Class EbsBlockDevice

    • Method Detail

      • iops

        public final Integer iops()

        The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

        The following are the supported values for each volume type:

        • gp3: 3,000 - 80,000 IOPS

        • io1: 100 - 64,000 IOPS

        • io2: 100 - 256,000 IOPS

        For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS.

        This parameter is required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS.

        Returns:

      • availabilityZone

        public final String availabilityZone()

        The Availability Zone where the EBS volume will be created (for example, us-east-1a).

        Either AvailabilityZone or AvailabilityZoneId can be specified, but not both. If neither is specified, Amazon EC2 automatically selects an Availability Zone within the Region.

        This parameter is not supported when using CreateFleet, CreateImage, DescribeImages, RequestSpotFleet, RequestSpotInstances, and RunInstances.

        Returns:
        The Availability Zone where the EBS volume will be created (for example, us-east-1a).

      • encrypted

        public final Boolean encrypted()

        Indicates whether the encryption state of an EBS volume is changed while being restored from a backing snapshot. The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see Amazon EBS encryption in the Amazon EBS User Guide.

        In no case can you remove encryption from an encrypted volume.

        Encrypted volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types.

        This parameter is not returned by DescribeImageAttribute.

        For CreateImage and RegisterImage, whether you can include this parameter, and the allowed values differ depending on the type of block device mapping you are creating.

        • If you are creating a block device mapping for a new (empty) volume, you can include this parameter, and specify either true for an encrypted volume, or false for an unencrypted volume. If you omit this parameter, it defaults to false (unencrypted).

        • If you are creating a block device mapping from an existing encrypted or unencrypted snapshot, you must omit this parameter. If you include this parameter, the request will fail, regardless of the value that you specify.

        • If you are creating a block device mapping from an existing unencrypted volume, you can include this parameter, but you must specify false. If you specify true, the request will fail. In this case, we recommend that you omit the parameter.

        • If you are creating a block device mapping from an existing encrypted volume, you can include this parameter, and specify either true or false. However, if you specify false , the parameter is ignored and the block device mapping is always encrypted. In this case, we recommend that you omit the parameter.

      • volumeInitializationRate

        public final Integer volumeInitializationRate()

        Specifies the Amazon EBS Provisioned Rate for Volume Initialization (volume initialization rate), in MiB/s, at which to download the snapshot blocks from Amazon S3 to the volume. This is also known as volume initialization. Specifying a volume initialization rate ensures that the volume is initialized at a predictable and consistent rate after creation. For more information, see Initialize Amazon EBS volumes in the Amazon EC2 User Guide.

        This parameter is supported only for volumes created from snapshots. Omit this parameter if:

        • You want to create the volume using fast snapshot restore. You must specify a snapshot that is enabled for fast snapshot restore. In this case, the volume is fully initialized at creation.

          If you specify a snapshot that is enabled for fast snapshot restore and a volume initialization rate, the volume will be initialized at the specified rate instead of fast snapshot restore.

        • You want to create a volume that is initialized at the default rate.

        This parameter is not supported when using CreateImage and DescribeImages.

        Valid range: 100 - 300 MiB/s

      • availabilityZoneId

        public final String availabilityZoneId()

        The ID of the Availability Zone where the EBS volume will be created (for example, use1-az1).

        This parameter is not supported when using CreateFleet, CreateImage, DescribeImages, RequestSpotFleet, RequestSpotInstances, and RunInstances.

        Returns:
        The ID of the Availability Zone where the EBS volume will be created (for example, use1-az1 ).
