Properties

AutomaticBackupRetentionDays

Gets and sets the property AutomaticBackupRetentionDays.

public int AutomaticBackupRetentionDays { get; set; }

Property Value

int

CopyTagsToBackups

Gets and sets the property CopyTagsToBackups.

A boolean flag indicating whether tags on the file system are 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) 

public bool CopyTagsToBackups { get; set; }

Property Value

bool

DailyAutomaticBackupStartTime

Gets and sets the property DailyAutomaticBackupStartTime.

public string DailyAutomaticBackupStartTime { get; set; }

Property Value

string

DataCompressionType

Gets and sets the property DataCompressionType.

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. 

public DataCompressionType DataCompressionType { get; set; }

Property Value

DataCompressionType

DataRepositoryConfiguration

Gets and sets the property DataRepositoryConfiguration.

public DataRepositoryConfiguration DataRepositoryConfiguration { get; set; }

Property Value

DataRepositoryConfiguration

DeploymentType

Gets and sets the property DeploymentType.

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 and PERSISTENT_2 deployment type is used for longer-term storage and workloads and encryption of data in transit. PERSISTENT_2 offers higher PerUnitStorageThroughput (up to 1000 MB/s/TiB) along with a lower minimum storage capacity requirement (600 GiB). To learn more about FSx for Lustre deployment types, see FSx for Lustre deployment options.

The default is SCRATCH_1. 

public LustreDeploymentType DeploymentType { get; set; }

Property Value

LustreDeploymentType

DriveCacheType

Gets and sets the property DriveCacheType.

The type of drive cache used by PERSISTENT_1 file systems that are provisioned with HDD storage devices. This parameter is required when StorageType is HDD. When set to READ the file system has an SSD storage cache that is sized to 20% of the file system's storage capacity. This improves the performance for frequently accessed files by caching up to 20% of the total storage capacity.

This parameter is required when StorageType is set to HDD. 

public DriveCacheType DriveCacheType { get; set; }

Property Value

DriveCacheType

LogConfiguration

Gets and sets the property LogConfiguration.

The Lustre logging configuration. Lustre logging writes the enabled log events for your file system to Amazon CloudWatch Logs. 

public LustreLogConfiguration LogConfiguration { get; set; }

Property Value

LustreLogConfiguration

MetadataConfiguration

Gets and sets the property MetadataConfiguration.

The Lustre metadata performance configuration for an Amazon FSx for Lustre file system using a PERSISTENT_2 deployment type. 

public FileSystemLustreMetadataConfiguration MetadataConfiguration { get; set; }

Property Value

FileSystemLustreMetadataConfiguration

MountName

Gets and sets the property MountName.

You use the MountName value when mounting the file system.

For the SCRATCH_1 deployment type, this value is always "fsx". For SCRATCH_2, PERSISTENT_1, and PERSISTENT_2 deployment types, this value is a string that is unique within an Amazon Web Services Region. 

public string MountName { get; set; }

Property Value

string

PerUnitStorageThroughput

Gets and sets the property PerUnitStorageThroughput.

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 and PERSISTENT_2 deployment types.

Valid values:

  • For PERSISTENT_1 SSD storage: 50, 100, 200.

  • For PERSISTENT_1 HDD storage: 12, 40.

  • For PERSISTENT_2 SSD storage: 125, 250, 500, 1000. 

public int PerUnitStorageThroughput { get; set; }

Property Value

int

RootSquashConfiguration

Gets and sets the property RootSquashConfiguration.

The Lustre root squash configuration for an Amazon FSx for Lustre file system. When enabled, root squash restricts root-level access from clients that try to access your file system as a root user. 

public LustreRootSquashConfiguration RootSquashConfiguration { get; set; }

Property Value

LustreRootSquashConfiguration

WeeklyMaintenanceStartTime

Gets and sets the property WeeklyMaintenanceStartTime.

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

public string WeeklyMaintenanceStartTime { get; set; }

Property Value

string
