About Logical Domains (<strong>LDom</strong>s)
cluster. Using the concept of organization entity, users can now group multiple
such VCS clusters into one organization entity, and reserve <strong>LDom</strong>s on the nodes
of these clusters.
Why do you need <strong>LDom</strong> <strong>Capacity</strong> <strong>Management</strong> <strong>Add</strong>-on?
In a typical datacenter, the task of capacity management for a large number of
physical servers is challenging. The administrator needs a tool that can assist in
<strong>LDom</strong>s provisioning in a pool of physical servers based on the resource
requirements of the <strong>LDom</strong>s and the high availability (HA) requirements of the
pool. The <strong>LDom</strong> <strong>Capacity</strong> <strong>Management</strong> <strong>Add</strong>-on allows the storage administrator
to reserve server space for <strong>LDom</strong>s in advance, and prevents them from
over-subscribing the available server resources.
Note: <strong>LDom</strong> <strong>Capacity</strong> <strong>Management</strong> <strong>Add</strong>-on 4.1 is supported only on Veritas
<strong>Operations</strong> <strong>Manager</strong> 4.0, and later.

About Logical Domains (<strong>LDom</strong>s)
Logical Domains (<strong>LDom</strong>s) is a technology that allocates resources such as
processors, memory, disks, or network devices to logical containers. It manages
these resources as logical domains within the physical host. The resulting <strong>LDom</strong>
has its own operating system, and it manages resources independently.
See “Reserving <strong>LDom</strong>s on clusters of an organization entity” on page 17.
About organization entity
In Veritas <strong>Operations</strong> <strong>Manager</strong>, an organization entity is a business entity of
organization type. It is a collection of servers that have similar characteristics.
The user needs to add the managed hosts to the organizational entity. The
associated clusters are inherited automatically. The clusters are managed by VCS
and you can reserve <strong>LDom</strong>s on these clusters. VCS manages each <strong>LDom</strong> as a
resource or an application, and not as a VCS node. The Veritas <strong>Operations</strong> <strong>Manager</strong>
lets you generate reports and enforce compliance criteria for the organizational
