Figure 3-2 DS8300 Model 9A2 - LPAR and storage facility image
The DS8300 series incorporates two eServer p5 570s. We call each of these a processor
complex . Each processor complex supports one or more LPARs. Currently each processor
complex on the DS8300 is divided into two LPARs. An LPAR is a set of resources on a
processor complex that support the execution of an operating system. The storage facility
image is built from a pair of LPARs, one on each processor complex.
Figure 3-2 shows that LPAR01 from processor complex 0 and LPAR11 from processor
complex 1 instantiate storage facility image 1. LPAR02 from processor complex 0 and
LPAR12 from processor complex 1 instantiate the second storage facility image.
3.2.2 DS8300 LPAR implementation
Each storage facility image will use the machine type/model number/serial number of the
DS8300 Model 9A2 base frame. The frame serial number will end with
0 . The last character
of the serial number will be replaced by a number in the range one to eight that uniquely
identifies the DS8000 image. Initially, this character will be a 1 or a 2 , because there are only
two storage facility images available. The serial number is needed to distinguish between the
storage facility images in the GUI, CLI, and for licensing and allocating the licenses between
the storage facility images.
The first release of the LPAR functionality in the DS8300 Model 9A2 provides a split between
the resources in a 50/50 ratio as depicted in Figure 3-3 on page 50.
Important: It is important to understand that an LPAR in a processor complex is not the
same as a storage facility image in the DS8300.
