class Aws::FSx::Types::LustreFileSystemConfiguration

The configuration for the Amazon FSx for Lustre file system.

@!attribute [rw] weekly_maintenance_start_time

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.
@return [String]

@!attribute [rw] data_repository_configuration

The data repository configuration object for Lustre file systems
returned in the response of the `CreateFileSystem` operation.
@return [Types::DataRepositoryConfiguration]

@!attribute [rw] deployment_type

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][1].
(Default = `SCRATCH_1`)

@return [String]

@!attribute [rw] per_unit_storage_throughput

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.
@return [Integer]

@!attribute [rw] mount_name

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 Amazon Web Services Region.
@return [String]

@!attribute [rw] daily_automatic_backup_start_time

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.
@return [String]

@!attribute [rw] automatic_backup_retention_days

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.
@return [Integer]

@!attribute [rw] copy_tags_to_backups

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)
@return [Boolean]

@!attribute [rw] drive_cache_type

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.
@return [String]

@!attribute [rw] data_compression_type

The data compression configuration for the file system.
`DataCompressionType` can have the following values:

* `NONE` - Data compression is turned off for the file system.

* `LZ4` - Data compression is turned on with the LZ4 algorithm.

For more information, see [Lustre data compression][1].
