SharedStorage section

(Optional) The shared storage settings for the cluster.

AWS ParallelCluster supports either using Amazon EBS, FSx for ONTAP, and FSx for OpenZFS shared storage volumes, Amazon EFS and FSx for Lustre shared storage file systems, or File Caches.

In the SharedStorage section, you can define either external or managed storage:

  • External storage refers to an existing volume or file system that you manage. AWS ParallelCluster doesn't create or delete it.

  • AWS ParallelCluster managed storage refers to a volume or file system that AWS ParallelCluster created and can delete.

For shared storage quotas and more information about configuring your shared storage, see Shared storage in Using AWS ParallelCluster.

Note

If AWS Batch is used as a scheduler, FSx for Lustre is only available on the cluster head node.

Update policy: If this setting is changed, the update is not allowed.

PerformanceMode (Optional, String)

Specifies the performance mode of the Amazon EFS file system. Supported values are generalPurpose and maxIO. The default value is generalPurpose. For more information, see Performance modes in the Amazon Elastic File System User Guide.

We recommend the generalPurpose performance mode for most file systems.

File systems that use the maxIO performance mode can scale to higher levels of aggregate throughput and operations per second. However, there's a trade-off of slightly higher latencies for most file operations.

Update policy: If this setting is changed, the update is not allowed.

ThroughputMode (Optional, String)

Specifies the throughput mode of the Amazon EFS file system. Supported values are bursting and provisioned. The default value is bursting. When provisioned is used, ProvisionedThroughput must be specified.

Update policy: This setting can be changed during an update.

ProvisionedThroughput (Required when ThroughputMode is provisioned, Integer)

Defines the provisioned throughput (in MiB/s) of the Amazon EFS file system, measured in MiB/s. This corresponds to the ProvisionedThroughputInMibps parameter in the Amazon EFS API Reference.

If you use this parameter, you must set ThroughputMode to provisioned.

The supported range is 1-1024. To request a limit increase, contact AWS Support.

Update policy: This setting can be changed during an update.

FileSystemId (Optional, String)

Defines the Amazon EFS file system ID for an existing file system.

If the cluster is configured to span multiple Availability Zones, you must define a file system mount target in each Availability Zone that's used by the cluster.

When this is specified, only MountDir can be specified. No other EfsSettings can be specified.

If you set this option, the following must be true for the file systems that you define:

  • The file systems have an existing mount target in each of the cluster's Availability Zones, with inbound and outbound NFS traffic allowed from the HeadNode and ComputeNodes. Multiple availability zones are configured in Scheduling / SlurmQueues / Networking / SubnetIds.

    To make sure traffic is allowed between the cluster and file system, you can do one of the following:

    • Configure the security groups of the mount target to allow the traffic to and from the CIDR or prefix list of cluster subnets.

      Note

      AWS ParallelCluster validates that ports are open and that the CIDR or prefix list is configured. AWS ParallelCluster doesn't validate the content of CIDR block or prefix list.

    • Set custom security groups for cluster nodes by using SlurmQueues / Networking / SecurityGroups and HeadNode / Networking / SecurityGroups. The custom security groups must be configured to allow traffic between the cluster and the file system.

      Note

      If all cluster nodes use custom security groups, AWS ParallelCluster only validates that the ports are open. AWS ParallelCluster doesn't validate that the source and destination are properly configured.

Warning

EFS OneZone is only supported if all compute nodes and the head node are in the same Availability Zone. EFS OneZone can have only one mount target.

Note

Multiple Availability Zones is added in AWS ParallelCluster version 3.4.0.

Update policy: If this setting is changed, the update is not allowed.

DeletionPolicy (Optional, String)

Specifies whether the file system should be retained or deleted when the file system is removed from the cluster or the cluster is deleted. The supported values are Delete and Retain. The default value is Delete.

When the DeletionPolicy is set to Delete, a managed file system, with its data, is deleted if the cluster is deleted, or if the file system is removed with a cluster update.

For more information, see Shared storage.

Update policy: This setting can be changed during an update.

Note

DeletionPolicy is supported starting with AWS ParallelCluster version 3.3.0.

FsxLustreSettings

Note

You must define FsxLustreSettings if FsxLustre is specified for StorageType.

(Optional) The settings for an FSx for Lustre file system.

  AutomaticBackupRetentionDays: integer
  CopyTagsToBackups: boolean
  DailyAutomaticBackupStartTime: string
  PerUnitStorageThroughput: integer
  BackupId: string # BackupId cannot coexist with some of the fields
  KmsKeyId: string
  FileSystemId: string # FileSystemId cannot coexist with other fields
  AutoImportPolicy: string
  DriveCacheType: string
  StorageType: string
  DeletionPolicy: string

Update policy: If this setting is changed, the update is not allowed.

Note

If AWS Batch is used as a scheduler, FSx for Lustre is only available on the cluster head node.

FsxLustreSettings properties

When the DeletionPolicy is set to Delete, a managed file system, with its data, is deleted if the cluster is deleted, or if the file system is removed with a cluster update.

For more information, see Shared storage.

StorageCapacity (Required, Integer)

Sets the storage capacity of the FSx for Lustre file system, in GiB. StorageCapacity is required if you're creating a new file system. Do not include StorageCapacity if BackupId or FileSystemId is specified.

  • For SCRATCH_2, PERSISTENT_1, and PERSISTENT_2 deployment types, valid values are 1200 GiB, 2400 GiB, and increments of 2400 GiB.

  • For SCRATCH_1 deployment type, valid values are 1200 GiB, 2400 GiB, and increments of 3600 GiB.

Update policy: If this setting is changed, the update is not allowed.

DeploymentType (Optional, String)

Specifies the deployment type of the FSx for Lustre file system. Supported values are SCRATCH_1, SCRATCH_2, PERSISTENT_1, and PERSISTENT_2. The default value is SCRATCH_2.

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 deployment type for longer term storage and for throughput focused workloads that aren’t latency-sensitive. PERSISTENT_1 supports encryption of data in transit. It's available in all AWS Regions where FSx for Lustre is available.

Choose PERSISTENT_2 deployment type for longer term storage and for latency sensitive workloads that require the highest levels of IOPS and throughput. PERSISTENT_2 supports SSD storage and offers higher PerUnitStorageThroughput (up to 1000 MB/s/TiB). PERSISTENT_2 is available in a limited number of AWS Regions. For more information about deployment types and the list of AWS Regions where PERSISTENT_2 is available, see File system deployment options for FSx for Lustre in the Amazon FSx for Lustre User Guide.

Encryption of data in transit is automatically enabled when you access SCRATCH_2, PERSISTENT_1, or PERSISTENT_2 deployment type file systems from Amazon EC2 instances that support this feature.

Encryption of data in transit for SCRATCH_2, PERSISTENT_1, and PERSISTENT_2 deployment types is supported when accessed from supported instance types in supported AWS Regions. For more information, see Encrypting data in transit in the Amazon FSx for Lustre User Guide.

Note

Support for the PERSISTENT_2 deployment type was added with AWS ParallelCluster version 3.2.0.

Update policy: If this setting is changed, the update is not allowed.

ImportedFileChunkSize (Optional, Integer)

For files that are imported from a data repository, this value determines the stripe count and maximum amount of data for each file (in MiB) that's stored on a single physical disk. The maximum number of disks that a single file can be striped across is limited by the total number of disks that make up the file system.

The default chunk size is 1,024 MiB (1 GiB) and can go as high as 512,000 MiB (500 GiB). Amazon S3 objects have a maximum size of 5 TB.

Note

This parameter isn't supported for file systems using the PERSISTENT_2 deployment type. For instructions on how to configure data repositories associations, see Linking your file system to an S3 bucket in the Amazon FSx for Lustre User Guide.

Update policy: If this setting is changed, the update is not allowed.

DataCompressionType (Optional, String)

Sets the data compression configuration for the FSx for Lustre file system. The supported value is LZ4. LZ4 indicates that data compression is turned on with the LZ4 algorithm. When DataCompressionType isn't specified, data compression is turned off when the file system is created.

For more information, see Lustre data compression.

Update policy: This setting can be changed during an update.

ExportPath (Optional, String)

The path in Amazon S3 where the root of your FSx for Lustre file system is exported. This setting is only supported when the ImportPath parameter is specified. The path must use the same Amazon S3 bucket as specified in ImportPath. You can provide an optional prefix to which new and changed data is to be exported from your FSx for Lustre file system. If an ExportPath value is not provided, FSx for Lustre sets a default export path, s3://import-bucket/FSxLustre[creation-timestamp]. The timestamp is in UTC format, for example s3://import-bucket/FSxLustre20181105T222312Z.

The Amazon S3 export bucket must be the same as the import bucket specified by ImportPath. If you only specify a bucket name, such as s3://import-bucket, you get a 1:1 mapping of file system objects to Amazon S3 bucket objects. This mapping means that the input data in Amazon S3 is overwritten on export. If you provide a custom prefix in the export path, such as s3://import-bucket/[custom-optional-prefix], FSx for Lustre exports the contents of your file system to that export prefix in the Amazon S3 bucket.

Note

This parameter isn't supported for file systems using the PERSISTENT_2 deployment type. Configure data repositories associations as described in Linking your file system to an S3 bucket in the Amazon FSx for Lustre User Guide.

Update policy: If this setting is changed, the update is not allowed.

ImportPath (Optional, String)

The path to the Amazon S3 bucket (including the optional prefix) that you're using as the data repository for your FSx for Lustre file system. The root of your FSx for Lustre file system will be mapped to the root of the Amazon S3 bucket you select. An example is s3://import-bucket/optional-prefix. If you specify a prefix after the Amazon S3 bucket name, only object keys with that prefix are loaded into the file system.

Note

This parameter isn't supported for file systems using the PERSISTENT_2 deployment type. Configure data repositories associations as described in Linking your file system to an S3 bucket in the Amazon FSx for Lustre User Guide.

Update policy: If this setting is changed, the update is not allowed.

WeeklyMaintenanceStartTime (Optional, String)

The preferred start time to perform weekly maintenance. It's in the "d:HH:MM" format in the UTC+0 time zone. For this format, d is the weekday number from 1 through 7, beginning with Monday and ending with Sunday. Quotation marks are required for this field.

Update policy: This setting can be changed during an update.

AutomaticBackupRetentionDays (Optional, Integer)

The number of days to retain automatic backups. Setting this to 0 disables automatic backups. The supported range is 0-90. The default is 0. This setting is only valid for use with PERSISTENT_1 and PERSISTENT_2 deployment types. For more information, see Working with backups in the Amazon FSx for Lustre User Guide.

Update policy: This setting can be changed during an update.

CopyTagsToBackups (Optional, Boolean)

If true, copy the tags for the FSx for Lustre file system to backups. This value defaults to false. If it's set to true, all tags for the file system are copied to all automatic and user-initiated backups where the user doesn't specify 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. This setting is only valid for use with PERSISTENT_1 and PERSISTENT_2 deployment types.

Update policy: If this setting is changed, the update is not allowed.

DailyAutomaticBackupStartTime (Optional, String)

A recurring daily time, in the HH:MM format. HH is the zero-padded hour of the day (00-23). MM is the zero-padded minute of the hour (00-59). For example, 05:00 specifies 5 A.M. daily. This setting is only valid for use with PERSISTENT_1 and PERSISTENT_2 deployment types.

Update policy: This setting can be changed during an update.

PerUnitStorageThroughput (Required for PERSISTENT_1 and PERSISTENT_2 deployment types, Integer)

Describes the amount of read and write throughput for each 1 tebibyte of storage, in MB/s/TiB. File system throughput capacity is calculated by multiplying file system storage capacity (TiB) by the PerUnitStorageThroughput (MB/s/TiB). For a 2.4 TiB file system, provisioning 50 MB/s/TiB of PerUnitStorageThroughput yields 120 MB/s of file system throughput. You pay for the amount of throughput that you provision. This corresponds to the PerUnitStorageThroughput property.

Valid values:

  • PERSISTENT_1 SSD storage: 50, 100, 200 MB/s/TiB.

  • PERSISTENT_1 HDD storage: 12, 40 MB/s/TiB.

  • PERSISTENT_2 SSD storage: 125, 250, 500, 1000 MB/s/TiB.

Update policy: If this setting is changed, the update is not allowed.

BackupId (Optional, String)

Specifies the ID of the backup to use for restoring the FSx for Lustre file system from an existing backup. When the BackupId setting is specified, the AutoImportPolicy, DeploymentType, ExportPath, KmsKeyId, ImportPath, ImportedFileChunkSize, StorageCapacity, and PerUnitStorageThroughput settings must not be specified. These settings are read from the backup. Additionally, the AutoImportPolicy, ExportPath, ImportPath, and ImportedFileChunkSize settings must not be specified. This corresponds to the BackupId property.

Update policy: If this setting is changed, the update is not allowed.

KmsKeyId (Optional, String)

The ID of the AWS Key Management Service (AWS KMS) key ID that's used to encrypt the FSx for Lustre file system's data for persistent FSx for Lustre file systems at rest. If not specified, the FSx for Lustre managed key is used. The SCRATCH_1 and SCRATCH_2 FSx for Lustre file systems are always encrypted at rest using FSx for Lustre managed keys. For more information, see Encrypt in the AWS Key Management Service API Reference.

Update policy: If this setting is changed, the update is not allowed.

FileSystemId (Optional, String)

Specifies the ID of an existing FSx for Lustre file system.

If this option is specified, only the MountDir and FileSystemId settings in the FsxLustreSettings are used. All other settings in the FsxLustreSettings are ignored.

Note

If AWS Batch scheduler is used, FSx for Lustre is only available on the head node.

Note

The file system must be associated to a security group that allows inbound and outbound TCP traffic through ports 988, 1021, 1022, and 1023.

Make sure that traffic is allowed between the cluster and file system by doing one of the following:

  • Configure the security groups of the file system to allow the traffic to and from the CIDR or prefix list of cluster subnets.

    Note

    AWS ParallelCluster validates that ports are open and that the CIDR or prefix list is configured. AWS ParallelCluster doesn't validate the content of CIDR block or prefix list.

  • Set custom security groups for cluster nodes by using SlurmQueues / Networking / SecurityGroups and HeadNode / Networking / SecurityGroups. The custom security groups must be configured to allow traffic between the cluster and the file system.

    Note

    If all cluster nodes use custom security groups, AWS ParallelCluster only validates that the ports are open. AWS ParallelCluster doesn't validate that the source and destination are properly configured.

Update policy: If this setting is changed, the update is not allowed.

AutoImportPolicy (Optional, String)

When you create your FSx for Lustre file system, your existing Amazon S3 objects appear as file and directory listings. Use this property to choose how FSx for Lustre keeps your file and directory listings up to date as you add or modify objects in your linked Amazon S3 bucket. AutoImportPolicy can have the following values:

  • NEW - Automatic import is on. FSx for Lustre automatically imports directory listings of any new objects added to the linked Amazon S3 bucket that do not currently exist in the FSx for Lustre file system.

  • NEW_CHANGED - Automatic import is on. FSx for Lustre automatically imports file and directory listings of any new objects added to the Amazon S3 bucket and any existing objects that are changed in the Amazon S3 bucket after you choose this option.

  • NEW_CHANGED_DELETED - Automatic import is on. FSx for Lustre automatically imports file and directory listings of any new objects added to the Amazon S3 bucket, any existing objects that are changed in the Amazon S3 bucket, and any objects that were deleted in the Amazon S3 bucket after you choose this option.

    Note

    Support for NEW_CHANGED_DELETED was added in AWS ParallelCluster version 3.1.1.

If AutoImportPolicy isn't specified, automatic import is off. FSx for Lustre only updates file and directory listings from the linked Amazon S3 bucket when the file system is created. FSx for Lustre doesn't update file and directory listings for any new or changed objects after choosing this option.

For more information, see Automatically import updates from your S3 bucket in the Amazon FSx for Lustre User Guide.

Note

This parameter isn't supported for file systems using the PERSISTENT_2 deployment type. For instructions on how to configure data repositories associations, see Linking your file system to an S3 bucket in the Amazon FSx for Lustre User Guide.

Update policy: If this setting is changed, the update is not allowed.

DriveCacheType (Optional, String)

Specifies that the file system has an SSD drive cache. This can only be set if the StorageType setting is set to HDD, and the DeploymentType setting is set to PERSISTENT_1. This corresponds to the DriveCacheType property. For more information, see FSx for Lustre deployment options in the Amazon FSx for Lustre User Guide.

The only valid value is READ. To disable the SSD drive cache, don’t specify the DriveCacheType setting.

Update policy: If this setting is changed, the update is not allowed.

StorageType (Optional, String)

Sets the storage type for the FSx for Lustre file system that you're creating. Valid values are SSD and HDD.

  • Set to SSD to use solid state drive storage.

  • Set to HDD to use hard disk drive storage. HDD is supported on PERSISTENT deployment types.

The default value is SSD. For more information, see Storage Type Options in the Amazon FSx for Windows User Guide and Multiple Storage Options in the Amazon FSx for Lustre User Guide.

Update policy: If this setting is changed, the update is not allowed.

DeletionPolicy (Optional, String)

Specifies whether the file system should be retained or deleted when the file system is removed from the cluster or the cluster is deleted. The supported values are Delete and Retain. The default value is Delete.

When the DeletionPolicy is set to Delete, a managed file system, with its data, is deleted if the cluster is deleted, or if the file system is removed with a cluster update.

For more information, see Shared storage.

Update policy: This setting can be changed during an update.

Note

DeletionPolicy is supported starting with AWS ParallelCluster version 3.3.0.

DataRepositoryAssociations (Optional, String)

List of DRAs (up to 8 per file system)

Each data repository association must have a unique Amazon FSx file system directory and a unique S3 bucket or prefix associated with it.

You can not use ExportPath and ImportPath in the FsxLustreSettings at the same time as using DRAs.

Update policy: This setting can be changed during an update.

Name (Required, String)

The name of the DRA. You use this name when you update the settings.

Update policy: If this setting is changed, the update is not allowed.

BatchImportMetaDataOnCreate (Optional, Boolean)

A boolean flag indicating whether an import data repository task to import metadata should run after the data repository association is created. The task runs if this flag is set to true.

Default value: false

Update policy: If this setting is changed, the update is not allowed.

DataRepositoryPath (Required, String)

The path to the Amazon S3 data repository that will be linked to the file system. The path can be an S3 bucket or prefix in the format s3://myBucket/myPrefix/. This path specifies where in the S3 data repository files will be imported from or exported to.

Cannot overlap with other DRAs

Pattern: ^[^\u0000\u0085\u2028\u2029\r\n]{3,4357}$

Minimum: 3

Maximum: 4357

Update policy: If this setting is changed, the update is not allowed.

FileSystemPath (Required, String)

A path on the Amazon FSx for Lustre file system that points to a high-level directory (such as /ns1/) or subdirectory (such as /ns1/subdir/) that will be mapped 1-1 with DataRepositoryPath. The leading forward slash in the name is required. Two data repository associations cannot have overlapping file system paths. For example, if a data repository is associated with file system path /ns1/, then you cannot link another data repository with file system path /ns1/ns2.

This path specifies where in your file system files will be exported from or imported to. This file system directory can be linked to only one Amazon S3 bucket, and no other S3 bucket can be linked to the directory.

Cannot overlap with other DRAs

Note

If you specify only a forward slash (/) as the file system path, you can link only one data repository to the file system. You can only specify "/" as the file system path for the first data repository associated with a file system.

Pattern: ^[^\u0000\u0085\u2028\u2029\r\n]{1,4096}$

Minimum: 1

Maximum: 4096

Update policy: If this setting is changed, the update is not allowed.

ImportedFileChunkSize (Optional, Integer)

For files imported from a data repository, this value determines the stripe count and maximum amount of data per file (in MiB) stored on a single physical disk. The maximum number of disks that a single file can be striped across is limited by the total number of disks that make up the file system or cache.

The default chunk size is 1,024 MiB (1 GiB) and can go as high as 512,000 MiB (500 GiB). Amazon S3 objects have a maximum size of 5 TB.

Minimum: 1

Maximum: 4096

Update policy: This setting can be changed during an update.

AutoExportPolicy (Optional, Array of strings)

The list can contain one or more of the following values:

  • NEW - New files and directories are automatically exported to the data repository as they are added to the file system.

  • CHANGED - Changes to files and directories on the file system are automatically exported to the data repository.

  • DELETED - Files and directories are automatically deleted on the data repository when they are deleted on the file system.

You can define any combination of event types for your AutoExportPolicy.

Maximum: 3

Update policy: This setting can be changed during an update.

AutoImportPolicy (Optional, Array of strings)

The list can contain one or more of the following values:

  • NEW - Amazon FSx automatically imports metadata of files added to the linked S3 bucket that do not currently exist in the FSx file system.

  • CHANGED - Amazon FSx automatically updates file metadata and invalidates existing file content on the file system as files change in the data repository.

  • DELETED - Amazon FSx automatically deletes files on the file system as corresponding files are deleted in the data repository.

You can define any combination of event types for your AutoImportPolicy.

Maximum: 3

Update policy: This setting can be changed during an update.

FsxOntapSettings

Note

You must define FsxOntapSettings if FsxOntap is specified for StorageType.

(Optional) The settings for an FSx for ONTAP file system.

FsxOntapSettings:
  VolumeId: string

FsxOntapSettings properties

VolumeId (Required, String)

Specifies the volume ID of the existing FSx for ONTAP system.

Note

  • If an AWS Batch scheduler is used, FSx for ONTAP is only available on the head node.

  • If the FSx for ONTAP deployment type is Multi-AZ, make sure that the head node subnet's route table is properly configured.

  • Support for FSx for ONTAP was added in AWS ParallelCluster version 3.2.0.

  • The file system must be associated to a security group that allows inbound and outbound TCP and UDP traffic through ports 111, 635, 2049, and 4046.

Make sure traffic is allowed between the cluster and file system by doing one of the following actions:

  • Configure the security groups of the file system to allow the traffic to and from the CIDR or prefix list of cluster subnets.

    Note

    AWS ParallelCluster validates that ports are open and that the CIDR or prefix list is configured. AWS ParallelCluster doesn't validate the content of CIDR block or prefix list.

  • Set custom security groups for cluster nodes by using SlurmQueues / Networking / SecurityGroups and HeadNode / Networking / SecurityGroups. The custom security groups must be configured to allow traffic between the cluster and the file system.

    Note

    If all cluster nodes use custom security groups, AWS ParallelCluster only validates that the ports are open. AWS ParallelCluster doesn't validate that the source and destination are properly configured.

Update policy: If this setting is changed, the update is not allowed.

FsxOpenZfsSettings

Note

You must define FsxOpenZfsSettings if FsxOpenZfs is specified for StorageType.

FileCacheSettings

Note

You must define FileCacheSettings if FileCache is specified for StorageType.

(Optional) The settings for a File Cache.

FileCacheSettings:
  FileCacheId: string

Update policy: If this setting is changed, the update is not allowed.

FileCacheSettings properties

FileCacheId (Required, String)

Specifies the File Cache ID of an existing File Cache.

Note
