  20. VMFS:
    Volumes per host
    256
  21. VMFS:
    Hosts per volume
    64
  22. VMFS:
    Powered‐on virtual machines per VMFS volume
    2048
  23. VMFS3:
    Volume size
    • 64TB
    • For VMFS3 volumes with 1MB block size, the maximum is 50TB.
  24. VMFS3:
    Raw device mapping size (virtual compatibility)
    2TB minus 512 bytes
  25. VMFS3:
    Raw Device Mapping size (physical compatibility)
    • 2TB minus 512 bytes
    • If the presented LUN is greater than 2TB.
  26. VMFS3:
    Block size
    8MB
  27. VMFS3:
    File size (1MB block size)
    256GB
  28. VMFS3
    File size (2MB block size)
    512GB
  29. VMFS3:
    File size (4MB block size)
    1TB
  30. VMFS3:
    File size (8MB block size)
    2TB minus 512 bytes
  31. VMFS3:
    Files per volume
    Approximately 30,720
  32. VMFS5:
    Volume size
    • 64TB
    • The actual maximum will depend on the RAID controller or adapter driver that is being used. Contactyour vendor to find the maximums.
  33. VMFS5:
    Raw Device Mapping size (virtual compatibility)
    2TB minus 512 bytes
  34. VMFS5:
    Raw Device Mapping size (physical compatibility)
    64TB
  35. VMFS5:
    Block size
    • 1MB
    • 1MB is default block size. Upgraded VMFS5 volumes will inherit the VMFS3 block size value.
  36. VMFS5:
    File size
    • 2TB minus 512 bytes
    • Maximum file size for upgraded VMFS5 is 2TB minus 512 bytes, irrespective of the file‐system blocksize.
