CreateFileSystemLustreMetadataConfiguration

The Lustre metadata performance configuration for the creation of an Amazon FSx for Lustre file system using a PERSISTENT_2 deployment type. The configuration uses a Metadata IOPS value to set the maximum rate of metadata disk IOPS supported by the file system.

After creation, the file system supports increasing metadata performance. For more information on Metadata IOPS, see Lustre metadata performance configuration in the Amazon FSx for Lustre User Guide.

Mode

The metadata configuration mode for provisioning Metadata IOPS for an FSx for Lustre file system using a PERSISTENT_2 deployment type.

  • In AUTOMATIC mode, FSx for Lustre automatically provisions and scales the number of Metadata IOPS for your file system based on your file system storage capacity.

  • In USER_PROVISIONED mode, you specify the number of Metadata IOPS to provision for your file system.

Type: String

Valid Values: AUTOMATIC | USER_PROVISIONED

Required: Yes

Iops

(USER_PROVISIONED mode only) Specifies the number of Metadata IOPS to provision for the file system. This parameter sets the maximum rate of metadata disk IOPS supported by the file system. Valid values are 1500, 3000, 6000, 12000, and multiples of 12000 up to a maximum of 192000.

Note

Iops doesn’t have a default value. If you're using USER_PROVISIONED mode, you can choose to specify a valid value. If you're using AUTOMATIC mode, you cannot specify a value because FSx for Lustre automatically sets the value based on your file system storage capacity.

Type: Integer

Valid Range: Minimum value of 1500. Maximum value of 192000.

Required: No
