A、The Virtual SCSI disks are defined as logical volumes in the Virtual IO Server. The logical volumes appear as real devices (hdisks) in the client partitions. 

B、The Virtual IO adapters are connected to a virtual host bridge. On the Virtual IO Server they are vdisks, on the client partition, the exported disks are visible as virtual disks. 

C、The Virtual SCSI disks are represented in the ODM as a bus device whose parent is sysplanar0. Logical volumes will be assigned to the Virtual IO Server and virtual disks, vdisks, in the client partition. 

D、The Virtual IO adapters are represented as adapter devices with the virtual host bridge as their  parent. On the Virtual IO Server they are vdisks attached to vscsi, on the client partition the exported disks are visible as virtual disks.
