  1. Merging the Storage Interfaces and I/O Benchmarking WGs Wahid Bhimji, Dirk Duellmann and other members of the working groups

  2. Storage Interfaces and I/O Benchmarking WGs • 19 June 2012 MB created 3 storage working groups: • Following on from Storage and Data TEG recommendations • I/O Benchmarking; Storage [Management] Interfaces (SI); Federation. • Federation WG presented a “final report” in Feb GDB. • SI and Benchmarking presented interim ones in Mar GDB. • SI and Benchmarking groups progressing well (see GDB): • Coordinate existing activity within VOs / developers. • Neither activity will end soon: continuing need to stay engaged, monitor and ensure interoperability.

  3. Rationale for merger of groups and for wider mandate • SI and Benchmarking overlap in topics and personnel: • Almost all meetings of the groups so far have been “joint”. • Wider topics being discussed such as dataaccessinterfaces: • Areas with TEG recommendations that need following up on. • Affect same group of people - so want to avoid having separate meetings on these. • Overlap with the topics of these Working Groups – but not technically in their original mandate • Increase interest to members (e.g. CMS) who have less need for a SRM related discussion. • Current activities allow time for discussion on these topics.

  4. Propose WLCG Data/Storage Working Group (This merger agreed by existing Working Group chairs and members themselves ) • Initial work-streams for current activities of Storage Interfaces and Benchmarking: could continue with their current mandate and timescales – have joint meetings. • Group also mandated to follow-up on other TEG recommendations: • According to their importance – and if not being followed elsewhere. • Same goals as current groups: leveraging existing activities; ensuring coordination. • Group is long term/ ongoing : however each work-stream has finite timescale: • A new work-stream would provide its own motivation, mandate and timescales. • Group regularly update a standing milestone list and give regular joint reports at GDB. • Initial additional activities to be presented to next GDB (possible areas attached). • Once direction clear within a work-stream -> pass action to WLCG ops WG. • Core membership as currently – with ALICE involvement: • Involve other experts as appropriate (as with current WGs).
