# View file systems

Network-attached storage is a file-level storage architecture that makes stored data more accessible to networked devices.

## About this task

A file system is created for NFS exports.

PowerMax File leverages a mature and robust 64-bit filesystem that is designed for scalability, efficiency, flexibility, resilient and high performance. It supports both traditional and transactional NAS use cases where transactional NAS is limited to VMWare support for PowerMax. Approximately 1.5GB is reserved for metadata. For example, a 100GB filesystem will have a usable capacity of 98.5GB. PowerMax File also supports block-level compression, dedupe and encryption.

See Understanding PowerMax File for storage systems for an overview of PowerMax File.

Click in the top right corner to see a Initial Configuration window that outlines the configuration sequence. An overview of this configuration sequence is provided in Understanding PowerMax File for storage systems.
