LaunchTemplateEbsBlockDeviceRequest¶

Indicates whether the EBS volume is deleted on instance termination.

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

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.

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.

Identifier (key ID, key alias, key ARN, or alias ARN) of the customer managed KMS key to use for EBS encryption.

The ID of the snapshot.

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.

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: 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.

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

• gp3: 1 - 65,536 GiB

• io1: 4 - 16,384 GiB

• io2: 4 - 65,536 GiB

• st1 and sc1: 125 - 16,384 GiB

• standard: 1 - 1024 GiB

The volume type. For more information, see Amazon EBS volume types in the Amazon EBS User Guide.
