# == define: cinder::backend::vxflexos
#
# Configures Cinder to use the Dell EMC VxFlexOS Block Storage driver
# Compatible for multiple backends
#
# === Parameters
#
# [*san_login*]
# (required) Administrative user account name used to access the storage
# system or proxy server.
#
# [*san_password*]
# (required) Password for the administrative user account specified in the
# san_login option.
#
# [*san_ip*]
# (required) The hostname (or IP address) for the storage system or proxy
# server.
#
# [*vxflexos_storage_pools*]
# (String) (required) Storage Pools. Comma separated list of storage pools used to provide volumes.
# Each pool should be specified as a protection_domain_name:storage_pool_name value
#
# [*volume_backend_name*]
# (optional) The name of the cinder::backend::vxflexos_ ressource
# 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 $::os_service_default.
#
# [*vxflexos_allow_migration_during_rebuild*]
# (optional) (Boolean) Allow volume migration during rebuild.
# Defaults to $::os_service_default
#
# [*vxflexos_allow_non_padded_volumes*]
# (optional) (Boolean) Allow volumes to be created in Storage Pools
# when zero padding is disabled.
# Defaults to $::os_service_default
#
# [*vxflexos_max_over_subscription_ratio*]
# (optional) (Floating point) max_over_subscription_ratio setting for the driver.
# Maximum value allowed is 10.0.
# Defaults to $::os_service_default
#
# [*vxflexos_rest_server_port*]
# (optional) (String) The TCP port to use for communication with the storage
# system or proxy.
# Defaults to $::os_service_default
#
# [*vxflexos_round_volume_capacity*]
# (optional) (Boolean) Round volume sizes up to 8GB boundaries. VxFlex OS/ScaleIO
# requires volumes to be sized in multiples of 8GB. If set to False,
# volume creation will fail for volumes not sized properly
# Defaults to $::os_service_default
#
# [*vxflexos_server_api_version*]
# (optional) (String) VxFlex OS/ScaleIO API version. This value should be left as the
# default value unless otherwise instructed by technical support.
#
# [*vxflexos_unmap_volume_before_deletion*]
# (optional) (Boolean) Unmap volumes before deletion.
# Defaults to $::os_service_default
#
# [*san_thin_provision*]
# (optional) (Boolean) Wheater to use thin provisioning or not.
# Defaults to $::os_service_default
#
# [*driver_ssl_cert_verify*]
# (optional) Verify the server certificate
# Defaults to $::os_service_default
#
# [*driver_ssl_cert_path*]
# (optional) Server certificate path.
# Defaults to $::os_service_default
#
# [*manage_volume_type*]
# (optional) Whether or not manage Cinder Volume type.
# If set to true, a Cinder Volume type will be created
# with volume_backend_name=$volume_backend_name key/value.
# Defaults to false.
#
# [*extra_options*]
# (optional) Hash of extra options to pass to the backend stanza
# Defaults to: {}
# Example :
# { 'vxflexos_backend/param1' => { 'value' => value1 } }
#
# === Examples
#
# cinder::backend::vxflexos_ { 'myBackend':
# san_login => 'admin',
# san_password => 'password',
# san_ip => 'vxflexos_.mycorp.com',
# vxflexos_storage_pools => 'domain1:pool1',
# }
