---+ Indico Page

Slowly, but surely, we're moving information from this page and into indico: https://indico.cern.ch/conferenceDisplay.py?confId=165687.

This page is a scratch-pad: consider the indico link authoritative.

Doodle poll for attendance: http://www.doodle.com/bdxer4hw2znmct64

At NIKHEF, starting at 10AM on Tuesday.

(Meeting rooms arranged by Jeff Templon)

Tuesday:
   * all day: Storage Management / Data Management TEG meeting H.331 @ Nikhef.  Estimate 50 people

Wednesday:
   * all day: Storage Management / Data Management TEG meeting H.331 @ Nikhef.  Estimate 50 people

We will organize a dinner Tuesday night; to get more accurate count, we will be asking participants to email the co-chairs Tuesday morning if they'd like to come.

---+ Meeting Goals
Aim for agreement on material that can be used to compose:
   1 Assessment of current situation. 
   1 Needs for (and possible changes in) next 2 to 5 years; 

---+ Scheduling
It seems like this motivates a open (but focussed) discussion rather than a series of talks.  We will try to divide into eight 90-120 minute sessions over the two days.

Sessions could be under each of the topics we have identified so far. 

Joint sessions (perhaps in time order):
   1 Discussion of document to produce.
   1 DM3: Federations; + DM2 : Data placement ?
   1 SM4: SRM and Clouds
   1 DM4: WAN Protools / DM5 : FTS
   1 SM6 / DM6 : Security and Access Control 
   1 DM10 : Management of Catalogues
   1 SM3: Separation of Disk and Tape
   1 SM7: Management and operation of storage at sites (monitoring, performance).
      * Monitoring.
      * Storage I/O /  SM5 : LAN Protocols
      * SM2: Requirements for future storage and how it will evolve.  What kind of disks can be expected?  What directions do we see industry going?
   1 Organization and writing assignments for the Storage Management report.

Things for the document(s), but maybe not enough for a session?
   1 DM1:  Review of Demonstrators from Last Amsterdam Workshop
   1 DM7: ROOT, PROOF, POOL

Perhaps apart from SM7, its seems like people from both groups will be interested in both?  Particularly, experiments may be hard-pressed to have all their representatives join both.

Decisions:
   * *Decision point*: Could we make all sessions joint and use the alternate room as a break-out for group discussions?  Sounds like there is agreement "yes"
   * Would like to go in the direction of
   * We have formal input from the experiments.  This will serve as a mechanism to get input from the sites and middleware; more of a starting point, slightly less formal.
      * The F2F will serve as a way to "anchor" the input from the sites and middleware.  For those that haven't been able to contribute yet,this is their chance to start participating.

In terms of Pre-meeting work: 
   1 Do we need to agree the topics we have listed in a meeting?  I am conscious we never really did that?
      * *From BB*: Would be useful to link back to the master topic list.
   1 Each discussion will need a "leader" and an "enforcer": the leader will be responsible for kicking-off the discussion, and the enforcer will be responsible for keeping it on topic.
      * Each discussion will need an introduction - ideally capturing what we have already learnt from experiment answers and twiki responses. 
      * Intros could be done by the chair - split among the 4 of us it need only be 2 each.  Alternatively we could ask some particular people to digest and uncover a possible view as to:
         * The description of the topic itself (as they see it);
         * Its state of play
         * Where things need to go
         * What might go wrong.
         * and identifying what unanswered questions stand in the way of us.
   1 We need to setup a "framework" for each session - needs to stay on topic, free to do what format they want (discussion-based, pen-and-paper, presentation, etc).
