=604+Mission+St.+Suite+400%2C+San+Francisco%2C+CA+94105&data=!1m4!1m3!1d26473!2d-122.4224157!3d37.7867658!4m12!2m11!1m10!1s0x80858062b5adcc23%3A0xd7584093492239e6!3m8!1m3!1d12612!2d-122.3926051!3d37.7913156!3m2!1i1024!2i768!4f13.1 604 Mission Street, 4th floor, San Francisco, CA 94105]
 
Use the keypad to call Delphix and you will be buzzed in.  Google maps has pretty good [http://goo.gl/QyUHUj directions].  The easiest way to reach the Delphix SF office is by public transportation.  Transportation options, easiest listed first:
* BART to the Montgomery St. Station + 3 minute walk
* Caltrain to the 4th & King station + 25 minutes walk
* Caltrain to the 4th & King station + bus (routes 10, 30, or 45)
* drive + park in a lot (costs about $25/day e.g. 41 Tehama Street, 509 Howard Street, or 55 Hawthorne Street)
 
=== Speaker Info ===
'''Note: If you are in the room, you are potentially a speaker.''' This will be done in unconference style, so every attendee should come prepared to present or otherwise lead a discussion or session of up to 45 minutes. You can indicate potential topics in the registration table below.
 
Equipment available:
* Projector
* Whiteboard
 
=== Hackathon ===
The goals of the hackathon are:
* to get people working with ZFS engineers from outside their normal circles
* to start work on some of the [[projects]] we'd like to accomplish
Therefore, we should plan to work in small teams of 2-3 engineers.  The team members could be pair-programming, splitting up the work into discrete tasks for each person, or advising / implementing.
 
==== Hackathon ideas ====
''Add your idea and your name below.  Be prepared to explain your idea at the beginning of the hackathon and enlist/entice others to help with it.''
* Userland ioctls: support for send/recv (fd operations over the wire)  [[User:mahrens]]
* larger (1MB) blocksize: shouldn't be too hard if we ignore performance impact [[User:mahrens]]
* dedicated kmem_cache for dedup table entries
* stdin / stdout buffer to improve performance of zfs send and receive
* ZFS mechanism to override devices' reported sector size (512 vs 4k) (alex @ delphix)
* feature flags enhancements for send streams [[User:csiden]]
* set owner of all files within a filesystem with a ZFS property [[User:csiden]]
 
=== Registration ===
We are expecting everyone will be there to contribute/participate.
 
'''The sign up deadline has passed'''.  A few spots are available for late registration.  Mail [mailto:admin@open-zfs.org admin@open-zfs.org] if you would like to attend.
