1 The DPM Community Proposal

* What is expected? * How many countries would be needed to make it sustainable? * Managing the risks (eg. loss of key developers at CERN) * Areas where the proposal needs more detail - how the community will be managed - how wider support (non-contributing countries) will be handled - specific effort expected - who would sign an MoU? - What effort is already contributed from the community

2 Alternatives to DPM

* dCache * Storm/Lustre * GridFTP on Lustre (no SRM) * Cloud storage * How would we migrate? - How long would it take a site to move to an alternative - What are the risks * Further investigation needed?

3 What could we contribute and on what conditions?

* Tools vs core development - Feedback on review of code base - How ready is DPM-light (plugin architecture) * What is the support load - Average bug rates - DPM development roadmap - Other support 'costs' * Who in GridPP would contribute (will/can they) * What about the LFC? * Other options to support DPM

4 Conclusions
