Required hardware components to build a storage image
When you build a storage image, you need to consider your I/O resources, the
processor and memory allocations, and the RIO-G interconnect separation.
The Hardware Management Console (HMC) manages the resource allocation on a
System p host between LPARs. However, the DS8300 comes preconfigured with all
required LPAR resources assigned to either storage image.
Figure 9 shows the split of all available resources between the two storage images.
Each storage image has 50% of all available resources.
I/O resources
The I/O resources that are required for a storage image consist of various
components.
For one storage image, the following hardware resources are required:
v 2 SCSI controllers with 2 disk drives each
v 2 Ethernet ports (to communicate with the HMC)
v 1 Thin Device Media Bay (for example, a CD or a DVD which can be shared
between the LPARs)
Each
storage image has two physical disk drives in each processor complex. Each
disk drive contains three logical volumes, the boot volume and two logical
volumes for the memory save dump function. These three logical volumes are
