#
# == Define: cinder::backend::dellemc_powermax
#
# Setup Cinder to use the Dell EMC PowerMax Driver
# Compatible for multiple backends
#
# == Parameters
#
# [*san_ip*]
# (required) IP address of PowerMax Unisphere.
#
# [*san_login*]
# (required) PowerMax Unisphere user name.
#
# [*san_password*]
# (required) PowerMax Unisphere user password.
#
# [*powermax_array*]
# (required) Serial number of the PowerMax Array.
#
# [*powermax_srp*]
# (required) Storage resource pool on array to use for provisioning.
#
# [*powermax_port_groups*]
# (required) List of port groups.
#
# [*powermax_storage_protocol*]
# (optional) The Storage protocol, iSCSI or FC.
# This will determine
# which Volume Driver will be configured; PowerMaxISCSIDriver or PowerMaxFCDriver.
# Defaults to 'iSCSI'
#
# [*volume_backend_name*]
# (optional) Allows for the volume_backend_name to be separate of $name.
# Defaults to: $name
#
# [*backend_availability_zone*]
# (Optional) Availability zone for this volume backend.
# If not set, the storage_availability_zone option value
# is used as the default for all backends.
# Defaults to $facts['os_service_default'].
#
# [*image_volume_cache_enabled*]
# (Optional) Enable Cinder's image cache function for this backend.
# Defaults to $facts['os_service_default'],
#
# [*image_volume_cache_max_size_gb*]
# (Optional) Max size of the image volume cache for this backend in GB.
# Defaults to $facts['os_service_default'],
#
# [*image_volume_cache_max_count*]
# (Optional) Max number of entries allowed in the image volume cache.
# Defaults to $facts['os_service_default'],
#
# [*reserved_percentage*]
# (Optional) The percentage of backend capacity is reserved.
# Defaults to $facts['os_service_default'].
#
# [*max_over_subscription_ratio*]
# (Optional) Representation of the over subscription ratio when thin
# provisionig is involved.
# Defaults to $facts['os_service_default'].
#
# [*rest_api_connect_timeout*]
# (Optional) Connection timeout value (in seconds) for rest call.
# Defaults to $facts['os_service_default'].
#
# [*rest_api_read_timeout*]
# (Optional) Read timeout value (in seconds) for rest call.
# Defaults to $facts['os_service_default'].
#
# [*manage_volume_type*]
# (Optional) Whether or not manage Cinder Volume type.
# If set to true, a Cinder Volume type will be created
# with volume_backend_name=$volume_backend_name key/value.
# Defaults to false.
#
# [*extra_options*]
# (optional) Hash of extra options to pass to the backend stanza
# Defaults to: {}
# Example :
# { 'dellemc_powermax_backend/param1' => { 'value' => value1 } }#
#
