How many paths to a lun are supported in Windows?
Applies to
- Windows Server
- ONTAP 9
Answer
Windows Server 2008 and Windows Server 2008 R2 support up to:
- Eight buses per adapter
- 128 target IDs per bus
- 255 LUNs per target ID
Windows Server 2012 and later versions of Windows support up to:
- 255 buses per adapter
- 128 target IDs per bus
- 255 LUNs per target ID
Windows officially supports up to 32 paths to a lun.
Adding a device that takes the total path count of the host over 1,024 will cause the paths over 1,024 to not be used and potentially not recognize a new LUN.
