Apsara File Storage NAS provides multiple types of file systems. You can select one or more types based on your workloads. This helps you ensure the reliability, security, and continuity of your workloads.
- General-purpose NAS file systems: general file sharing workloads such as Linux or Windows applications for enterprises, container persistent volumes (PVs), web content management, database backup, log storage, genetic computing, Windows user directory, and Linux home directory.
- Extreme NAS file systems: latency-sensitive Linux applications for enterprises, development and test environments for continuous integration and continuous deployment (CI/CD), high-performance web services, online education services, online gaming services, and databases.
