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 - 16,000 IOPSio1
: 100 - 64,000 IOPSio2
: 100 - 256,000 IOPS
This parameter is required for io1
and io2
volume types. The default for gp3
volumes is 3,000 IOPS
. This parameter is not supported for st1
, sc1
, or standard
volume types.
This parameter maps 1:1 with the Iops
parameter of the CreateVolume API in the Amazon EC2 API Reference.
