When you configure multipathing on your hosts, you must
consider the maximum supported configuration limits.
Table 1 provides
the configuration maximums for hosts running 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 running the Microsoft Hyper-V operating system| Object |
Maximum |
Description |
|---|
| VDisk |
5121 |
The maximum number of VDisks that can be supported
by the SAN Volume Controller for
a host running the Microsoft Hyper-V
operating system (per host object). |
| Paths per VDisk2 |
8 |
The maximum number of paths to each VDisk. The
suggested number of paths is 4. |
Notes: - You can assign a maximum of 26 individual drive letters to a host
running a Windows® operating
system. However, Windows 2000
Server, Windows Server 2003,
and Windows Server 2008
support submounting drives as directories within other drives.
- SDDDSM for Windows supports
16 paths per VDisk, but the SAN Volume Controller supports
only a maximum of eight paths to support a reasonable path-failover
time.
