4. Cluster file systems distributed locking and cache coherency mechanisms kill performance

5. VM->VMM->FS->File->BD->TCP->Ethernet overhead

8. No distributed locking

9. Sparse disk, snapshots, multipath, link aggregation “for free”

10. CRUSH/Rados data redistribution

11. Heatmaps for caches

12. Low overhead Ethernet Transport

15. Any number of links to any switch

16. Access and Storage roles can be combined

17. Storage nodes export block storage to internal network by id

18. Any block device can be attached to back-end (SAN, iSCSI, etc)

21. Identify type and choose queue

22. Apply Data Protection Policy and set placement hints for each part

23. Set destination storage for each part using CRUSH (Controlled Replication Under Scalable Hashing)

24. Send data to storage nodes

26. 1 virtual disc exported to Linux kernel AoE client (e1.0)

27. N-way mirroring as data protection policy

28. Sparse back-end

29. One node dies at the end

32. Crypto interface

33. CRUSH

34. Multipath

36. Load Balancing

37. Delayed replication

38. Back-end rebalancing

39. Visioning for Network Map

41. Auto Configuration

42. Cache (W+R)
