 - `pi_storage_pool` - (Optional, String) Storage Pool for server deployment; if provided then `pi_affinity_policy` will be ignored; Only valid when you deploy one of the IBM supplied stock images. Storage pool for a custom image (an imported image or an image that is created from a VM capture) defaults to the storage pool the image was created in.
 - `pi_storage_pool_affinity` - (Optional, Boolean) Indicates if all volumes attached to the server must reside in the same storage pool. The default value is `true`. To attach data volumes from a different storage pool (mixed storage) set to `false` and use `pi_volume_attach` resource. Once set to `false`, cannot be set back to `true` unless all volumes attached reside in the same storage type and pool.
 - `pi_storage_type` - (Optional, String) - Storage type for server deployment; If storage type is not provided the storage type will default to `tier3`. To get a list of available storage types, please use the [ibm_pi_storage_types_capacity](https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/data-sources/pi_storage_types_capacity) data source.
