Understanding the Software Configurations
Again, you use the I/O Domain Creation tool to assign the IB VFs and 10GbE VFs to the I/
O Domains using the resources available in the IB VF and 10GbE VF repositories. However,
because VFs are created on each 10GbE NIC and IB HCA, the VFs assigned to an I/O Domain
will always come from the specific Root Domain that is associated with the 10GbE NIC and IB
HCA cards that contain those VFs.
The number and size of the I/O Domains that you can create depends on several factors,
including the amount of CPU core and memory resources that are available in the CPU and
memory repositories and the amount of CPU core and memory resources that you want to
assign to each I/O Domain. However, while it is useful to know the total amount of resources
are that are parked in the repositories, it does not necessarily translate into the maximum
number of I/O Domains that you can create for your system. In addition, you should not create
an I/O Domain that uses more than one socket's worth of resources.
