Multipathing configuration maximums for hosts that run Microsoft Hyper-V operating systems

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.
