Logical Domains Software
SPARC Enterprise servers support the Logical Domains (LDoms) 1.0.2 software that
is used to create and manage logical domains. The software comprises LDoms-
enabling code in the Solaris 10 11/06 OS, LDoms-enabling code in System Firmware
6.4, and the Logical Domains Manager, which is the command-line interface.

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.
