deploymentType

(Optional) Choose SCRATCH_1 and SCRATCH_2 deployment types when you need temporary storage and shorter-term processing of data. The SCRATCH_2 deployment type provides in-transit encryption of data and higher burst throughput capacity than SCRATCH_1.

Choose PERSISTENT_1 for longer-term storage and for throughput-focused workloads that aren’t latency-sensitive. PERSISTENT_1 supports encryption of data in transit, and is available in all Amazon Web Services Regions in which FSx for Lustre is available.

Choose PERSISTENT_2 for longer-term storage and for latency-sensitive workloads that require the highest levels of IOPS/throughput. PERSISTENT_2 supports the SSD and Intelligent-Tiering storage classes. You can optionally specify a metadata configuration mode for PERSISTENT_2 which supports increasing metadata performance. PERSISTENT_2 is available in a limited number of Amazon Web Services Regions. For more information, and an up-to-date list of Amazon Web Services Regions in which PERSISTENT_2 is available, see Deployment and storage class options for FSx for Lustre file systems in the Amazon FSx for Lustre User Guide.

If you choose PERSISTENT_2, and you set FileSystemTypeVersion to 2.10, the CreateFileSystem operation fails.

Encryption of data in transit is automatically turned on when you access SCRATCH_2, PERSISTENT_1, and PERSISTENT_2 file systems from Amazon EC2 instances that support automatic encryption in the Amazon Web Services Regions where they are available. For more information about encryption in transit for FSx for Lustre file systems, see Encrypting data in transit in the Amazon FSx for Lustre User Guide.
