Add Compute Nodes to an Existing Duplex System
|
|
==============================================
|
|
|
|
You can add up to 6 compute nodes to an existing Duplex system by following
|
|
the standard procedures for adding compute nodes to a system.

|
|
|
|
Before adding compute nodes to a duplex system, you can either add and
|
|
provision platform RAM and CPU cores on the controllers or reallocate RAM and
|
|
CPU cores from the VMs to the platform.
|
|
|
|
.. xbooklink To add platform RAM and CPU cores on the controllers,
|
|
see |node-doc|: `Changing Hardware Components for a Controller Host <changing-hardware-components-for-a-controller-host>`.
|
|
|
|
The requirements for each added compute node are as follows:

#. Provision the resources.
|
|
|
|
To allocate resources to the controller, update the controller resource
|
|
inventory in |prod-os|. See |node-doc|: |memory-tab| and
|
|
|processor-tab|.
|
|
|
|
#. Add the hosts (compute nodes).
|
|
|
|
Add one or more host entries to the system inventory.

|
|
|
.. xbooklink See |prod|| Installation Overview: `Adding Hosts Using the host-add Command <adding-hosts-using-the-host-add-command>`.
