LDoms (Logical Domains)

The BigAdmin LDoms (Logical Domains) hub is a resource for System Administrators to get information pertaining to the LDoms technology in Solaris.

Sun Microsystems' Logical Domains, or LDoms, technology is part of a suite of methodologies for consolidation and resource management that includes Sun Fire Dynamic System Domains and Solaris OS Containers, of which resource control and operating system virtualization are a subset. This technology allows you, the user, to allocate a system's various resources, such as memory, CPUs, and devices, into logical groupings and create multiple, discrete systems, each with their own operating system, resources, and identity within a single computer system.

With the LDoms partitioning technology, you can:

  • Create virtual machines each with their own sub-set of resources
  • Protect & Isolate using hardware + firmware combination



LDoms Technology
  • Each domain is a full virtual machine with a reconfigurable subset of machine resources and its own independent OS
  • Protection and isolation via SPARC hardware and LDoms Hypervisor firmware
  • Each virtual machine appears as independent machine
  • Own kernel, patches, tuning parameters
  • Own user accounts, administrators
  • Own disks
  • Own network interfaces, MAC & IP addresses
  • Start, stop and reboot independently
  • Service domains for I/O

Logical Domains Manager

  • One manager per machine controls hypervisor and all its ldoms
  • Exposes CLI to administrator
  • Maps Logical Domains to physical resources
