Technical Specifications and Limitations

Resilience

VMs are mounted on the POSIX-compliant exported file system inside a local mount point. It provides a fully managed and scalable storage on file level. The service manages all the file storage infrastructure, meaning you can avoid the complexity of deploying, patching, maintaining and scaling complex file system configurations. The service is highly scalable, highly available, and highly durable.

Currently, the Network File Storage is based on the Solid State Drive (SSD) - Standard performance class. Data is stored on two storage servers, providing active-active redundancy. For additional data protection, every storage server is based either on a hardware or a software RAID system.

Performance

Currently, the Network File Storage is based on the SSD Standard performance class, which is recommended for instant data access.

The table below lists the drive types and their specifications:

Drive Type	SSD - Standard
Usage mode	Shared
Minimum and maximum cluster size	2 TiB – 42 TiB
Maximum bandwidth	300 MB/s per 4 TiB with a 1 MiB block size
Maximum Read IOPS	24.000 IOPS per 4 TiB with a 4 KiB block size
Maximum Write IOPS	18.000 IOPS per 4 TiB with a 4 KiB block size

Security

• Encryption at rest involves encrypting data stored on physical media. It protects data from unauthorized access when the data is not actively being used. Network File Storage is based on Block Storage, and it implements encryption at rest.

• Secure deletion ensures that once data is deleted, it cannot be restored, even with access to the physical media. Network File Storage is based on Block Storage, and it implements secure deletion.

Limitations

• Network File Storage is currently limited to German data centers.

• The cluster size cannot be decreased despite deleting some shares or data within them; the cluster will not shrink.
