Describes a block device for an EBS volume.
- DeleteOnTermination (request), deleteOnTermination (response)
Indicates whether the EBS volume is deleted on instance termination.
- Encrypted (request), encrypted (response)
Indicates whether the EBS volume is encrypted. Encrypted Amazon EBS volumes may only be attached to instances that support Amazon EBS encryption.
- Iops (request), iops (response)
The number of I/O operations per second (IOPS) that the volume supports. For
io1, this represents the number of IOPS that are provisioned for the volume. For
gp2, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information about General Purpose SSD baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon Elastic Compute Cloud User Guide.
Constraint: Range is 100-20000 IOPS for
io1volumes and 100-10000 IOPS for
Condition: This parameter is required for requests to create
io1volumes; it is not used in requests to create
- SnapshotId (request), snapshotId (response)
The ID of the snapshot.
- VolumeSize (request), volumeSize (response)
The size of the volume, in GiB.
Constraints: 1-16384 for General Purpose SSD (
gp2), 4-16384 for Provisioned IOPS SSD (
io1), 500-16384 for Throughput Optimized HDD (
st1), 500-16384 for Cold HDD (
sc1), and 1-1024 for Magnetic (
standard) volumes. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size.
Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.
- VolumeType (request), volumeType (response)
The volume type:
standard | io1 | gp2 | sc1 | st1
