are the system firmware and IBM i operating system objects necessary to virtualize the physical
I/O resources to client partitions. The following diagram shows the full solution and its
components:
3.1. Virtual SCSI and Ethernet adapters
IBM i hosting IBM i uses an existing function of the system firmware, or Power Hypervisor: the
capability to create virtual SCSI and Ethernet adapters in a partition. Virtual adapters are created
for each LPAR in the Hardware Management Console (HMC). Virtual SCSI adapters are used for
storage and optical virtualization; virtual Ethernet adapters are used for network virtualization.
Note that using virtual I/O resources from a host partition does not preclude an IBM i client
partition from owning physical hardware. A mix of virtual and physical hardware in the same
partition is supported for IBM i in this environment, by assigning both types of adapters to the
partition in the HMC.
3.2. Storage virtualization
To virtualize integrated disk (SCSI, SAS or SSD) or LUNs from a SAN system to an IBM i client
partition, both HMC and IBM i objects must be created. In the HMC, the minimum required
configuration is:
•
One virtual SCSI server adapter in the host partition
