Instance Attribute Details

#delete_on_termination ⇒ Boolean

Indicates whether the EBS volume is deleted on instance termination.

Returns:

• (Boolean)

  SENSITIVE = []
  include Aws::Structure
end

#ebs_card_index ⇒ Integer

The index of the EBS card. Some instance types support multiple EBS cards. The default EBS card index is 0.

Returns:

• (Integer)

  SENSITIVE = []
  include Aws::Structure
end

#encrypted ⇒ Boolean

Indicates whether the EBS volume is encrypted. Encrypted volumes can only be attached to instances that support Amazon EBS encryption. If you are creating a volume from a snapshot, you can’t specify an encryption value.

Returns:

• (Boolean)

# File 'lib/aws-sdk-ec2/types.rb', line 56122

class LaunchTemplateEbsBlockDeviceRequest < Struct.new(
  :encrypted,
  :delete_on_termination,

  :volume_size,
  :volume_type,
  :throughput,
  :volume_initialization_rate,
  :ebs_card_index)
  SENSITIVE = []
  include Aws::Structure
end

#iops ⇒ Integer

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 supported for ‘io1`, `io2`, and `gp3` volumes only.

#throughput ⇒ Integer

The throughput to provision for a ‘gp3` volume, with a maximum of 2,000 MiB/s.

Valid Range: Minimum value of 125. Maximum value of 2,000.

Returns:

• (Integer)

# File 'lib/aws-sdk-ec2/types.rb', line 56122

end

#volume_initialization_rate ⇒ Integer

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.

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.

  <note markdown=“1”> 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.

  </note>
  

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

For more information, see [ Initialize Amazon EBS volumes] in the *Amazon EC2 User Guide*.

Valid range: 100 - 300 MiB/s

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. The following are the supported volumes sizes for each volume type:

• ‘gp2`: 1 - 16,384 GiB

• ‘io1`: 4 - 16,384 GiB
