You might want to add additional instances to the system if:
- You want to improve the performance of workflow tasks or user searches.
- You are running out of disk space on one or more instances.
This chapter describes how to create an OVF template to make this process easier. You can configure the OVF template so that by simply deploying and powering on a new virtual machine, a new worker instance automatically joins the HCI system.
Important: Each instance must run a number of essential services. Because of this, each new instance you add counts against your licensed service unit limit.
Note: Hitachi Vantara has qualified HCI systems with up to 16 instances.
