# HPE SimpliVity configuration

To take advantage of functionality that is specific to HPE SimpliVity (as opposed to core VMware functionality), you need to identify the IP address of each OmniStack appliance in your HPE SimpliVity cluster. In the group_vars/all/vars.yml configuration file, add an array of addresses using the simplivity_appliances variable as shown in the following example:

simplivity_appliances:
- 10.10.173.109
- 10.10.173.110
- 10.10.173.111

If you do not configure this variable, or if the list is empty, you will not be able to take advantage of functionality, described in the remainder of this section, that is specific to HPE SimpliVity. You are only required to have one entry in this list, but HPE recommends that you add multiple entries for the purposes of high availability.

# Automatic provisioning of datastores

Instead of manually creating a datastore for the VMs before starting your deployment, you can now use the playbooks to provision a datastore for you with a particular size. This functionality requires that you configure the simplivity_appliances list as described in the previous section.

If a datastore does not already exist corresponding to the first entry in the datastores list, the playbooks will create a datastore with this name. If the datastore_size variable is specified, the datastore will be created with that size, otherwise it will default to 1024 GiB.

Variable File Description
datastores group_vars/all/vars.yml List of datastores for storing VMs. For example, ['Openshift_HPE']
datastore_size group_vars/all/vars.yml Optional size of datastore, specified in GiB. Defaults to 1024 GiB.

You can take advantage of this functionality when provisioning persistent volumes for Container Storage Interface (CSI). For more information, see the section on Container Storage Interface.
