Figure 3-3 DS8300 LPAR resource allocation

Each storage facility image has access to:

￿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)

3.2.3Storage 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.
