Constructor Details

#initialize(size_in_gb:, volume_type:, iops: nil, throughput: nil) ⇒ VolumeSpecificationProperty

Returns a new instance of VolumeSpecificationProperty.

Parameters:

  • size_in_gb (Numeric) —

    The volume size, in gibibytes (GiB).

  • volume_type (String) —

    The volume type.

  • iops (Numeric, nil) (defaults to: nil) —

    The number of I/O operations per second (IOPS) that the volume supports.

  • throughput (Numeric, nil) (defaults to: nil) —

    The throughput, in mebibyte per second (MiB/s).

end

#throughput ⇒ Numeric? (readonly)

The throughput, in mebibyte per second (MiB/s).

This optional parameter can be a number from 125 - 1000 and is valid only for gp3 volumes.

Returns:

  • (Numeric, nil)
