Specify the maximum number of virtual adapters for this partition profile. You can specify any number from 2 through 65 536.
This number includes the two system-created virtual serial adapters in slots 0 and 1 that allow the Hardware Management Console to access the logical partition.
The higher the maximum number is, the more memory the managed system reserves to manage the virtual adapters, so specify only the number of virtual adapters you are likely to use.
