Chapter 7. Virtualization 285
Physical adapters
For the VIOS partitions, planning for physical adapter allocation is important,
because the VIOS provides virtualized access through the physical adapters to
network or disk resources. If availability is a concern for the virtualized
environment, use redundant physical adapters in the VIOS. For network
adapters, you most likely use Etherchannel. For storage adapters, a multipathing
package (for example, an MPIO-PCM or EMC PowerPath) is installed and
configured in the VIOS after the operating system is installed. To further enhance
availability in a virtualized configuration, implement two VIOS servers, both
capable of providing the same network and storage access to the virtual servers
on the Power Systems compute node. The ideal availability configuration
involves redundant physical adapters in each of the two VIOS servers. Because
of hardware requirements in a dual VIOS configuration, a p460 might be the
better choice.
Create a similar document that shows the physical adapter assignments to each
VIOS. With only two or four adapters to be assigned to the virtual servers, the
document is fairly simple.
