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 provisions and scales Metadata IOPS for you. For SSD file systems, the number is based on storage capacity. For Intelligent-Tiering file systems, it is based on throughput 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.

  • For SSD file systems, valid values are 1500, 3000, 6000, 12000, and multiples of 12000 up to a maximum of 192000.

  • For Intelligent-Tiering file systems, valid values are 6000, 12000, and multiples of 12000 up to a maximum of 192000.

You can't provision fewer Metadata IOPS than AUTOMATIC mode provisions for your file system.

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's storage capacity for SSD file systems, and on throughput capacity for Intelligent-Tiering file systems.

Type: Integer

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

Required: No
