򐂰 50 percent of the processors
򐂰 50 percent of the processor memory
򐂰 1 loop of the RIO-G interconnection
򐂰 Up to 16 host adapters (4 I/O drawers with up to 4 host adapters)
򐂰 Up to 320 disk drives (up to 96 TB of capacity)
3.2.3 Storage facility image hardware components
In this section we explain which hardware resources are required to build a storage facility
image.
The management of the resource allocation between LPARs on a pSeries is done via the
Storage Hardware Management Console (S-HMC). Because the DS8300 Model 9A2
provides a fixed split between the two storage facility images, there is no management or
configuration necessary via the S-HMC. The DS8300 comes pre-configured with all required
LPAR resources assigned to either storage facility image.
Figure 3-4 on page 51 shows the split of all available resources between the two storage
facility images. Each storage facility image has 50% of all available resources.
