  1. SRM - Storage Road Map J Jensen GridPP25 at Ambleside

  2. GridPP Storage and Data Management Group • 70-80 members • Three funded posts (Wahid, Sam, Brian) • 10 different countries • Weekly meetings (Wed. 10:00-10:30) • Core of ~15 attending regularly • You will never be asked to take minutes  • Much stuff done as a group

  3. Group Roles • Operate Infrastructure • Support – troubleshoot, assist • Develop supporting tools • Evaluate middleware/hardware • Share experiences • Make recommendations • Develop “services”

  4. Sharing Experiences • With each other • EgdCachereevalutation • Hadoop, SSD, pcache, ext4 vsxfs • Procurement • With WLCG and NGS • With others (outreach and publications) egHEPiX, CHEP, etc.

  5. Services? • Checking file integrity • Checked with ATLAS • Checking catalogue integrity • Checked with T2K

  6. VO = Value Odded • Most VOs represented via their site(s) • Cf. feedback presentation • ATLAS represented slightly more directly • More demanding on T2s  (space tokens and suchlike) • Is anyone missing? • LCG experiments challenging • Other GridPP experiments are also important!

  7. Information Publishing • … since you asked • Sagarmatha! • Publishing according to InstalledCapacity • More or less • Some rules counterintuitive • Some oddities in the implementations • Improving – slowly

  8. Future • Support diverse VOs • Integrate with NGI? • doing storage (very) differently • Work with (but not just with) WLCG • Red Queen Principle • “Run as fast as you can just to stand still”
