-- Returns information about the working storage of a gateway. This
-- operation is only supported in the stored volumes gateway type. This
-- operation is deprecated in cached volumes API version (20120630). Use
-- DescribeUploadBuffer instead.
--
-- Working storage is also referred to as upload buffer. You can also use
-- the DescribeUploadBuffer operation to add upload buffer to a stored
-- volume gateway.
--
-- The response includes disk IDs that are configured as working storage,
-- and it includes the amount of working storage allocated and used.
