az_cache_duration = 3600	(IntOpt) Cache volume availability zones in memory for the provided duration in seconds
backdoor_port = None	(StrOpt) Enable eventlet backdoor.

extra_capabilities = {}	(StrOpt) User defined capabilities, a JSON formatted string specifying key/value pairs.
max_header_line = 16384	(IntOpt) Maximum line size of message headers to be accepted. max_header_line may need to be increased when using large tokens (typically those generated by the Keystone v3 API with big service catalogs).
osapi_max_limit = 1000	(IntOpt) The maximum number of items that a collection resource returns in a single response
osapi_max_request_body_size = 114688	(IntOpt) Max size for body of a request

osapi_volume_ext_list =	(ListOpt) Specify list of extensions to load when using osapi_volume_extension option with cinder.api.contrib.select_extensions
osapi_volume_extension = ['cinder.api.contrib.standard_extensions']	(MultiStrOpt) osapi volume extension to load
osapi_volume_listen = 0.0.0.0	(StrOpt) IP address on which OpenStack Volume API listens
osapi_volume_listen_port = 8776	(IntOpt) Port on which OpenStack Volume API listens

transfer_api_class = cinder.transfer.api.API	(StrOpt) The full class name of the volume transfer API class
volume_api_class = cinder.volume.api.API	(StrOpt) The full class name of the volume API class to use
volume_name_template = volume-%s	(StrOpt) Template string to be used to generate volume names
volume_number_multiplier = -1.0	(FloatOpt) Multiplier used for weighing volume number. Negative numbers mean to spread vs stack.
volume_transfer_key_length = 16	(IntOpt) The number of characters in the autogenerated auth key.
volume_transfer_salt_length = 8	(IntOpt) The number of characters in the salt.
