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 a Microsoft Windows Server operating system.
Note: Check your operating system and HBA documentation for limitations
that might be imposed by other driver software.
Table 1. Maximum multipathing configurations
| Object |
Maximum |
Description |
| Volume |
512 (see Note 1). |
The maximum number of volumes that
can be supported by the system for a host that runs a Windows operating
system (per host object). |
| Paths per volume (see Note 2). |
8 |
The maximum number of paths to each volume. The recommended 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, a Windows Server operating system supports submounting drives as directories
within other drives.
- SDDDSM for Windows supports 16 paths per volume, but
the system supports only a maximum of eight paths to support a reasonable
path-failover time.
