Deployment options for FSx for Lustre file systems
FSx for Lustre file systems use the persistent deployment type.
Encryption of data at rest is automatically enabled when you create an Amazon FSx for Lustre file system, regardless of the deployment type you use. Scratch 2 and persistent file systems automatically encrypt data in transit when they are accessed from Amazon EC2 instances that support encryption in transit. For more information on encryption, see Data encryption in Amazon FSx for Lustre.
Persistent file systems
Persistent file systems are designed for longer-term storage and workloads. The file servers are highly available, and data is automatically replicated within the same Availability Zone in which the file system is located. The data volumes attached to the file servers are replicated independently from the file servers to which they are attached.
Amazon FSx continuously monitors persistent file systems for hardware failures, and automatically replaces infrastructure components in the event of a failure. On a persistent file system, if a file server becomes unavailable, it's replaced automatically within minutes of failure. During that time, client requests for data on that server transparently retry and eventually succeed after the file server is replaced. Data on persistent file systems is replicated on disks, and any failed disks are automatically replaced transparently.
Use persistent file systems for longer-term storage and for throughput-focused workloads that run for extended periods or indefinitely, and that might be sensitive to disruptions in availability.
Persistent deployment types automatically encrypt data in transit when they are accessed from Amazon EC2 instances that support encryption in transit.
Persistent deployment types can be built on Lustre v2.10 or v2.12, and support SSD (solid state drive) and HDD (hard disk drive) storage types. For SSD storage, the throughput per unit of storage is either 50, 100, or 200 MB/s per tebibyte (TiB). For HDD, throughput per unit of storage is 12 or 40 MB/s per tebibyte.
Persistent_1 deployment types are available in all Amazon Web Services Regions.
