LustreFileSystemConfiguration - Amazon FSx


The configuration for the Amazon FSx for Lustre file system.



The number of days to retain automatic backups. Setting this to 0 disables automatic backups. You can retain automatic backups for a maximum of 90 days. The default is 0.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 90.

Required: No


A boolean flag indicating whether tags on the file system should be copied to backups. If it's set to true, all tags on the file system are copied to all automatic backups and any user-initiated backups where the user doesn't specify any tags. If this value is true, and you specify one or more tags, only the specified tags are copied to backups. If you specify one or more tags when creating a user-initiated backup, no tags are copied from the file system, regardless of this value. (Default = false)

Type: Boolean

Required: No


A recurring daily time, in the format HH:MM. HH is the zero-padded hour of the day (0-23), and MM is the zero-padded minute of the hour. For example, 05:00 specifies 5 AM daily.

Type: String

Length Constraints: Fixed length of 5.

Pattern: ^([01]\d|2[0-3]):?([0-5]\d)$

Required: No


The data repository configuration object for Lustre file systems returned in the response of the CreateFileSystem operation.

Type: DataRepositoryConfiguration object

Required: No


The deployment type of the FSX for Lustre file system. Scratch deployment type is designed for temporary storage and shorter-term processing of data.

SCRATCH_1 and SCRATCH_2 deployment types are best suited for 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.

The PERSISTENT_1 deployment type is used for longer-term storage and workloads and encryption of data in transit. To learn more about deployment types, see FSx for Lustre Deployment Options. (Default = SCRATCH_1)

Type: String


Required: No


The type of drive cache used by PERSISTENT_1 file systems that are provisioned with HDD storage devices. This parameter is required when storage type is HDD. Set to READ, improve the performance for frequently accessed files and allows 20% of the total storage capacity of the file system to be cached.

This parameter is required when StorageType is set to HDD.

Type: String

Valid Values: NONE | READ

Required: No


You use the MountName value when mounting the file system.

For the SCRATCH_1 deployment type, this value is always "fsx". For SCRATCH_2 and PERSISTENT_1 deployment types, this value is a string that is unique within an AWS Region.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 8.

Pattern: ^([A-Za-z0-9_-]{1,8})$

Required: No


Per unit storage throughput represents the megabytes per second of read or write throughput per 1 tebibyte of storage provisioned. File system throughput capacity is equal to Storage capacity (TiB) * PerUnitStorageThroughput (MB/s/TiB). This option is only valid for PERSISTENT_1 deployment types.

Valid values for SSD storage: 50, 100, 200. Valid values for HDD storage: 12, 40.

Type: Integer

Valid Range: Minimum value of 12. Maximum value of 200.

Required: No


The preferred start time to perform weekly maintenance, formatted d:HH:MM in the UTC time zone. d is the weekday number, from 1 through 7, beginning with Monday and ending with Sunday.

Type: String

Length Constraints: Fixed length of 7.

Pattern: ^[1-7]:([01]\d|2[0-3]):?([0-5]\d)$

Required: No
