This change addresses a long-standing issue in rST documentation imported from XML.
That import process added backslash escapes in front of various characters. The three
most common being '(', ')', and '_'.
These instances are removed.

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.
partner
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.
The requirements for each added compute node are as follows:
| Compute Nodes | RAM (GB) | CPU Cores |
|---|---|---|
| 1 | +2 | +1 |
| 2 | +4 | +1 |
| 3 | +6 | +2 |
| 4 | +8 | +2 |
Provision the resources.
To allocate resources to the controller, update the controller resource inventory in . See :
Memory Tab <memory-tab>andProcessor Tab <processor-tab>.Add the hosts (compute nodes).
Add one or more host entries to the system inventory.
For more information on Host memory provisioning, see, :
