1 Open Enterprise FileStore Stonehenge: "virtual distributed NS" Stonehenge Marketing

2 Stonehenge at a Glance Enterprise NS Gateway or NT, Unix, Linux, FS Virtualized Storage OpenSource- & Unix-based One dministrator per Geography One System per Company

3 Stonehenge at a Glance clients (users) 1 Petabyte+ hosted data Maximum Redundancy Maximum Security Web-/Serviceprovider riendly DCE-DFS replacement

4 Why Stonehenge was developed Needed 24h 7 storage environment or disk plant Needed to include numerous unrelated divisions Needed to attach oreign production sites Needed easy scalability due to unknown growth Needed online migration rom running environments Didn't want to purchase more MS licences Didn't want to service non-consolidated hardware

5 What Mainz implemented 3000 Users ile storage, Multi-Terabyte Distributed System, accessible rom Hungary & Caliornia Mature core components: Linux, IX, OpenFS Consolidated ~100 NT servers into 2 racks (+ SN disks) Savings in 2002: Licences $ dministration 3-4 Headcounts No Downtime??? $

6 Comparing with IBM NS Gateway NS Gateway Stonehenge OS (Windows 2000 or Unix) NS pplication Useability dd-ons Linux Stonehenge Endpoint OpenFS client NTFS / JFS / proprietary invisible IX Stonehenge utomation OpenFS server JFS (planning GPFS+HSM) SN Storage SN or 7133-SS

7 Server Virtualization included Virtual ile servers across the Linux arm set up in minutes auto-restarted in case o crash auto-rebuilt in case o ailing hardware Linux Stonehenge Endpoint Stonehenge Endpoint OpenFS client OpenFS Stonehenge client Endpoint Stonehenge Endpoint Stonehenge Endpoint OpenFS client OpenFS client OpenFS client Beneits: Maximum redundancy, "always on" Easy scaling No Maintenance windows needed User/Client believes seeing a standard Windows or Unix ileserver

8 Subsystem Virtualization included Storage is transparent Migrate storage-to-storage without service interruption Deine storage space across several subsystems IX Stonehenge utomation OpenFS server JFS Beneits: No maintenance window or storage addition / migration / servicing Optimum usage o latest storage hardware Long-distance (1000km+) async. replication included

9 One System per Company Scale one system accross continents ccess anything rom anywhere Caching (automatic) or Replication (scheduled) WN >128kBit //world/dept/myile Original ile Cached instance Scheduled replica One ile tree, always serving nearest instance o a ile
