About Logical Domains Software
Logical Domains software enables you to allocate the system resources of your
server (such as a boot environment, CPUs, memory, and I/O devices) into logical
domains. By using a logical domains environment, you can increase resource usage,
improve scaling, and gain greater control of security and isolation.
LDoms software enables you to create and manage as many as 128 logical domains,
depending on the hardware configuration of the server on which the Logical
Domains Manager has been installed. You can virtualize resources and define
network, storage, and other I/O devices as services that can be shared between
domains.
