When you configure multipathing on your hosts, you must
consider the maximum supported configuration limits.
Table 1 provides the configuration maximums for hosts that run the
Microsoft Hyper-V operating system.
Note: Check your operating system
and HBA documentation for limitations that might be imposed by other
driver software.
Table 1. Configuration maximums for hosts that run the Microsoft Hyper-V
operating system
Object |
Maximum |
Description |
Volume |
5121 |
The maximum number of volumes that
can be supported by the system for a host that is running the Microsoft
Hyper-V operating system (per host object). |
Paths per volume2 |
8 |
The maximum number of paths to each volume. The suggested number of paths is four. |
Notes:
- You can assign a maximum of 26 individual drive letters to a host
that runs a Windows operating system. However, Windows Server 2008
supports submounting drives as directories within other drives.
- SDDDSM for Windows supports 16 paths per volume, but
the Lenovo Storage V series system supports only a maximum of eight paths to support a
reasonable path-failover time.
