Overview

The Lustre metadata performance configuration update for an Amazon FSx for Lustre file system using a PERSISTENT_2 deployment type. You can request an increase in your file system’s Metadata IOPS and/or switch your file system’s metadata configuration mode. For more information, see [Managing metadata performance] in the *Amazon FSx for Lustre User Guide*.

#iops ⇒ Integer

(USER_PROVISIONED mode only) Specifies the number of Metadata IOPS to provision for your file system.
#mode ⇒ String

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

Instance Attribute Details

#iops ⇒ `Integer`

(USER_PROVISIONED mode only) Specifies the number of Metadata IOPS to provision for your 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 and 12000.

The value you provide must be greater than or equal to the current number of Metadata IOPS provisioned for the file system.

Returns:

end

#mode ⇒ `String`

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

To increase the Metadata IOPS or to switch an SSD file system from AUTOMATIC, specify USER_PROVISIONED as the value for this parameter. Then use the Iops parameter to provide a Metadata IOPS value that is greater than or equal to the current number of Metadata IOPS provisioned for the file system.
To switch from USER_PROVISIONED mode on an SSD file system, specify AUTOMATIC as the value for this parameter, but do not input a value for Iops.

<note markdown=“1”> * If you request to switch from USER_PROVISIONED to AUTOMATIC
```
mode and the current Metadata IOPS value is greater than the
automated default, FSx for Lustre rejects the request because
downscaling Metadata IOPS is not supported.
```
- AUTOMATIC mode is not supported on Intelligent-Tiering file systems. For Intelligent-Tiering file systems, use USER_PROVISIONED mode.
