Introduction 1-3
With logical partitioning, you can divide computing resources into as many as
three distinct partitions. Partitioning can be used for a variety of reasons, in-
cluding:
•
Consolidation of several different computing requirements into one hard-
ware system, thereby reducing floor space requirements, power consump-
tion, and air conditioning costs. Figure 1–2 shows an example of how an en-
terprise whose computing needs are met by three different systems can ac-
complish the same work with one system (a GS140) using logical partitions.
Logical partitions can be used to run different applications that require dif-
ferent configuration and tuning of the operating system.
•
Increasing the efficiency of an existing system. For example, a facility may
have one particularly I/O intensive (or compute intensive) application and a
variety of other applications without such demands. With partitioning, you
can allocate the resources needed to provide the two separate environments
required. More I/O (or CPU) modules can be allocated to the I/O (or com-
pute) intensive application and the other applications limited to a smaller
set of resources, and both environments run at the same time.
