Table Of Contents
If you chose the Express installation and enabled Create defaults in the Data Director Setup wizard, a system
resource bundle and Default resource bundle are created during setup. A Default organization with a Default
database group within that organization is also created, and the Default resource bundle is assigned to the
Default organization.
Resource Assignment for Database Groups
When you create a database group, you assign a resource bundle that specifies the resources for that group.
You cannot assign more than one resource bundle to one database group. Multiple database groups can share
one resource bundle.
When you assign a resource bundle to a database group, you can specify how to allocate each resource.
n
CPU priority or reservation.
n
Memory priority or reservation.
n
Storage allocation.
n
Storage reservation percentage.
n
A network for the database group. You cannot divide the network. You can select only one network when
you create a database group even if several networks are associated with the resource bundle.
If you do not specify the CPU or memory allocation, Data Director sets the reservation to zero but sets
expandable reservations to true. If expandable reservations is set to true, the CPU or memory can expand
beyond the specified value.
Resource Assignment for Databases
A database consumes the resources assigned to its database group.
n
You can specify the number of virtual CPUs, the memory size, and CPU and memory priority for each
database that you create.
n
You cannot specify storage allocation. All databases consume the data and the backup storage allocated
to their parent database group. You can specify the size of data or PITR disk of each database.
n
Each database uses the network assigned to the database group as the DB access network.
vSphere Resource Pools and Data Director
A vSphere resource pool is a logical abstraction for flexible management of CPU and memory resources.You
add CPU and memory resources to Data Director resource bundles by adding a vSphere resource pool to the
bundle.
Data Director has the following types of resource pools.
Resource Pools for
Databases
vSphere administrators create one or more resource pools to enable Data
Director users to create databases. Resource pools for databases require
configuration settings such as DRS and HA enabled, and CPU and memory
limits equal to reservation.
System Resource Pool
There is one system resource pool for one Data Director instance. vSphere
administrators can deploy database virtual machine (DBVM) OVA files into
the system resource pool at any time. The configuration settings for the system
resource pool are different from the configuration settings for database
resource pools. You do not have to enable HA, and CPU, and memory limits
do not have to equal reservations. The reservation must be greater than 0.
